• Project Jigsaw: Late for the train: The Q&A

  - by Mark Reinhold

  I recently proposed, to the Java community in general and to the SE 8 (JSR 337) Expert Group in particular, to defer Project Jigsaw from Java 8 to Java 9. I also proposed to aim explicitly for a regular two-year release cycle going forward. Herewith a summary of the key questions I’ve seen in reaction to these proposals, along with answers. Making the decision Q Has the Java SE 8 Expert Group decided whether to defer the addition of a module system and the modularization of the Platform to Java SE 9? A No, it has not yet decided. Q By when do you expect the EG to make this decision? A In the next month or so. Q How can I make sure my voice is heard? A The EG will consider all relevant input from the wider community. If you have a prominent blog, column, or other communication channel then there’s a good chance that we’ve already seen your opinion. If not, you’re welcome to send it to the Java SE 8 Comments List, which is the EG’s official feedback channel. Q What’s the overall tone of the feedback you’ve received? A The feedback has been about evenly divided as to whether Java 8 should be delayed for Jigsaw, Jigsaw should be deferred to Java 9, or some other, usually less-realistic, option should be taken. Project Jigsaw Q Why is Project Jigsaw taking so long? A Project Jigsaw started at Sun, way back in August 2008. Like many efforts during the final years of Sun, it was not well staffed. Jigsaw initially ran on a shoestring, with just a handful of mostly part-time engineers, so progress was slow. During the integration of Sun into Oracle all work on Jigsaw was halted for a time, but it was eventually resumed after a thorough consideration of the alternatives. Project Jigsaw was really only fully staffed about a year ago, around the time that Java 7 shipped. We’ve added a few more engineers to the team since then, but that can’t make up for the inadequate initial staffing and the time lost during the transition. Q So it’s really just a matter of staffing limitations and corporate-integration distractions? A Aside from these difficulties, the other main factor in the duration of the project is the sheer technical difficulty of modularizing the JDK. Q Why is modularizing the JDK so hard? A There are two main reasons. The first is that the JDK code base is deeply interconnected at both the API and the implementation levels, having been built over many years primarily in the style of a monolithic software system. We’ve spent considerable effort eliminating or at least simplifying as many API and implementation dependences as possible, so that both the Platform and its implementations can be presented as a coherent set of interdependent modules, but some particularly thorny cases remain. Q What’s the second reason? A We want to maintain as much compatibility with prior releases as possible, most especially for existing classpath-based applications but also, to the extent feasible, for applications composed of modules. Q Is modularizing the JDK even necessary? Can’t you just put it in one big module? A Modularizing the JDK, and more specifically modularizing the Java SE Platform, will enable standard yet flexible Java runtime configurations scaling from large servers down to small embedded devices. In the long term it will enable the convergence of Java SE with the higher-end Java ME Platforms. Q Is Project Jigsaw just about modularizing the JDK? A As originally conceived, Project Jigsaw was indeed focused primarily upon modularizing the JDK. The growing demand for a truly standard module system for the Java Platform, which could be used not just for the Platform itself but also for libraries and applications built on top of it, later motivated expanding the scope of the effort. Q As a developer, why should I care about Project Jigsaw? A The introduction of a modular Java Platform will, in the long term, fundamentally change the way that Java implementations, libraries, frameworks, tools, and applications are designed, built, and deployed. Q How much progress has Project Jigsaw made? A We’ve actually made a lot of progress. Much of the core functionality of the module system has been prototyped and works at both compile time and run time. We’ve extended the Java programming language with module declarations, worked out a structure for modular source trees and corresponding compiled-class trees, and implemented these features in javac. We’ve defined an efficient module-file format, extended the JVM to bootstrap a modular JRE, and designed and implemented a preliminary API. We’ve used the module system to make a good first cut at dividing the JDK and the Java SE API into a coherent set of modules. Among other things, we’re currently working to retrofit the java.util.ServiceLoader API to support modular services. Q I want to help! How can I get involved? A Check out the project page, read the draft requirements and design overview documents, download the latest prototype build, and play with it. You can tell us what you think, and follow the rest of our work in real time, on the jigsaw-dev list. The Java Platform Module System JSR Q What’s the relationship between Project Jigsaw and the eventual Java Platform Module System JSR? A At a high level, Project Jigsaw has two phases. In the first phase we’re exploring an approach to modularity that’s markedly different from that of existing Java modularity solutions. We’ve assumed that we can change the Java programming language, the virtual machine, and the APIs. Doing so enables a design which can strongly enforce module boundaries in all program phases, from compilation to deployment to execution. That, in turn, leads to better usability, diagnosability, security, and performance. The ultimate goal of the first phase is produce a working prototype which can inform the work of the Module-System JSR EG. Q What will happen in the second phase of Project Jigsaw? A The second phase will produce the reference implementation of the specification created by the Module-System JSR EG. The EG might ultimately choose an entirely different approach than the one we’re exploring now. If and when that happens then Project Jigsaw will change course as necessary, but either way I think that the end result will be better for having been informed by our current work. Maven & OSGi Q Why not just use Maven? A Maven is a software project management and comprehension tool. As such it can be seen as a kind of build-time module system but, by its nature, it does nothing to support modularity at run time. Q Why not just adopt OSGi? A OSGi is a rich dynamic component system which includes not just a module system but also a life-cycle model and a dynamic service registry. The latter two facilities are useful to some kinds of sophisticated applications, but I don’t think they’re of wide enough interest to be standardized as part of the Java SE Platform. Q Okay, then why not just adopt the module layer of OSGi? A The OSGi module layer is not operative at compile time; it only addresses modularity during packaging, deployment, and execution. As it stands, moreover, it’s useful for library and application modules but, since it’s built strictly on top of the Java SE Platform, it can’t be used to modularize the Platform itself. Q If Maven addresses modularity at build time, and the OSGi module layer addresses modularity during deployment and at run time, then why not just use the two together, as many developers already do? A The combination of Maven and OSGi is certainly very useful in practice today. These systems have, however, been built on top of the existing Java platform; they have not been able to change the platform itself. This means, among other things, that module boundaries are weakly enforced, if at all, which makes it difficult to diagnose configuration errors and impossible to run untrusted code securely. The prototype Jigsaw module system, by contrast, aims to define a platform-level solution which extends both the language and the JVM in order to enforce module boundaries strongly and uniformly in all program phases. Q If the EG chooses an approach like the one currently being taken in the Jigsaw prototype, will Maven and OSGi be made obsolete? A No, not at all! No matter what approach is taken, to ensure wide adoption it’s essential that the standard Java Platform Module System interact well with Maven. Applications that depend upon the sophisticated features of OSGi will no doubt continue to use OSGi, so it’s critical that implementations of OSGi be able to run on top of the Java module system and, if suitably modified, support OSGi bundles that depend upon Java modules. Ideas for how to do that are currently being explored in Project Penrose. Java 8 & Java 9 Q Without Jigsaw, won’t Java 8 be a pretty boring release? A No, far from it! It’s still slated to include the widely-anticipated Project Lambda (JSR 335), work on which has been going very well, along with the new Date/Time API (JSR 310), Type Annotations (JSR 308), and a set of smaller features already in progress. Q Won’t deferring Jigsaw to Java 9 delay the eventual convergence of the higher-end Java ME Platforms with Java SE? A It will slow that transition, but it will not stop it. To allow progress toward that convergence to be made with Java 8 I’ve suggested to the Java SE 8 EG that we consider specifying a small number of Profiles which would allow compact configurations of the SE Platform to be built and deployed. Q If Jigsaw is deferred to Java 9, would the Oracle engineers currently working on it be reassigned to other Java 8 features and then return to working on Jigsaw again after Java 8 ships? A No, these engineers would continue to work primarily on Jigsaw from now until Java 9 ships. Q Why not drop Lambda and finish Jigsaw instead? A Even if the engineers currently working on Lambda could instantly switch over to Jigsaw and immediately become productive—which of course they can’t—there are less than nine months remaining in the Java 8 schedule for work on major features. That’s just not enough time for the broad review, testing, and feedback which such a fundamental change to the Java Platform requires. Q Why not ship the module system in Java 8, and then modularize the platform in Java 9? A If we deliver a module system in one release but don’t use it to modularize the JDK until some later release then we run a big risk of getting something fundamentally wrong. If that happens then we’d have to fix it in the later release, and fixing fundamental design flaws after the fact almost always leads to a poor end result. Q Why not ship Jigsaw in an 8.5 release, less than two years after 8? Or why not just ship a new release every year, rather than every other year? A Many more developers work on the JDK today than a couple of years ago, both because Oracle has dramatically increased its own investment and because other organizations and individuals have joined the OpenJDK Community. Collectively we don’t, however, have the bandwidth required to ship and then provide long-term support for a big JDK release more frequently than about every other year. Q What’s the feedback been on the two-year release-cycle proposal? A For just about every comment that we should release more frequently, so that new features are available sooner, there’s been another asking for an even slower release cycle so that large teams of enterprise developers who ship mission-critical applications have a chance to migrate at a comfortable pace.

