  - .ear files in Sun Java StudioHi all,
    
    I am not sure if this is the right newsgroup for this question. But I just
    thought that some of you may be able to help me out; that's why I am asking
    you all this question.
    
    I have a .ear file and I just downloaded Sun Java Studio Enterprise 8. May
    I ask how can I import this .ear file in Sun Java Studio Enterprise 8? Can
    someone point me to the right direction?
    
    Thanks in advance,
    Monte

  - TCP client application does detect network failureHi,
    
    This is a behavior of the TCP socket in Java I dont' understand:.
    Let say we have a simple client/server application running on TWO different
    machines.
    The client send bytes to the server.
    The server recieved the bytes and wait for about X sec.
    During this waiting time, we disconnect the server from the network (just by
    unplugging the server network cable).
    After the waiting time the server is aware of the network failure (a
    SocketException is thrown : connection reset, because it is trying to send
    the response)
    But on the client side it is still stuck on a "rcv =
    commandInput.readLine();" statement (see after for the complete code), it
    will never be aware of the network failure !!! Even after one hour the
    client is still waiting to read something on closed socket. Is this the
    normal behavior ?
    
    In reality we are dealing with an application that use the FTP server to
    server mode (we are controlling only the command socket, the data transfer
    is made by the servers). We have to transfer huge file, thus we can not set
    up a time out. If the last scenario occurs, some of our transfers are stuck
    and it is not possible for us to detect the failure. The client will wait
    for ever the response.
    
    Does anybody have already deal with that ?
    
    Below is the simple client and server I made in order to make my experiment.
    The client just read the keyboard input and send it to the server; the
    server just echo the request except if the request
    is 'wait X', in this case it will wait for X sec before responding.
    
    Thanks by advance,

  - EJB: removing local TOsHi!
    
    This applies to WebLogic 7 but probably is generally the case.
    
    I have a Collection of Local objects which I want to remove(). So I thought
    collection.clear() would be sufficient and the container would do the job.
    But it doesn't.
    
    So, I iterate thru the Collection and call remove() on each Local object.
    This throws a ConcurrentModificationException because the container does
    remove the element from the Collection when calling remove() on the Local
    object.
    
    The only solution seems to iterate over the collection, put the objects to
    be deleted in another collection, iterating over that collection and
    calling remove() there on any Local object.
    
    Well, there must be something I misunderstood about EJB, right?

  - sending a message from jboss to all java-clientsHi
    
    I'm building a j2ee Application on top of j2ee and JBoss 4.0.
    The Clients connected to JBoss are non-web Swing Clients.
    
    If One Clients changes the data on a bean/in the db, all the other clients
    connected to the jboss have to be informed about the change, so they can
    update der UI.
    On a standalone Java-App i would use listeners to solve this, but as im new
    to j2ee i have no idea how to realize this with j2ee and jboss.
    
    It would be great to get some ideas on how to solve this problem.

  - Xdoclet JBossHi all,
    
    I am new to xdoclet and would like to convert my existing EJB source
    files to xdoclet embedded tags and ultimately generating deploy
    descriptors for JBoss.(4.0)
    
    My current application server is Pramati and i am migrating to
    JBoss(4.04GA) using xdoclet(1.2.3) as the EJB (Spec 2.0) deployment
    automation tool. I have the ejb.jar and other descriptors which are
    specific to Pramati Application server. I would like to generate the
    appropriate interfaces (Remote, Home etc) and JBoss specific
    descriptors for each EJB. I goggled but didnt find a complete example
    using xdoclet. The information seems to be scattered.
    
    I would like to know the steps for the following ( For eg I have a
    MyXYZBean.java )
    
    1) Adding appropriate xdoclet tags(Jboss specific) to this source file
    (MyXYZBean.java)
    2) Steps to generate the Remote, home etc interface source files ( Eg
    MyXYZRemote.java, MyXYZHome.java etc)
    3) Steps to generate JBoss specific descriptors (jboss.xml, ejb.jar
    etc)
    4) A task to be included in my build.xml which takes care of steps 1) ,
    2) and 3) appropriately.
    
