  • .Net xsd.exe tool doesn't generate all types

    - by Mrchief
    For some reason, MS .Net (v3.5) tool - xsd.exe doesn't generate types when they are not used inside any element. e.g. XSD File (I threw in the complex element to avoid this warning - "Warning: cannot generate classes because no top-level elements with complex type were found."): <?xml version="1.0" encoding="utf-8"?> <xs:schema targetNamespace="http://tempuri.org/XMLSchema.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema.xsd" xmlns:mstns="http://tempuri.org/XMLSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" > <xs:simpleType name="EnumTest"> <xs:restriction base="xs:string"> <xs:enumeration value="item1" /> <xs:enumeration value="item2" /> <xs:enumeration value="item3" /> </xs:restriction> </xs:simpleType> <xs:complexType name="myComplexType"> <xs:attribute name="Name" use="required" type="xs:string"/> </xs:complexType> <xs:element name="myElem" type="myComplexType"></xs:element> </xs:schema> When i run this thru xsd.exe using xsd /c xsdfile.xsd I don't see EnumTest in the generated cs file. Note; Even though I don't use the enum here, but in my actual project, I have cases like this where we send enum's string value as output. How can I force the xsd tool to include these? Or should I switch to some other tool? I work in Visual Studio 2008.

  • Loading a class file immediately AFTER startup

    - by Striker
    We have a few war files deployed inside an ear file. Some of the war files have a class that caches static data from our PLM system in singletons. Since some of the classes take several minutes to load we use the load-on-startup in the web.xml to load them ahead of time. This all works fine until we attempt to re-deploy the application on our production servers. (WebLogic 10.3) We get an exception from our PLM API about a dll already being loaded. Our PLM vendor has confirmed that this is a problem and stated that they don't support using the load-on-startup. This is also a huge problem on our development boxes where we have redeploy the app all the time. Most of us, when we're not working on one of the apps that uses a cache, have them commented out. Obviously we can't do that for the production servers. Right now we transfer the ear to the production server, deploy it in the console, wait for it to crash, shut the app server instance down and then start it up again. We need to find a way around this... One suggestion was to create a servlet that we can call after the server boots that will load the various caches. While this will work I'm looking for something a bit cleaner. Is there anyway to detect once the server started and then fire off the methods? Thanks.

  • Get notified when objective-c dom updates are ready initiated from webview

    - by Josh
    I am programmatically updating the DOM on a WebKit webview via DOMElement objects - for complex UI, there is usually a javascript component to any element that I add. This begs the need to be notified when the updates complete -- is there any such event? I know regular divs dont fire an onload or onready event, correct? The other assumption I had, which may be totally wrong, is that DOMElement updates aren't synchronous, so I can't do something like this and be confident it will meet with the label actually in the DOM: DOMElement *displayNameLabel = [document createElement:@"div"]; [displayNameLabel setAttribute:@"class" value:@"user-display-name"]; [displayNameLabel setTextContent:currentAvatar.avatarData.displayName]; [[document getElementById:@"user-card-content"] appendChild:displayNameLabel]; id win = [webView windowScriptObject]; [win evaluateWebScript:@"javascriptInstantiateLabel()"]; Is this true? I am using jquery within the body of the html already, so I don't mind subscribing to a particular classes set of events via "live." I thought I might be able to do something like: $(".some-class-to-be-added-later").live( "ready", function(){ // Instantiate some fantastic javascript here for .some-class }); but have experienced no joy so far. Is there any way on either side (objective-c since I don't programmatically firing javascript post load, or javascript) to be notified when the element is in the DOM? Thanks, Josh

  • Continuous Integration with 64-bit Sharepoint and TFS 2008?

    - by Hirvox
    I've set up a 64-bit TFS 2008 build server with Sharepoint, continuous integration and out-of-the-box MSTest. Unit tests for plain business logic classes run just fine and test results are published into TFS. However, any test that uses Sharepoint's API fails horribly, SPFarm.Local returning null and so on. Is there a way to fix this? The tests run fine in an otherwise identical 32-bit development environment (Windows Server 2008 under Hyper-V, Sharepoint patched up to June 2009 cumulative update) from both Visual Studio and command line, so the problem is not about improper use of SPContext.Current or any other part of the API that needs to be run in a web server context. I've ruled out permissions issues, because the build agent account can deploy the solution and create site collections just fine with stsadm. The next culprit could be that the unit tests were being run with a 32-bit process, which couldn't access the 64-bit Sharepoint API properly. I tried a workaround, but it has the side effect of disabling TFS support in MSTest. Do I have to wait for 2010 versions of MS tools (and hope for the best) or is there a third-party test framework available that runs natively in 64 bit and can publish test results into TFS 2008?

