  - How do I receive SOAP Messages via HTTP from an App?Hi,
    
    I have a Java Application. It is both a socket server and a socket
    client. I can run the app on multiple computers and they can connect to
    each other.
    
    I can create SOAPMessages and use a SOAPConnection to send these
    messages to listening sockets on the other computers.
    
    I'm having trouble taking the received SOAP message as a byte stream
    and converting it to a Java SOAPMessage.
    
    How should I do this?
    
    I think I need an HTTP Server. Is this correct? Is there one included
    in the J2SE or J2EE classes?
    
    Thanks!

  - A similar problemHi,
    I get a similar stack except that the exception is a ServletException.
    I can't figure this out at all. Here's the field validation declaration
    that I am trying to use.
    
    <field property="clientaPlannedRetirementAge" depends="validwhen"
    page="1">
    <arg position="0"
    key="lnra.clienta.clientaPlannedRetirementAge"/>
    <var>
    <var-name>test</var-name>
    <var-value>(clientaExpectedAgeAtDeath >90)</var-value>
    </var>
    
    </field>
    
    Does anyone have any clues as to what this might be?
    Thanks

  - Any Source Code or Web site demonstrate the effect of gridwidth and gridheigh of GridBaglayoutDear all,
    
    I want to make clear how the outlook of Gridbaglayout will
    change according to different value of gridwidth and gridheight of
    GridBagConstraints. Please suggest some source code for me so that I
    can modify the source code of the value of gridheight and gridwidth,
    thus I can find out the change of the outlook according to different
    value of gridheight and gridwidth. Or please suggest some website for
    me to investigate about the gridwidth and gridheight of
    GridBagConstraints.
    
    Thanks.

  - MQ Series messages browse and deleteHi,
    
    I am writing an MQ client that should get messages from MQ Queue one
    by one and then delete it in case of successful processing.
    As documented in MQ Series Programming Guide a queue should be opened
    for browsing and removing. For browsing an option
    MQGMO_BROWSE_FIRST or MQGMO_BROWSE_NEXT should be used and for
    deleting MQGMO_BROWSE_MSG_UNDER_CURSOR.
    Browsing works fine for me but delete does not - all messages remain
    in a queue.
    
    Thanks
    
    Following is a code fragment:
    
    .................
    try {
    mQMgr = new MQQueueManager(remoteQManager);
    int openInputOptions = MQC.MQOO_FAIL_IF_QUIESCING |

    outputQueue=mQMgr.accessQueue(remoteQueue, openInputOptions);
    MQMessage retrievedMessage = new MQMessage();
    MQGetMessageOptions gmo=new MQGetMessageOptions();
    gmo.options=MQC.MQGMO_WAIT | MQC.MQGMO_BROWSE_FIRST;

  - Accessing a method inside of an object that is stored in a vector...I have been trying to post to .help all day but nothing is going
    through. Will try it here and hope it does....
    
    I am trying to access a getData() method that simply returns a stored
    integer value from an object that is stored in a vector. I have tried
    to do this but cannot get the notation correct. I tried google groups
    and the only thing I got from there was to pull the object from the
    vector into a temperary object. That didnt work.
    
    So, here is the code I have so far of making the temp object and
    making sure it is actually pulling one out. I still connot figure out
    how to access the getData() method.
    
    Any hints are appreciated.
    
    import java.util.Vector;
    
    public class StackUser
    {
    
    public static void main(String argv[])
    {
    
    Vector vector = new Vector();
    
    for (int i = 0; i < 100; i++)
    vector.add(i, new StackNode());
    
    System.out.println(vector.get(0));
    
    Object tobj = vector.get(0);
    
    System.out.println(tobj);
    
    }
    }
    
    public class StackNode
    {
    
    private int value = 0;
    
    public StackNode()
    {
    value = (int)(Math.random());
    }
    
    public int getData()
    {
    return value;
    }

  - Kill a thread automaticallyHi,
    
    If I have a class that runs a thread and no reference points to it, the
    gc won't finalize the class because the thread is still running -> so
    stopping the thread in the finalize() method won't work. Afaik this is
    also true for daemon threads.
    
