  • JBoss 6 unpacks jars from WEB-INF/lib of war

    - by Maxym
    when I start JBoss 6 I see that it unpacks all jar files from WEB-INF/lib in tmp/vfs/automountXXX folder. E.g. jackrabbit-server.war contains library asm-3.1.jar, then in tmp folder I see the following folders with files: asm-3.1.jar-83dc35ead0d41d41/asm-3.1.jar asm-3.1.jar-2a48f1c13ec7f25d/contents/"unpacked asm-3.1.jar" it does not take files from my.ear/lib only WEB-INF/lib... Why is it so? And is here any way to prevent it doing so? It just slows down application server starting (and stopping), what is not that comfortable at development... If it is somehow related to JavaEE 6 specification and ejb-jars, which can be located now in WEB-INF/lib, so I don't have such libraries in my war files... UPDATE: actually when I repack jackrabbit-server.war to jackrabbit-server.ear which contains jackrabbit-server.war and moved all its libraries to jackrabbit-server.ear/lib then I still see two folders in tmp: asm-3.1.jar-215a36131ebb088e/asm-3.1.jar asm-3.1.jar-14695f157664f00/contents/ but in this case last folder is empty. So it still creates two folders, but does not unpack my library. Also I use exploded deployment so the question is only about jar files, not unpacking ear/war.

  • Why does DataInputStream not support integers?

    - by Jason
    I need to read in a list of numbers from a file, none of which are larger than 32767. Originally I was going to use the Scanner class to pull in the data, then I read about DataInputStream. This would work well for me, except that according to the API, it supports all primitive variables EXCEPT ints! Listed are longs, shorts, bytes, chars, booleans, ect, but no ints. I have no need for double precision from the incoming data. Is this a deliberate or unintentional oversight?

  • How to pass initialisation parameters to a web service in Netbeans

    - by Bob Roberts
    I have built a web web service with Netbeans 6.8 using the "Web Service from WSDL" wizard. It has generated the binding classes and a skeleton for the class implementing the web service. I've set some initialization parameters in web.xml, under the servlet corresponding to the web service. Now I'd like to pass those parameters to the class implementing the web service. How can this be achieved (preferably without editing any of the code auto-generated by Netbeans)?

  • 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).

  • Hibernate criteria with projection not performing query for @OneToMany mapping

    - by Josh
    I have a domain object, Expense, that has a field called initialFields. It's annotated as so: @OneToMany(fetch = FetchType.EAGER, cascade = { CascadeType.ALL }, orphanRemoval = true) @JoinTable(blah blah) private final List<Field> initialFields; Now I'm trying to use Projections in order to only pull certain fields for performance reasons, but when doing so the initialFields field is always null. It's the only OneToMany field and the only field I am trying to retrieve with the projection that is behaving this way. If I use a regular HQL query initialFields is populated appropriately, but of course I can't limit the fields. Anyone ever seen anything like this?

  • 64 bits ant.jar

    - by sonic
    I have installed 64 bits RHEL. I have following questions regarding ant.jar for the system. I was not able to find ant.jar build with 64 bit JVM from the apache website. Do I have to build it form the source code, if I intend to run the jar on 64 bit JVM? Would it speed up the build process if I use ant.jar build with 64 bit JVM and run it on 64 bit JVM?

