  - <defunct> processesI've got a problem with <defunct> (zombie) processes on Linux...
    
    I'm running child processes using Runtime.exec() and it usually goes well.
    But just sometimes (undefined sometimes), process finishes as defunct. Is
    there anything I can do about it? I suck out both inputStream and
    errorStream, check Process.exitValue(), but it stucks on Process.waitFor().
    I even try to suck these streams in separate threads, but it doesn't help.
    
    I had the idea to detect if the process has stucked, and then try from
    another thread to Process.destroy(), but it didn't help! Destroy does
    nothing, process is still defunct, and waitFor() blocks it again... There
    are no more methods in class Process to try, and I've already tried all the
    combinations of existing ones...
    
    Newsgroups and web are full of similar questions, but no answer. They all
    say that a process is zombie if it is finished, but parent process hasn't
    yet read the exit code. But I do read exitValue, and I also do
    Process.waitFor(). Can I consider this a bug in Java VM?
    
    Where could find the solution? Which direction should I go? I've been trying
    for months, but no results...
    
    Now, this is the latest version of code, as seen on java.sun.com...
    
    {
    ...
    Process process = Runtime.getRuntime().exec(commandLine);
    inputVacuum = new TextVacuum(process.getInputStream());
    errorVacuum = new TextVacuum(process.getErrorStream());
    
    process.waitFor();
    
    int exitValue = process.exitValue();
    ...
    }
    
    public class TextVacuum extends Thread {
    
    private BufferedReader reader;
    private StringBuffer buffer = new StringBuffer();
    
    ...
    
    public TextVacuum(InputStream inStream) {
    reader = new BufferedReader(new InputStreamReader(inStream));
    start();
    }
    
    public void run() {
    try {
    char[] cbuf = new char[4096];
    int numRead = reader.read(cbuf);
    while (numRead != -1) {
    buffer.append(new String(cbuf, 0, numRead));
    numRead = reader.read(cbuf);
    }
    }
    catch (IOException e) { }
    finally {
    try { reader.close(); }
    catch (IOException e) { }
    reader = null;
    }
    }
    
    ...
    }
    
    Thanks!

  - Why does this query take forever?For some reason, I have a rather large (to me) query, with numerous inner
    joins, accessing a remote server, and it is taking about twenty times longer
    than most queries to the same database.
    The query itself is built programmatically within my application, and
    example of which is below. I am hoping someone in the group may have some
    insight into why this query is so slow, suggesting perhaps a better
    structure for it, such that I can go back in and rewrite my code that
    creates such queries.
    
    Thanks in advance, Ike

  - AccessControlException
    The following is a snippet from a method in an applet RSSTree:
    private Document getOPMLFile(String OPMLFileName) {
    
    Document OPMLFile = null;
    
    try {
    
    URL u = new URL(getCodeBase(), OPMLFileName);
    
    try {
    
    BufferedReader br = new BufferedReader(new
    InputStreamReader(u.openStream()));
    
    if (br != null) {
    
    try {
    
    Builder parser = new Builder();
    
    OPMLFile = parser.build(br);
    
    }
    
    .
    .
    .
    
    This method is called out of RSSTree.start(). Document & Builder are
    classes in the open source XML processor com.nu.xom. I get the following
    error when parser.build(br) is executed:
    
    java.lang.ExceptionInInitializerError
    at RSSTree.getOPMLFile(RSSTree.java:63)
    at RSSTree.start(RSSTree.java:31)

    If I replace the bad line with a loop to read the the stream myself and
    write out the lines, I get the XML I expect.
    
    Without seeing the source for XOM can someone give me an idea as to why I
    have an access problem when going through XOM but don't when the applet
    reads directly?
    
    Thanks.

  - Get installed appHi,
    
    I want to write an app but I'm not sure if I should use Java.

  - Can we change enctype dynamically??Hello all,
    
    Can we change enctype in the form tag using javascript
    document.formname.enctype = 'variable' variable being
    multipart/form-data or application/x-www-form-urlencoded. I can do
    this in Netscape7 not in IE6 ??
    
    My problem is when I am in the rendered page of type
    mulipart/form-data, I have to call another servlet (which process
    regular form fields only). When I do that it breaks.
    
    If I use all my servlets to process enctype=mulipart/form-data jsp's
    is there any performance or any kind of issues???
    
    Any help will be appreciated.
    
