  • Maven - Include dependent libs in jar without unpacking dependencies?

    - by Marcus
    We're trying to build a client jar that includes unpacked depenedent jar's. And the manifest should have class-path entries to the dependent jars. The snippet below works but the jars are unpacked - how can we stop the jars from being unpacked? <plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> <archive> <manifest> <addClasspath>true</addClasspath> </manifest> </archive> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin>

  • What is the standard way to bundle OSGi dependent libraries?

    - by Chris
    Hi, I have a project that references a number of open source libraries, some new, some not so new. That said, they are all stable and I wish to stick with my chosen versions until I have time to migrate to the newer versions (I tested hsqldb 2.0 yesterday and it contains many api changes). One of the libraries I have wish to embed is Jasper Reports, but as you all surely know, it comes with a mountain of supporting jar files and I have only need a subset of the mountain (known) therefore I am planning to custom bundle all of my dependant libraries. So: Does everyone custom-make their own OSGi bundles for open-source libraries they are using or is there a master source of OSGi versions of common libraries? Also, I was thinking that it would be far simpler for each of my bundles simply to embed their dependent jars within the bundle itself. Is this possible? If I choose to embed the 3rd party foc libraries within a bundle, I assume I will need to produce 2 jar files, one without the embedded libraries (for libraries to be loaded via the classpath via standard classloader), and one osgi version that includes the embedded libraryy, therefore should I choose a bundle name like this <<myprojectname>>-<<subproject>>-osgi-.1.0.0.jar ? If I cannot embed the open source libraries and choose to custom bundle the open source libraries (via bnd), should I choose a unique bundle name to avoid conflict with a possible official bundle? e.g. <<myprojectname>>-<<3rdpartylibname>>-<<3rdpartylibversion>>.jar ? My non-OSGi enabled project currently scans for custom plugins via scanning the META-INF folders in my various plugin jars via Service.providers(...). If I go OSGi, will this mechanism still work?

  • How to make the cursor shape dependent on the current Vim mode using iTerm2 on OS X and zsh

    - by i0n
    I am using zsh and iTerm2 to edit with Vim. I really love the integration and portability, and because of that I have chosen not to use MacVim. But.... I can't work out how to get my cursor to change from a block to a line when in Vim's insert mode. I've been lead to believe that it's not possible by standard means, but people seem to think that it is possible using zsh. I've done as much Google searching as I can take without an answer, any help or advice would be greatly appreciated.

  • Lazy loading the addthis script? (or lazy loading external js content dependent on already fired eve

    - by Keith Bentrup
    I want to have the addthis widget available for my users, but I want to lazy load it so that my page loads as quickly as possible. However, after trying it via a script tag and then via my lazy loading method, it appears to only work via the script tag. In the obfuscated code, I see something that looks like it's dependent on the DOMContentLoaded event (at least for firefox). Since the DOMContentLoaded event has already fired, the widget doesn't render properly. What to do? I could just use a script tag (slower)... or could I fire (in a cross browser way) the DOMContentLoaded (or equivalent) event? I have a feeling this may not be possible b/c I believe that (like jQuery) there are multiple tests of the content ready event, and so multiple simulated events would have to occur. Nonetheless, this is an interesting problem b/c I have seen a couple widgets now assume that you are including their stuff via static script tags. It would be nice if they wrote code that was more useful to developers concerned about speed, but until then, is there a work around?? And/or are any of my assumptions wrong? Edit: Because the 1st answer to the question seemed to miss the point of my problem, I wanted to clarify the situation. This is about a specific problem. I'm not looking for yet another lazy load script or check if some dependencies are loaded script. Specifically this problem deals with external widgets that you do not have control over and may or may not be obfuscated delaying the load of the external widgets until they are needed or at least, til substantially after everything else has been loaded including other deferred elements b/c of the how the widget was written, precludes existing, typical lazy loading paradigms While it's esoteric, I have seen it happen with a couple widgets - where the widget developers assume that you're just willing to throw in another script tag at the bottom of the page. I'm looking to save those 500-1000 ms** though as numerous studies by yahoo, google, and amazon show it to be important to your user's experience. **My testing with hammerhead and personal experience indicates that this will be my savings in this case.

