  • Updating to Spring 2.5.5 causes a javax.servlet.UnavailableException: org.springframework.web.struts

    - by Averroes
    I have been told to update some application from Spring 2.0.8 to Spring 2.5.5. This application is using Struts 1.2.7. Once I change the Spring.jar I get the following exception while loading in JBoss 4.0.5: 10:14:57,579 ERROR [[/PortalRRHH]] Servlet /PortalRRHH threw load() exception javax.servlet.UnavailableException: org.springframework.web.struts.DelegatingTilesRequestProcessor This is defined in the struts-config.xml this way: <controller locale="true"> <set-property property="processorClass" value="org.springframework.web.struts.DelegatingTilesRequestProcessor"/> </controller> I have no clue of what is happening since it works with the old version of Spring and the DelegatingTilesRequestProcessor is still available in Spring 2.5.5. I have no previous experience with Struts so if you need anything else to figure what the problem is please ask and I will update the question. Thanks.

  • Why linking doesn't work in my Xtext-based DSL?

    - by reprogrammer
    The following is the Xtext grammar for my DSL. Model: variableTypes=VariableTypes predicateTypes=PredicateTypes variableDeclarations= VariableDeclarations rules=Rules; VariableType: name=ID; VariableTypes: 'var types' (variableTypes+=VariableType)+; PredicateTypes: 'predicate types' (predicateTypes+=PredicateType)+; PredicateType: name=ID '(' (variableTypes+=[VariableType|ID])+ ')'; VariableDeclarations: 'vars' (variableDeclarations+=VariableDeclaration)+; VariableDeclaration: name=ID ':' type=[VariableType|ID]; Rules: 'rules' (rules+=Rule)+; Rule: head=Head ':-' body=Body; Head: predicate=Predicate; Body: (predicates+=Predicate)+; Predicate: predicateType=[PredicateType|ID] '(' (terms+=Term)+ ')'; Term: variable=Variable; Variable: variableDeclaration=[VariableDeclaration|ID]; terminal WS: (' ' | '\t' | '\r' | '\n' | ',')+; And, the following is a program in the above DSL. var types Node predicate types Edge(Node, Node) Path(Node, Node) vars x : Node y : Node z : Node rules Path(x, y) :- Edge(x, y) Path(x, y) :- Path(x, z) Path(z, y) When I used the generated Switch class to traverse the EMF object model corresponding to the above program, I realized that the nodes are not linked together properly. For example, the getPredicateType() method on a Predicate node returns null. Having read the Xtext user's guide, my impression is that the Xtext default linking semantics should work for my DSL. But, for some reason, the AST nodes of my DSL don't get linked together properly. Can anyone help me in diagnosing this problem?

  • Add subversion revision to war manifest using maven2

    - by feniix
    I want to find a maven native (i.e. without calling external programs) to inject the svn revision in the war manifest. Does anybody know a way to do that? I found mention to how to add the subversion revision to manifests in jar files but not with war files. I searched SO but could not find this issue specifically.

  • JSF 2.0 Dynamic Views

    - by Robe Eleckers
    Hello, I'm working on a web project which uses JSF 2.0, PrimeFaces and PrettyFaces as main frameworks / libraries. The pages have the following (common) structure: Header, Content, Footer. Header: The Header always contains the same menu. This menu is a custom component, which generates a recursive html <ul><li> list containing <a href="url"> html links, this is all rendered with a custom renderer. The link looks like 'domain.com/website/datatable.xhtml?ref=2'. Where the ref=2 used to load the correct content from the database. I use prettyfaces to store this request value in a backingbean. Question 1: Is it ok to render the <a href> links myself, or should I better add an HTMLCommandLink from my UIComponent and render that in the encodeBegin/End? Question 2: I think passing variables like this is not really the JSF 2.0 style, how to do this in a better way? Content: The content contains dynamic data. It can be a (primefaces) datatable, build with dynamic data from the database. It can also be a text page, also loaded from the database. Or a series of graphs. You got the point, it's dynamic. The content is based on the link pressed in the header menu. If the content is of type datatable, then I put the ref=2 variable to a DataTableBean (via prettyfaces), which then loads the correct datatable from the database. If the content is of type chart, I'll put it on the ChartBean. Question 3: Is this a normal setup? Ideally I would like to update my content via Ajax. I hope it's clear :)

  • How can one extract rdf:about or rdf:ID properties from triples using SPARQL?