  • How to tell axis2 to use an existing object as a service?

    - by Christian Hausknecht
    I am trying to expose some methods of a running application as a webservice. The core idea is to use an embedded web-server and send the soap messages to the apache axis2 framework in order to invoke the services. The problem is, that axis2's createService methods only accept Classes as parameter, not existing objects. So I believe that axis2 itself creates an object of the service class and then uses it to call methods when an external service call arrives. But I need to pass an existing object for being used as a service, because I need to call methods of other objects of the running application within the service methods. So the "standard" way that axis2 creates a new instance of the service class and calls then its methods is obviously no sulution for me. So is there a way to realize this? Or is there another solution? Perhaps you can pass objects later on to the allready created service object by axis2? If there is another solution without axis2 I might consider that one. Basically I am only interested in exposing some functionality of a runnning application as a webservice.

  • Using T4MVC in real project

    - by artvolk
    T4MVC is cool, but I have a couple of issues integrating it in my project, any help is really appriciated: I've got such warnings for all my actions (I use SnippetsBaseController as base class for all my controller classes: Warning 26 'Snippets.Controllers.ErrorController.Actions' hides inherited member 'Snippets.Controllers.Base.SnippetsBaseController.Actions'. Use the new keyword if hiding was intended. C:\projects_crisp-source_crisp\crisp-snippets\Snippets\T4MVC.cs 481 32 Snippets Is it possible to have strongly typed names of custom Routes, for example, I have route defined like this: routes.MapRoute( "Feed", "feed/", MVC.Snippets.Rss(), new { controller = "Snippets", action = "Rss" } ); Is it possible to replace: <%= Url.RouteUrl("Feed") %> with something like: <%= Url.RouteUrl(MVC.Routes.Feed) %> Having strongly typed links to static files is really cool, but I use <base /> in my pages, so I don't need any URL processing, can I redefine T4MVCHelpers.ProcessVirtualPath without tweaking the T4MVC.tt itself? T4MVC always generate links with uppercased controller and action names, for example: /Snippets/Add instead of /snippets/add. Is it possible to generate them lowercase?

  • Dependency Injection for objects that require parameters

    - by Andrew
    All of our reports are created from object graphs that are translated from our domain objects. To enable this, we have a Translator class for each report, and have been using Dependency Injection for passing in dependencies. This worked great, and would yield nice classes structured like this: public class CheckTranslator : ICheckTranslator { public CheckTranslator (IEmployeeService empSvc , IPaycheckService paySvc) { _empSvc = empSvc; _paySvc = paySvc; } public Check CreateCheck() { //do the translation... } } However, in some cases the mapping has many different grouping options. As a result, the c-tor would turn into a mix of class dependencies and parameters. public class CheckTranslator : ICheckTranslator { public CheckTranslator (IEmployeeService empSvc , IPaycheckService paySvc , bool doTranslateStubData , bool doAttachLogo) { _empSvc = empSvc; _paySvc = paySvc; _doTranslateStubData = doTranslateStubData; _doAttachLogo = doAttachLogo; } public Check CreateCheck() { //do the translation... } } Now, we can still test it, but it no longer really works with an IoC container, at least in a clean fashion. Plus, we can no longer call the CreateCheck twice if the settings are different for each check. While I recognize it's a problem, I don't necessarily see the right solution. It seems kind of strange to create a Factory for each class ... or is this the best way?

  • How to access a superclass's class attributes in Python?

    - by Brecht Machiels
    Have a look at the following code: class A(object): defaults = {'a': 1} def __getattr__(self, name): print('A.__getattr__') return self.get_default(name) @classmethod def get_default(cls, name): # some debug output print('A.get_default({}) - {}'.format(name, cls)) try: print(super(cls, cls).defaults) # as expected except AttributeError: #except for the base object class, of course pass # the actual function body try: return cls.defaults[name] except KeyError: return super(cls, cls).get_default(name) # infinite recursion #return cls.__mro__[1].get_default(name) # this works, though class B(A): defaults = {'b': 2} class C(B): defaults = {'c': 3} c = C() print('c.a =', c.a) I have a hierarchy of classes each with its own dictionary containing some default values. If an instance of a class doesn't have a particular attribute, a default value for it should be returned instead. If no default value for the attribute is contained in the current class's defaults dictionary, the superclass's defaults dictionary should be searched. I'm trying to implement this using the recursive class method get_default. The program gets stuck in an infinite recursion, unfortunately. My understanding of super() is obviously lacking. By accessing __mro__, I can get it to work properly though, but I'm not sure this is a proper solution. I have the feeling the answer is somewhere in this article, but I haven't been able to find it yet. Perhaps I need to resort to using a metaclass?

