  • all individual panels are not shown inside root panel

    - by Suresh Kumar
    Respected sir/madam, I want to add multiple jpanels to jpanel.So i added a root panel to jscrollpane.and then added all individual jpanels to this root panel.I made jscrollpane's scrolling policy as needed.i.e HORIZONTAL_SCROLLBAR_AS_NEEDED,VERTICAL_SCROLLBAR_AS_NEEDED. But the problem is all individual panels are not shown inside root panel. Code: JScrollPane scPanel=new JScrollPane(); JPanel rootPanel=new JPanel(); rootPanel.setLayout(new FlowLayout()); JPanel indPanel = new JPanel(); rootPanel.add(indPanel); JPanel indPanel2 = new JPanel(); rootPanel.add(indPanel2); //.....like this added indPanals to rootPanel. scPanel.setViewPortView(rootPanel); //scPanel.setHorizontalScrollPolicy(HORIZONTAL_SCROLLBAR_AS_NEEDED); And one more thing is, as i scroll the scrollbar the panels are going out of jscrollpane area. I am not able to see all individual panels, Please suggest me.

  • Can I use XText for a DSL involving an XML file type?

    - by Chris
    I have defined a small DSL that is mostly written in the form of different types of XML files in conjuction with some property files. This works very well but I wish to create an Eclipse Editor to make editing these files easier for beginners (I already have a working parser). The main XML file can reference some items from the .properties files and vice-versa. THe main xml file can also reference other XML files. Certain options should only be available in the main xml file based on the contents of the .properties files and based on some osgi plugins that can be added to the DSL project (the syntax is dynamic depending on context). The structure of the language is fixed but the options available in each attribute or the choice of attributes themselves changes depending on metadata contained in plugin .jar files. Questions: Does XText support dynamic syntax (validation changes depending on external factors)? Does XText support XML files / .properties files? Thank you very much for your help in advance.

  • Postgresql 8.4 reading OID style BLOBs with Hibernate

    - by peter
    I am getting this weird case when querying Postgres 8.4 for some records with Blobs (of type OIDs) with Hibernate. The query does return all right but when my code wants to read the content of the BLOB with the simple code below, it gets 0 bytes back public static byte[] readBlob(Blob blob) throws Exception { InputStream is = null; try { is = blob.getBinaryStream(); return org.apache.commons.io.IOUtils.toByteArray(is); } finally { if (is != null) try { is.close(); } catch(Exception e) {} } } Funny think is that I am getting this behavior only since I've started adding more then one such records to the table. The underlying JDBC library is type 3 (postgresq 8.4-701). Can someone give me a hint as to how to solve this issue? Thanks Peter

  • Android: Context menu doesn't show up for ListView with members defined by LinearLayout?

    - by RandomEngy
    I've got a ListActivity and ListView and I've bound some data to it. The data shows up fine, and I've also registered a context menu for the view. When I display the list items as just a simple TextView, it works fine: <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/nametext" android:layout_width="wrap_content" android:layout_height="wrap_content"/> However when I try something a bit more complex, like show the name and a CheckBox, the menu never shows up: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/nametext" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <CheckBox android:id="@+id/namecheckbox" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> Can long-presses work on more complex elements? I'm building on 2.1.

  • Why static fields are not initialized in time?

    - by Tom Brito
    Somebody tell me: class MyClass { private static MyClass myClass = new MyClass(); private static final Object obj = new Object(); public MyClass() { System.out.println(obj); // will print null once } } I wonder, isn't this a bug? Why static objects are not initialized before the constructor runs?

  • Problem with detecting the value of the drop down list on the server (servlet) side

    - by Harry Pham
    Client code is pretty simple: <form action="DDServlet" method="post"> <input type="text" name="customerText"> <select id="customer"> <option name="customerOption" value="3"> Tom </option> <option name="customerOption" value="2"> Harry </option> </select> <input type="submit" value="send"> </form> Here is the code on the Servlet Enumeration paramNames = request.getParameterNames(); while(paramNames.hasMoreElements()){ String paramName = (String)paramNames.nextElement(); //get the next element System.out.println(paramName); } When I print out, I only see, customerText, but not customerOption. Any idea why guys? What I hope is, if I select Tom in my option, once I submit, on my servlet I should able to do this: String paramValues[] = request.getParameterValues(paramName); and get back value of 3