• Should one replace the usage addJSONData of jqGrid to the usage of setGridParam(), and trigger('relo

  - by Oleg

  Hi everybody who use jqGrid! I am a new on stackoverflow.com and it seems to me that a lot of peoples who use stackoverflow.com are not only the persons who have a problem which must be quickly solved. A lot of people read stackoverflow.com to look at well-known things from the other side. Sometime perhaps the reason is a self-training (to stay in the good form) during solving of problems other people. For all these gays, who not want only to solve his problem is my question. I wrote recently an answer to the question "jqGrid display default “loading” message when updating a table / on custom update". During writing of the answer I thought: why he uses addJSONData() function for refresh of data in the grid instead of changing URL with respect of setGridParam() and refreshing jqGrid data with respect of trigger('reloadGrid')? At the beginning I wanted to recommend using of 'reloadGrid', but after thinking about this I understood, that I am not quite sure what the best way is. At least I can't explain in two sentences why I prefer the second way. So I decide that it could be an interesting subject of a discussion. So to be exactly: We have a typical situation. We have a web page with at least one jqGrid and some other controls like combo-boxes (selects), checkboxes etc. which give user possibilities to change scope on information displayed in a jqGrid. Typically we define some event handler like jQuery("#selector").change(myRefresh).keyup(myKeyRefresh) and we need reload the jqGrid contain based on users choose. After reading and analyzing of the information from additional users input we can refresh jqGrid contain in at least two ways: Make call of $.ajax() manual and then inside of success or complete handle of $.ajax call jQuery.parseJSON() (or eval) and then call addJSONData function of jqGrid. I found a lot of examples on stackoverflow.com who use addJSONData. Update url of jqGrid based on users input, reset current page number to 1 and optionally change the caption of the grid. All these can be done with respect of setGridParam(), and optionally setCaption() jqGrid methods. At the end one call trigger('reloadGrid') method of the grid. To construct the url, by the way I use mostly jQuery.param function to be sure, that I all url parameters packed correctly with respect of encodeURIComponent. I want that we discuss advantages and disadvantages of both ways. I use currently the second way, so I start with advantages of this one. One can say me: I call existing Web Service, convert received data to the jqGrid format and call addJSONData. This is the reason why I use addJSONData method! OK, I choose another way. jqGrid can make a call of the Web Service directly and fill results inside of grid. There are a lot of jqGrid options, which allow you to customize this process. First of all, one can delete or rename any standard parameter sent to server with respect of prmNames option of jqGrid or add any more additional parameters with respect of postData option (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:options). One can modify all constructed parameters immediately before jqGrid makes corresponding $.ajax request by defining of serializeGridData() function (one more option of jqGrid). More than that, one can change every $.ajax parameter by setting ajaxGridOptions option of jqGrid. I use ajaxGridOptions: {contentType: "application/json"} for example as a general setting of $.jgrid.defaults. The ajaxGridOptions option is very powerful. With respect of ajaxGridOptions option one can redefine any parameter of $.ajax request sending by jqGrid, like error, complete and beforeSend events. I see potentially interesting to define dataFilter event to be able makes any modification of the row data responded from the server. One more argument for using of trigger('reloadGrid') way is blocking of jqGrid during ajax request processing. Mostly I use parameter loadui: 'block' to block jqGrid during JSON request sending to server. With respect of jQuery blockUI plugin http://malsup.com/jquery/block/ one can block more parts of web page as the grid only. To do this one can call jQuery('#main').block({ message: '<h1>Die Daten werden vom Server geladen...</h1>' }); before calling of trigger('reloadGrid') method and jQuery('#main').unblock() inside of loadComplete and loadError functions. The loadui option could be set to 'disable' in this case. So I don’t see why the function addJSONData() should be used. Can somebody who use addJSONData() function explain me advantages of its usage? Should one replace the usage addJSONData of jqGrid to the usage of setGridParam(), and trigger('reloadGrid')? I am opened to the discussion.

• How to reduce iOS AVPlayer start delay

  - by Bernt Habermeier

  Note, for the below question: All assets are local on the device -- no network streaming is taking place. The videos contain audio tracks. I'm working on an iOS application that requires playing video files with minimum delay to start the video clip in question. Unfortunately we do not know what specific video clip is next until we actually need to start it up. Specifically: When one video clip is playing, we will know what the next set of (roughly) 10 video clips are, but we don't know which one exactly, until it comes time to 'immediately' play the next clip. What I've done to look at actual start delays is to call addBoundaryTimeObserverForTimes on the video player, with a time period of one millisecond to see when the video actually started to play, and I take the difference of that time stamp with the first place in the code that indicates which asset to start playing. From what I've seen thus-far, I have found that using the combination of AVAsset loading, and then creating an AVPlayerItem from that once it's ready, and then waiting for AVPlayerStatusReadyToPlay before I call play, tends to take between 1 and 3 seconds to start the clip. I've since switched to what I think is roughly equivalent: calling [AVPlayerItem playerItemWithURL:] and waiting for AVPlayerItemStatusReadyToPlay to play. Roughly same performance. One thing I'm observing is that the first AVPlayer item load is slower than the rest. Seems one idea is to pre-flight the AVPlayer with a short / empty asset before trying to play the first video might be of good general practice. [http://stackoverflow.com/questions/900461/slow-start-for-avaudioplayer-the-first-time-a-sound-is-played] I'd love to get the video start times down as much as possible, and have some ideas of things to experiment with, but would like some guidance from anyone that might be able to help. Update: idea 7, below, as-implemented yields switching times of around 500 ms. This is an improvement, but it it'd be nice to get this even faster. Idea 1: Use N AVPlayers (won't work) Using ~ 10 AVPPlayer objects and start-and-pause all ~ 10 clips, and once we know which one we really need, switch to, and un-pause the correct AVPlayer, and start all over again for the next cycle. I don't think this works, because I've read there is roughly a limit of 4 active AVPlayer's in iOS. There was someone asking about this on StackOverflow here, and found out about the 4 AVPlayer limit: fast-switching-between-videos-using-avfoundation Idea 2: Use AVQueuePlayer (won't work) I don't believe that shoving 10 AVPlayerItems into an AVQueuePlayer would pre-load them all for seamless start. AVQueuePlayer is a queue, and I think it really only makes the next video in the queue ready for immediate playback. I don't know which one out of ~10 videos we do want to play back, until it's time to start that one. ios-avplayer-video-preloading Idea 3: Load, Play, and retain AVPlayerItems in background (not 100% sure yet -- but not looking good) I'm looking at if there is any benefit to load and play the first second of each video clip in the background (suppress video and audio output), and keep a reference to each AVPlayerItem, and when we know which item needs to be played for real, swap that one in, and swap the background AVPlayer with the active one. Rinse and Repeat. The theory would be that recently played AVPlayer/AVPlayerItem's may still hold some prepared resources which would make subsequent playback faster. So far, I have not seen benefits from this, but I might not have the AVPlayerLayer setup correctly for the background. I doubt this will really improve things from what I've seen. Idea 4: Use a different file format -- maybe one that is faster to load? I'm currently using .m4v's (video-MPEG4) H.264 format. I have not played around with other formats, but it may well be that some formats are faster to decode / get ready than others. Possible still using video-MPEG4 but with a different codec, or maybe quicktime? Maybe a lossless video format where decoding / setup is faster? Idea 5: Combination of lossless video format + AVQueuePlayer If there is a video format that is fast to load, but maybe where the file size is insane, one idea might be to pre-prepare the first 10 seconds of each video clip with a version that is boated but faster to load, but back that up with an asset that is encoded in H.264. Use an AVQueuePlayer, and add the first 10 seconds in the uncompressed file format, and follow that up with one that is in H.264 which gets up to 10 seconds of prepare/preload time. So I'd get 'the best' of both worlds: fast start times, but also benefits from a more compact format. Idea 6: Use a non-standard AVPlayer / write my own / use someone else's Given my needs, maybe I can't use AVPlayer, but have to resort to AVAssetReader, and decode the first few seconds (possibly write raw file to disk), and when it comes to playback, make use of the raw format to play it back fast. Seems like a huge project to me, and if I go about it in a naive way, it's unclear / unlikely to even work better. Each decoded and uncompressed video frame is 2.25 MB. Naively speaking -- if we go with ~ 30 fps for the video, I'd end up with ~60 MB/s read-from-disk requirement, which is probably impossible / pushing it. Obviously we'd have to do some level of image compression (perhaps native openGL/es compression formats via PVRTC)... but that's kind crazy. Maybe there is a library out there that I can use? Idea 7: Combine everything into a single movie asset, and seekToTime One idea that might be easier than some of the above, is to combine everything into a single movie, and use seekToTime. The thing is that we'd be jumping all around the place. Essentially random access into the movie. I think this may actually work out okay: avplayer-movie-playing-lag-in-ios5 Which approach do you think would be best? So far, I've not made that much progress in terms of reducing the lag.