  • jQuery Datatables throws error when dynamically created row headers

    - by JM4
    I am using the Datatables jquery plugin for one of my projects. For one in particular, the number of columns can vary based on how many children a consumer has (yes I realize normalization and proper technique would insert on another row but it is a client requirement). Datatables must be set up as such: <table> <thead> <tr> <th></th> </tr> </thead> <tbody> <tr> <td></td> </tr> </tbody> </table> my script starts out as: <table cellpadding="0" cellspacing="0" border="0" class="display" id="sortable"> <thead> <tr> <th>parent name</th> <th>parent phone</th> <?php try { $db->beginTransaction(); $stmt = $db->prepare("SELECT max(num_deps) FROM (SELECT count(a.id) as num_deps FROM children a INNER JOIN parents b USING(id) WHERE a.id !=0 GROUP BY a.id) x"); $stmt->execute(); $rows = $stmt->fetchAll(); for($i=1; $i<=$rows[0][0]; $i++) { echo " <th>Child Name ".$i."</th> <th>Date of Birth ".$i."</th> "; } $db->commit(); } catch (PDOException $e) { echo "<p align='center'>There was a system error. Please contact administration.<br>".$e->getMessage()."</p><br />"; } ?> </tr> </thead> In this manner, the final column headers can be 1 or 50 spots long. However, with this dynamic code in place, datatables throws the following error: ""DataTables warning (table id = 'datatable'): Cannot reinitialise DataTable. To retrieve the DataTables object for this table, please pass either no arguments to the dataTable() function, or set bRetrive to true. Alternativly, to destroy old table and create a new one...ETC."' Yes I have set "bRetrieve" : true in the javascript above and that does not do the trick. If I remove the code above, the file "works" fine but it leaves off the necessary columns for my table. Any ideas?

  • How to make radio button options dependent on other radio button choices using Mootools?

    - by Mike Crittenden
    I have a form where there are 6 items, each of which can be ranked from 1-6 in order of importance. Here's a screenshot. Basically, I need to set it up so that if one item gets a ranking of 3 (for example), then "3" becomes disabled for all the other items. Therefore, the user should only be able to select a number that hasn't already been selected for each item (so we can ensure that the items really will be ranked 1-6 and no numbers will be repeated for different items). Here's the markup I'm working with (minus the presentational divs): <label for="importantProductQuality">Product Quality</label> <input id="importantProductQuality_0" name="importantProductQuality"

  • Flex: Double click event propagation on datagrid dependent on component order?

    - by MyMacAndMe
    I'd like to have a double click event on a datagrid in Flex3. The following example only works if the Accordion (id = "mustBeSecond") container comes after the DataGrid. Why is the order of the components important and what can I do to prevent this behavior? (The example does not work. If you change the order of "mustBeSecond" and "gridReportConversions" the example works fine) <mx:Script> <![CDATA[ import mx.controls.Alert; import mx.collections.ArrayCollection; [Bindable] private var dp:ArrayCollection = new ArrayCollection([ {qty:1,referer:'http://google.com'}, {qty:25,referer:'http://cnn.com'}, {qty:4,referer:'http:stackoverflow.com'}]); private function refererRowDoubleClicked(e:Event):void { Alert.show("double click"); } ]]> </mx:Script> <mx:HBox width="100%" height="100%"> <mx:Accordion width="200" height="200" id="mustBeSecond"> <mx:Canvas label="Navigation Box" width="100%" height="100%"> <mx:VBox> <mx:LinkButton label="First Link" /> <mx:LinkButton label="Second Link" /> </mx:VBox> </mx:Canvas> </mx:Accordion> <mx:DataGrid id="gridReportConversions" height="100%" width="100%" dataProvider="{this.dp}" mouseEnabled="true" doubleClickEnabled="true" itemDoubleClick="refererRowDoubleClicked(event)"> <mx:columns> <mx:DataGridColumn width="75" dataField="qty" headerText="Qty" /> <mx:DataGridColumn dataField="referer" headerText="URL" /> </mx:columns> </mx:DataGrid> </mx:HBox>

  • How can I find installed programs dependent on any version of the .NET framework?

    - by Russ
    I have an application that uses .NET 3.5SP1, but I have been having a LOT of random crashes with it. I am starting to narrow the fields of possible causes to the framework itself, where I suspect some other app is installing a lower patch version. Is there any apps in the wild, or anything I can slap together that can tell me what apps that are installed that depend on .NET to run? Their minimum required version would be nice to know also, but not necessary.

  • SQL Is it possible to setup a column that will contain a value dependent on another column?