  • migrating an embedded jetty server from v6 to v7

    - by Ceilingfish
    Hi chaps, I have an embedded servlet which I use in unit tests, looks like this: public class UnitTestWebservices extends AbstractHandler { private Server server; private Map<Route,String> data = new HashMap<Route,String>(); public UnitTestWebservices(int port) throws Exception { server = new Server(port); server.setHandler(this); server.start(); } public void handle(String url, HttpServletRequest request, HttpServletResponse response, int arg3) throws IOException, ServletException { final Route route = Route.valueOf(request.getMethod(), url); final String content = data.get(route); if(content != null) { final ServletOutputStream stream = response.getOutputStream(); stream.print(content); stream.flush(); stream.close(); } else { response.sendError(HttpServletResponse.SC_NOT_FOUND); } } .... } That's written using version 6.1.24 of Jetty. I tried switching over to use Jetty 7.1.1.v20100517, and updated that code to this: public class UnitTestWebservices extends AbstractHandler { private Server server; private Map<Route,String> data = new HashMap<Route,String>(); public UnitTestWebservices(int port) throws Exception { server = new Server(port); server.setHandler(this); server.start(); } public void handle(String url, Request request, HttpServletRequest servletRequest, HttpServletResponse response) throws IOException, ServletException { final Route route = Route.valueOf(request.getMethod(), url); final String content = data.get(route); request.setHandled(true); response.setContentType("application/json"); if(content != null) { response.setStatus(HttpServletResponse.SC_OK); final Writer stream = response.getWriter(); stream.append(content); } else { response.sendError(HttpServletResponse.SC_NOT_FOUND); } } } But whenever I tried to access make a request to the server it would hang indefinitely. Has anyone experienced anything similar?. It also printed this into the log: log4j:WARN No appenders could be found for logger (org.eclipse.jetty.util.log). log4j:WARN Please initialize the log4j system properly. org.eclipse.jetty.server.Server@670655dd STOPPED +-UnitTestWebservices@50ef5502 started

  • What reasons have people had to write their own classloader

    - by montyontherun
    I was recently asked in an interview about the order in which classloaders are called when a class is loaded. Unfortunately I've never had the need to write my own classloader so at the time was unfamiliar with the intricacies of classloading. This got me wondering, what reasons are their to write your own classloader. So that's my question: What scenarios have people faced which required the need to writing their own classloaders?

  • How to display a two column ListView in Android?

    - by Josemalive
    Hi, I have an android application that shows a grid view that shows: 1 2 3 4 GridView gridview=(GridView)findViewById(R.id.GridView_test); DataBaseHelper dbhelper=new DataBaseHelper(this); ArrayList<String> test=new ArrayList<String>(5); backlinksadapter.add("1"); backlinksadapter.add("2"); backlinksadapter.add("3"); backlinksadapter.add("4"); ArrayAdapter mAdapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, test); gridview.setAdapter(mAdapter); By the moment is working, but i would like to show foreach line of the grid, 2 columns with the values of a 2 dimensional array (something like the GridView in ASP.Net - as datasource -). I would like to show: 1 | Person 1 2 | Person 2 3 | Person 3 4 | Person 4 Any idea?

  • In Jetty, can NCSARequestLog be configured to auto-detect the time zone?

    - by David Moles
    It looks as though in 2003 or so NCSARequestLog would pick up the system time zone using TimeZone.getDefault().getID(), but in more recent versions it seems as though it's hard-coded to GMT, unless you override it in jetty.xml or programmatically. If true, this kind of annoying, since it means if you don't want GMT logging you have to edit jetty.xml for every installation (not to mention twice a year for daylight saving time). Is there a workaround that will let Jetty pick the time zone up from the system?

  • Alternative Control Structures

    - by Brock Woolf
    I've been wondering about alternative ways to write control structures. One that you learn early on for if statements is a replacement for this: if ( x ) { // true } else { // false } with this (sometimes this is more readable compared to lots of brackets): x ? true : false It got me thinking. Can we replace anything else incase it's more readable. We of course replace if statements like this: if (a < b) { return true; } else { return false; } with things like this: return a < b; We can save a long if with something like this (pretty much same as the one above): bool xCollisionTrue = (object.xPos < aabb.maxX && object.xPos > aabb.minX); So those are the ones I can think of off the top of my head for the if statement and doing comparisons. So I'm wondering what about looping constructs, for, while, etc. Maybe the code obfuscators might have some ideas.

  • add jsf project facet in eclipse/ why need it?

    - by user384706
    Hi, I started on JSF2.0. I followed a tutorial with no problem and all worked fine! I used Eclipse Helios. But I noticed something I can not understand. The tutorial said to add Project Facet for JSF 2. I did no such thing and all worked ok. So to follow tutorial exactly I did: Right-click on Project -Properties- Project Facets And JavaServer Faces check-box was not ticked. I assume this is what the tutorial means by Project Facet. I clicked on it and a Further Configuration Needed link appeared. I followed the link to a JSF capabilities (Modify Faceted Project) dialog, I selected as User library, my library of JSF(which is MyFaces) but I got the error message: Found multiple versions of the required class javax.faces.FactoryFinder. What is this error? Can't I add project facet after creating my project? And what do I need the project facet for? My (trivial) code indicates that JSF works ok, so what is the project Facet useful for? Thanks!

  • JFileChooser - multiple file filters?

    - by waitinforatrain
    Hi guys, I have a question about the JFileChooser in Swing. I'm trying to get multiple file extensions in the drop-down box, but have no idea how to do it. There is the method extFilter = FileNameExtensionFilter(description, extensions); that I can then use by writing fileChooser.setFileFilter(extFilter); however, as you can see, this only supports one option in the drop-down list. How do I add more?