  • Need some help to determine the amount of recursive calls in PHP

    - by Ben Fransen
    Hi all, I've got a, I think fairly easy question, but this is bugging me for a while now. So I figured, maybe I can get some help here. Since recursive functions are always a bit tricky, and sometimes a bit unclear to me, I keep struggling to create a nice working solution to get my menudata. In one of my classes I have this function, which gives me all menu-items recursivly. The thing I want is to determine at which recursionlevel a certain object was retrieved so I can create a nicely looking HTML output with indents for the levels of nesting. public function GetObjectList($parentID = 0, $objectlist = null) { if(is_null($objectlist)) { $objectlist = new ObjectList("Model_Navigation"); } $query = MySQL::Query("SELECT * FROM `Navigation` WHERE `WebsiteID` = ".SITE_ID. " AND `LanguageID` = ".LANG_ID." AND `ParentID` = ".$parentID); while($result = MySQL::FetchAssoc($query)) { $object = new Model_Navigation(); $object->ID = $result["ID"]; $object->WebsiteID = $result["WebsiteID"]; $object->LanguageID = $result["LanguageID"]; $object->ParentID = $result["ParentID"]; $object->Name = $result["Name"]; $object->Page = Model_Page::GetObjectByID($result["PageID"]); $object->ExternalURL = $result["ExternalURL"]; $object->Index = $result["Index"]; $object->Level = [here lies my problem]; $objectlist->Add($object); self::GetObjectList($object->ID, $objectlist); } return $objectlist; } Hope to hear from you! Greetings from Holland, Ben Fransen

  • Installing RestEasy documentation is not clear--does maven install resteasy?

    - by user798719
    3.1. Standalone Resteasy If you are using resteasy outside of JBoss AS 6, you will need to do a few manual steps to install and configure resteasy. RESTeasy is deployed as a WAR archive and thus depends on a Servlet container. We strongly suggest that you use Maven to build your WAR files as RESTEasy is split into a bunch of different modules. You can see an example Maven project in one of the examples in the examples/ directory Also, when you download RESTeasy and unzip it you will see a lib/ directory that contains the libraries needed by resteasy. Copy these into your /WEB-INF/lib directory. Place your JAX-RS annotated class resources and providers within one or more jars within /WEB-INF/lib or your raw class files within /WEB-INF/classes. Hi, is my confusion justified? I am using JBoss 5 unfortunately. Do I need to download RESTeasy and unzip it IF I am using Maven, as the documentation recommends? Maven grabs all the dependencies that are needed to build a project, including the RESTEasy fraemwork, right? So why the contradiction here? Wish that the documentation would anticipate common questions and be written more clearly.

  • Disassembler that tracks what value is where

    - by Martin C. Martin
    So lately I've been looking at the disassembly of my C++ code, and having to manually track what's in each register, like this: 95: 48 8b 16 mov (%rsi),%rdx ; %rdx = raggedCross.sink 98: 48 8b 42 38 mov 0x38(%rdx),%rax ; %rax = sink.table 9c: 8b 4a 10 mov 0x10(%rdx),%ecx ; %ecx = sink.baseCol 9f: 48 8b 70 50 mov 0x50(%rax),%rsi ; %rsi = table.starts a3: 89 c8 mov %ecx,%eax ; %eax = baseCol a5: 83 c1 1c add $0x1c,%ecx ; %ecx = baseCol + 1 And so on. The comments are mine, added by hand, from looking up the offset of various fields (e.g. sink, table, baseCol, starts) in the C++ classes. It's straight forward to do, but tedius and time consuming: the perfect thing for a program to be doing. gdb seems to know the offset of various fields within a struct: I can do &((Table *)0x1200)-starts and it tells the the right address. So, this information is around. Is there some disassembler that can use this info to annotate the code for me? Failing that, I could write my own. Where does gdb get the offsets?