    Is it possible to stop a thread automatically when there are no
    references left? In my case it does not matter if the thread is
    gracefully interrupted or just killed and whiped out.
    
    greets,

    Do I need this type? It does not seem to be in the junit.jar file.

  - Tomcat can't find antRun scriptI've been developing a web site on XP and deploying it on Unix (Solaris)
    using
    Tomcat 4.0.6 on the Unix box.
    
    In the last deployment of my class files, I also moved some jar files to
    $TOMCAT/common/lib
    and made some changed to server.xml to implemnet connection pooling.
    
    Now Tomcat won't compile a JSP page giving the message:
    Cannot locate antRun script: property 'ant.home' not found.
    
    I can't figure out what I broke. Can anyone tell me where this
    ant.home property should be set and and/or where antRun should
    live? I (believe) I have restored the server.xml and jar files to their
    originals but I still have the problem.
    
    I appreciate your help in getting me un-stuck.

  - How to convert int/float etc into byte[]?For example
    
    int i = 2;
    char c = 'c';
    float f = (float)3.45;
    double d = 3.546;
    String s = "Hello";
    
    I want to write all these into a binary file.
    
    In OutputStream, PrintStream classes
    they have
    
    write(int byte); and
    write(byte[] buffer, int offset, int length);
    
    My question is how do I convert those i,c,f,d,s into
    byte[]?

  - dynamic file download with *long* response time - How to show "Save As" early?I've got a Java servlet that delivers large database resultsets
    transformed to Excel with the HSSF library. In some cases it takes
    more than 15 minutes before transformation is done and content can be
    delivered to the browser.
    
    I want to show the "Save As" dialog as early as possible so the user
    knows he's not lost and forgotten.
    
    I already tried to send the response headers immediately after
    receiving the request including content disposition and filename. Even
    though the browser receives those headers it just won't trigger the
    "Save As" dialog. This applies to both MS IE and Mozilla.
    
    Any ideas appreciated.

    It looks like a Properties object is what you need. You could do

    Properties props = new Properties();

    I am trying to create a ssh/telnet client as a Java application.
    I am new to network programming but I have gathered some tutorials

  - using soap/java/perl or some such to search the web ?This is what I'd like to do for a project if possible,
    I've read a little bit that various search engines and other tools
    through
    soap or something give you hooks into web search capabilities.
    
    I want to search womens profiles on yahoo personals, possibly I will
    mark some of those profiles based on the pictures. This part would be
    partially manual through an interface I might design. After that I
    would want to run those
    marked personal profiles through some other code. I'm thinking this
    code might have to decode the actual html a bit. What it would do is
    look for certain keywords and then generate a customized reply to that
    personal ad based on common interests and so on, or mark certain ads
    as highly relevant based on keywords. For instance if a girl had
    camping listed in her profile, my response letter might include
    something about how I like camping, I have a truck camper and so on.
    But if it did not find any keywords, it would not make as much of a
    mention camping in the generated response letter. Once I have
    generated response letters, I would have some sort of manual process
    where I have to go and type in the coded thingamajigs they generate.
    
    I'm not sure how hard all this would be or how high level/low level I
    want to go with it or where to start, though I am an experienced C++
    programmer, have done java/perl and so on. I think yahoo uses java
    script. I have seen books on java script, using perl for this sort of
    thing as well.
    
    Any thoughs appreciated.

  - High performance file creationHi everyone
    
    I have a servlet that queries a database, processes the ResultSet,
    turns it into a n String[][] and sends it by Serialization into an
    applet that contains basically a JTable to display the contents to the
    user.
    Now, somewhere in the middle of this, a StringBuffer is filled with
    the contents of the String[][] so an CSV file can be created on the
    server for the final user to download. The ideia is to display the
    data on the applet and manipulate it on the Excel sheet.
    But... the applet updates the JTable with the table faster than the
    file can be written on the server, so when the link is shown on the
    webpage the file hasn't been created and when the user tries to save
    it, it returns an error.
    