• CSS Dropdown Menu issues

  - by Simon Hume

  Can anyone help with a small problem. I've got a nice simple CSS dropdown menu http://www.cinderellahair.co.uk/new/CSSDropdown.html The problem I have is when you rollover a menu item that has children which are wider than the content, it pushes the whole menu right. Aside of shortening the child menu links down, is there any tweak I can make to my CSS to stop this happening? CSS Code: /* General */ #cssdropdown, #cssdropdown ul { list-style: none; } #cssdropdown, #cssdropdown * { padding: 0; margin: 0; } #cssdropdown {padding:43px 0px 0px 0px;} /* Head links */ #cssdropdown li.headlink { margin:0px 40px 0px -1px; float: left; background-color: #e9e9e9;} #cssdropdown li.headlink a { display: block; padding: 0px 0px 0px 5px; text-decoration:none; } #cssdropdown li.headlink a:hover { text-decoration:underline; } /* Child lists and links */ #cssdropdown li.headlink ul { display: none; text-align: left; padding:10px 0px 0px 0px; font-size:12px; float:left;} #cssdropdown li.headlink:hover ul { display: block; } #cssdropdown li.headlink ul li a { padding: 5px; height: 17px; } #cssdropdown li.headlink ul li a:hover { background-color: #333; } /* Pretty styling */ body { font-family:Georgia, "Times New Roman", Times, serif; font-size: 16px; } #cssdropdown a { color: grey; } #cssdropdown ul li a:hover { text-decoration: none; } #cssdropdown li.headlink { background-color: white; } #cssdropdown li.headlink ul { padding-bottom: 10px;} HTML: <ul id="cssdropdown"> <li class="headlink"><a href="http://www.cinderellahair.co.uk/new/index.php">HOME</a></li> <li class="headlink"><a href="http://www.cinderellahair.co.uk/new/gallery/gallery.php">GALLERY</a> <ul> <li><a href="http://amazon.com/">CELEBRITY</a></li> <li><a href="http://ebay.com/">BEFORE &amp; AFTER</a></li> <li><a href="http://craigslist.com/">HAIR TYPES</a></li> </ul> </li> <li class="headlink"><a href="http://www.cinderellahair.co.uk/new/about-cinderella-hair-extensions/about-us.php">ABOUT US</a> <ul> <li><a href="http://amazon.com/">WHY CHOOSE CINDERELLA</a></li> <li><a href="http://ebay.com/">TESTIMONIALS</a></li> <li><a href="http://craigslist.com/">MINI VIDEO CLIPS</a></li> <li><a href="http://craigslist.com/">OUR HAIR PRODUCTS</a></li> </ul> </li> <li class="headlink"><a href="http://www.cinderellahair.co.uk/new/news-and-offers/news.php">NEWS &amp; OFFERS</a> <ul> <li><a href="http://amazon.com/">VERA WANG FREE GIVEAWAY</a></li> <li><a href="http://ebay.com/">CINDERELLA ON TV</a></li> <li><a href="http://craigslist.com/">CINDERELLA IN THE PRESS</a></li> <li><a href="http://craigslist.com/">CINDRELLA NEWSLETTERS</a></li> </ul> </li> <li class="headlink"><a href="http://www.cinderellahair.co.uk/new/cinderella-salon/salon-finder.php">SALON FINDER</a></li> </ul> JS Code: $(document).ready(function(){ $('#cssdropdown li.headlink').hover( function() { $('ul', this).css('display', 'block'); }, function() { $('ul', this).css('display', 'none'); }); }); Full code is on the link above, just view source.

• How to configure hibernate-tools with maven to generate hibernate.cfg.xml, *.hbm.xml, POJOs and DAOs

  - by mmm

  Hi, can any one tell me how to force maven to precede mapping .hbm.xml files in the automatically generated hibernate.cfg.xml file with package path? My general idea is, I'd like to use hibernate-tools via maven to generate the persistence layer for my application. So, I need the hibernate.cfg.xml, then all my_table_names.hbm.xml and at the end the POJO's generated. Yet, the hbm2java goal won't work as I put *.hbm.xml files into the src/main/resources/package/path/ folder but hbm2cfgxml specifies the mapping files only by table name, i.e.: <mapping resource="MyTableName.hbm.xml" /> So the big question is: how can I configure hbm2cfgxml so that hibernate.cfg.xml looks like below: <mapping resource="package/path/MyTableName.hbm.xml" /> My pom.xml looks like this at the moment: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>hibernate3-maven-plugin</artifactId> <version>2.2</version> <executions> <execution> <id>hbm2cfgxml</id> <phase>generate-sources</phase> <goals> <goal>hbm2cfgxml</goal> </goals> <inherited>false</inherited> <configuration> <components> <component> <name>hbm2cfgxml</name> <implemetation>jdbcconfiguration</implementation> <outputDirectory>src/main/resources/</outputDirectory> </component> </components> <componentProperties> <packagename>package.path</packageName> <configurationFile>src/main/resources/hibernate.cfg.xml</configurationFile> </componentProperties> </configuration> </execution> </executions> </plugin> And then the second question: is there a way to tell maven to copy resources to the target folder before executing hbm2java? At the moment I'm using mvn clean resources:resources generate-sources for that, but there must be a better way. Thanks for any help. Update: @Pascal: Thank you for your help. The path to mappings works fine now, I don't know what was wrong before, though. Maybe there is some issue with writing to hibernate.cfg.xml while reading database config from it (though the file gets updated). I've deleted the file hibernate.cfg.xml, replaced it with database.properties and run the goals hbm2cfgxml and hbm2hbmxml. I also don't use the outputDirectory nor configurationfile in those goals anymore. As a result the files hibernate.cfg.xml and all *.hbm.xml are being generated into my target/hibernate3/generated-mappings/ folder, which is the default value. Then I updated the hbm2java goal with the following: <componentProperties> <packagename>package.name</packagename> <configurationfile>target/hibernate3/generated-mappings/hibernate.cfg.xml</configurationfile> </componentProperties> But then I get the following: [INFO] --- hibernate3-maven-plugin:2.2:hbm2java (hbm2java) @ project.persistence --- [INFO] using configuration task. [INFO] Configuration XML file loaded: file:/C:/Documents%20and%20Settings/mmm/workspace/project.persistence/target/hibernate3/generated-mappings/hibernate.cfg.xml 12:15:17,484 INFO org.hibernate.cfg.Configuration - configuring from url: file:/C:/Documents%20and%20Settings/mmm/workspace/project.persistence/target/hibernate3/generated-mappings/hibernate.cfg.xml 12:15:19,046 INFO org.hibernate.cfg.Configuration - Reading mappings from resource : package.name/Messages.hbm.xml [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.codehaus.mojo:hibernate3-maven-plugin:2.2:hbm2java (hbm2java) on project project.persistence: Execution hbm2java of goal org.codehaus.mojo:hibernate3-maven-plugin:2.2:hbm2java failed: resource: package/name/Messages.hbm.xml not found How do I deal with that? Of course I could add: <outputDirectory>src/main/resources/package/name</outputDirectory> to the hbm2hbmxml goal, but I think this is not the best approach, or is it? Is there a way to keep all the generated code and resources away from the src/ folder? I assume, the goal of this approach is not to generate any sources into my src/main/java or /resources folder, but to keep the generated code in the target folder. As I generally agree with this point of view, I'd like to continue with that eventually executing hbm2dao and packaging the project to be used as a generated persistence layer component from the business layer. Is this also what you meant?