  • Web API Getting Http 500 error : Issue Solved See Below

    - by Joe Grasso
    Here is my MVC Controller and everything is fine: private UnitOfWork UOW; public InventoryController() { UOW = new UnitOfWork(); } // GET: /Inventory/ public ActionResult Index() { var products = UOW.ProductRepository.GetAll().ToList(); return View(products); } Same method call in API Controller gives me an Http 500 Error: private UnitOfWork _unitOfWork; public TestController() { _unitOfWork = new UnitOfWork(); } public IEnumerable<Product> Get() { var products = _unitOfWork.ProductRepository.GetAll().ToList(); return products; } Debugging shows that indeed there is data being returned in both controllers' UOW calls. I then added a customer configuration in Global: public static void CustomizeConfig(HttpConfiguration config) { config.Formatters.Remove(config.Formatters.XmlFormatter); var json = config.Formatters.JsonFormatter; json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); } I am still receiving an Http 500 in API Controller ONLY and at a loss as to why. Any ideas? UPDATE: It appears using lazy loading caused the problem. When I set the associated properties to NON-VIRTUAL the Test API provided the necessary JSON string. However, whereas before I had the Vendor class included, I only have VendorId. I really wanted to included the associated classes. Any ideas? I know there are alot of smart people out there. Anyone?

  • How to develop JSP/Servlets Web App using MVC pattern?

    - by A.S al-shammari
    I'm developing a JSP/Servlets web app (no frameworks). I want to use MVC pattern. I designed my project like this : Controller :a servlet that reads a request, extracts the values,communicates with model objects and gives information to a JSP page. View : JSP Pages. Model : Java Classes / Java Beans .. etc . The problem : Index.jsp is the starting point (default page) in my web site. So, the Index.jsp becomes the controller to parse the request! .For example , the following request : index.jsp?section=article&id=10 parsed in index.jsp as following : <div class="midcol"> <!-- Which section? --> <%String fileName = request.getParameter("section"); if (fileName == null) { fileName = "WEB-INF/jspf/frontpage.jsp"; } else { fileName = "WEB-INF/jspf/" + fileName + ".jsp"; } %> <jsp:include page='<%= fileName%>' /> </div> Here, I can't force the servlet to be a controller .. because the index.jsp is the controller here since it's the starting point! Is there any solution to forward the request from index.jsp to the servlet and then go back to index.jsp ? Or any solution that achieves the MVC goal - the servlet should be the controller - ? I'm thinking of making a FrontPageController servlet as default page instead of index.jsp ! but I don't know if it's a perfect idea ?!

  • Is it safe to reuse javax.xml.ws.Service objects

    - by Noel Ang
    I have JAX-WS style web service client that was auto-generated with the NetBeans IDE. The generated proxy factory (extends javax.xml.ws.Service) delegates proxy creation to the various Service.getPort methods. The application that I am maintaining instantiates the factory and obtains a proxy each time it calls the targetted service. Creating the new proxy factory instances repeatedly has been shown to be expensive, given that the WSDL documentation supplied to the factory constructor, an HTTP URI, is re-retrieved for each instantiation. We had success in improving the performance by caching the WSDL. But this has ugly maintenance and packaging implications for us. I would like to explore the suitability of caching the proxy factory itself. Is it safe, e.g., can two different client classes, executing on the same JVM and targetting the same web service, safely use the same factory to obtain distinct proxy objects (or a shared, reentrant one)? I've been unable to find guidance from either the JAX-WS specification nor the javax.xml.ws API documentation. The factory-proxy multiplicity is unclear to me. Having Service.getPort rather than Service.createPort does not inspire confidence.