    Many thanks,
    Santosh

  - What is the difference between a BMP EntityBean and a DAO ?As I read in a couple of articles a BMP (Bean Managed Persistence is an EntityBean
    where the programmer has to care about the SQL statements.
    On the other side a DAO implements the direct access to an SQL database.
    
    But isn't that the same?
    What are the differences ?

  - Designation standard output as File type I have a method (fragment below) that takes a File type "outFile"
    as the output file. However, if the user of this method specifies
    "null" for that parameter, I want to make the output go to standard
    output instead of a file.
    
    My question: To what do I set outFile (File type) to make the
    output go to standard output (display)? System.out is of a type
    PrintStream.
    
    Thanks, Alan

    Hi there,
    
    I've been looking at the JLint port (java/jlint). This port is flagged
    as BROKEN in FreeBSD 5.x. Looking at the JLint homepage I see that
    version 3.0 is current (the port is 2.3). I have easily managed to
    compile and install JLint 3.0, only a minimal patch is required (to
    disable the bool->int mapping in types.hh). Would someone mind upgrading
    this port? I send an upgraded port with this email. Please have a look
    at it, comment it and check it in if you like.
    
    Best regards, Roman

  - How does one combine the Adapter and Factory design patterns in a memory efficient way?I'm using the adapter pattern, and I've got a factory to generate adapters
    for passed in adaptees. Let's call the class of the objects getting adapted
    "Foo", and the Adapter class itself "Bar".
    
    So here are some details specific to my situation:
    
    1) the constructor for Bar is private and visible to the factory (Bar is
    acting as its own factory), so I can completely control when and how Bar
    gets instantiated.
    2) If an existing adapter for a given instance of Foo doesn't exist yet,
    I'll want to create a new Bar which matches with it.
    3) If there already is a adapter h for Foo, I have to return that existing
    match, and NOT generate a new one.
    4) upon a request for an adapter for null, I return null.
    
    This is relatively easy to do if I have infinite memory. I just create a
    Map<Foo,Bar>, like so:
    
    <code>
    public class Bar {
    private final Foo f;
    
    private Bar(Foo f) {
    this.f = f;
    }
    
    private final static Map<Foo,Bar> mapping = new
    ConcurrentHashMap<Foo,Bar>();
    
    public static Bar make(Foo f) {
    if (impl == null) {
    return null;
    }
    synchronized (mapping) {
    if (!mapping.containsKey(f)) {
    mapping.put(f, new Bar(f));
    }
    Bar b = mapping.get(f);
    assert returnValue != null;
    return returnValue;
    }
    }
    
    public void newInterfaceWhichModifiesState() {
    this.f.oldInterfaceWhichModifiesState();
    }
    
    public int newInterfaceWhichGetsState() {
    return this.f.oldInterfaceWhichGetsState();
    }
    }
    </code>
    
    However, it's possible that the calling code is generating billions and
    billions of instances of Foo, and then throwing them away after their first
    use. My Map would prevent the garbage collector from being able to reclaim
    those instances. I can safely delete those "throwaway Foos" and their
    matches from my Map, because if there doesn't exist a reference to some
    instance of Foo anywhere else in the JVM, then it can't possibly ever occur
    that that instance will ever get passed into my make(Foo) method, in which
    case, I would never need to return its corresponding Bar.
    
    The two potential-solutions I looked at, Maps of WeakReferences and
    WeakHashMap, turned out not to satisfy my requirements.
    
    If instead of a Map<Foo,Bar>, I had a Map<Foo,WeakReference<Bar>>, then it's
    possible that the matching Bar would get garbage collected, but the instance
    of Foo would get passed in again, and there's no way for me to recover its
    matching pair, thus violating condition (3) mentioned above.
    