  • how to return a list using SwingWorker

    - by Ender
    I have an assignment where i have to create an Image Gallery which uses a SwingWorker to load the images froma a file, once the image is load you can flip threw the image and have a slideshow play. I am having trouble getting the list of loaded images using SwingWorker. This is what happens in the background it just publishes the results to a TextArea // In a thread @Override public List<Image> doInBackground() { List<Image> images = new ArrayList<Image>(); for (File filename : filenames) { try { //File file = new File(filename); System.out.println("Attempting to add: " + filename.getAbsolutePath()); images.add(ImageIO.read(filename)); publish("Loaded " + filename); System.out.println("Added file" + filename.getAbsolutePath()); } catch (IOException ioe) { publish("Error loading " + filename); } } return images; } } when it is done I just insert the images in a List<Image> and that is all it does. // In the EDT @Override protected void done() { try { for (Image image : get()) { list.add(image); } } catch (Exception e) { } } Also I created an method that returns the list called getImages() what I need to get is the list from getImages() but doesn't seam to work when I call execute() for example MySwingWorkerClass swingworker = new MySwingWorkerClass(log,list,filenames); swingworker.execute(); imageList = swingworker.getImage() Once it reaches the imageList it doesn't return anything the only way I was able to get the list was when i used the run() instead of the execute() is there another way to get the list or is the run() method the only way?. or perhaps i am not understanding the Swing Worker Class.

  • Need help with writing test

    - by London
    I'm trying to write a test for this class its called Receiver : public void get(People person) { if(null != person) { LOG.info("Person with ID " + person.getId() + " received"); processor.process(person); }else{ LOG.info("Person not received abort!"); } } Here is the test : @Test public void testReceivePerson(){ context.checking(new Expectations() {{ receiver.get(person); atLeast(1).of(person).getId(); will(returnValue(String.class)); }}); } Note: receiver is the instance of Receiver class(real not mock), processor is the instance of Processor class(real not mock) which processes the person(mock object of People class). GetId is a String not int method that is not mistake. Test fails : unexpected invocation of person.getId() I'm using jMock any help would be appreciated. As I understood when I call this get method to execute it properly I need to mock person.getId() , and I've been sniping around in circles for a while now any help would be appreciated.

    Hey there. been a busy debugger today. ill give ths short version. ive made an array list that takes names from a database. then i put the contents of the arraylist into an array of strings. now i want too display the arrays contents in a JList. the weird thing is it was working earlier. and ive two methods. ones just a little practice too make sure i was adding to the Jlist correctly. so heres the key codes. this is the layout of my code. variables constructor methods in my variables i have these 3 defined String[] contactListNames = new String[5]; ArrayList<String> rowNames = new ArrayList<String>(); JList contactList = new JList(contactListNames); simple enough. in my constructor i have them again. contactListNames = new String[5]; contactList = new JList(contactListNames); //i dont have the array list defined though. printSqlDetails(); // the prinSqldetails was too make sure that the connectionw as alright. and its working fine. fillContactList(); // this is the one thats causing me grief. its where all the work happens. // fillContactListTest(); // this was the tester that makes sure its adding to the list alright. heres the code for fillContactListTest() public void fillContactListTest() { for(int i = 0;i<3;i++) { try { String contact; System.out.println(" please fill the list at index "+ i); Scanner in = new Scanner(System.in); contact = in.next(); contactListNames[i] = contact; in.nextLine(); } catch(Exception e) { e.printStackTrace(); } } } heres the main one thats supposed too work. public void fillContactList() { int i =0; createConnection(); ArrayList<String> rowNames = new ArrayList<String>(); try { Statement stmt = conn.createStatement(); ResultSet namesList = stmt.executeQuery("SELECT name FROM Users"); try { while (namesList.next()) { rowNames.add(namesList.getString(1)); contactListNames =(String[])rowNames.toArray(new String[rowNames.size()]); // this used to print out contents of array list // System.out.println("" + rowNames); while(i<contactListNames.length) { System.out.println(" " + contactListNames[i]); i++; } } } catch(SQLException q) { q.printStackTrace(); } conn.commit(); stmt.close(); conn.close(); } catch(SQLException e) { e.printStackTrace(); } } i really need help here. im at my wits end. i just cant see why the first method would add to the JList no problem. but the second one wont. both the contactListNames array and array list can print fine and have the names in them. but i must be transfering them too the jlist wrong. please help p.s im aware this is long. but trust me its the short version.

