  • JSF don't find component in view root with the form id

    - by kenzokujpn
    I have a t:inputFileUpload inside the form, in the html of the display page the id of this component is form:inputFile but when I tried to get the component from the view root using "form:inputFile" the return is null, but when the "form:" is removed the return is the component. The component don't set the value in my managed bean, someone have this problem? EDIT: <h:form id="form" enctype="multipart/form-data"> <t:inputFileUpload id="inputFile" size="40" value="#{managedBean.inputFile}"/> </h:form> In the managed bean: private UploadedFile inputFile; with the gets and sets provided by Eclipse. //This method scans the view root and returns the component with the id passed as parameter findComponentInRoot("form:inputFile"); This returns null, but when I use: //This method scans the view root and returns the component with the id passed as parameter findComponentInRoot("inputFile"); The return is the component I'm looking for, but when I use the View Source in Internet Explorer the id of this component is "form:inputFile". I don't know if this is related, but the component don't set the value in my managed bean and it's strange the fact that the id of the component is different from the HTML source. I'm using JSF 1.2 Mojarra. Someone else has this problem? Or know why this happens?

  • Single log file for multiple webapps

    - by Ashish Aggarwal
    In my tomcat there are multiple webapps deployed and they communicate with each other. Currently they all have their own log file. But when there is some issue comes from call I have to 1st check with the app to whom I made a call and check log file of respective apps involved in the call. So I want that, as all apps is deployed in same tomcat and sharing a common log4j, if a call made to any app then all logs should be in a single log file and no matters how my webapps are involved all error comes from any webapp during the call should be in a single log file. I have no idea how can I achieve this. So any help is appreciable. Edited: I think my question is not cleared so updated with use case: I have three webapps A, B, C having logs files as A.log, B.log and C.log. I made two calls. 1st one to A (that internally calls C) and 2nd to B (that internally calls C). Now logging of first call must be in A.log (with the logs of every step performed inside the webapp c) and second call must be in B.log (with the logs of every step performed inside the webapp c).

  • Hierarchical data table for JSF2 and RichFaces

    - by Iravanchi
    I'm using RichFaces on my JSF2 application, and I need a way to have something like a tree-column or tree-table. As far as I know, there's no support for such thing in RichFaces. Something's mentioned for RichFaces 4.0, but the priority of this in their plan isn't promising at all, and I don't think that it's going to be included in 4.0. I know there's a tree table available in IceFaces, but I'd rather not add another library to avoid conflicts and learning curve and ... So, I'm looking for the simplest way that I can achieve the same results with minimum efforts, maybe using sub-tables in RichFaces? Any ideas would be appreciated.

  • Detecting struckout text in a cell using JExcelApi

    - by Geo
    I need to detect whether the text within a cell is struck out or not. I'm using this: Cell cc = sheet.getCell("B1"); CellFormat format = cc.getCellFormat(); System.out.println(format.getFont().isStruckout()); but I remember I read somewhere that CellFormat is deprecated and CellFeatures should be used instead. How could one find out whether a text is struck out using CellFeatures?

  • SWT Drag and Drop support for Text widget

    - by bryantsai
    I've written an application recently using SWT. In one of its dialog box, I have a few widgets, one of which is Text, which is designed to support DND with other widgets. I've first added DND support for the 2 Tree widgets on the same dialog box (both drag source and drop target). Before I added DND support for that Text widget, I noticed that on Linux platform (gtk), SWT Text widget automatically get drag and drop support. That is, I can already drag from the other Tree widgets and drop on this Text (at any position to inserted there), as well as selecting and dragging any text from this Text to other Tree or Text widget. However, this is only working on Linux platform but not on Windows. The same program, if running on Windows, will not have any DND support for that Text widget (Tree widgets of course have DND support since I specifically write for them). So here's what I want to achieve on Windows as well: drop text at any position in Text widget. before dropping and while hovering, able to see the caret position clearly where the intended position to drop. caret position should move along with the mouse cursor. support multi-line in Text widget SOLUTION: DropTarget target = new DropTarget(sytledText, DND.DROP_MOVE | DND.DROP_COPY); target.setTransfer(new Transfer[] { TextTransfer.getInstance() }); target.addDropListener(new StyleTextDropTargetEffect(sytledText)); Use StyledText instead of Text widget Use StyledTextDropTargetEffect (or extend it) and add it as dr op listener