  • python eval weirdness

    - by amadain
    Hi Folks I have the following code in one of my classes along with checks when the code does not eval: filterParam="self.recipientMSISDN==tmpBPSS.split('_')[3].split('#')[0] and self.recipientIMSI==tmpBPSS.split('_')[3].split('#')[1]" if eval(filterParam): print "Evalled" else: print "Not Evalled\nfilterParam\n'%s'\ntmpBPSS\n'%s'\nself.recipientMSISDN\n'%s'\nself.recipientIMSI\n'%s'" % (filterParam, tmpBPSS, self.recipientMSISDN, self.recipientIMSI) I am not getting anything to 'eval'. Here are the results: Not Evalled filterParam 'self.recipientMSISDN==tmpBPSS.split('_')[3].split('#')[0] and self.recipientIMSI==tmpBPSS.split('_')[3].split('#')[1]' tmpBPSS 'bprm_DAILY_MO_919844000039#892000000' self.recipientMSISDN '919844000039' self.recipientIMSI '892000000' So I used the outputs from the above to check the code in a python shell and as you can see the code evalled correctly: >>> filterParam="recipientMSISDN==tmpBPSS.split('_')[3].split('#')[0] and recipientIMSI==tmpBPSS.split('_')[3].split('#')[1]" >>> tmpBPSS='bprm_DAILY_MO_919844000039#892000000' >>> recipientMSISDN='919844000039' >>> recipientIMSI='892000000' >>> if eval(filterParam): ... print "Evalled" ... else: ... print "Not Evalled" ...

  • Java: Initializing a public static field in superclass that needs a different value in every subclas

    - by BinaryMuse
    Good evening, I am developing a set of Java classes so that a container class Box contains a List of a contained class Widget. A Widget needs to be able to specify relationships with other Widgets. I figured a good way to do this would be to do something like this: public abstract class Widget { public static class WidgetID { // implementation stolen from Google's GWT private static int nextHashCode; private final int index; public WidgetID() { index = ++nextHashCode; } public final int hashCode() { return index; } } public abstract WidgetID getWidgetID(); } so sublcasses of Widget could: public class BlueWidget extends Widget { public static final WidgetID WIDGETID = new WidgetID(); @Override public WidgetID getWidgetID() { return WIDGETID; } } Now, BlueWidget can do getBox().addWidgetRelationship(RelationshipTypes.SomeType, RedWidget.WIDGETID, and Box can iterate through it's list comparing the second parameter to iter.next().getWidgetID(). Now, all this works great so far. What I'm trying to do is keep from having to declare the public static final WidgetID WIDGETID in all the subclasses and implement it instead in the parent Widget class. The problem is, if I move that line of code into Widget, then every instance of a subclass of Widget appears to get the same static final WidgetID for their Subclassname.WIDGETID. However, making it non-static means I can no longer even call Subclassname.WIDGETID. So: how do I create a static WidgetID in the parent Widget class while ensuring it is different for every instance of Widget and subclasses of Widget? Or am I using the wrong tool for the job here? Thanks!

  • What's your most controversial programming opinion?

    - by Jon Skeet
    This is definitely subjective, but I'd like to try to avoid it becoming argumentative. I think it could be an interesting question if people treat it appropriately. The idea for this question came from the comment thread from my answer to the "What are five things you hate about your favorite language?" question. I contended that classes in C# should be sealed by default - I won't put my reasoning in the question, but I might write a fuller explanation as an answer to this question. I was surprised at the heat of the discussion in the comments (25 comments currently). So, what contentious opinions do you hold? I'd rather avoid the kind of thing which ends up being pretty religious with relatively little basis (e.g. brace placing) but examples might include things like "unit testing isn't actually terribly helpful" or "public fields are okay really". The important thing (to me, anyway) is that you've got reasons behind your opinions. Please present your opinion and reasoning - I would encourage people to vote for opinions which are well-argued and interesting, whether or not you happen to agree with them.

  • Pass Variable to Java Method from an Ant Target

    - by user200317
    At the moment I have a .properties file to store settings related to the framework. Example: default.auth.url=http://someserver-at008:8080/ default.screenshots=false default.dumpHTML=false And I have written a class to extract those values and here is the method of that class. public static String getResourceAsStream(String defaultProp) { String defaultPropValue = null; //String keys = null; try { InputStream inputStream = SeleniumDefaultProperties.class.getClassLoader().getResourceAsStream(PROP_FILE); Properties properties = new Properties(); //load the input stream using properties. properties.load(inputStream); defaultPropValue = properties.getProperty(defaultProp); }catch (IOException e) { log.error("Something wrong with .properties file, check the location.", e); } return defaultPropValue; } Throughout the application I use method like follows to just exact property needed, public String getBrowserDefaultCommand() { String bcmd = SeleniumDefaultProperties.getResourceAsStream("default.browser.command"); if(bcmd.equals("")) handleMissingConfigProperties(SeleniumDefaultProperties.getResourceAsStream("default.browser.command")); return bcmd; } But I have not decided do a change to this and use ant and pass a parameter instead of using it from .properties file. I was wondering how could I pass a value to a Java Method using ANT. Non of these classes have Main methods and will not have any main. Due to this I was unable to use it as a java system properties. Thanks in advance.

