  - How to get jsp and servlet interaction.I need some help/assistance from someone with this problem of mine of
    trying to get a jsp which displays a table with some table data in it,
    i.e., some of my favorite movies, to interact successfully with a
    servlet!!! Now, in the servlet, I have used--probably for the very 1st
    time ever--the servlet method "RequestDispatcher" and both of the
    getAttribute() and the setAttribute() methods, but alas, when I try to
    view the jsp in my web browser, I only get the jsp title showing!!! Now
    whasssssssssup with that anyway???!!
    
    Here is first my servlet code :
    
    /* Here is a particular servlet which is used with a jsp that will
    * print out a movie list.
    */
    
    import java.io.*;
    import java.util.*;
    import javax.servlet.*;
    import javax.servlet.http.*;
    
    public class MovieServlet extends HttpServlet {
    public void service (HttpServletRequest request, HttpServletResponse resp)
    throws IOException, ServletException {
    PrintWriter out = resp.getWriter();
    String [] movieList = { "Patton", "Some Like It Hot", "Bank
    Shot","Beyond Atlantis", "Titanic"};
    java.util.List mymovie = new java.util.ArrayList();
    mymovie.add(movieList);
    request.setAttribute("movieList", mymovie);
    String[] items = (String[]) request.getAttribute("movieList");
    for(int i = 0; i < items.length; i++){
    String movie = items[i];
    out.println(movie);
    }
    RequestDispatcher steve = request.getRequestDispatcher("mymovies.jsp");
    steve.forward(request, resp);
    }
    }
    
    and then my jsp code :
    
    <%@ taglib prefix = "c" uri="http://java.sun.com/jsp/jstl/core" %>
    <html><head>
    </head><body>
    <b><i>My Personal Movie List</b></i><br><br><br>
    
    <table>
    <c:forEach var = "movie" items = "${movieList}"varStatus =
    "movieLoopCount"> >
    <tr>
    <td>Count : ${movieLoopCount.count}</td>
    </tr>
    <tr>
    <td>${movie}</td>
    </tr>
    <tr><td>Patton</td></tr>
    
    </c:forEach>
    </table>
    </body></html>

  - Simple recursion / stack question
    Hi All,
    
    I suspect this is a bit of a 'how long is a piece of string' type question
    (the answer to which is of course precisely 2 x half its length) but I'm
    going to ask it anyway.....
    
    How deep is the java process stack? If I write some complicated piece of
    code that is recursive, how can I know if I will run out of stack doing the
    recursion or not?

  - How to determe JRE build using Java?Is there a way to determine the Java build from within Java?
    
    I can do so from the Windows command line using:
    java -version
    For the latest Sun JRE build I get:
    build 1.6.0-rc-b68
    
    However, using "java.version" inside a Java program all I get it:
    1.6.0-rc
    
    Is there some way to get the full information from inside Java?

  - WAIT CURSORHi ,
    
    I'm trying under a java/swing application to put a WAIT CURSOR when the
    system works.
    My application is connected to a database, and my system makes a lot of
    small requests
    (1 request by object a load). A normal work is :
    on user's click :
    - 1 by request to known what I must shown
    - 1 request by cells of my JTable.
    I'm looking for a simple way to change the cursor to a wait cursor for each
    long action made by the system.
    
    If someone could help me, it will be fine.
    
    thank's.

  - Why does a method act differently when invoked manually to when invoked through the driver class?Can anyone tell me why, when I run the driver class InstantiateFerry to read
    a file containing the test just below, this part of the code:
    ferry.getvehicleLocation(); produces the message Vehicle MVK806R is in lane
    1 and position 1, which I don't want, but when I enter the file details
    manually and invoke the method public void getvehicleLocation(), I get the
    message I want with correct values for lane and position rather than just 1
    and 1 every time?

  - auto-resizing applets?Say I have the following applet:
    
    import java.applet.*;
    import java.awt.*;
    
    public class Test extends Applet
    {
    public void start()
    {
    try
    {
    add(new Label(getParameter("echo")));
    }
    catch (Exception e)
    {
    e.printStackTrace();
    }
    }
    }
    
    Here's how I'm including it:
    
    <applet width="500" height="500" code="Test.class">
    <param name="echo" value="hello, world!" />
    </applet>
    
    The only problem with this method is that the width and height are
    fixed. Is there a way for the width and height to be exactly as big as
    they need to be to display the echo parameter, whatever it may be?
    
    Also, would it be possible to change the font of the Label? Or maybe
    make it so that you can highlight the Label's text just as you can
    normal html?

  - New tutorial web site http://progzoo.netI'm working on a web site to teach Java. http://progzoo.net/
    
    I think it is unique or at least unusual in that students can compile
    and execute their code from the text box - and find out immediately if
    they are right or wrong.
    
    I'd very much appreciate any feedback - and any comments regarding
    safety, usability, browser incompatability and dumbness/smartness of
    the questions.
    
    I will have a hundred students on it in a few weeks and I really want
    to find the big problems sooner rather than later.
    
    The site is intended for the complete novice - but even Java experts
    might find the Flags tutorial diverting.