  • CloseHandler<Window> and Window.ClosingHandler() working differently in IE

    - by stuff22
    It seems that CloseHandler and Window.ClosingHandler() are not working or are not triggering the events in the same way under IE as opposed to Firefox. Window.addWindowClosingHandler(new Window.ClosingHandler() { @Override public void onWindowClosing(ClosingEvent event) { event.setMessage(message); } Window.addCloseHandler(new CloseHandler<Window>() { @Override public void onClose(CloseEvent<Window> event) { //Window.alert("debug1"); if(recordId!=null){ DatabaseQueryServiceAsync dbQueryService = DatabaseQueryService.Util.getInstance(); dbQueryService.releaseRecordLock(recordId, new AsyncCallback<String>() { @Override public void onFailure(Throwable arg0) { } @Override public void onSuccess(String arg0) { } }); } } }); }); For example, the ClosingHandler under IE displays the message when I swap a panel within within my widget. This does not occur in Firefox. The CloseHandler doesn't seem to trigger at all when the window closes in IE, but does so in firefox. The interesting thing to point out there, is that when I put a Window.alert("debug1") message in the addCloseHandler() method it DOES run the callback below, but as soon as I remove it, the callback doesn't happen. In firefox it works and runs the callback in both situations. So, I'm basically pulling my hair out not really understanding what's going on. Any help would be greatly appreciated. Thanks.

  • SWT: scrollable area within a tab

    - by DaveJohnston
    I am trying to add a scrollable area to my tabbed window. So far I have a CTabFolder in a shell. I have added 5 CTabItems to it and everything works as expected. On one of my CTabItems the contents are too big to fit on the screen so I would like to be able to scroll. The contents is a collection of Groups each containing various widgets. So the CTabFolder is created as follows: CTabFolder tabs = new CTabFolder(shell, SWT.BORDER); tabs.setSimple(false); tabs.setUnselectedImageVisible(false); tabs.setUnselectedCloseVisible(false); tabs.setMinimizeVisible(false); tabs.setMaximizeVisible(false); FormData tabsLayoutData = new FormData(); tabsLayoutData.top = new FormAttachment(0, 5); tabsLayoutData.left = new FormAttachment(0, 5); tabsLayoutData.bottom = new FormAttachment(92, 0); tabsLayoutData.right = new FormAttachment(100, -5); tabs.setLayoutData(tabsLayoutData); Then the CTabItem: CTabItem tab = new CTabItem(tabs, SWT.NONE); tab.setText("Role"); Then the contents: Composite tabArea = new Composite(tabs, SWT.V_SCROLL); tabArea.setLayout(new FormLayout()); tab.setControl(tabArea); So the groups contained within the tab are created with tabArea as the parent and everything appears as you would expect. The problem is though that the vertical scroll bar is always present but doesn't seem to do anything. The contents are chopped off at the bottom of the tabArea composite. Is there anything else I need to do to get the scrolling to work properly?