• ruby on rails configuration

  - by Themasterhimself

  Im using the following guide for getting started with rails for ubuntu 9.10. http://guides.rails.info/getting_started.html I have installed both ruby and gem. gokul@gokul-laptop:~$ ruby -v ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux] gokul@gokul-laptop:~$ gem -v 1.3.6 gokul@gokul-laptop:~$ For rails, gokul@gokul-laptop:~$sudo gem install rails doesnt seem to give any response. so used the synaptic package manager for installing it. And it seems to have installed correctly. gokul@gokul-laptop:~$ rails Usage: /usr/bin/rails /path/to/your/app [options] Options: -r, --ruby=path Path to the Ruby binary of your choice (otherwise scripts use env, dispatchers current path). Default: /usr/bin/ruby1.8 -d, --database=name Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite2/sqlite3/frontbase/ibm_db). Default: sqlite3 -D, --with-dispatchers Add CGI/FastCGI/mod_ruby dispatches code to generated application skeleton Default: false --freeze Freeze Rails in vendor/rails from the gems generating the skeleton Default: false -m, --template=path Use an application template that lives at path (can be a filesystem path or URL). Default: (none) Rails Info: -v, --version Show the Rails version number and quit. -h, --help Show this help message and quit. General Options: -p, --pretend Run but do not make any changes. -f, --force Overwrite files that already exist. -s, --skip Skip files that already exist. -q, --quiet Suppress normal output. -t, --backtrace Debugging: show backtrace on errors. -c, --svn Modify files with subversion.

• UITableView issue when using separate delegate/dataSource

  - by Adam Alexander

  General Description: To start with what works, I have a UITableView which has been placed onto an Xcode-generated view using Interface Builder. The view's File Owner is set to an Xcode-generated subclass of UIViewController. To this subclass I have added working implementations of numberOfSectionsInTableView: tableView:numberOfRowsInSection: and tableView:cellForRowAtIndexPath: and the Table View's dataSource and delegate are connected to this class via the File Owner in Interface Builder. The above configuration works with no problems. The issue occurs when I want to move this Table View's dataSource and delegate implementations out to a separate class, most likely because there are other controls on the View besides the Table View and I'd like to move the Table View-related code out to its own class. To accomplish this, I try the following: Create a new subclass of UITableViewController in Xcode Move the known-good implementations of numberOfSectionsInTableView: tableView:numberOfRowsInSection: and tableView:cellForRowAtIndexPath: to the new subclass Drag a Table View Controller to the top level of the existing XIB in InterfaceBuilder, delete the View/TableView that are automatically created for this Table View Controller, then set the Table View Controller's class to match the new subclass Remove the previously-working Table View's existing dataSource and delegate connections and connect them to the new Table View Controller When complete, I do not have a working Table View. I end up with one of three outcomes which can seemingly happen at random: When the Table View loads, I get a runtime error indicating I am sending tableView:cellForRowAtIndexPath: to an object which does not recognize it When the Table View loads, the project breaks into the debugger without error There is no error, but the Table View does not appear With some debugging and having created a basic project just to reproduce this issue, I am usually seeing the 3rd option above (no error but no visible table view). I added some NSLog calls and found that although numberOfSectionsInTableView and numberOfRowsInSection are both getting called, cellForRowAtIndexPath is not. I am convinced I'm missing something really simple and was hoping the answer may be obvious to someone with more experience than I have. If this doesn't turn out to be an easy answer I would be happy to update with some code or a sample project. Thanks for your time! Complete steps to reproduce: Create a new iPhone OS, View-Based Application in Xcode and call it TableTest Open TableTestViewController.xib in Interface Builder and drag a Table View onto the provided view surface. Connect the Table View's dataSource and delegate outlets to File's Owner, which should already represent the TableTestViewController class. Save your changes Back in Xcode, add the following code to TableTestViewController.m: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { NSLog(@"Returning num sections"); return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"Returning num rows"); return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"Trying to return cell"); static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } cell.text = @"Hello"; NSLog(@"Returning cell"); return cell; } Build and Go, and you should see the word Hello appear in the TableView Now to attempt to move this TableView's logic out to a separate class, first create a new file in Xcode, choosing UITableViewController subclass and calling the class TableTestTableViewController Remove the above code snippet from TableTestViewController.m and place it into TableTestTableViewController.m, replacing the default implementation of these three methods with ours. Back in Interface Builder within the same TableTestViewController.xib file, drag a Table View Controller into the main IB window and delete the new Table View object that automatically came with it Set the class for this new Table View Controller to TableTestTableViewController Remove the dataSource and delegate bindings from the existing, previously-working Table View and reconnect the same two bindings to the new Table Test Table View Controller we created. Save changes, Build and Go, and if you're getting the results I'm getting, note the Table View no longer functions properly Solution: With some more troubleshooting and some assistance from the iPhone Developer Forums at https://devforums.apple.com/message/5453, I've documented a solution! The main UIViewController subclass of the project needs an outlet pointing to the UITableViewController instance. To accomplish this, simply add the following to the primary view's header (TableTestViewController.h): #import "TableTestTableViewController.h" and IBOutlet TableTestTableViewController *myTableViewController; Then, in Interface Builder, connect the new outlet from File's Owner to Table Test Table View Controller in the main IB window. No changes are necessary in the UI part of the XIB. Simply having this outlet in place, even though no user code directly uses it, resolves the problem completely. Thanks to those who've helped and credit goes to BaldEagle on the iPhone Developer Forums for finding the solution.

• MDI WinForm application and duplicate child form memory leak

  - by Steve

  This is a WinForm MDI application problem (.net framework 3.0). It will be described in C#. Sorry it is a bit long because I try to make things as clear as possible. I have a MDI application. At some point I find that one MDI child form is never released. There is a menu that creates the MDI child form and show it. When the MDI child form is closed, it is supposed to be destroyed and the memory taken by it should be given back to .net. But to my surprise, this is not true. All the MDI child form instances are kept in memory. This is obviously a "memory leak". Well, it is not a real leak in .net. It is just that I think the closed form should be dead but somehow there is at least one unknown reference from outside world that still connect with the closed form. I read some articles on the Web. Some says that when the MDI child form is closing, I should unwire all the event handlers, otherwise some event handlers may keep my form alive. Some says that DataBindings should be cleaned before the form is closing otherwise the DataBindings will add references to some global Hashtable and thus keep my form alive. My form contains quite a lot things. Many event handlers and many DataBindings and many BindingSources and few suspected controls containing user control and HelpProvider. I create a big method that unwires all the event handlers from all the relevant controls, clear all the DataBindings and DataSources. The HelpProvider and user controls are disposed carefully. At the end, I find that, I don't have to clear DataBindings and DataSources. Event handlers are definitely causing the problem. And MDI form structure also contributes to something. During my experiments, I find that, if you create a MDI child form, even if you close it, there will still be one instance in the memory. The reference is from PropertyStore of the main form. This means, unless the main form is closed (application ends), there will always be one instance of MDI child form in the memory. The good news is that, no matter how many times you open and close the child form, there will be only one instance, not a big "leak". When it comes to event handlers, things become more tricky. I have to address that, all the event handlers on my form are anonymous event handlers. Here is an example code: //On MDI child form's design code... Button btnSave = new Button(); btnSave.Click += new System.EventHandler(btnSave_Click); Where btnSave_Click is also a method in MDI child form. The above is always the case for various controls and various types of event. To me, this is a bi-directional circular reference. btnSave keeps a reference of MDI child form via the event handler. MDI child form keeps a reference of btnSave instance. To me again, such bi-directional circular reference should not cause any problem for .net's garbage collector. This means that I do not have to explicitly unwire the event when the form is being disposed: btnSave.Click -= btnSave_Click; But the truth is not so. For some event handlers, they are safe. Ignoring them do not cause any duplicate instance. For some other event handlers, they will cause one instance remaining in the memory (similar effect as the MDI form structure, but this time caused by the hanging event handlers). For some other event handlers, they will cause every instance opened in the memory. I am totally confused about the differences between these three types of event handlers. The controls are created in the same way and the event is attached in the same way. What is the difference? (Don't tell me it is the event handle methods that make difference.) Anyone has experience of this wired scenario and has an answer for me? Thanks a lot. So now, for safety issue, I will have to unwire all the event handlers when the form is being disposed. That will be a long list of similar code for each control. Is there a general way of removing events from controls in recursive way using reflection? What about performance issue? That's the end of my story and I am still in the middle of my problem. For any help, I thank you.