  - Protected and package in iterfaceLew wrote in thread "Interface":
    > What maxnesler forgot to show is that the implementing class declares
    > the method to be 'public', which is implied automatically in the
    > interface declaration
    
    Why did the people writing the Java specs decide that an interface
    should not contain protected and package methods?
    
    I can imagine several cases where this would be useful.

  - Extracting c++ header from jar file using javahI'm trying to create a native header from an existing jar file
    (actually, only one class w/in the jar file). I've tried all sorts of
    command line arguments (w/ classpath) and nothing seems to work.
    
    Here's the setup:
    
    * package is blah.jar and contains dozens of classes, one of which I'm
    interested in creating a .h for (blahClass.java)
    * I have the source for it in another directory but its dependencies
    are pretty large and I figure using javah on the .jar file would be
    easiest?
    * why wouldn't this work:
    
    javah -classpath c:\temp\work\blah.jar blahClass
    
    blahClass is also part of a larger package (net.program.message) so I
    also tried:
    
    javah -classpath c:\temp\work\blah.jar net.program.message.blahClass
    
    nothing works.
    
    any ideas? thx

  - Import of large CSV datasets in JavaLike many other enterprise applications, in our application we need to
    export and import of large data in CSV format. As many people
    suggested in the newsgroups we may use native tools such as SQL*Loader
    for performance reasons.
    
    But in our application we have internally generated sequence number as
    PK. So we will not have luxury of using these tools directly.
    
    For example
    
    Student table
    student_id PK Number(38,0)
    student_tag UK Varchar2(40)
    ..
    
    Course table
    course_id PK Number(38,0)
    course_tag UK Varchar2(4)
    ..
    
    Student_Course table
    student_id
    course_id
    ..
    
    If we need to import student table, then we may have only student_tag
    and other info and we need to find student_id (using
    seq_student.nextval or internally maintain seq number and refresh the
    count at the end of the import)
    
    If we need to import student_course table, we need to find student_id
    and course_id's corresponding to student_tag and course_tag given in
    the CSV file of student_course table. This is where the performance
    problem lies.
    
    Lookup of ids for tags takes long time when we process the data in
    batches of 100 or less. One idea could be first fill in all the IDs in
    the tmp_student_course.csv file (copy of student_couese.csv but
    without TAGs) and then import using sql*Loader.
    
    Can any one suggest alternative design ideas or third party APIs to
    accomplish this? Any pointers will be greatly appreciated.
    
    thanks,
    Srinivas

    Hello, I don't think you understood me. I didn't seII it to her, so
    only after that did I list it on ebay. Not during the same time. I
    also don't like being threaten like that. If you had any problem with
    me, you didn't have to bld on the ltem. You decided to bld, so now you
    have to pay. You cannot threaten me to not take action. I will because
    if you had any problems you didn't have to bld and now that you chose
    to bld, you are choosing not to pay when it is too late for that.

  - Accessing MS sapi for speech controlled jukebox softwareHi,
    
    I'm developing speech-controlled jukebox software using the MS SAPI.
    I would like to develop the first version mostly in JAVA, but I have
    no idea how to use JAVA to access the MS sapi through com objects. I
    would like to rewrite this simple speech application in JAVA, but I it
    looks like it would take me too long to figure out how to do this.
    
    Here is the app:
    
    SAPI 5.0 Tutorial I: An Introduction to SAPI
    http://www.generation5.org/content/2001/sr00.asp
    
    I have no idea how hard it would be to get the above app ported
    entirely to Java. Given my experience it looks pretty hard. I know
    C++ pretty well, but I have not done much development for three years.
    I am also pretty new to JAVA. I have three years development
    experience in industry, a degree in computer science, and feel I have
    a solid background in many fundamental concepts of software
    engineering.
    
    I have also built, tested, and modified this app - IntelliMusic
    (http://www.generation5.org/content/2002/intellimusic.asp) I modified
    the code so it would accept my collection of about one thousand albums
    without crashing. I got about 99% accuracy using MS SDK 5.1, athlon
    2000, 1gb ram, and a high quality microphone. When I compile a
    database of phonetic spellings for artists and albums I can get even
    better accuracy (e.g. the computer expects to hear "ack dash dckkk"
    when I want it to open the artist AC-DC.) I need to be able to get
    this same accuracy with JAVA. I plan to sell my work and possibly
    open-source it later.
    
    I am now re-evaluating my software design. Earlier I planned to
    develop the speech module in c++ and the rest in JAVA.
    
    Thanks in advance for your suggestions.

  - JDK 1.5 and J2EE?I have bravely set up JDK 1.5 on one of my systems, which works a
    treat. The trouble I'm having is with using it for J2EE applications.
    I've tried dropping j2ee.jar into lib/ext so I can get at Servlet
    and so on, but then I get another problem...
    
    I use TransformerFactory.newInstance(), and I get a "class not found"
    exception for org.apache.whatever.Transformer (which JDK 1.4 used)
    rather than com.sun.org.apache.whatever (as per JDK 1.5). I presume
    that the TransformerFactory is coming from j2ee.jar rather than the
    1.5 library for this to happen...?
    