  • Change classloader

    - by Chris
    I'm trying to switch the class loader at runtime: public class Test { public static void main(String[] args) throws Exception { final InjectingClassLoader classLoader = new InjectingClassLoader(); Thread.currentThread().setContextClassLoader(classLoader); Thread thread = new Thread("test") { public void run() { System.out.println("running..."); // approach 1 ClassLoader cl = TestProxy.class.getClassLoader(); try { Class c = classLoader.loadClass("classloader.TestProxy"); Object o = c.newInstance(); c.getMethod("test", new Class[] {}).invoke(o); } catch (Exception e) { e.printStackTrace(); } // approach 2 new TestProxy().test(); }; }; thread.setContextClassLoader(classLoader); thread.start(); } } and: public class TestProxy { public void test() { ClassLoader tcl = Thread.currentThread().getContextClassLoader(); ClassLoader ccl = ClassToLoad.class.getClassLoader(); ClassToLoad classToLoad = new ClassToLoad(); } } (it is not relevant what the InjectingClassLoader is) I'd like to make the result of "approach 1" and "approach 2" exactly same, but it looks like thread.setContextClassLoader(classLoader) does nothing and the "approach 2" always uses the system classloader (can be determined by comparing tcl and ccl variables while debugging). Is it possible to make all classes loaded by new thread use given classloader?

  • JFrame is not acting as expected!

    - by DasWood
    This is my first time using a JFrame. I can't get the window to display the text areas I've nested inside the JFrame. I am trying to get the text field with my name in it to display above the tabulated results, which I have omitted the formatting for until I can get the JFrame to work. public void printResults(String[] names, int[] temp, int[][] scores, float[] averages, char[] letters){ JTextArea outarea= new JTextArea(5,20); JTextArea name = new JTextArea(5,20); Font font = new Font("Tahoma", Font.BOLD, 48); name.setFont(font); name.setText("Made By Durka Durka"); JFrame window = new JFrame(); window.getContentPane().add(name); window.getContentPane().add(outarea); window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); window.pack(); window.getContentPane().setVisible(true) String out = "twat"; outarea.setText(out); //JOptionPane.showMessageDialog(null,window); }

  • Bytecode and Objects

    - by HH
    Hey everyone, I am working on a bytecode instrumentation project. Currently when handling objects, the verifier throws an error most of the time. So I would like to get things clear concerning rules with objects (I read the JVMS but couldn't find the answer I was looking for): I am instrumenting the NEW instruction: original bytecode NEW <MyClass> DUP INVOKESPECIAL <MyClass.<init>> after instrumentation NEW <MyClass> DUP INVOKESTATIC <Profiler.handleNEW> DUP INVOKESPECIAL <MyClass.<init>> Note that I added a call to Profiler.handleNEW() which takes as argument an object reference (the newly created object). The piece of code above throws a VerificationError. While if I don't add the INVOKESTATIC (leaving only the DUP), it doesn't. So what is the rule that I'm violating? I can duplicate an uninitialized reference but I can't pass it as parameter? I would appreciate any help. Thank you

  • Why do I get empty request from the Jakarta Commons HttpClient?

    - by polyurethan
    I have a problem with the Jakarta Commons HttpClient. Before my self-written HttpServer gets the real request there is one request which is completely empty. That's the first problem. The second problem is, sometimes the request data ends after the third or fourth line of the http request: POST / HTTP/1.1 User-Agent: Jakarta Commons-HttpClient/3.1 Host: 127.0.0.1:4232 For debugging I am using the Axis TCPMonitor. There every things is fine but the empty request. How I process the stream: StringBuffer requestBuffer = new StringBuffer(); InputStreamReader is = new InputStreamReader(socket.getInputStream(), "UTF-8"); int byteIn = -1; do { byteIn = is.read(); if (byteIn > 0) { requestBuffer.append((char) byteIn); } } while (byteIn != -1 && is.ready()); String requestData = requestBuffer.toString(); How I send the request: client.getParams().setSoTimeout(30000); method = new PostMethod(url.getPath()); method.getParams().setContentCharset("utf-8"); method.setRequestHeader("Content-Type", "application/xml; charset=utf-8"); method.addRequestHeader("Connection", "close"); method.setFollowRedirects(false); byte[] requestXml = getRequestXml(); method.setRequestEntity(new InputStreamRequestEntity(new ByteArrayInputStream(requestXml))); client.executeMethod(method); int statusCode = method.getStatusCode(); Have anyone of you an idea how to solve these problems?

  • How to disable expand sign in Swing JTree?

