  - database connection pooling in tomcat 3.3.1Hi,
    I have a webapp which uses database connection pooling setup just like
    the tomcat how-to suggests. But, I can't seem to get it to work on
    tomcat 3.3.1. I couldn't even find any how-tos or guidances on it
    anywhere. Is it supported ?
    I get a javax.naming.NoInitialContextException: error when I set it up
    in the conf/app-myapps.xml like the 3.3.1 doco suggests.
    Appreciate any help on this.
    Regards,
    Lenine

  - GridBagLayout and JMenuBar problemsHere's another interesting one. I looked on the Bug Parade to see if
    this was present, but rapidly drowned in the sea of totally unrelated
    results I got back from the brain dead search capabilities.
    
    I built up a JPanel using GridBagLayout and various components. Works
    fine; I'm quite used to GridBagLayout and its quirks. I'm using the
    Java look and feel with native decorations turned off, so GridBagLayout
    respects my panel's minimum size constraints.
    
    I had been testing this layout in a JFrame without a JMenuBar, just to
    validate the layout. Now when I added a JMenuBar to the JFrame, the
    layout screws up when I resize the panel down to its smallest size.
    It's as though the GridBagLayout does not take the JMenuBar's dimensions
    into account when resizing happens. In my case, a couple of buttons
    shrink in height, a text field bizarrely grows to 1.5X height, and
    another text field overlaps it. None of these problems show up unless
    the menu bar is in place.
    
    Again: a known bug? Or should I submit it?
    
    If there's any interest I'll whittle my code down to a SSCCE. Then I'll
    try it with native window decorations turned on to see if that's where
    the problem lies.

  - Baffling class not found problemHello, I'm using Java 1.3 with WebLogic 5.1 on Solaris. I have these
    files:
    
    cms/system/CMSException.class
    cms/system/Constants.class
    cms/system/InitServlet.class
    cms/system/Log.class
    
    When I include this line on my JSP page
    
    <%@ page import="cms.system.*" %>
    
    everything compiles fine. As does this line
    
    <%@ page import="cms.*" %>
    
    but when I try
    
    <%@ page import="cms.system.Constants" %>
    
    (r using any of the 4 class names above) I get the error:
    
    Compilation of '/tmp/support/jsp_servlet/_www/__temp.java' failed:
    /tmp/support/jsp_servlet/_www/__temp.java:16: Class
    cms.system.Constants not found in import.
    probably occurred due to an error in /www/temp.jsp line 1:
    <%@ page import="cms.system.Constants" %>
    
    How can this be? The perms on the files above are all 775. Can anyone
    think of an explanation for why these files can't be found?
    
    Thanks, - Dave

  - J2ME, How to minimize a program ?Thank you so much for the information I didn't know.
    
    But, for Sony Ericsson cells, we can press back button ( like the
    symbol of inverse Enter ) to exit ( not destroy ) program.
    
    For SmartPhone - P910i, we can run other funtion very easily ( we don't
    have to implement it )
    
    I found a cheat method that could do this.
    
    public Form f;
    ....
    ....
    // Do not new a Form for f
    
    display.setCurrent(f); // minimum program :p
    
    // I don't know why, the compiler pass it, and we can find it is work
    on cell.

    You never said...
    
    Did your original code call one of the applets methods from JavaScript?
    
    ...or was it something else?
    
    I'm just curious to what was wrong...

  - 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?

  - Whatever happened to PvdL?My curiosity about Hotjava now sated, what of Peter van der Liden? I recall
    that he used to be pretty active on Usenet and quite a prolific author and
    Java advocate.
    
    As I recall he used to author the Java FAQ (which now 404's). I liked his
    writing style (dating to the ugly fish book) and the Just Java series. The
    6th edition came out in 2004 and no errata has published since January
    2005.
    
    Is Mr. van der Liden still active in the Java community? I realize he's no
    longer with Sun and without treading into personal matters, did he have a
    falling out with the people there? In spite of being published by Sun, his
    Java books did contain quite a few barbs about misfeatures in the language.

  - jsp servlet code seperation confusionI posted this on the .help NG but I believe you folks could probably
    provide more of an accurate answer considering the help group is
    targeted towards true beginners.
    
    Okay, where I am employeed I have the options of programming with
    Microsoft Technologies and Java specifically J2EE. I have been
    investigating the task of learning Java for about the last 3 to 4
    months. I am a ASP.Net developer fulltime at work with C#. I was new to
    OOP when I started into .Net about a year ago and am getting better.
    However, our corporation uses Java as a National standard and I am
    looking to advance some day and need to learn Java. Furthermore, where I
    live, KY there are very few jobs for technologies other than .Net and
    Java. No PHP or ColdFusion.
    