    If I replace Map<Foo,Bar> with WeakHashMap<Foo,Bar>, none of the keys will
    get GCed, because instances of Bar contain a strong reference to Foo, via
    the private field f. If I change that field to a weak reference, then it's
    possible the instance of Foo that's being adapted will get GCed while the
    corresponding adapter is still in use, resulting in the newInterface()
    method failing.
    
    I think what I need is some sort of special PairOfWeakReference class such
    that if there are any references to either an instance of Foo or its
    corresponding Bar, then BOTH remain uncollectable. However, once there do
    not exist any strong references to either instances, then the pair become
    collectable simultaneously.
    
    Using a pair class, as in:
    
    <code>
    public class Pair<A,B> {
    public final A a;
    public final B b;
    
    public Pair(A a, B b) {
    this.a = a;
    this.b = b;
    }
    }
    </code>
    
    WeakReference<Pair<Foo,Bar>> won't work either, because the WeakReference
    class is checking against references to instances of the Pair class, rather
    than references to the instances of Foo and Bar.
    
    This adapter-factory combination doesn't sound like something that unusual
    or obscure, so I figure I must be missing something simple from effectively
    implementing it. Can anyone tell me what that is?

java-programmer, Java Swing font anti-aliasing w/o desktop environment Hello all,

With the newer versions of Java your Swing apps can look extra pretty
thanks to font smoothing. When using Ubuntu (as I am) the builtin
desktop environment configurations set this up for you - when running
GNOME, KDE, or XFCE it looks great. But I choose to run my .xsession
file instead, which loads FVWM. And somewhere along the line something
isn't set right and I don't get pretty smoothed fonts in my Swing apps.
I checked environment variables and I can't see it there, so I'm
thinking it may be an X resource? I don't know; if anybody has any
ideas on which knob I can twiddle to get the pretty fonts back, I'd
greatly appreciate it!

Best regards.

Thought I would post this here as well, seeing as it is probably more
of a GUI question than generalised Java.

Kind regards,

  - Java NIO selector close idle connections?I have an object attached to all selectionKeys with a timestamp
    showing last activity
    on the connection. So how/when do i run through the keys to find
    connections
    that have been idle too long? Can i do it in the same main selector
    loop that handles accept/read etc like this:
    
    while (true) {
    
    selector.select(sometimeout);
    Iterator selectedKeys = selector.selectedKeys().iterator();
    while (selectedKeys.hasNext()) {
    ..process the selected key... accept/read etc..
    }
    
    if (timeToCheckForIdleConnections) {
    Set<SelectionKey> k = selector.keys();
    .. get attachment of all keys and check their timestamp for last
    activity.. if idle for too long then close them!
    }
    
    }
    
    or should I use a timethread that signals back to the main selector
    thread which connections to close?

  - showdocument() problem (or bug?)I have a trusted applet that is supposed to generate a pdf file and
    save it as a temporary file on the local machine, then display it.
    Since display of such an animal can only happen with showDocument(URL,
    type) I am trying to build the url using :
    URL url = new URL("file:" + File.separator + File.separator +
    "filename.pdf");
    
    and this does indeed work IFF I run the applet locally. However, if the
    bloody thing is running connected to the server, it does not. Then the
    only command that works is
    URL url = new URL(getCodeBase(), "filename.pdf");
    so I had to bytestream the pdf down to server, have it install it in a
    file and make the call. A real waste, considering I'm supposed to be
    writing non-polluting software. Any ideas as to what's wrong with this?
    Thanks.

  - How to place a window in the center of the screen ?I would like to open a window and to placed it at a certain position on a screen
    (e.g. in the center).
    