    Is there a way for me to create the file faster than the applet is
    created?
    
    Thank you very much

  - tcpmon loggingHi all,
    
    I find the tcpmon utility from apache.org very useful. But is there
    any way to make the tcpmon to log the http request + response into
    local file instead of just displaying at the GUI, so it is easier for
    me to trace later?
    
    Thank you.
    
    Best regards,

  - FreeBSD Java porting project questionsHi all.
    I have some questions about this freebsd port.
    1)Why we need linux jdk, when building a native distr?
    Is that necesarily to build compiler with classes semultaneusly?
    2)What are you think about java (and of course jdk) future on freebsd.
    I saw freebsdfoundations last message dated last year, and nothing more.
    Doesnt project stop or going to?
    
    Thanks for all answers. I really interesting about this

  - Ant testing jar for differences
    Hi,
    
    I'm trying to implement this logic in an Ant build script:
    
    1) Put all .class files into a new tempLatestBuild.jar
    2) If HASH(tempLatestBuild.jar) != HASH(
    previousLatestBuild.jar) replace...
    
    I've done this with web.xml and various other config files,
    but jars change everytime (even though the .class and MANIFEST.MF file
    do not).
    
    With the <jar> task, the MANIFEST.MF timestamp was different
    every time in the resultant jar.... So I changed it to a <zip> task
    and copied in the MANIFEST.MF by hand.
    
    This fixed the timestamp issue, but there are still two bytes
    difference, and I can't see what they are. All the flags on the files
    look ok (examined in winzip and when unzipped).
    
    Has anyone done this kind of thing?
    
    Cheers,

    valve (as per the instructions) I got the following error upon
    starting up Tomcat. Does anyone know why???

  - Java symbol confusionHi there,
    
    I started learning myself java a while ago and there's still loads of
    concepts and things about the java language i don't know, so i may just
    make an arse of myself now...
    
    I use the NetBeans 5.0 IDE to play around with. Sometimes it does
    things that I think (from what I've learned about java) that it
    shouldn't do. I may just be stupid or something, so could somebody
    point out my faults. Here's a piece of code:
    
    import java.net.*;
    import java.io.*;
    
    public class Main {
    
    public static void main(String[] args) {
    
    try {
    ServerSocket serverSocket = new ServerSocket(56);
    
    }catch (IOException e) {System.out.println("Daar was kak in die
    konneksie...");}
    
    Socket clientSocket = null;
    <<------------------------------------
    clientSocket = serverSocket.accept();
    <<------------------------------------
    }
    }
    
    Ok that's just part of it. I'm still learning how to do the rest. Ok,
    my first problem here is that when the two lines marked with arrows
    above is out of the try-catch block, NetBeans tells me it can't find
    the symbol serverSocket. On the other hand, when I put the two marked
    lines inside of the try-catch block, it works without a problem. Can
    someone explain to me why this is happening??
    
    ===========WORKING=============
    try {
    ServerSocket serverSocket = new ServerSocket(56);
    Socket clientSocket = null;
    clientSocket = serverSocket.accept();
    }catch (IOException e) {System.out.println("Daar was kak in die
    konneksie...");}
    
    ===========NOT WORKING=============
    
    try {
    ServerSocket serverSocket = new ServerSocket(56);
    }catch (IOException e) {System.out.println("Daar was kak in die
    konneksie...");}
    Socket clientSocket = null;
    clientSocket = serverSocket.accept();
    
    It says:
    
    C:\Documents and
    Settings\Constant\netServer\src\netserver\Main.java:22: cannot find
    symbol
    symbol : variable serverSocket

  - "standards" for tooltips?All,
    
    I'm working on a large Swing app. which has inconsistent use of
    tooltips. In fact I have to address a bug report complaining about the
    inconsistencies of the tooltips. Some of our widgets display "helpful
    text" as tooltips, others display the full details on the chosen value
    (e.g. full pathname of a file chosen) etc.
    
    Is there any documented standard for how best to use tooltips?
    
    TIA,
    Sean