    In the last couple of years this code seperation theory has overloaded
    the programming world. .Net does it with what's called code behind. In
    my research of Java the only things I see that reference code seperation
    is servlets (I am sure J2EE and EJB contribute also). However,
    everything I have read on servlets reference outputing HTML back to the
    browser via the HttpServletResponse and Request objects.
    
    My question, why in the world do they consider outputting HTML back to a
    browser via a servlet considered code seperation. Furthermore, it
    seems very time consuming and difficult to hand code complex layouts in
    HTML and incorporate/format it for a servlet.
    
    Can someone please explain or direct me to a resource where I can
    understand why using servlets at any point in an application would be
    better than jsp or even applets? Sometimes it's hard enough to design
    complex layouts with the assistance Dreamweaver for example.
    
    Thanks for any insight you can provide, I have read hundreds of pages of
    information concerning this and trying to compare it with the my current
    knowledge in the .Net world.

  - JSP questionshave some questions about JavaServer Pages to ask
    
    1. I made several input fields for user to input the height, width and
    other stuff to create a table. how can I make the font in color red in
    first row and first column automaticly and font in other rows and
    columns remain the same color?
    
    2. I want to add a title inside the table that need to colspan the
    rest of the table. Becasue I don't know what # the user will input for
    columns, so I can't set it before user input. so plz help me on this.
    
    3. Randomly place an input field in one of the cells ?a different
    cell on each refresh. If the user enters the correct product there and
    changes the focus (by clicking outside the field), a Javascript
    provided by the jsp page checks the answer and makes appropriate alert
    
    My jsp file looks like this:
    
    <HTML>
    <head></head>
    <BODY>
    
    <%
    String s2 = request.getParameter("Bsize") ;
    s2 = s2.trim();
    out.print("<table bgcolor=silver border= ");
    out.print(s2);
    out.print(" ");
    String s3 = request.getParameter("Bcolor") ;
    s3 = s3.trim();
    out.print("bordercolor= ");
    out.print(s3);
    out.print(">");
    
    String m1 = request.getParameter("mName") ;
    m1 = m1.trim();
    int M = Integer.parseInt(m1);
    
    String n1 = request.getParameter("nName") ;
    n1 = n1.trim();
    int N = Integer.parseInt(n1);
    
    String s = request.getParameter("FullName") ;
    s = s.trim();
    out.println("<font color=red size=6>");
    out.println(s);
    out.println("'s table is: </font>");
    
    out.println("<tr colspan= ");
    
    out.print(m1);
    
    out.println(">");
    out.print("<th> Numbers </th> </tr>");
    
    for (int i =1; i<= M; i++ )
    {
    out.println("<tr width= 10 >");
    
    for (int j =1; j<= N; j++ )
    {
    out.println("<th >");
    out.println(j * i);
    out.println("</th>");
    }
    
    out.println("</tr>");

    Uh no, because those leave control with the language. Most people who
    defend the goto so vehemently,are, with modern languages like Java,
    simply are using it to emulate something else available within the language.
    
    Let's see, in the last 10 years, I have written about 1,000,000 lines of
    C code, the number of actual goto's in there, none. During that time, I
    viewed probably 40,000,000 more lines, which contained maybe 20 gotos.
    Shows how little goto is actually needed. Of those 5, were code that
    was complex trying to do something simple, usually the reason I was
    looking at it, was because it wasn't working (poor design). Five more
    were instances where you had the jack-of-all-procedures, where the
    programmer had written a bunch of procedures in one block of code (again
    poor design). They used goto to make the thing work. The remaining
    ones, were places where the programmer had written themselves into a
    corner, and under pressure of getting the thing to work, used goto to
    bail out (again poor design).

  - For loop not working from static methodI have a JSP that outputs 10 links and it works great but want to cut
    down on the scriptlet lines in my JSP.
    Now I want to put the for loop that outputs the 10 links into a source
    file and call the class in my JSP using just one line scriptlet.
    
    Here is what my current JSP looks like where it outputs the 10 links:
    
    <jsp:useBean id="pageinfo" class="storm.Pageinfo" scope="session" />
    .....
    <%
    if (pageinfo!=null)
    {
    for(int i=0;i < 10;i++)
    {
    out.println("<a href=moveto.jsp?inpage=" + i + ">" + i + "</
    a>");
    }
    }
    
    %>
    
    Now my attempt to put it in a class outputs only 1 link instead of 10.
    