    Thanks - gsr

  - Learning Apache Ant, problems with Swing(?)I'm attempting to learn Apache Ant (apache-ant-1.6.1); OS Linux Fedora
    Core 2; j2sdk1.4.2_04. I appear to have problems with Ant + Swing, but
    each work separately.
    
    The following is my first build file (copied from the web).
    
    <?xml version="1.0"?>
    
    
    <project name="tutorial" default="build" basedir=".">
    <target name="build">
    <javac srcdir="." />
    </target>
    </project>
    
    Works fine on a simple Java program, e.g.
    
    import java.io.*;
    public class Hello {
    
    public static void main(String args[]) {
    System.out.println("Hello");
    }
    }
    
    However, when I progress to anything involving Java Swing, I get
    compilation errors like:
    
    [javac] /home/jc/java/classes/anttest/GuiScreens.java: In method
    `GuiScreens.main(java.lang.String[])':
    [javac] /home/jc/java/classes/anttest/GuiScreens.java:24: error:
    Can't find constructor
    `javax.swing.JFrame(Ljava/lang/String;Ljava/awt/GraphicsConfiguration;)'
    in type `javax.swing.JFrame'.
    [javac] frame[j][i] = new JFrame("Config: " + i,
    gc[i]);
    
    /This program compiles okay using javac./
    
    (BTW jc@localhost~/java/classes/anttest>$ echo $ANT_HOME
    /usr/apache-ant-1.6.1
    jc@localhost~/java/classes/anttest>$ echo $JAVA_HOME
    /usr/java/j2sdk1.4.2_04)
    
    Any ideas?
    
    TIA,

  - optimizing java compilerHi!
    
    As the -O option of javac does nothing and Sun obviously think it can affort
    not to do so, which compiler is known to optimize bytecode well? Jikes?
    eclipse? What about AspectJ?
    
    Regards

  - Midlet TextBox-------------------
    TextBox tb = new TextBox("title", null, 5, TextField.DECIMAL);
    tb.addCommand(new Command("Ok", Command.BACK, 0));
    tb.setCommandListener(this);
    
    Display dis = Display.getDisplay(this);
    dis.setCurrent(tb);
    -------------------
    
    The code above shows (in my mobile Sony Ericsson K300i) a TextBox with 2
    Commands "Ok" and "Ok".
    
    If TextBox is empty of chars, first "Ok" is grayed but second not.
    
    I suspect that the first Command "Ok" is part of TextBox (Screen) and
    when I press it, it does nothing and commandAction method does not run.
    Only when I press the second Command "Ok" commandAction method runs.
    
    So, first "Ok" is "feature" of my mobile or it is in MIDP Specification?
    If the second, how can I get access to this Command?

  - Vowel Counter ProgramHey,
    
    I am trying to write a basic program that counts how many lowercase
    vowels and non-vowels are in a string. I'm trying to use the
    StringTokenizer function. Also, I have to prompt the user again by
    using a do while loop. The string ends with the string "DONE".
    Here's my code. If anyone could help me, please do. Thanks.
    
    import cs1.Keyboard;
    import java.util.StringTokenizer;
    
    class vowelCounter;
    {
    public static void main(String[] args)
    {
    // Initialize Answer to Zero
    int answer = 1;
    
    do // Start the do loop
    {
    
    // Declare all variables and set counters to zero
    int aCounter = 0;
    int eCounter = 0;
    int iCounter = 0;
    int oCounter = 0;
    int uCounter = 0;
    int nonVowelCounter = 0;
    
    String line, temp;
    int letter;
    
    StringTokenizer tokenizer;
    
    // Prompt the user for String and read string
    System.out.print ("Please enter text (Type DONE to quit):
    ");
    line = Keyboard.readString();
    
    while (!line.equals("DONE"))
    {
    tokenizer = new StringTokenizer (line);
    while (tokenizer.hasMoreTokens())
    {
    temp = tokenizer.nextToken();
    letter = temp.length();
    
    for (int i=0; i<=letter; i++)
    {
    // Increment vowel counters
    if (line.charAt(i) == 'a')
    aCounter++;
    
    else if (line.charAt(i) == 'e')
    eCounter++;
    
    else if (line.charAt(i) == 'i')
    iCounter++;
    
    else if (line.charAt(i) == 'o')

    else if (line.charAt(i) == 'u')
    uCounter++;
    
    else
    nonVowelCounter++;
    }
    
    }
    line = Keyboard.readString();
    
    }
    
    // Print out number of vowels and non-vowels
    System.out.println ("Number of 'a': " +aCounter);
    System.out.println ("Number of 'e': " +eCounter);
    System.out.println ("Number of 'i': " +iCounter);

    // Prompt the User About Continuing
    System.out.print ("Do you want to continue?

    answer = Keyboard.readInt();
    System.out.println ("");
    
    }while (answer == 1);
    }

  - Open Source quality better then closed?hi...
    
    i just wondered, does the fact you write a product as open source,
    forces you to write better code, in the hopes (fears?) that who ever
    may see you code in the future will be impressed (shocked?)