  • how to invoke a webservice from one container in another container in glassfish

    - by vinny
    I have webservices deployed on two containers in two separate servers A and B. A webMethod in 'Server A' needs to invoke a webmethod in 'Server B'. I have created a client stub for Sever B. Im trying to make 'Server A' use this client stub and talk to Server B. I get an exception while trying to instantiate the port object specifically at : service.getABCBeanPort(); (using JAX-WS library) Is my approach correct? Is there any better way of invoking a webservice on a remote server?

    I'm new to Android and am struggling to make a call to an SSL web service for an Android Application. My code is as follows: Log.v("fs", "Making HTTP call..."); HttpClient http = new DefaultHttpClient(); HttpGet request = new HttpGet("https://example.com/api"); try { String response = http.execute(request, new BasicResponseHandler()); Log.v("fs", response); } catch (Exception e) { Log.v("fs", e.toString()); } The Output is: Making HTTP call... javax.net.SSLPeerUnverifiedException: No peer certificate Any suggestions to make this work would be great.

  • JAX-RS --- How to return JSON and HTTP Status code together?

    - by masato-san
    I'm writing REST web app (Netbean6.9, JAX-RS, Toplink-essential) and trying to return JSON and Http status code. I have code ready and working just to return JSON when HTTP GET Method is called from client. Code snippet @Path("get/id") @GET @Produces("application/json") public M_?? getMachineToUpdate(@PathParam("id") String id) { //some code to return JSON . . return myJson But I also want to return HTTP status code (500, 200, 204 etc) along with returning JSON. I tried using HttpServletResponse object, response.sendError("error message", 500); But this made browser to think it's real 500 so output web page was regular Http 500 error page. What I want to is just to return status code so that my Javascript on client side can handle some logic depending on what HTTP status code is returned. (maybe just to display the error code and message on html page.) Is it possible to do so? or should HTTP status code not be used for such thing?

  • Can't change the layout of alternatives keys show on android keyboard

    - by Tebam
    I want to change the default layout which Android uses for show the alternative keys when performs a long-press on a key. Keys have an attribute "android:popupKeyboard" used for define the layout of the alternative key list (which could be a Keyboard reference) but when I use it the Android's default layout still appears. Is possible to change or override this layout?

  • How to move point on arc?

    - by bbZ
    I am writing an app that is simulating RobotArm movement. What I want to achieve, and where I have couple of problems is moving a Point on arc (180degree) that is arm range of movement. I am moving an arm by grabbing with mouse end of arm (Elbow, the Point I was talking about), robot can have multiple arms with diffrent arm lenghts. If u can help me with this part, I'd be grateful. This is what I have so far, drawing function: public void draw(Graphics graph) { Graphics2D g2d = (Graphics2D) graph.create(); graph.setColor(color); graph.fillOval(location.x - 4, location.y - 4, point.width, point.height); //Draws elbow if (parentLocation != null) { graph.setColor(Color.black); graph.drawLine(location.x, location.y, parentLocation.x, parentLocation.y); //Connects to parent if (arc == null) { angle = new Double(90 - getAngle(parentInitLocation)); arc = new Arc2D.Double(parentLocation.x - (parentDistance * 2 / 2), parentLocation.y - (parentDistance * 2 / 2), parentDistance * 2, parentDistance * 2, 90 - getAngle(parentInitLocation), 180, Arc2D.OPEN); //Draws an arc if not drawed yet. } else if (angle != null) //if parent is moved, angle is moved also { arc = new Arc2D.Double(parentLocation.x - (parentDistance * 2 / 2), parentLocation.y - (parentDistance * 2 / 2), parentDistance * 2, parentDistance * 2, angle, 180, Arc2D.OPEN); } g2d.draw(arc); } if (spacePanel.getElbows().size() > level + 1) {//updates all childElbows position updateChild(graph); } } I just do not know how to prevent moving Point moving outside of arc line. It can not be inside or outside arc, just on it. Here I wanted to put a screenshot, sadly I don't have enough rep. Am I allowed to put link to this? Maybe you got other ways how to achieve this kind of thing. Here is the image: Red circle is actual state, and green one is what I want to do. EDIT2: As requested, repo link: https://github.com/dspoko/RobotArm