    - by lennyks
    It seemed a trivial matter at the beginning but so far I have not managed to get the unique identifier for a given resource using SPARQL. What I mean is given, e.g., rdf:Description rdf:about="http://..." and then some properties identifying this resource, what I want to do is to first find this very resource and then retrieve all the triples given some URI. I have tried naïve approaches by writing statements in a WHERE clause such as: ?x rdf:about ?y and ?x rdfs:about ?y I hope I am being precise.

  • Using JSF, PrimeFaces and JPA: Create Basic WebApp without using Generated CRUD Classes, Forms, etc

    - by user2774489
    I am trying to build a basic CRUD application with NetBeans 7.4, JSF, PrimeFaces and JPA using MySQL. I have successfully done this by using the NetBeans wizards. I want to do this from scratch, no wizards. There seems to be a lack of support for the combo of JSF, PrimeFaces and JPA. When I say "lack", I mean a full example (I might be asking too much), without using the CRUD auto-gen templates/classes AND shows actual queries coded and passed to the datatables(primefaces). YouTube is full of non-English speaking examples using Hibernate (not JPA) and other examples that show flashy GUI's with no code. So far I understand you need an @Entity class (provides the physical build of the tables), a Controller (serializable) and the .xhtml web page to show the datatable.. what else? Also, I'm not seeing any posts or examples where queries are using with JPA/JSF and how they are tied together (in one place). I need to connect the dots here so that I can leverage JSF/JPA to create simple queries to populate my PF DataTables. I've read the blogs and I've googled the intranets until I'm blue in the face. Sending me a list of URL's to read to learn about each product is something I've already done. I get what they do independently, but am looking for the "How do they all connect" answer with maybe some basic code examples!! :)

  • Google Collections sources don't compile

    - by Carl Rosenberger
    I just downloaded the Google Collections sources and imported them into a new Eclipse project with JDK 1.6. They don't compile for a couple of reasons: javax.annotation.Nullable can not be found javax.annotation.ParametersAreNonnullByDefault can not be found Cannot reduce the visibility of the inherited method #createCollection() from AbstractMultimap + 11 similar ones Name clash: The method forcePut(K, V) of type AbstractBiMap has the same erasure as forcePut(Object, Object) of type BiMap but does not override it + 2 similar ones What am I missing? I also wonder if unit tests for these collections are available to the public.

  • Using Google Common Collection in GWT

    - by Jeeyoung Kim
    This is a simple problem, but I'm having problems with it... I'm trying to use Google common collection's Objects.equal() method in a GWT client code, but I'm keep getting the error "20:12:10.001 [ERROR] [gwt_regex] Line 39: No source code is available for type com.google.common.base.Objects; did you forget to inherit a required module?" Tried to Google for the answer, but couldn't find any answer regarding this - everyone just said "Google collection should work off the box with GWT".

  • KeyListener problem

    - by rgksugan
    In my apllication i am using a jpanel in which i want to add a key listener. I did it. But it doesnot work. Is it because i am using a swingworker to update the contents of the panel every second. Here is my code to update the panel RenderedImage image = ImageIO.read(new ByteArrayInputStream((byte[]) get())); Graphics graphics = remote.rdpanel.getGraphics(); if (graphics != null) { Image readyImage = new ImageIcon(UtilityFunctions.convertRenderedImage(image)).getImage(); graphics.drawImage(readyImage, 0, 0, remote.rdpanel.getWidth(), remote.rdpanel.getHeight(), null); }

  • Not showing error when calling another function in Spring

    - by Javi
    Hello, I have a controller with 2 methods. The first one just add some lists to the model (the lists of my comboboxes) and return a JSP with a form. The second one validates the data and if there aren't errors it saves the data. The code looks like this: public String showForm(Model model){ //load some data into some lists return "tiles:myJSPfile"; } public String save(@Valid @ModelAttribute("MyData") Data data, BindingResult result, Model model){ if(result.hasErrors()){ //there are errors: show form with error messages //(but I need to reload the combobox lists) return showForm(model); } //save data } The problem is that in this way I don't see the error messages in the form (though I see by the debugger that it has found errors). I've thought that the problem comes because the showForm method doesn't have the error messages because it can't see the BindingResult, so I've added BindingResult as a parameter of showForm method, but it still doesn't work. I've added My Model Attribute as well but I get the same problem. If I just return the JSP file in the save method I can see the errors, but in this way I would need to add again in this other method the lists I had already added in the showForm (duplicated code). I can't save the data in session scope so it's compulsory to get again the lists after getting the error. if(result.hasErrors()){ //there are errors: show form with error messages return "tiles:myJSPfile"; } Why are errors not shown when I call a function to display my JSP different from the one I used for the validation? What's the best way to do this? Thanks.