    - by Wesley
    I have a table (A) that lists all bundles created off a machine in a day. It lists the date created and the weight of the bundle. I have an ID column, a date column, and a weight column. I also have a table (B) that holds the details related to that machine for the day. In that table (B), I want a column that lists a sum of weights from the other table (A) that the dates match on. So if the machine runs 30 bundles in a day, I'll have 30 rows in table (A) all dated the same day. In table (B) I'll have 1 row detailing other information about the machine for the day plus the column that holds the total bundle weight created for the day. Is there a way to make the total column in table (B) automatically adjust itself whenever a row is added to table (A)? Is this possible to do in the table schema itself rather than in an SQL statement each time a bundle is added? If it's not, what sort of SQL statement do I need? Wes

  • Calculus? Need help solving for a time-dependent variable given some other variables.

    - by user451527
    Long story short, I'm making a platform game. I'm not old enough to have taken Calculus yet, so I know not of derivatives or integrals, but I know of them. The desired behavior is for my character to automagically jump when there is a block to either side of him that is above the one he's standing on; for instance, stairs. This way the player can just hold left / right to climb stairs, instead of having to spam the jump key too. The issue is with the way I've implemented jumping; I've decided to go mario-style, and allow the player to hold 'jump' longer to jump higher. To do so, I have a 'jump' variable which is added to the player's Y velocity. The jump variable increases to a set value when the 'jump' key is pressed, and decreases very quickly once the 'jump' key is released, but decreases less quickly so long as you hold the 'jump' key down, thus providing continuous acceleration up as long as you hold 'jump.' This also makes for a nice, flowing jump, rather than a visually jarring, abrupt acceleration. So, in order to account for variable stair height, I want to be able to calculate exactly what value the 'jump' variable should get in order to jump exactly to the height of the stair; preferably no more, no less, though slightly more is permissible. This way the character can jump up steep or shallow flights of stairs without it looking weird or being slow. There are essentially 5 variables in play: h -the height the character needs to jump to reach the stair top<br> j -the jump acceleration variable<br> v -the vertical velocity of the character<br> p -the vertical position of the character<br> d -initial vertical position of the player minus final position<br> Each timestep:<br> j -= 1.5; //the jump variable's deceleration<br> v -= j; //the jump value's influence on vertical speed<br> v *= 0.95; //friction on the vertical speed<br> v += 1; //gravity<br> p += v; //add the vertical speed to the vertical position<br> v-initial is known to be zero<br> v-final is known to be zero<br> p-initial is known<br> p-final is known<br> d is known to be p-initial minus p-final<br> j-final is known to be zero<br> j-initial is unknown<br> Given all of these facts, how can I make an equation that will solve for j? tl;dr How do I Calculus? Much thanks to anyone who's made it this far and decides to plow through this problem.

  • How can I make one Code::Blocks project dependent on another?

    - by George Edison
    I have a workspace with two projects in it. One is a static library (we'll call it Project A). The other is a console app that links with the static library (we'll call it Project B). I went to Project B's properties and checked off Project A as a dependency of Project B. So I make a change to a file in Project A and rebuild Project B. It correctly discovers the changes to the file in Project A and rebuilds Project A. However, when it gets to Project B it says: Target is up to date. Nothing to be done. How can I tell it to run the linker everytime Project A is changed?

  • Correct way to (re)launch a Java application with hardware-dependent VM parameters?

    - by LowLevelAbstraction
    EDIT I don't want to use Java Web Start I've got a Java application that I'd like to run with different VM parameters depending on the amount of memory the system it is launched on has. For example if the machine has 1 GB of memory or less I'd like to pass "-Xmx200m" and "-Xmx400m" if it has 2 GB and "-Xmx800m" if it has 8 GB (these are just examples). Is there a portable way to do this? I've tried having a first tiny Java app (hence portable) that determines the amount of memory available and then launches a new Java app but I don't think this is very clean. As of now I've written Bash shell scripts that invoke the Java app with the correct parameters depending on the config but it only works on Linux on OS X. What is the correct way to solve this? Would application packager package ;) help ?

  • Using perl's Regexp::Grammars, how do I make a capture dependent on $MATCH?