    How do I do this? My (simplified) current code looks like:
    
    public class testGBL extends JFrame implements ActionListener {
    JLabel lab1;
    ....
    JButton butBack;
    
    public testGBL() {

    GridBagLayout gridbag = new GridBagLayout();
    GridBagConstraints c = new GridBagConstraints();
    contentPane.setLayout(gridbag);
    
    c.fill = GridBagConstraints.HORIZONTAL;
    
    butBack = new JButton("Back");
    c.gridx = 0;
    c.gridy = 0;
    c.weightx = 1.0;

  - JFace getting startedHi
    
    I try to run a simple SWT/Jface example. I am running this from inside
    eclipse 3.2.0 and I have included the following in my classpath:
    swt.jar - Taken from swt-3.3M3-win32-win32-x86.zip
    jface.jar - Taken from program files\eclipse\plugins and Renamed from
    
    org.eclipse.jface_3.2.0.I20060605-1400.jar
    
    Here is the class:
    
    import org.eclipse.jface.window.*;
    import org.eclipse.swt.widgets.*;
    
    public class MyJFaceExample1 extends Window {
    
    public MyJFaceExample1() {
    // super(null); //Wont compile with null as the beginner example says
    it should
    super(new Shell()); //Compiles
    }
    
    public static void main(String[] args) {
    MyJFaceExample1 demo = new MyJFaceExample1();
    demo.setBlockOnOpen(true);
    demo.open();
    Display.getCurrent().dispose();
    }
    
    ------------------------------------------------------------
    
    This compiles fine but when I try to run this I get:
    java.lang.NoClassDefFoundError:
    org/eclipse/core/commands/common/EventManager
    
    I then copy c:\program
    files\eclipse\plugins\org.eclipse.core.commands_3.2.0.I20060605-1400.jar
    and rename it to core.jar.
    
    I then get the following error: java.lang.NoClassDefFoundError:
    org/eclipse/core/runtime/ListenerList
    
    Then I am stuck.
    
    Please help me with getting started with JFace.

  - using ClassDep to reduce rt.jari have been trying to use the JINI tool ClassDep to create a list of the
    dependencies of a program i have written, but have been unsuccessful. when
    i run it i output a list of classes that ClassDeps says my program needs,
    but when i create an rt.jar file containing only those classes (yes, in the
    appropriate package directories) i get the following:
    NoClassDefFoundError: java.lang.ArrayStoreException.
    
    i figured maybe it was a fluke, and just manually included the class.
    after doing so i got the following, more confusing error:
    error: java.lang.Error: java.io.UnsupportedEncodingException: Cp1252
    
    Cp1252 is not something i specifically make reference to in my program, and
    have only a nebulous idea of what it even is/does.
    
    anyway, though, that's beside the point: i would really like to make a
    slimmed down version of rt.jar to fit my specific needs according to the
    classes that are needed by my app.
    
    is there any way to do this that works, or am i just using ClassDep
    incorrectly?
    
    Please Help!
    Thank You!

  - xmlencoder/decoder persistence delegateHi,
    I am using the xmlencoder/decoder classes to save objects, some of
    which do not have no-argument constructors. I understand that one could
    use something like:
    
    String[] prop = {"param1", "param2"};
    MyEncoder.setPersistenceDelegate(MyClass.class
    new DefaultPersistenceDelegate(prop);
    
    My question is, what if one has a class like:
    class A{
    -----
    B objB = new B(C c, D d);
    -----
    }
    
    class B{
    -----
    E objE = new E(F f, G g);
    -----
    }
    
    I need to save an object of A that contains an object of B that does
    not have a default constructor and B in turn needs to store an object
    of E which again does not have a default constructor. Assuming that all
    attributes of all classes that need to be saved do have the required
    setter and getter methods, I couldn't find a way to save all those
    objects because I can set the persistence delegate for only one class.
    Is it possible to save all the objects?
    TIA.

  - Clarification of JavaLive delegates criticism?Back when the new J2SE1.5 features were announced, there was a
    JavaLive community chat
    (http://java.sun.com/developer/community/chat/JavaLive/2003/jl0729.html)
    in which Neal Gafter explains the Sun stance on lack of support for
    delegates:
    
    ... There are serious semantic problems with trying to add delegates
    to a language in a consistent way. The main problem is that once you
    call the delegate, the original class instance is no longer part of
    the call chain, so overriding in the original class no longer takes
    precedence over the delegate. ...
    