• JPA Entity (in multiple persistence-unit) in OSGi (Spring DM) Environnement is confusing me.

  - by Vincent Demeester

  Hi, I'm a bit confused about a strange behavior of my JPA's related objects. I have three bundle : The User bundle does contain some user-related objects, but mainly the User object. The Energy bundle does contain some energy-related objects, and particularly a ConsumptionTerminal which contains a List of User. The Index bundle does contain an Index object that has no dependency at all. My OSGi environment is the following : A DataSource bundle that provide 2 services : dataSource and jpaVendorAdapter. The three bundles. They consume dataSource and jpaVendorAdapter. Their module-context.xml file look like : And they all have a persistence.xml file : User <?xml version="1.0" encoding="UTF-8"?> <persistence> <persistence-unit name="securityPU" transaction-type="JTA"> <jta-data-source>java:/securityDataSourceService</jta-data-source> <class>net.nextep.amundsen.security.domain.User</class> <!-- [...] --> <exclude-unlisted-classes>true</exclude-unlisted-classes> <properties> <property name="eclipselink.logging.level" value="INFO" /> <property name="eclipselink.ddl-generation" value="create-tables" /> <property name="eclipselink.ddl-generation.output-mode" value="database" /> <property name="eclipselink.orm.throw.exceptions" value="true" /> </properties> </persistence-unit> </persistence> Energy <?xml version="1.0" encoding="UTF-8"?> <persistence> <persistence-unit name="energyPU" transaction-type="JTA"> <jta-data-source>java:/securityDataSourceService</jta-data-source> <class>net.nextep.amundsen.security.domain.User</class> <class>net.nextep.amundsen.energy.domain.User</class> <!-- [...] --> <exclude-unlisted-classes>true</exclude-unlisted-classes> <properties> <property name="eclipselink.logging.level" value="INFO" /> <property name="eclipselink.ddl-generation" value="create-tables" /> <property name="eclipselink.ddl-generation.output-mode" value="database" /> <property name="eclipselink.orm.throw.exceptions" value="true" /> </properties> </persistence-unit> </persistence> Index : This one has the most simple persistence.xml with just the Index class (no shared Class). I'm using named @PersistenceUnit annotation like @PersitenceUnit(name = 'securityPU') (for the User bundle). And finally, I'm using EclipseLink as Jpa provider and Spring DM (+ Spring DM Server in the development process) The problem is the following : When the User bundle is deployed, I'm able to persist User objects. When the User bundle and Energy bundles are both deployed, I'm not able to persist User objects (neither the Energy object). But I don't have any exception at all ! There is no problem at all with the Index bundle. The bug is dataSource independent (I tried with PostgreSQL and MySQL so far). My first conclusion was that the <class>net.nextep.amundsen.security.domain.User</class> in both persistence unit was causing the trouble. I tried without it (and hiding the User dependent object in the Energy bundle) but it failed too. I'm a bit confused about that bug. I'm also not quite sure about the transaction management in this context. I wasn't the one who designed this architecture (but I tell my intern OK without testing it.. shame on me) but if I could understand this bug and maybe fix it without rewrite the bundle (and break my intern work), I would appreciate. Am I doing something wrong ? (it's obvious, but what..) Did I miss something while reading documentation ? By the way, I'm also looking for some best practices or advices when it comes to JPA, EclipseLink (or whatever JPA Provider) and Spring DM (and OSGi in general). I found interesting slides from Mike Keith about this topic (by browsing Stackoverflow).

• How to send mail from ASP.NET with IIS6 SMTP in a dedicated server?

  - by Julio César

  Hi. I'm trying to configure a dedicated server that runs ASP.NET to send mail through the local IIS SMTP server but mail is getting stuck in the Queue folder and doesn't get delivered. I'm using this code in an .aspx page to test: <%@ Page Language="C#" AutoEventWireup="true" %> <% new System.Net.Mail.SmtpClient("localhost").Send("[email protected]", "[email protected]", "testing...", "Hello, world.com"); %> Then, I added the following to the Web.config file: <system.net> <mailSettings> <smtp> <network host="localhost"/> </smtp> </mailSettings> </system.net> In the IIS Manager I've changed the following in the properties of the "Default SMTP Virtual Server".

Thanks @mattlant This is a dedicated server that's why I'm installing the SMTP manually. EDIT: I use exchange so its a little different, but its called a smart host in exchange, but in plain SMTP service config i think its called something else. Cant remember exactly the setting name. Thank you for pointing me at the Smart host field. Mail is getting delivered now. In the Default SMTP Virtual Server properties, the Delivery tab, click Advanced and fill the "Smart host" field with the address that your provider gives you. In my case (GoDaddy) it was k2smtpout.secureserver.net. More info here: http://help.godaddy.com/article/1283

• "Expected initializer before '<' token" in header file

  I'm pretty new to programming and am generally confused by header files and includes. I would like help with an immediate compile problem and would appreciate general suggestions about cleaner, safer, slicker ways to write my code. I'm currently repackaging a lot of code that used to be in main() into a Simulation class. I'm getting a compile error with the header file for this class. I'm compiling with gcc version 4.2.1. // Simulation.h #ifndef SIMULATION_H #define SIMULATION_H #include <cstdlib> #include <iostream> #include <cmath> #include <string> #include <fstream> #include <set> #include <boost/multi_index_container.hpp> #include <boost/multi_index/hashed_index.hpp> #include <boost/multi_index/member.hpp> #include <boost/multi_index/ordered_index.hpp> #include <boost/multi_index/mem_fun.hpp> #include <boost/multi_index/composite_key.hpp> #include <boost/shared_ptr.hpp> #include <boost/tuple/tuple_comparison.hpp> #include <boost/tuple/tuple_io.hpp> #include "Parameters.h" #include "Host.h" #include "rng.h" #include "Event.h" #include "Rdraws.h" typedef multi_index_container< // line 33 - first error boost::shared_ptr< Host >, indexed_by< hashed_unique< const_mem_fun<Host,int,&Host::getID> >, // 0 - ID index ordered_non_unique< tag<age>,const_mem_fun<Host,int,&Host::getAgeInY> >, // 1 - Age index hashed_non_unique< tag<household>,const_mem_fun<Host,int,&Host::getHousehold> >, // 2 - Household index ordered_non_unique< // 3 - Eligible by age & household tag<aeh>, composite_key< Host, const_mem_fun<Host,int,&Host::getAgeInY>, const_mem_fun<Host,bool,&Host::isEligible>, const_mem_fun<Host,int,&Host::getHousehold> > >, ordered_non_unique< // 4 - Eligible by household (all single adults) tag<eh>, composite_key< Host, const_mem_fun<Host,bool,&Host::isEligible>, const_mem_fun<Host,int,&Host::getHousehold> > >, ordered_non_unique< // 5 - Household & age tag<ah>, composite_key< Host, const_mem_fun<Host,int,&Host::getHousehold>, const_mem_fun<Host,int,&Host::getAgeInY> > > > // end indexed_by > HostContainer; typedef std::set<int> HHSet; class Simulation { public: Simulation( int sid ); ~Simulation(); // MEMBER FUNCTION PROTOTYPES void runDemSim( void ); void runEpidSim( void ); void ageHost( int id ); int calcPartnerAge( int a ); void executeEvent( Event & te ); void killHost( int id ); void pairHost( int id ); void partner2Hosts( int id1, int id2 ); void fledgeHost( int id ); void birthHost( int id ); void calcSI( void ); double beta_ij_h( int ai, int aj, int s ); double beta_ij_nh( int ai, int aj, int s ); private: // SIMULATION OBJECTS double t; double outputStrobe; int idCtr; int hholdCtr; int simID; RNG rgen; HostContainer allHosts; // shared_ptr to Hosts - line 102 - second error HHSet allHouseholds; int numInfecteds[ INIT_NUM_AGE_CATS ][ INIT_NUM_STYPES ]; EventPQ currentEvents; // STREAM MANAGEMENT void writeOutput(); void initOutput(); void closeOutput(); std::ofstream ageDistStream; std::ofstream ageDistTStream; std::ofstream hhDistStream; std::ofstream hhDistTStream; std::string ageDistFile; std::string ageDistTFile; std::string hhDistFile; std::string hhDistTFile; }; #endif I'm hoping the other files aren't so relevant to this problem.