  • What features do you miss most when switching from IntelliJ to XCode ?

    - by Ori
    Hi, I've started to use XCode several months ago, after using IntelliJ for several years, and there are quite a few features that I really miss. XCode is not that bad, but it is lacking some basic stuff. To trigger the discussion, here are some of the features that I miss most, who knows maybe someone from Apple will bump into this post and steal some Ideas :) Source-level error-highlighting. The write-compile-fix cycle feels like going back in time 15 years ago to my early C days. Many errors can be spotted without having to compile and Java IDEs have been doing it for years. A decent debugger. This is a bit unfair because IntelliJ's debugger is the best I've used so far, but XCode's debugger is at least 5 years behind and Apple has a few more developers than JetBrains... Stronger re-factoring. A no-brainer I guess. XCode has some renaming capabilities (which they call re-factoring), but they are very few. Override method. This one is really amazing. XCode doesn't have an "override method" command which lets you choose the method you want to override from a super class or protocol. You need to go to the documentation or header file and start copy-pasting. Duplicate selected line(s). I've bumped into some posts that offer workarounds for this via custom key-binding, but none of them works, at least for me. Go to last edit point. Bummer! Come on Apple, this one is so easy to implement and so useful! A better open quickly feature. IntelliJ's quick find of classes/files/text is so much better... Turns out that my list goes on and on, so I'll stop here... What other features do you miss most in your transition to XCode?? Ori

  • Can't Compile Correct Mapping File

    - by NoOne
    Hello, Im now developping one application in C# with Remoting objects and NHibernate. So here is a image explaining how my projects are divided. Views Layer This layer will be responsible for the users interface. This layer will always use the Controls Layer to create and edit objects; Control Layer This is my persistence layer, here Ill have all the NHibernate configuration. This is my critic point, because ListSingleton Project will have only my RemoteObject. (Here I have the App.config file) Models Layer Entity layer. Here I only have the entities classes and their respective mapping. I’ve done a test solution with no remoting and only with the projects of the Control and Model Layers. It was all working ok. Now that I added the Views Layer and set the solution to start with projects Client and Server (Client calls the Control Layer and this would do a try to persist a object) I’m getting a error at : Configuration cfg = new Configuration(); cfg.AddXmlFile("mapping/User.hbm.xml"); InnerException: {"Could not compile the mapping document: mapping/User.hbm.xml"} InnerException.InnerException: {"Could not find the dialect in the configuration"} StackTrace in the InnerException.InnerException " em NHibernate.Dialect.Dialect.GetDialect(IDictionary`2 props)\r\n em NHibernate.Cfg.Configuration.AddValidatedDocument(NamedXmlDocument doc)" But I know that there is no error in the mapping file because I used in my test application.

  • Lazy non-modifiable list

    - by mindas
    I was looking for a decent implementation of a generic lazy non-modifiable list implementation to wrap my search result entries. The unmodifiable part of the task is easy as it can be achieved by Collections.unmodifiableList() so I only need to sort out the the lazy part. Surprisingly, google-collections doesn't have anything to offer; while LazyList from Apache Commons Collections does not support generics. I have found an attempt to build something on top of google-collections but it seems to be incomplete (e.g. does not support size()), outdated (does not compile with 1.0 final) and requiring some external classes, but could be used as a good starting point to build my own class. Is anybody aware of any good implementation of a LazyList? If not, which option do you think is better: write my own implementation, based on google-collections ForwardingList, similar to what Peter Maas did; write my own wrapper around Commons Collections LazyList (the wrapper would only add generics so I don't have to cast everywhere but only in the wrapper itself); just write something on top of java.util.AbstractList; Any other suggestions are welcome.