    - by Evan Carroll
    I've got a token like such: <delim2=((?{ $MATCH{delim} }))> and what I want to happen is for delim2 to capture and be set to the value of delim. When I run this, delim2 is set, but the capture is never done. I think this is an error in my reasoning: I'm trying to chain this form: <ALIAS= ( PATTERN )> Match pattern, save match in $MATCH{ALIAS} and this form: (?{ MATCH{delim} }) into something like this <ALIAS= ( (?{MATCH{delim}) )> Matches the value of $MATCH{delim} save to $MATCH{delim2} but this simply doesn't seem valid. I can verify my original token works <delim2=((?{ die $MATCH{delim} }))> will die with the value, and, if I hard code it, I get the right capture and everything works <delim2=(')>? So how do I go about achieving sane results, while having a dynamic pattern?

  • In Visual Studio (2008) is there a way to have a custom dependent file on another custom file?

    - by rball
    Instead of a *.cs code behind or beside I'd like to have a *.js file. I'm developing a MVC application an have no need for a code beside because I have controllers, but in certain cases it'd be nice to have a JavaScript code beside or some way to associate the file to the page it's being used on. I suppose I could just name them similarly, but I'm wanting to show the association if possible so there's no question about what the file is for. Typically what I'm talking about is within Visual Studio now under your Global.asax file you will have a plus sign to the left: + Global.asax Once you expand it you'll get - Global.asax Global.asax.cs I'd like the same thing to happen: + Home.spark - Home.spark Home.spark.js Updated: My existing csproj file has a path to the actual file, not sure if that's screwing it up. I've currently got: <ItemGroup> <Content Include="Views\User\Profile.spark.js"> <DependentUpon>Views\User\Profile.spark</DependentUpon> </Content> </ItemGroup> <ItemGroup> <Content Include="Views\User\Profile.spark" /> </ItemGroup> and it's simply just showing the files besides each other.

  • Ways to update a dependent table in the same MySQL transaction?

    - by codie
    I need to update two tables inside a single transaction. The individual queries look something like this: 1. INSERT INTO t1 (col1, col2) VALUES (val1, val2) ON DUPLICATE KEY UPDATE col2 = val2; If the above query causes an insert then I need to run the following statement on the second table: 2. INSERT INTO t2 (col1, col2) VALUES (val1, val2) ON DUPLICATE KEY UPDATE col2 = col2 + val2; otherwise, 3. UPDATE t2 SET col2 = col2 - old_val2 + val2 WHERE col1 = val1; -- old_val2 is the value of t1.col2 before it was updated Right now I run a SELECT on t1 first, to determine whether statement 1 will cause an insert or update on t1. Then I run statement 1 and either of 2 and 3 inside a transaction. What are the ways in which I can do all of these inside one transaction itself? The approach I was thinking of is the following: UPDATE t2, t1 set t2.col2 = t2.col2 - t1.col2 WHERE t1.col1 = t2.col2 and t1.col1 = val1; INSERT INTO t1 (col1, col2) VALUES (val1, val2) ON DUPLICATE KEY UPDATE col2 = val2; INSERT INTO t2, t1 (t2.col1, t2.col2) VALUES (t1.col1, t1.col2) ON DUPLICATE KEY UPDATE t2.col2 = t2.col2 + t1.col2 WHERE t1.col1 = t2.col2 and t1.col1 = val1; Unfortunately, there's no multi-table INSERT... ON DUPLICATE KEY UPDATE in MySQL 5.0. What else could I do?

    I'm trying to implement an assets/dependency loader that i've found from an old article at 24Ways.org. most of you might be familiar with it. it's from this article by Christian Heilmann: http://24ways.org/2007/keeping-javascript-dependencies-at-bay i've modified the script to load CSS files as well. and it's now quite close to what i want. but i still need to do some checking to see wether an asset have been completely loaded or not. just wondering if you guys have any ideas :) here's what my script currently looked like: var assetLoader = { assets: { products: { js: 'products.js', css: 'products.css', loaded: false }, articles: { js: 'articles.js', css: 'articles.css', loaded: false }, [...] cycle: { js: 'jquery.cycle.min.js', loaded: false }, swfobject: { js: 'jquery.swfobject.min.js', loaded: false } }, add: function(asset) { var comp = assetLoader.assets[asset]; var path = '/path/to/assets/'; if (comp && comp.loaded == false) { if (comp.js) { // load js var js = document.createElement('script'); js.src = path + 'js/' + comp.js; js.type = 'text/javascript'; js.charset = 'utf-8'; // append to document document.getElementsByTagName('body')[0].appendChild(js); } if (comp.css) { // load css var css = document.createElement('link'); css.rel = 'stylesheet'; css.href = path + 'css/' + comp.css; css.type = 'text/css'; css.media = 'screen, projection'; css.charset = 'utf-8'; // append to document document.getElementsByTagName('head')[0].appendChild(css); } } }, check: function(asset) { assetLoader.assets[asset].loaded = true; } } Christian explains this method in his article in great detail. I don't want to confuse you guys anymore with my bad english :P and here's an example of how i run the script: ... // load jquery cycle plugin if (page=='tvc' || page=='products') { if (!assetLoader.assets.cycle.loaded) { assetLoader.add('cycle'); } } // load products page assets if (!assetLoader.assets.products.loaded) { assetLoader.add('products'); } ... this kind of approach is very problematic though. coz assets loads asynchronously, which means some of the code inside products.js that depends on jquery.cycle.js might continue running before jquery.cycle.js is even loaded resulting in errors. while i'm quite aware that scripts can be attached with an onload event, i'm just not really sure how to implement it to my script. anyone care to help me? please... :P

