  • Update rich:dataTable binding on Ajax selectionchange

    - by MilkJug
    I want to find the current selection of the data table whenever a selection changes. I can update other items using: <a4j:ajax render=":tmp,:tmp2" event="selectionchange"> But I cannot find the current selection - I think the major issue is that the UIExtendedDataTable backing does not get updated on the Ajax request. Is there a way to update the current selection on a selectionchange (Using RichFaces 4)?

  • Does a servlet knows the encoding of the sent form that specified using http-equiv?

    - by Daziplqa
    Does a servlet knows the encoding of the sent form that specified using http-equiv? When I specify an encoding of a POSTed form using http-equiv like that: <HTML> <head> <meta http-equiv='Content-Type' content='text/html; charset=gb2312'/> </head> <BODY > <form name="form" method="post" > <input type="text" name="v_rcvname" value="????"> </form> </BODY> </HTML> And then at the servlet I use the method, request.getCharacterEncoding() I got null ! So, Is there a way that I can tell the server that I am encoding the data in some char encoding??

    - by Nkunzis
    I am trying to read an xml file on an http url. "Unexpected end of file from server" keeps on coming . the page is password protected, I would like to know if I am properly giving in my url authentication details. I tried with non protected pages and I can read them properly. Here is my code: URL url = new URL("http://username:[email protected]:0000/test.xml"); URLConnection yc = url.openConnection(); BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream())); String inputLine; while ((inputLine = in.readLine()) != null) System.out.println(inputLine); in.close();

  • How to build SVN/Git like Diff in WebApp?

    - by 01
    I have XMLs(or Objects) that represents data at some point in a business process. I would like to be able to see what has changed between step1 and step5(two versions of the same XML or Object). Id like to implement this like diff function in version control system. how to do it in web app? P.S. I dont want to just store those files in VCS and than make it do the diff. However if I could somehow emulate VCS without having one that would be cool. P.S. I know there are some JS frameworks that offer diff functionality, but the XML could have 10MB, so I think it should be dont at server side.

  • Converting a soap message to a document using wssj

    - by ellander
    I have been supplied with a jar file that should enable me to connect to a 3rd party system. When I run the necessary class I get an error which states that the namespace for the prefix "SOAPENV" has not been declared. Using jad I have decompiled the class files to try suss out what is going on and the error seems to occur when a soap message is being converted to a document. Unfortunately I don't know much about wssj. Can anyone suggest what the problem might be? I'm wondering if it's an incompatibility issue as it's not a recently created jar file and the decompiled code looks different to all the examples I can find. For example, in this section the examples have addNamesSpaceDeclaration rather than addAttribute... MessageFactory factory = MessageFactory.newInstance(); SOAPFactory sf = SOAPFactory.newInstance(); SOAPMessage msg = factory.createMessage(); MimeHeaders headers = msg.getMimeHeaders(); headers.addHeader("Content-Type", "text/xml"); SOAPEnvelope env = msg.getSOAPPart().getEnvelope(); env.addAttribute(sf.createName("xmlns:xsi"), "http://www.w3.org/2001/XMLSchema-instance");

  • Google App Engine/Simple HTML, how to write input boxes with google autocomplete

    - by Calm Storm
    I am writing a GAE application and I would like to have an input box with google auto-suggest. Specifically, when a user types "Shawshank" I would like to see google's suggestions in my drop down. Can someone tell me what are the different ways of doing this? I understand I may have to use some javascript libraries so any code samples etc will help immensely. (Pure javascript/jquery kinda solutions will be more preferable)

  • how to configure jetty 7 to use syslog or log4j

    - by egemen ozden
    I am looking for a way to direct all the jetty 7 logging to syslog. My current configuration dumps everything to JETTY_HOME/logs/.. After some initial ivestigation, it seems I should change JETTY_HOME/etc/jetty-logging.xml, but this does not look straightforward. It looks like I should create a new PrintStream implementation which sends its output to syslog and redirecting stderr and stdout to that class in jetty-logging.xml. any easier way to do that or to make jetty log directly to log4j ? Thanks

  • Why does this compile?