  • GAE/J: unable to register a custom ELResolver

    - by dfa
    I need to register a custom ELResolver for a Google App Engine project. Since it must be registered before any request is received, as specified by the Javadoc: It is illegal to register an ELResolver after the application has received any request from the client. If an attempt is made to register an ELResolver after that time, an IllegalStateException is thrown. I'm using a ServletContextListener: public class RegisterCustomELResolver implements ServletContextListener { @Override public void contextInitialized(ServletContextEvent sce) { ServletContext context = sce.getServletContext(); JspApplicationContext jspContext = JspFactory.getDefaultFactory().getJspApplicationContext(context); jspContext.addELResolver(new MyELResolver()); } ... } The problem is that JspFactory.getDefaultFactory() returns always null. I've alreay filled a bug report. Any idea for a workaround?

  • Persist collection of interface using Hibernate

    - by Olvagor
    I want to persist my litte zoo with Hibernate: @Entity @Table(name = "zoo") public class Zoo { @OneToMany private Set<Animal> animals = new HashSet<Animal>(); } // Just a marker interface public interface Animal { } @Entity @Table(name = "dog") public class Dog implements Animal { // ID and other properties } @Entity @Table(name = "cat") public class Cat implements Animal { // ID and other properties } When I try to persist the zoo, Hibernate complains: Use of @OneToMany or @ManyToMany targeting an unmapped class: blubb.Zoo.animals[blubb.Animal] I know about the targetEntity-property of @OneToMany but that would mean, only Dogs OR Cats can live in my zoo. Is there any way to persist a collection of an interface, which has several implementations, with Hibernate?

  • Closing Connections on asynchronous messaging in JMS

    - by The Elite Gentleman
    Hi Everyone! I have created a JMS wrapper (similar to Springs JmsTemplate since I'm not using Springs) and I was wondering: If I setup asynchronous messaging, when is a good time to close connections and JMS relates resources (so that the Connection Factory in the Resource Pool can be available)? Thanks Here's the source code for receiving JMS messages public Message receive() throws JMSException { QueueConnection connection = null; QueueSession session = null; QueueReceiver consumer = null; try { // TODO Auto-generated method stub connection = factory.createQueueConnection(); if (connection != null && getExceptionListener() != null) { connection.setExceptionListener(getExceptionListener()); } session = connection.createQueueSession(isSessionTransacted(), getAcknowledgeMode()); consumer = session.createReceiver(queue); if (getMessageListener() != null) { consumer.setMessageListener(getMessageListener()); } //Begin connection.start(); if (getMessageListener() == null) { return null; } return receive(session, consumer); } catch (JMSException e) { // TODO: handle exception logger.error(e.getLocalizedMessage(), e); throw e; } finally { JMSUtil.closeMessageConsumer(consumer); JMSUtil.closeSession(session, false); //false = don't commit. JMSUtil.closeConnection(connection, true); //true = stop before close. } As you can see, if getMessageListener() != null then apply it to the MessageConsumer. Am I doing this correctly? The same approach has also been taken for JMS Topic.

  • Correct way to persist Quartz triggers

    - by davioooh
    I'm quite new to Quartz and now I need to schedule some jobs in Spring Web App. I know about Spring + Quartz integration (I'm using Spring v 3.1.1) but I'm wondering if it's the right way to follow. In particular I need to persist my scheduled tasks in a DB so I can re-initialize them when application is restarted. Are there some utilities provided by Spring scheduling wrapper to do this? Can you suggest me some "well known" approach to follow?

  • Fast, lightweight XML parser

    - by joe90
    I have a specific format XML document that I will get pushed. This document will always be the same type so it's very strict. I need to parse this so that I can convert it into JSON (well, a slightly bastardized version so someone else can use it with DOJO). My question is, shall I use a very fast lightweight (no need for SAX, etc.) XML parser (any ideas?) or write my own, basically converting into a StringBuffer and spinning through the array? Basically, under the covers I assume all HTML parsers will spin thru the string (or memory buffer) and parse, producing output on the way through. Thanks //edit Thanks for the responses so far :) The xml will be between 3/4 lines to about 50 max (at the extreme)..