    Could someone please explain this to me a little more fully? It
    sounds like he's saying that delegates cannot follow a subclass call
    chain if they are created from an object stored in a superclass
    reference, but I can't tell if he means overriding delegates
    themselves. I would like to know:
    1) What exactly does he mean in less ambiguous terms? (Or maybe just
    simpler terms; it's been a while since my college programming
    languages course.)
    2) What an example of delegates 'failing' like this would look like.
    3) What is so significant about this problem.
    
    I am already familiar with the 'Truth about Delegates' dialogue
    between Sun and MS and the lack of true type safety of C# delegates,
    but not understanding this criticism bothers me. Any help would be
    greatly appreciated.
    
    Thanks,

  - Compile error help (linking a class library)Hi,
    
    I set the CLASSPATH correctly but still get the following compile error. I
    also tried the "-classpath" alternative and get the same error message.
    
    /home/yao/eh/jython-20.class(org/python/core/PyInteger.java):4:
    class PyInteger is public, should be declared in a file named
    PyInteger.java
    (source unavailable)
    
    But the class PyInteger is in a file PyInteger.java, just it is in the
    class jython-20.class but no a .java source file. I use to do things like
    this (linking with a class library and use the classes provided in it) a
    lol before. But why this time, it's not working? Did I missing something?
    
    Thanks,

  - Non-text based source code. I don't have much to add above what's said at the blog entry, so I'll
    just link to it:
    http://www.realityinteractive.com/rgrzywinski/archives/cat_ideas.html
    
    It's not a particularly novel idea (Roedy has mentioned it often in this
    newsgroup, for example; calls it "SCID" I believe), but it's interesting
    because (assuming those screenshots weren't doctored), it looks like we'll
    be seeing IDEs with practical support for non-text based source code in the
    near future (on the order of single-digit years?)

  - &# in PARAM NAME causing problemsHello,
    
    I have an application that generates a HTML document that contains an
    applet. It places raw data into the PARAM NAME tag. Well, once in a blue
    moon it places the numeric character reference &# into the data. When my
    Java applet imports this using the getParameter command, it reacts
    differently between different version of IE. One solution is to not let my
    original application generate the sequence &#, however, this does not fix
    the HTML documents that have already been generated in the past. It would be
    nice to just fix the Java applet so it can import this raw data without
    having to recognize &# as a numeric character reference.
    
    Is this possible?
    
    Here is my HTML code:
    
    <CENTER><APPLET CODE="graphics.class" ALIGN=RIGHT HEIGHT=420 WIDTH=220>

  - JTable refresh problemI have a JTable where I paint some of the cell backgrounds with
    a custom renderer. getTableCellRendererComponent() paints with
    drawLine() and fillRect() and that sort of thing. It's all working
    fine but when I drag another window over the JTable, or when I
    scroll it, sometimes it's not getting repainted correctly.
    Any ideas how to make it refresh or repaint itself at the right
    times?
    
    I looked in the group archives and there were a lot of other messages
    but they were about when a table's content changes dynamically.
    I'm not changing the content, I'm just trying to get the table
    to keep the correct content when scrolled and when other windows
    pass over it.
    
    Thanks in advance,

  - dynamic instanciation of a generic classHi,
    
    I've a question about Tiger (Java 5), genercity and dynamic instanciation
    of class.
    
    I can't found tutorial or sample via the Net.
    
    By exemple :
    
    public class A<T>
    {
    private T v;
    
    public A(T v)
    {
    this.v=v;
    }
    
    public void test()
    {
    System.out.println(v.getClass().getName());
    }
    }
    
    I'd like instanciate the A class with something like that : Class.forName
    ("A").... but why can I specified T parameter ?
    
    Please, send me some sample or URL.
    
    Thanks,