It seems like I have all the right Boost #includes for the HostContainer to be understood. What else could be going wrong? I would appreciate immediate suggestions, troubleshooting tips, and other advice about my code. My plan is to create a "HostContainer.h" file that includes the typedef and structs that define its tags, similar to what I'm doing in "Event.h" for the EventPQ container. I'm assuming this is legal and good form.

My strategy has been to represent utf-8 chars as unsigned char so that appropriate overloads of functions can be used for the two character types. e.g. namespace MyStuff { typedef uchar utf8_t; typedef std::basic_string<utf8_t> U8string; } void SomeFunc(std::string &s); void SomeFunc(std::wstring &s); void SomeFunc(MyStuff::U8string &s); This all works pretty well until I try to use a stringstream. std::basic_ostringstream<MyStuff::utf8_t> ostr; ostr << 1; MSVC Visual C++ Express V10 won't compile this: c:\program files\microsoft visual studio 10.0\vc\include\xlocmon(213): warning C4273: 'id' : inconsistent dll linkage c:\program files\microsoft visual studio 10.0\vc\include\xlocnum(65) : see previous definition of 'public: static std::locale::id std::numpunct<unsigned char>::id' c:\program files\microsoft visual studio 10.0\vc\include\xlocnum(65) : while compiling class template static data member 'std::locale::id std::numpunct<_Elem>::id' with [ _Elem=Tk::utf8_t ] c:\program files\microsoft visual studio 10.0\vc\include\xlocnum(1149) : see reference to function template instantiation 'const _Facet &std::use_facet<std::numpunct<_Elem>>(const std::locale &)' being compiled with [ _Facet=std::numpunct<Tk::utf8_t>, _Elem=Tk::utf8_t ] c:\program files\microsoft visual studio 10.0\vc\include\xlocnum(1143) : while compiling class template member function 'std::ostreambuf_iterator<_Elem,_Traits> std::num_put<_Elem,_OutIt>:: do_put(_OutIt,std::ios_base &,_Elem,std::_Bool) const' with [ _Elem=Tk::utf8_t, _Traits=std::char_traits<Tk::utf8_t>, _OutIt=std::ostreambuf_iterator<Tk::utf8_t,std::char_traits<Tk::utf8_t>> ] c:\program files\microsoft visual studio 10.0\vc\include\ostream(295) : see reference to class template instantiation 'std::num_put<_Elem,_OutIt>' being compiled with [ _Elem=Tk::utf8_t, _OutIt=std::ostreambuf_iterator<Tk::utf8_t,std::char_traits<Tk::utf8_t>> ] c:\program files\microsoft visual studio 10.0\vc\include\ostream(281) : while compiling class template member function 'std::basic_ostream<_Elem,_Traits> & std::basic_ostream<_Elem,_Traits>::operator <<(int)' with [ _Elem=Tk::utf8_t, _Traits=std::char_traits<Tk::utf8_t> ] c:\program files\microsoft visual studio 10.0\vc\include\sstream(526) : see reference to class template instantiation 'std::basic_ostream<_Elem,_Traits>' being compiled with [ _Elem=Tk::utf8_t, _Traits=std::char_traits<Tk::utf8_t> ] c:\users\michael\dvl\tmp\console\console.cpp(23) : see reference to class template instantiation 'std::basic_ostringstream<_Elem,_Traits,_Alloc>' being compiled with [ _Elem=Tk::utf8_t, _Traits=std::char_traits<Tk::utf8_t>, _Alloc=std::allocator<uchar> ] . c:\program files\microsoft visual studio 10.0\vc\include\xlocmon(213): error C2491: 'std::numpunct<_Elem>::id' : definition of dllimport static data member not allowed with [ _Elem=Tk::utf8_t ] Any ideas? ** Edited 19 June 2012 ** OK, I've gotten closer to understanding this, but not how to solve it. As we all know, static class variables get defined twice: once in the class definition and once outside the class definition which establishes storage space. e.g. // in .h file class CFoo { // ... static int x; }; // in .cpp file int CFoo::x = 42; Now in the VC10 headers we get something like this: template<class _Elem> class numpunct : public locale::facet { // ... _CRTIMP2_PURE static locale::id id; // ... } When the header is included in an application, _CRTIMP2_PURE is defined as __declspec(dllimport), which means that the variable is imported from a dll. Now the header also contains the following template<class _Elem> locale::id numpunct<_Elem>::id; Note the absence of the __declspec(dllimport) qualifier. i.e. The class declaration says that the static linkage of the id variable is in the dll, but for the general case, it gets declared outside the dll. For the known cases, there are specialisations. template locale::id numpunct<char>::id; template locale::id numpunct<wchar_t>::id; These are protected by #ifs so that they are only included when building the DLL. They are excluded otherwise. i.e. the char and wchar_t versions of numpunct ARE inside the dll So we have the class definition saying that id's storage is in the DLL, but that is only true for the char and wchar_t specialisations, meaning that my unsigned char version is doomed. :-( The only way forward that I can think of is to create my own specialisation: basically copying it from the header file and fixing it. This raises many issues. Anybody have a better idea?

• iphone Dev - activity indicator with NSThread not working on Nav controller table view

  - by Frames84

  I really can't get this to work, basically when my JSON feeds loads I want the indicator to show, then hide when it's stopped. It loads top level menu items 1st "Publishing, Broadcasting, Marketing Services", then when Broadcasting is selected it loads a feed using the JSON framework hosted on Google. Round this load I call startIndicator and stopIndicator using the NSThread. Have I missed something? @implementation GeneralNewsTableViewController @synthesize dataList; @synthesize generalNewsDetailViewController; @synthesize atLevel; -(void) startIndicator { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc ] init ];

• How to manage memory using classes in Objective-C?

  - by Flipper

  This is my first time creating an iPhone App and I am having difficulty with the memory management because I have never had to deal with it before. I have a UITableViewController and it all works fine until I try to scroll down in the simulator. It crashes saying that it cannot allocate that much memory. I have narrowed it down to where the crash is occurring: - (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // Dequeue or create a cell UITableViewCellStyle style = UITableViewCellStyleDefault; UITableViewCell *cell = [aTableView dequeueReusableCellWithIdentifier:@"BaseCell"]; if (!cell) cell = [[[UITableViewCell alloc] initWithStyle:style reuseIdentifier:@"BaseCell"] autorelease]; NSString* crayon; // Retrieve the crayon and its color if (aTableView == self.tableView) { crayon = [[[self.sectionArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row] getName]; } else { crayon = [FILTEREDKEYS objectAtIndex:indexPath.row]; } cell.textLabel.text = crayon; if (![crayon hasPrefix:@"White"]) cell.textLabel.textColor = [self.crayonColors objectForKey:crayon]; else cell.textLabel.textColor = [UIColor blackColor]; return cell; } Here is the getName method: - (NSString*)getName { return name; } name is defined as: @property (nonatomic, retain) NSString *name; Now sectionArray is an NSMutableArray with instances of a class that I created Term in it. Term has a method getName that returns a NSString*. The problem seems to be the part of where crayon is being set and getName is being called. I have tried adding autorelease, release, and other stuff like that but that just causes the entire app to crash before even launching. Also if I do: cell.textLabel.text = @"test"; //crayon; /*if (![crayon hasPrefix:@"White"]) cell.textLabel.textColor = [self.crayonColors objectForKey:crayon]; else cell.textLabel.textColor = [UIColor blackColor];*/ Then I get no error whatsoever and it all scrolls just fine. Thanks in advance for the help! Edit: Here is the full Log of when I try to run the app and the error it gives when it crashes: [Session started at 2010-12-29 04:23:38 -0500.] [Session started at 2010-12-29 04:23:44 -0500.] GNU gdb 6.3.50-20050815 (Apple version gdb-967) (Tue Jul 14 02:11:58 UTC 2009) Copyright 2004 Free Software Foundation, Inc.