    - by akf
    I was taken aback earlier today when debugging some code to find that something like the following does not throw a compile-time exception: public Test () { HashMap map = (HashMap) getList(); } private List getList(){ return new ArrayList(); } As you can imagine, a ClassCastException is thrown at runtime, but can someone explain why the casting of a List to a HashMap is considered legal at compile time?

  • Why is BigDecimal.equals specified to compare both value and scale individually?

    - by bacar
    This is not a question about how to compare two BigDecimal objects - I know that you can use compareTo instead of equals to do that, since equals is documented as: Unlike compareTo, this method considers two BigDecimal objects equal only if they are equal in value and scale (thus 2.0 is not equal to 2.00 when compared by this method). The question is: why has the equals been specified in this seemingly counter-intuitive manner? That is, why is it important to be able to distinguish between 2.0 and 2.00? It seems likely that there must be a reason for this, since the Comparable documentation, which specifies the compareTo method, states: It is strongly recommended (though not required) that natural orderings be consistent with equals I imagine there must be a good reason for ignoring this recommendation.

  • How can I split abstract testcases in JUnit?

    - by Willi Schönborn
    I have an abstract testcase "AbstractATest" for an interface "A". It has several test methods (@Test) and one abstract method: protected abstract A unit(); which provides the unit under testing. No i have multiple implementations of "A", e.g. "DefaultA", "ConcurrentA", etc. My problem: The testcase is huge (~1500 loc) and it's growing. So i wanted to split it into multiple testcases. How can organize/structure this in Junit 4 without the need to have a concrete testcase for every implementation and abstract testcase. I want e.g. "AInitializeTest", "AExectueTest" and "AStopTest". Each being abstract and containing multiple tests. But for my concrete "ConcurrentA", i only want to have one concrete testcase "ConcurrentATest". I hope my "problem" is clear. EDIT Looks like my description was not that clear. Is it possible to pass a reference to a test? I know parameterized tests, but these require static methods, which is not applicable to my setup. Subclasses of an abstract testcase decide about the parameter.

  • resizing a ImageIcon in a JButton

    I am creating a JButton which includes a specific ImageIcon. The main issue is that the original icon size is much bigger than the button size. As result when the button is displayed, only part of the icon can be seen. What is the method that "resize" an ImageIcon i n order to make it fit inside a JButton?

  • Should I put actors in the Domain-Model/Class-Diagram?

    - by devoured elysium
    When designing both the domain-model and class-diagrams I am having some trouble understanding what to put in them. I'll give an example of what I mean: I am doing a vacations scheduler program, that has an Administrator and End-Users. The Administrator does a couple of things like registering End-Users in the program, changing their previleges, etc. The End-User can choose his vacations days, etc. I initially defined an Administrator and End-User as concepts in the domain-model, and later as classes in the class-diagram. In the class-diagram, both classes ended up having a couple of methods like Administrator.RegisterNewUser(); Administrator.UnregisterUser(int id); etc. Only after some time I realised that actually both Administrator and End-User are actors, and maybe I got this design totally wrong. Instead of filling Administrator and End-User classes with methods to do what my Use-Cases request, I could define other classes from the domain to do them, and have controllers handle the Use-Cases(actually, I decided to do one for each Use-Case). I could have a UserDatabase.RegisterNewUser() and UserDatabase.UnregisterUser(int id);, for example, instead of having those methods on the Administrator class. The idea would be to try to think of the whole vacation-scheduler as a "closed-program" that has a set of features and doesn't bother with things such as authentication, that should be internal/protected, being that the only public things I'd let the outside world see would be its controllers. Is this the right approach? Or am I getting this totally wrong? Is it generally bad idea to put Actors in the domain-model/class-diagrams? What are good rules of thumb for this? My lecturer is following Applying UML and Patterns, which I find awful, so I'd like to know where I could look up more info on this described actor-models situation. I'm still a bit confused about all of this, as this new approach is radically different from anything I've done before.