  • Does .Net use Device Dependent or Device Independent Bitmaps?

    - by Brian
    When loading an image into memory, does .Net use DDB, DIB, or something else entirely? If possible, please cite your sources. I'm wondering because we currently have a classic ASP application that is using a 3rd party component to load images that is occasionally creating a “Not enough storage is available to process this command.” error. The error is very inconsistent but tends to happen on larger images (not always, but often). After resetting IIS, processing the same file again typically works just fine. After much research I have found that DDBs tend to have this problem when processing large images because they work out of video memory. Considering that we are running on a web server with an integrated video card and limited shared memory, this could certainly be our problem. We are in the early stages of converting our app to .Net and am wondering if using .Net for this might be a viable alternative to our current method which is why I am asking the question. Any advice is welcome :) but out of curiosity if nothing else, I am really hoping for an answer to the question; does .Net use DDB or DIB?

  • How do I do a count on that meet a specific condition, dependent on several has_many relationships i

    - by Angela
    I have a Model Campaign. A Campaign has many Events. Each Event has an attribute :days. A Campaign also has_many Contacts. Each Contact as a :date_entered attribute. The from_today(contact,event) method returns a number, which is the number of days from the contact's :date_entered till today minus the event's :days. In other words, a positive number shows the number of days from today till the :days of the event is elapsed. If it is negative, if means that the number of days that has elapsed since the :date_entered is greater than the :days attribute of an event. In other words, the event is overdue. What I would like to be able to do is do campaign.overdue and this would result in a total number of contacts that have an overdue event. It shouldn't count multiple events for a single contact, just one contact. How do I do that? It seems like I would need to cycle through all the events for every contact and keep a counter but I'm assuming that there is a better way.

  • How do you make a WiX project build when dependent files have changes?

    - by Scott Langham
    Hi, I've adopted a Visual Studio solution that contains a number WiX projects. We build the solution from an MsBuild script to generate the product's installer msi. The problem I'm experiencing is that if I build (and don't rebuild), even if exe's and dll's get updated that need to be put in the installer, the WiX build system doesn't seem to detect this and skips building the installer as it thinks it's already up to date. How do I work out what the dependencies are that are needed to build a WiX project, and how do I tell the Wix build system to watch out for them changing so it knows to build instead of skip?

  • How to launch a dependent application on OS X?

    - by jldupont
    What is the programmatical mechanism by which an application can be launched at a result of another one being launched? E.g. upon launching iTunes, the Last.fm desktop launches too. Or it is just a question of substituting a "batch file" of some sort? Note: OS X newbie.

  • Name lookup for names not dependent on template parameter in VC++2008 Express. Is it a bug?

    - by Maciej H
    While experimenting a bit with C++ templates I managed to produce this simple code, for which the output is different, than I expected according to my understanding of C++ rules. void bar(double d) { std::cout << "bar(double) function called" << std::endl; } template <typename T> void foo(T t) { bar(3); } void bar(int i) { std::cout << "bar(int) function called" << std::endl; } int main() { foo(3); return 0; } When I compile this code is VC++2008 Express function bar(int) gets called. That would be the behaviour I would expect if bar(3);in the template body was dependent on the template parameter. But it's not. The rule I found here says "The C++ standard prescribes that all names that are not dependent on template parameters are bound to their present definitions when parsing a template function or class". Am I wrong, that "present definition" of bar when parsing the template function foo is the definition of void bar(double d);? Why it's not the case if I am wrong. There are no forward declarations of bar in this compilation unit.