• How can I make a jQuery UI 'draggable()' div draggable for touchscreen?

  - by artlung

  I have a jQuery UI draggable() that works in Firefox and Chrome. The user interface concept is basically click to create a "post-it" type item. Basically, I click or tap on div#everything (100% high and wide) that listens for clicks, and an input textarea displays. You add text, and then when you're done it saves it. You can drag this element around. That is working on normal browsers, but on an iPad I can test with I can't drag the items around. If I touch to select (it then dims slightly), I can't then drag it. It won't drag left or right at all. I can drag up or down, but I'm not dragging the individual div, I'm dragging the whole webpage. So here's the code I use to capture clicks: $('#everything').bind('click', function(e){ var elem = document.createElement('DIV'); STATE.top = e.pageY; STATE.left = e.pageX; var e = $(elem).css({ top: STATE.top, left: STATE.left }).html('<textarea></textarea>') .addClass('instance') .bind('click', function(event){ return false; }); $(this).append(e); }); And here's the code I use to "save" the note and turn the input div into just a display div: $('textarea').live('mouseleave', function(){ var val = jQuery.trim($(this).val()); STATE.content = val; if (val == '') { $(this).parent().remove(); } else { var div = $(this).parent(); div.text(val).css({ height: '30px' }); STATE.height = 30; if ( div.width() !== div[0].clientWidth || div.height () !== div[0].clientHeight ) { while (div.width() !== div[0].clientWidth || div.height () !== div[0].clientHeight) { var h = div.height() + 10; STATE.height = h; div.css({ height: (h) + 'px' }); // element just got scrollbars } } STATE.guid = uniqueID() div.addClass('savedNote').attr('id', STATE.guid).draggable({ stop: function() { var offset = $(this).offset(); STATE.guid = $(this).attr('id'); STATE.top = offset.top; STATE.left = offset.left; STATE.content = $(this).text(); STATE.height = $(this).height(); STATE.save(); } }); STATE.save(); $(this).remove(); } }); And I have this code when I load the page for saved notes: $('.savedNote').draggable({ stop: function() { STATE.guid = $(this).attr('id'); var offset = $(this).offset(); STATE.top = offset.top; STATE.left = offset.left; STATE.content = $(this).text(); STATE.height = $(this).height(); STATE.save(); } }); My STATE object handles saving the notes. Onload, this is the whole html body: <body> <div id="everything"></div> <div class="instance savedNote" id="iddd1b0969-c634-8876-75a9-b274ff87186b" style="top:134px;left:715px;height:30px;">Whatever dude</div> <div class="instance savedNote" id="id8a129f06-7d0c-3cb3-9212-0f38a8445700" style="top:131px;left:347px;height:30px;">Appointment 11:45am</div> <div class="instance savedNote" id="ide92e3d13-afe8-79d7-bc03-818d4c7a471f" style="top:144px;left:65px;height:80px;">What do you think of a board where you can add writing as much as possible?</div> <div class="instance savedNote" id="idef7fe420-4c19-cfec-36b6-272f1e9b5df5" style="top:301px;left:534px;height:30px;">This was submitted</div> <div class="instance savedNote" id="id93b3b56f-5e23-1bd1-ddc1-9be41f1efb44" style="top:390px;left:217px;height:30px;">Hello world from iPad.</div> </body> So, my question is really: how can I make this work better on iPad? I'm not set on jQuery UI, I'm wondering if this is something I'm doing wrong with jQuery UI, or jQuery, or whether there may be better frameworks for doing cross-platform/backward compatible draggable() elements that will work for touchscreen UIs. More general comments about how to write UI components like this would be welcome as well. Thanks!

• Boost::Interprocess Container Container Resizing No Default Constructor

  - by CuppM

  Hi, After combing through the Boost::Interprocess documentation and Google searches, I think I've found the reason/workaround to my issue. Everything I've found, as I understand it, seems to be hinting at this, but doesn't come out and say "do this because...". But if anyone can verify this I would appreciate it. I'm writing a series of classes that represent a large lookup of information that is stored in memory for fast performance in a parallelized application. Because of the size of data and multiple processes that run at a time on one machine, we're using Boost::Interprocess for shared memory to have a single copy of the structures. I looked at the Boost::Interprocess documentation and examples, and they typedef classes for shared memory strings, string vectors, int vector vectors, etc. And when they "use" them in their examples, they just construct them passing the allocator and maybe insert one item that they've constructed elsewhere. Like on this page: http://www.boost.org/doc/libs/1_42_0/doc/html/interprocess/allocators_containers.html So following their examples, I created a header file with typedefs for shared memory classes: namespace shm { namespace bip = boost::interprocess; // General/Utility Types typedef bip::managed_shared_memory::segment_manager segment_manager_t; typedef bip::allocator<void, segment_manager_t> void_allocator; // Integer Types typedef bip::allocator<int, segment_manager_t> int_allocator; typedef bip::vector<int, int_allocator> int_vector; // String Types typedef bip::allocator<char, segment_manager_t> char_allocator; typedef bip::basic_string<char, std::char_traits<char>, char_allocator> string; typedef bip::allocator<string, segment_manager_t> string_allocator; typedef bip::vector<string, string_allocator> string_vector; typedef bip::allocator<string_vector, segment_manager_t> string_vector_allocator; typedef bip::vector<string_vector, string_vector_allocator> string_vector_vector; } Then for one of my lookup table classes, it's defined something like this: class Details { public: Details(const shm::void_allocator & alloc) : m_Ids(alloc), m_Labels(alloc), m_Values(alloc) { } ~Details() {} int Read(BinaryReader & br); private: shm::int_vector m_Ids; shm::string_vector m_Labels; shm::string_vector_vector m_Values; }; int Details::Read(BinaryReader & br) { int num = br.ReadInt(); m_Ids.resize(num); m_Labels.resize(num); m_Values.resize(num); for (int i = 0; i < num; i++) { m_Ids[i] = br.ReadInt(); m_Labels[i] = br.ReadString().c_str(); int count = br.ReadInt(); m_Value[i].resize(count); for (int j = 0; j < count; j++) { m_Value[i][j] = br.ReadString().c_str(); } } } But when I compile it, I get the error: 'boost::interprocess::allocator<T,SegmentManager>::allocator' : no appropriate default constructor available And it's due to the resize() calls on the vector objects. Because the allocator types do not have a empty constructor (they take a const segment_manager_t &) and it's trying to create a default object for each location. So in order for it to work, I have to get an allocator object and pass a default value object on resize. Like this: int Details::Read(BinaryReader & br) { shm::void_allocator alloc(m_Ids.get_allocator()); int num = br.ReadInt(); m_Ids.resize(num); m_Labels.resize(num, shm::string(alloc)); m_Values.resize(num, shm::string_vector(alloc)); for (int i = 0; i < num; i++) { m_Ids[i] = br.ReadInt(); m_Labels[i] = br.ReadString().c_str(); int count = br.ReadInt(); m_Value[i].resize(count, shm::string(alloc)); for (int j = 0; j < count; j++) { m_Value[i][j] = br.ReadString().c_str(); } } } Is this the best/correct way of doing it? Or am I missing something. Thanks!