  • Expose jar resources over web

    - by Heavy Bytes
    I have a web-service (with Spring-WS). I have a jar with several schemas (schema1.xsd, schema2.xsd and schema3.xsd) which I include in my web service. Is there a way to expose the schemas from the jar through a servlet somehow in my web-service wep app? My Spring MessageDispatcherServlet is mapped to /ws/ I would like my schemas to be exposed to /schemas/schema1.xsd /schemas/schema2.xsd and so on. I have an idea how to do it with a servlet, but it's too verbose and there has to be a nicer way. The way I am thinking is have a servlet filter and everything that hits /schemas/ check if it is in my list of allowed resources and display it. This has to be a server agnostic solution. (For instance http://tuckey.org/urlrewrite/ will not work). Thanks.

  • Linked List Inserting strings in alphabetical order

    - by user69514
    I have a linked list where each node contains a string and a count. my insert method needs to inset a new node in alphabetical order based on the string. if there is a node with the same string, then i increment the count. the problem is that my method is not inserting in alphabetical order public Node findIsertionPoint(Node head, Node node){ if( head == null) return null; Node curr = head; while( curr != null){ if( curr.getValue().compareTo(node.getValue()) == 0) return curr; else if( curr.getNext() == null || curr.getNext().getValue().compareTo(node.getValue()) > 0) return curr; else curr = curr.getNext(); } return null; } public void insert(Node node){ Node newNode = node; Node insertPoint = this.findIsertionPoint(this.head, node); if( insertPoint == null) this.head = newNode; else{ if( insertPoint.getValue().compareTo(node.getValue()) == 0) insertPoint.getItem().incrementCount(); else{ newNode.setNext(insertPoint.getNext()); insertPoint.setNext(newNode); } } count++; }

  • Reset JPA generated value between tests

    - by Rythmic
    I'm running spring + hibernate + JUnit with springJunit4runner and transactional set to default rollback I'm using in-memory derbydb as Database. Hibernate is used as a JPA Provider and I am successfully testing CRUD kinds of stuff. However, I have a problem with JPA and the behaviour of @GeneratedValue If I run one of my tests in isolation, two entitys are persisted with id 1 and 2. If i run the whole test suite the ids are instead 6 and 7. Spring does rollbacks just fine so there are only these two entitys in the database after addition and of course zero before. But behaviour of @GeneratedValue doesn't allow me to reliable findById unless I would return the Id from the dao.add(Entity e) //method I don't feel like doing that for the sake of testing, or is it a good practise to return the entity that was persisted so I should be doing it anyway?

  • Resources access problem from JAR

    - by aeter
    I have the following directory structure of a project: Folder "project" in Eclipse: --folder "src" --folder "resources" ----trayicon2.png --folder "db" ----test.db --folder "bin" I'm accessing the image with: Image image = Toolkit.getDefaultToolkit().getImage("resources/trayicon2.png"); and from Eclipse that is not a problem. Then I generate an "executable jar file", and add the dirs, making a directory structure of: Folder "project" --folder "db" ----test.db --folder "resources" ----trayicon2.png --project.jar And now the image is no more accessible. Also, the database is no more accessible; while in Eclipse I used to access it with: Connection conn = DriverManager.getConnection("jdbc:sqlite:db/test.db"); How can I access the resources (images and db) after generating the jar file "project.jar"?

  • JSplitPane overlaps JButtons in BorderLayout, but does not when layout is null

    - by thaweatherman
    So I'm having another issue..... I'm currently using a BorderLayout in my GUI so that when I resize my jframe, all of the internal components resize with it. I couldn't get any other layout to work with how I want the GUI to look while providing this resizing capability. At the top I have a JMenuBar, and below it I have a bunch of buttons. Below that I am supposed to have a JSplitPane, and it is there. However, the buttons seemed to be contained within the JSplitPane, which is not my intention. So when anything happens within the splitpane, the buttons disappear until I move my mouse over them again. When I set my layout to null everything works great except I lose the resizing capability, which is not good. Tried posting images but it wont let me since my rep isnt at 10 yet :( Any suggestions? I've tried putting the buttons into a JPanel then adding the jpanel but the splitpane overlaps with that. Same with a JToolBar. The order in which I add my items is: 1) the menu bar setJMenuBar(menuBar) 2) the buttons getContentPane().add(btnZoomIn) etc. 3) the split pane getContentPane().add(splitPane) then the rest of the things you see after that