  - illegalMonitorStateExceptionhello everybody!
    
    it is well known that one has to be in the monitor of an object to call
    myObj.wait(), f. E. by putting it into a synchronize(myObj) block.
    
    my questions:
    - is it bad programming style to just catch the exception without doing
    the synchronize? because if i do this my program still perfectly does
    what it should.
    - why does this exception exist?

  - Reading data from a file using AntHi Everyone,
    
    Im new to Ant and I am encountering some problems.
    I have a text file which contains a value in there. I need that value
    to be set into another file.
    I tried using Javascript but Javascript does not support I/O for files.
    Is there any command in Ant that can read a value from a text file (
    eg. output.txt ) and then use that value to replace into another file (
    eg. jsp ).
    
    Thanks,
    Marvin

  - Instant dragging from JTreeHi NG,
    
    I cannot drag an unselected element of a JTree. First I have to select
    it, then I can drag it. Is there a way to implement that? I think I can
    spare that extra click.
    
    Best regards, Christoph

  - Corrupted JPEG: DataInput/OutputStreamHi!
    
    I download a JPG and write it to disk; this is rather old code which
    certainly worked. The only thing I'm aware of that changed is JDK 1.4 ->
    1.5b2. The written file is corrupt:
    
    URL u = new URL ("http://foo/bar.jpg");
    DataInputStream in = new DataInputStream
    (u.openConnection().getInputStream());
    
    File f = new File (foo);
    FileOutputStream fs = new FileOutputStream (f);
    DataOutputStream out = new DataOutputStream (fs);
    
    for (int b; (b = in.read ()) != -1;)
    {
    out.write (b);
    }
    
    in.close();
    fs.close();
    out.close();
    
    What's wrong? And, can I repair the corrupt files?

  - java with swinghello to all,
    
    I have done a java component in Swing
    I have included the java component as plugin and
    embedded in applet for web based access. But it is not
    visible in other clients.
    It is visible in Only the server.
    I read javaweb start's JNLP can do that (since I
    didnot want to install anything jre like in client )
    is it possible.
    
    thank you in advance,
    vishnu.

  - Creating MouseEventsHi,
    I'm trying to dispatch interaction with a touch screen as a MouseEvent, but
    I can't get java to register an event on components like the drop-down list
    from a combo box, or invisble components that accept normal mouse click
    events.
    
    Thanks,

  - getting starting with ...... Java
    
    I am newbie of sorts: I'm familiar with java to a some extent, but I have
    never had the chance to use it. Which means, I'm not as comfortable with
    it as I am with other languages (php,asp,python,c,perl,etc). What is the
    best way to get comfortable? Is there any particular direction I should be
    heading? I never read a book from start to end, unless it's a novel, so
    with other programming languages I've learnt the fundamentals, and the
    bits and pieces here and there as needed. Database connectivity, web
    (server based) apps are of interest as most work I do is related to these.
    
    Current projects include pulling stats from a database (Postgres,mysql) in
    python and, a web credit card payment system in php. Im also maintaining
    one of our "legacy" systems in perl.
    
    I have lots of time, and I want use doing something productive in java,
    that is my aim.
    
    Directions will be helpfull....

  - jsp:setProperty, java.io.File, and I thoroughly confusedHi,
    I'm writing a webapp based on JSP technology. I've been doing
    some reading and from what I've read, it isn't possible to use
    jsp:setProperty to set a File property. So, I created a BeanInfo class
    for the Bean I had the File variable in. I also created a class that
    extended PropertyEditorSupport to assign the BeanInfo class to the
    Bean. But, those don't appear to get called. I CAN, however with
    Tomcat 5.0.28 on Windows XP, simply set a File property with
    jsp:setProperty. The Bean ends up looking for the file in the Tomcat
    bin directory, and I can thus set a relative path to the file. So, I'm
    completely confused. What is going on? Is this expected behavior?
    
    Thanks,