    So: I want to be able to rebuild (and improve!) a load of code using
    1.5, and I can do this for most things; servlets recompile fine, as
    do various other apps, but I seem to have a choice between leaving
    all my servlets on 1.4 (and removing j2ee.jar from 1.5) or leaving
    my XML stuff on 1.4 (which I don't want to do, because I want some

iText is good: A) The API is usable B) There are examples C) There is a
mailing list that gets good traffic.

All the best,

I was on two projects over the last year or so that used iText extensively.
The "PDF guy" in the projects was a moderately experienced Java programmer,
but not a Guru, and he had little to no trouble with it. He got beautiful
pages out with a minimum of effort.

This was in a Servlet/JSP environment where the PDFs were viewed through the
browser on the client side. It did not, however, involve converting graphics
to PDF.

That recommends the product to me.

  - IE7 hangs sporadically when running applets (with modal windows?)Hi.
    
    I have an applet which uses a FileDialog to retrieve reference to a
    file in the file system. This applet has worked without problems in
    earlier IE versions and other browsers, but occasionally under IE7 when
    closing the FileDialog, and effectively freezes the browser.
    
    The last few lines in the applet console:

    I've read about another user in comp.lang.java.programmer who has the
    same problem, and also with modal windows it appears. Has anyone had
    similar experiences?
    
    Thanks.

  - Socket : can i limit the applet bandwidth (data-transfer) client-to-server ?Hello ,
    I have builded ServerSide Socket with Java and ClientSocket still in Java
    (applet) .
    
    The Client send very amouth of data to server (1Mbyte, 3Mbyte) .
    Now , I need to limit the bandwidth that Applet client can transfer to
    server .
    
    Example :
    - 30 KByte/s
    - 50 KByte/s
    
    The client can't send more that 30KByte/s to server , example .
    In order to do this , I think that there are only one solution :
    
    1 - buffer the data in great byte[] array that store ALL data that client
    must send!
    2 - send the first 30KByte buffered
    3 - use Thread.sleep(1000)
    4 - send the NEXT 30KByte buffered
    5 - repet from [4]
    6 - byte[] array is totally send , finish...
    
    Before starting to write this , i want to ask if there are other solutions .
    Thanks a lot for any suggestions ...
    
    Best Regard,

  - jmf player skipping, do I need to start player within a thread?Hi
    I am having problems with media player. When there are other processes
    running in the background or foreground the jmf media player starts
    skipping and sounds terrible. Here is my code:
    
    private void createPlayer()
    {
    if(file == null)
    {
    System.out.println("file has null content");
    return;
    }
    removeOldPlayer();//remove earlier players
    try
    {
    //create a new player
    player = Manager.createPlayer(file.toURL());
    player.addControllerListener(this);//add listener to my player
    player.start();
    }
    
    catch(Exception e)
    {
    System.err.println("Error creating player, possible missing file");
    }
    
    The code works fine and plays the audio file with no problem, its only
    when my computer is doing other things that the player goes to pot.
    Should I be running the player in a thread? If so how do I do that, I
    have no experience with threads. Please help.
    
    Thanks

    For complex it is more important that the operators be exactly the same
    as those used for float and double. This is less valuable for other
    types like matrices and vectors. The reason is that many expressions on
    complex values are exactly the same (and have the same meaning) with the
    complex values replaced by real values.

  - byte[] -> TObject
    Function is receiving TObject as argument, but I have byte[], so I need something like this:
    
    somefunc(new String(abc.getBytes()));
    
    getBytes() returns byte[]. Is there some other class that would take byte[] in constructor? Something like: new Bytes(byte[]),
    because I can't use String class.
    
    Original code:
    
    MimeBodyPart attachment = new MimeBodyPart();
    attachement.setContent(abc.getBytes(), contentType);

  - FreeBSD - "Class.getClasses" problemI'm using Java 1.4.1, on FreeBSD 5.1.
    
    I have a problem where I'm attempting to use reflection to get a list
    of the classes that a given class extends. The problem is that the
    method call "Class.getClasses()" always returns an empty array, when
    it is called. I've tried it with a number of different classes, my
    own, and the standard API classes, always getting back the same
    result. The "Class.getDeclaredClasses()" also has the same problem.
    
    I used the following code to verify this behaviour:
    
    ////////////////////////////////
    Class[] aclassExtends = Class.forName(strClassName ).getClasses();
    for (int iClassIndex = 0; iClassIndex < aclassExtends.length;
    ++iClassIndex )
    {
    Class classExtend = aclassExtends[iClassIndex ];
    System.out.println("class:" + classExtend.getName() );
    }
    ////////////////////////////////
    
    This should output the names of all classes and interfaces that the
    given class extends and implements. It works on other OS (tested on
    OSX and Windows 2K), but not on FreeBSD.
    
    Has anybody else experienced this problem? If so, is there a patch or
    a workaround available?
    
    Any help would be appreciated.
    
    Thanks,
    Michael

  - Can Web Start reference resources other than jars?In the resources section of your jnlp file it appears you can only