  • How to minify JS in PHP easily...Or something else

    - by RickyAYoder
    I've done some looking around, but I'm still confused a bit. I tried Crockford's JSMin, but Win XP can't unzip the executable file for some reason. What I really want though is a simple and easy-to-use JS minifier that uses PHP to minify JS code--and return the result. The reason why is because: I have 2 files (for example) that I'm working between: scripts.js and scripts_template.js scripts_template is normal code that I write out--then I have to minify it and paste the minified script into scripts.js--the one that I actually USE on my website. I want to eradicate the middle man by simply doing something like this on my page: <script type="text/javascript" src="scripts.php"></script> And then for the contents of scripts.php: <?php include("include.inc"); header("Content-type:text/javascript"); echo(minify_js(file_get_contents("scripts_template.js"))); This way, whenever I update my JS, I don't have to constantly go to a website to minify it and re-paste it into scripts.js--everything is automatically updated. Yes, I have also tried Crockford's PHP Minifier and I've taken a look at PHP Speedy, but I don't understand PHP classes just yet...Is there anything out there that a monkey could understand, maybe something with RegExp? How about we make this even simpler? I just want to remove tab spaces--I still want my code to be readable. It's not like the script makes my site lag epically, it's just anything is better than nothing. Tab removal, anyone? And if possible, how about removing completely BLANK lines?

  • RegularExpression-esque search matching Objects in List

    - by Pindatjuh
    I'm currently working on an implementation of the following idea, and I was wondering if there is any literature on this subject. Working with Java, but the principle applies on any language with a decent type-system, I like to implement: matching Objects from a List using a RegularExpression-esque search: So let's say I have a List containing List<Object> x = new ArrayList<Object>(); x.add(new Object()); x.add("Hello World"); x.add("Second String"); x.add(5); // Integer (auto-boxing) x.add(6); // Integer Then I create a "Regular Expression" (not working with a stream of characters, but working with a stream of Objects), and instead of character-classes, I use type-system properties: [String][Integer] And this would match one sublist: {Match["Second String", 5]}. The expression: [String:length()<15] Will match two sublist (each of length 1) containing a String which instance is passing the expression instance.length() < 5: {Match["Hello World"],Match["Second String"]}. [Object][Object] Matches any pair in the List: {Match[Object,"Hello World"],Match["Second String", 5]}, in a streamed manner (no overlapping matches). Ofcourse, my implementation will have grouping, lookahead/lookbehinds and is hierarchical (i.e. matching n elements from Lists in Lists), etc. The above merely illustrates the concept. Is there a name for this principle, and is there literature available on it?

  • How to create a JAX-RS service where the sub-resource @Path doesn't have a leading slash

    - by Matt
    I've created a JAX-RS service (MyService) that has a number of sub resources, each of which is a subclass of MySubResource. The sub resource class being chosen is picked based on the parameters given in the MyService path, for example: @Path("/") @Provides({"text/html", "text/xml"}) public class MyResource { @Path("people/{id}") public MySubResource getPeople(@PathParam("id") String id) { return new MyPeopleSubResource(id); } @Path("places/{id}") public MySubResource getPlaces(@PathParam("id") String id) { return new MyPlacesSubResource(id); } } where MyPlacesSubResource and MyPeopleSubResource are both sub-classes of MySubResource. MySubResource is defined as: public abstract class MySubResource { protected abstract Results getResults(); @GET public Results get() { return getResults(); } @GET @Path("xml") public Response getXml() { return Response.ok(getResults(), MediaType.TEXT_XML_TYPE).build(); } @GET @Path("html") public Response getHtml() { return Response.ok(getResults(), MediaType.TEXT_HTML_TYPE).build(); } } Results is processed by corresponding MessageBodyWriters depending on the mimetype of the response. While this works it results in paths like /people/Bob/html or /people/Bob/xml where what I really want is /people/Bob.html or /people/Bob.xml Does anybody know how to accomplish what I want to do?

  • Data Flow Object Graph and An Execution Engine for it

    - by M Dotnet
    I would like to build a custom workflow engine from scratch. The input to this workflow is a data flow diagram which is composed of a series of activities connected together through lines where each each represent the data flow. Each activity can export multiple outputs. Activities are complex math functions but the logic is hidden from the user. My workflow engine job is to execute the given data flow diagram. Each activity within the data flow diagram is a custom activity and each activity can output different outputs. How do you suggest to model the data flow diagram object? I need to be able to construct the data flow diagram problematically (no need for drag and drop) but I need to display the final result graphically (for display and debugging purposes). Are there any libraries out there that I could use? Should I keep the workflow presentable as an xml? I know that there are many projects out there trying to essentially doing similar thing by building such workflow engines but I need something light weight and open source. I do not need any state machine execution engine and mine is primarily sequential workflow with fork and join capabilities. My activities are wrappable as basic C# classes and I do NOT want to use anything as heavy as .NET workflow foundation.