  • Configuring Hadoop logging to avoid too many log files

    - by Eric Wendelin
    I'm having a problem with Hadoop producing too many log files in $HADOOP_LOG_DIR/userlogs (the Ext3 filesystem allows only 32000 subdirectories) which looks like the same problem in this question: http://stackoverflow.com/questions/2091287/error-in-hadoop-mapreduce My question is: does anyone know how to configure Hadoop to roll the log dir or otherwise prevent this? I'm trying to avoid just setting the "mapred.userlog.retain.hours" and/or "mapred.userlog.limit.kb" properties because I want to actually keep the log files. I was also hoping to configure this in log4j.properties, but looking at the Hadoop 0.20.2 source, it writes directly to logfiles instead of actually using log4j. Perhaps I don't understand how it's using log4j fully. Any suggestions or clarifications would be greatly appreciated.

  • Check if there are any repeated elements in an array recursively

    - by devoured elysium
    I have to find recursively if there is any repeated element in an integer array v. The method must have the following signature: boolean hasRepeatedElements(int[] v) I can't see any way of doing that recursively without having to define another method or at least another overload to this method (one that takes for example the element to go after or something). At first I thought about checking for the current v if there is some element equal to the first element, then creating a new array with L-1 elements etc but that seems rather inefficient. Is it the only way? Am I missing here something?

  • Missing JAXB classes from XMLschema.xsd

    Hi, I'm working on a xml schema resolver and I'm using JAXB with XMLSchema.xsd. I experience problems with JAXB, because I don't get classes for all the top level elements. For example for <xs:element name="maxLength" id="maxLength" type="xs:numFacet"> I do not get a class MaxLength or anything like that. Only NumFacet exists. Anyone else experienced that and could please help me? Cheers, XLR

  • Find a base case for a recursive void method

    - by Evan S
    I am doing homework. I would like to build a base case for a recursion where ordering given numbers (list2) in ascending order. Purpose of writing this codes is that when all numbers are in ascending order then should stop calling a method called ascending(list2, list1); and all values in list2 should be shipped to list1. For instance, list2 = 6,5,4,3,2,1 then list2 becomes empty and list1 should be 1,2,3,4,5,6. I am trying to compare result with previous one and if matches then stop. But I can't find the base case to stop it. In addition, Both ascending() and fixedPoint() are void method. Anybody has idea? lol Took me 3 days... When I run my code then 6,5,4,3,2,1 5,6,4,3,2,1 4,5,6,3,2,1 3,4,5,6,2,1 2,3,4,5,6,1 1,2,3,4,5,6 1,2,3,4,5,6 1,2,3,4,5,6 1,2,3,4,5,6 1,2,3,4,5,6 infinite............. public class Flipper { public static void main(String[] args) { Flipper aFlipper = new Flipper(); List<Integer> content = Arrays.asList(6,5,4,3,2,1); ArrayList<Integer> l1 = new ArrayList<Integer>(content); ArrayList<Integer> l2 = new ArrayList<Integer>(); // empty list aFlipper.fixedPoint(l2,l1); System.out.println("fix l1 is "+l1); System.out.println("fix l2 is "+l2); } public void fixedPoint(ArrayList<Integer> list1, ArrayList<Integer> list2) { // data is in list2 ArrayList<Integer> temp1 = new ArrayList<Integer>(); // empty list if (temp1.equals(list2)) { System.out.println("found!!!"); } else { ascending(list2, list1); // data, null temp1 = list1; // store processed value System.out.println("st list1 is "+list1); System.out.println("st list2 is "+list2); } fixedPoint(list2, list1); // null, processed data }