• Design pattern for parsing data that will be grouped to two different ways and flipped

  - by lewisblackfan

  I'm looking for an easily maintainable and extendable design model for a script to parse an excel workbook into two separate workbooks after pulling data from other locations like the command line, and a database. The high level details are as follows. I need to parse an excel workbook containing a sheet that lists unique question names, the only reliable information that can be parsed from the question name is the book code that identifies the title and edition of the textbook the question is associated with, the rest of the question name is not standardized well enough to be reliably parsed by computer. The general form of the question name is best described by the following regular expression. '^(\w+)\s(\w{1,2})\.(\w{1,2})\.(\w{1,3})\.(\w{1,3}\.)*$' The first sub-pattern is the book code, the second sub-pattern is 90% of the time the chapter, and the rest of the sub-patterns could be section, problem type, problem number, or question type information. There is no simple logic, at least not one I can find. There will be a minimum of three other columns in this spreadsheet; one column will be the chapter the question is associated with, the second will be the section within the chapter the question is associated with, and the third will be some kind of asset indicated by a uniform resource locator. 1 | 1 | qname1 | url | description | url | description ... 1 | 1 | qname2 | url | description 1 | 1 | qname3 | url | description | url | description | url | The asset can be indicated by a full or partial uniform resource locator, the partial url will need to be completed before it can be fed into the application. There theoretically could be no limit to the number of asset columns, the assets will be grouped in columns by type. Some times additional data will have to be retrieved from a database or combined with the book code before the asset url is complete and can be understood by the application that will be using the asset. The type is an abstraction, there are eight types right now, each with their own logic in how the uniform resource locator is handled and or completed, and I have to add a new type and its logic every three or four months. For each asset url there is the possibility of a description column, a character string for display in the application, but not always. (I've already worked out validating the description text, and squashing MSs obscure code page down to something 7-bit ascii can handle.) Now that all the details are filled-in I can get to the actual problem of parsing the file. I need to split the information in this excel workbook into two separate workbooks. The first workbook will group all the questions by section in rows. With the first cell being the section doublet and the rest of the cells in the row are the question names. 1.1 | qname1 | qname2 | qname3 | qname4 | 1.2 | qname1 | qname2 | qname3 | 1.3 | qname1 | qname2 | qname3 | qname4 | qname5 There is no set number of questions for each section as you can see from the above example. The second workbook is more complicated, there is one row per asset, and question names that have more than one asset will be duplicated. There will be four or five columns on this sheet. The first is the question name for the asset, the second is a media type used to select the correct icon for the asset in the application, the third is string representing the asset type, the four is the full and complete uniform resource locator for the asset, and the fifth columns is the optional text description for the asset. q1 | mtype1 | atype1 | url | description q1 | mtype2 | atype2 | url | description q1 | mtype2 | atype3 | url | description q2 | mtype1 | atype1 | url | description q2 | mtype2 | atype3 | url | description For the original six types I did have a script that parsed the source excel workbook into the other two excel workbooks, and I was able to add two more types until I ran aground on the implementation of the ninth type and tenth types. What broke my script was the fact that the ninth type is actually a sub-type of one of the original six, but with entirely different logic, and my mostly procedural script could not accommodate without duplicating a lot of code. I also had a lot of bugs in the script and will be writing the test first on this time around. I'm stuck with the format for the resulting two workbooks, this script is glue code, development went ahead with the project without bothering to get a complete spec from the sponsor. I work for the same company as the developers but in the editorial department, editorial is co-sponsor of the project, and am expected to fix pesky details like this (I'm foaming at the mouth as I type this). I've tried factories, I've tried different object models, but each resulting workbook is so different when I find a design that works for generating one workbook the code is not really usable for generating the other. What I would really like are ideas about a maintainable and extensible design for parsing the source workbook into both workbooks with maximum code reuse, and or sympathy.

• Content display problems when using Suckerfish menus with 960.gs and IE

  - by Cedar Jensen

  I'm using 960.gs layout and when I add the suckerfish menu as part of the content to one of the grids, the contents of adjacent siblings bleed through the menu in all versions of IE. In the listed html below, the text from 'belowFoldSection' will appear through the menu when it is visible and has enough items to make it span over 2nd section. However, the contents of 'introSummary' will be underneath the menu, as expected. I've set the z-index for #nav and #nav ul in my css and this of course makes it work in FF, Chrome and Safari, but not in IE (because IE incorrectly assigns child elements its own z-index). If I change the .grid_nn class 'position' attribute (set by default in the 960 template) from 'relative' to absolute, this fixes it in IE. However, it is my understanding that I don't want the child elements of the 'container_12' to be taken out of the flow of the document and want them positioned relative to the .container_12's starting point. (Changing the attribute to absolute causes other general layout problems) Can anyone suggest a work-around? My html: <div class="container_12"> <!--First section where menu lives--> <div class="grid_12" id="mainSection"> <div class="grid_4 alpha" id="intro"> <p>Start of menu here</p> <div id="subMenu"> <ul id="nav"> <li><a href="#">Item 1</a> <ul> <li><a href="#">Burrowing gobies</a></li> <li><a href="#">Dartfishes</a></li> <li><a href="#">Eellike gobies</a></li> <!--10 more for longer list --> </ul> </li> <li><a href="#">Item 2</a> <ul> <li><a href="#">Remoras</a></li> <li><a href="#">Tilefishes</a></li> <!--10 more for longer list --> </ul> </li> <li><a href="#">Item 3</a> <ul> <li><a href="#">Climbing perches</a></li> <li><a href="#">Labyrinthfishes</a></li> <li><a href="#">Kissing gouramis</a></li> <!--10 more for longer list --> </ul> </li> </ul> <div id="introSummary"> <h1>PERCIFORMES!

• Techniques for modeling a dynamic dataflow with Java concurrency API

  - by Maian

  Is there an elegant way to model a dynamic dataflow in Java? By dataflow, I mean there are various types of tasks, and these tasks can be "connected" arbitrarily, such that when a task finishes, successor tasks are executed in parallel using the finished tasks output as input, or when multiple tasks finish, their output is aggregated in a successor task (see flow-based programming). By dynamic, I mean that the type and number of successors tasks when a task finishes depends on the output of that finished task, so for example, task A may spawn task B if it has a certain output, but may spawn task C if has a different output. Another way of putting it is that each task (or set of tasks) is responsible for determining what the next tasks are. Sample dataflow for rendering a webpage: I have as task types: file downloader, HTML/CSS renderer, HTML parser/DOM builder, image renderer, JavaScript parser, JavaScript interpreter. File downloader task for HTML file HTML parser/DOM builder task File downloader task for each embedded file/link If image, image renderer If external JavaScript, JavaScript parser JavaScript interpreter Otherwise, just store in some var/field in HTML parser task JavaScript parser for each embedded script JavaScript interpreter Wait for above tasks to finish, then HTML/CSS renderer (obviously not optimal or perfectly correct, but this is simple) I'm not saying the solution needs to be some comprehensive framework (in fact, the closer to the JDK API, the better), and I absolutely don't want something as heavyweight is say Spring Web Flow or some declarative markup or other DSL. To be more specific, I'm trying to think of a good way to model this in Java with Callables, Executors, ExecutorCompletionServices, and perhaps various synchronizer classes (like Semaphore or CountDownLatch). There are a couple use cases and requirements: Don't make any assumptions on what executor(s) the tasks will run on. In fact, to simplify, just assume there's only one executor. It can be a fixed thread pool executor, so a naive implementation can result in deadlocks (e.g. imagine a task that submits another task and then blocks until that subtask is finished, and now imagine several of these tasks using up all the threads). To simplify, assume that the data is not streamed between tasks (task output-succeeding task input) - the finishing task and succeeding task won't exist together, so the input data to the succeeding task will not be changed by the preceeding task (since it's already done). There are only a couple operations that the dataflow "engine" should be able to handle: A mechanism where a task can queue more tasks A mechanism whereby a successor task is not queued until all the required input tasks are finished A mechanism whereby the main thread (or other threads not managed by the executor) blocks until the flow is finished A mechanism whereby the main thread (or other threads not managed by the executor) blocks until certain tasks have finished Since the dataflow is dynamic (depends on input/state of the task), the activation of these mechanisms should occur within the task code, e.g. the code in a Callable is itself responsible for queueing more Callables. The dataflow "internals" should not be exposed to the tasks (Callables) themselves - only the operations listed above should be available to the task. Note that the type of the data is not necessarily the same for all tasks, e.g. a file download task may accept a File as input but will output a String. If a task throws an uncaught exception (indicating some fatal error requiring all dataflow processing to stop), it must propagate up to the thread that initiated the dataflow as quickly as possible and cancel all tasks (or something fancier like a fatal error handler). Tasks should be launched as soon as possible. This along with the previous requirement should preclude simple Future polling + Thread.sleep(). As a bonus, I would like to dataflow engine itself to perform some action (like logging) every time task is finished or when no has finished in X time since last task has finished. Something like: ExecutorCompletionService<T> ecs; while (hasTasks()) { Future<T> future = ecs.poll(1 minute); some_action_like_logging(); if (future != null) { future.get() ... } ... } Are there straightforward ways to do all this with Java concurrency API? Or if it's going to complex no matter what with what's available in the JDK, is there a lightweight library that satisfies the requirements? I already have a partial solution that fits my particular use case (it cheats in a way, since I'm using two executors, and just so you know, it's not related at all to the web browser example I gave above), but I'd like to see a more general purpose and elegant solution.