    - by user2899630
    I'm working in Swing and I would like to disable the expand (plus [+]) sign on a certain type of nodes. Not sure how to do it because my nodes aren't leaves and I also cannot use setShowsRootHandles (which is only for the root). I'm referring to to JTree: suppose i got this structure: Root --[+] node1 --[+] node2 when I load this structure i would like not to see the [+] sign on node2 (because it a special type node). But I also would like to expand it by using a special command. I've overridden isLeaf() (method from DefaultMutableTreeNode) so it would set to to TRUE when i'm in the special type node, but then when I'm trying to expand it, it wouldn't expand because isLeaf() == TRUE... Hope this will make things more clear.

  • Which text margin does SWT Table use when drawing text?

    - by Zordid
    I got a relatively easy question - but I cannot find anything anywhere to answer it. I use a simple SWT table widget in my application that displays only text in the cells. I got an incremental search feature and want to highlight text snippets in all cells if they match. So when typing "a", all "a"s should be highlighted. To get this, I add an SWT.EraseItem listener to interfere with the background drawing. If the current cell's text contains the search string, I find the positions and calculate relative x-coordinates within the text using event.gc.stringExtent - easy. With that I just draw rectangles "behind" the occurrences. Now, there's a flaw in this. The table does not draw the text without a margin, so my x coordinate does not really match - it is slightly off by a few pixels! But how many?? Where do I retrieve the cell's text margins that table's own drawing will use? No clue. Cannot find anything. :-( Bonus question: the table's draw method also shortens text and adds "..." if it does not fit into the cell. Hmm. My occurrence finder takes the TableItem's text and thus also tries to mark occurrences that are actually not visible because they are consumed by the "...". How do I get the shortened text and not the "real" text within the EraseItem draw handler? Thanks!

  • Server Emulator Design Pattern

    - by adisembiring
    I wanna build server socket emulator, but I want implement some design pattern there. I will described my case study that I have simplified like these: My Server Socket will always listen client socket. While some request message come from the client socket, the server emulator will response the client through the socket. the response is response code. '00' will describe request message processed successfully, and another response code expect '00' will describe there are some error while processing the message request. IN the server there are some UI, this UI contain check response parameter such as. response code timeout interval While the server want to response the client message, the response code taken from input parameter response form UI check the timeout interval, it will create sleep thread and the interval taken from timeout interval input from UI. I have implement the function, but I create it in one class. I feel it so sucks. Can you suggest me what class / interface that I must create to refactor my code.

  • How to force HtmlUnit to save page?

    - by booroondook
    Hello. I'm using HtmlUnit to click on a HtmlElement that triggers Javascript action: currentPage = ((HtmlElement) currentPage.getByXPath("//*[contains(@onclick, 'check();')]").get(0)).click(); The element is: <a href="#" onclick="check(); return false;"> The page returned is quite similar to the page, containing that element: same URL, mostly same HTML, but there are some minor differences in the HTML and HtmlUnit doesn't save the new page. I'm using HttpAnalyzer to sniff the traffic and I see that the Webclient correctly handles JS and send the right request. The response is also correct, but when I dump the contents of the currentPage to a file, I see that the actual page didn't change. How can I fix it?

  • Jpa subclass mapping

    I am making a POS like system. I wonder how to map subclass using JPA (this is for my DAO). Product class has product details and OrderProduct class has information about the Product and details about the order. @Entity @Table(name="products") public class Product implements Serializable{ @Id @Column(name="id") @GeneratedValue(strategy = GenerationType.AUTO public int getId(){ return id;} /** Other get/set methods */ } @Entity @Table(name="order_products") public class OrderProduct extends Product{ @Id @Column(name="id") @GeneratedValue(strategy = GenerationType.AUTO) public int getId(){ return id;} /** Other get/set methods */ } I got complain about duplicate @Id. But OrderProduct class really need another id than the product one. How should I map this? DB is something like this Table products id int name varchar(32) Table order_product id int quantity int productid int fk referencing product table Would @IdClass or @AttributeOverride help?

  • Can I connect to SQL from JavaScript MVC?