    Source code for the Java class:
    
    package storm;
    import storm.*;
    
    public class PageUtil
    {
    public static String theMethod(Pageinfo pageinfo)
    {
    if (pageinfo!=null)
    {
    for(int i=0;i < 10;i++)
    {
    return "<a href=moveto.jsp?inpage=" + i + ">" + i +
    "</a>";
    }
    }
    return "";
    }
    }
    
    JSP scriptlet calling the static method:
    
    <%= PageUtil.theMethod(pageinfo) %>
    
    Please advise how I can get this to work. I am using Tomcat 4.1.27
    and dont have JSTL.

  - Grab common name from https://[ip]Hello,
    
    I checked around on here a bit, and was unable to find an answer to
    this one by searching for the error message. I'm hoping someone here
    can help me with this issue.
    
    I am attempting to gather the common name from an SSL certificate for a
    given IP address. Following is the code I am using thus far (two
    classes being used):
    
    IP_Justification.java:
    
    import java.net.*; //for https connection
    import java.io.*; //for input parsing
    import javax.net.ssl.HttpsURLConnection;
    
    public class IP_Justification
    {
    private String IP; //IP address to search
    private String domain; //common name returned by viewing IP via
    https://ip
    
    //default constructor
    public IP_Justification()
    {
    throw new IllegalArgumentException("Please provide IP and domain");
    }
    
    //create with IP provided
    public IP_Justification(String ip)
    {
    IP = ip;
    domain = "";
    }
    
    public void getDomain() throws IOException
    {
    String urlToCheck = "https://" + IP;
    URL techURL = new URL(urlToCheck);
    System.out.println("URL created: " + techURL);
    
    HttpURLConnection techUrlConn =
    (HttpURLConnection)techURL.openConnection();
    System.out.println("HttpURLConnection created" + techUrlConn + "\n");
    techUrlConn.connect();
    }
    }
    
    IPJustMain.java
    import java.io.*;
    
    public class IPJustMain
    {
    public static void main(String[] args) throws IOException
    {
    
    IP_Justification testing;
    testing = new IP_Justification("64.233.167.99");
    testing.getDomain();
    try
    {
    
    }
    catch(Exception e)
    {
    System.out.println("Start of output - Exception block");
    System.out.println(e.getMessage());
    System.out.println("End of output - Exception block");
    }
    }
    }
    
    Following is the output received when running IPJustMain:

    Press any key to continue . . .
    
    I fully expect to have an exception thrown, and am hoping to be able to
    parse that for the information I require. The problem I am running
    into is the exception itself:
    
    Exception in thread "main" java.io.IOException: HTTPS hostname wrong:
    should be
    <64.233.167.99>
    
    It seems to be responding with the URL I pass to it, and not the common
    name for the SSL at the specified IP address.
    
    Anyone happen to know if there is a way around this or if my code is
    flawed in someway?
    
    Thanks for any help that can be provided!

java-programmer, How to speed up the Portal development in eclipse Hi all,

I am new in portal development. I am used to Eclipse to write Java
standalone application, but no server contained application such as
servlet.

Is there any way to setup a integrated development environment with
JetSpeed in Eclipse to do portal environment?

Please enlighten me.

Thanks in advance for your inputs and ideas.

Bad translation?
Hmm, "not?", as in does not have experience writing servlets?

  - 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 java.util.StringTokenizer;
    
    class vowelCounter;
    {
    public static void main(String[] args)

    int answer = 1;
    
    do // Start the do loop
    {
    
    // Declare all variables and set counters to zero
    int aCounter = 0;
    int eCounter = 0;

  - <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!

  - 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?)

    As the -O option of javac does nothing and Sun obviously think it can affort

  - 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

  - 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,
    
    Jon C.

  - 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

    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.
    The app is a crossed platform.
    My questions:
    1.Can Java return me the name/position of install app on the OS it
    supports?
    2. Does Java supports the following OS:
    Unix/GTK+ , Unix/Motif and X11 , Mac OS , MGL and OS/2 ?
    
    TIA.

  - Sunspot: Java Virtual Machine Implementation Vulnerability``SUN Java Virtual Machine Implementation Vulnerability
    
    We have found a security vulnerability in the SUN's implementation of
    the Java Virtual Machine, which affects the following SDK and JRE
    releases:
    
    - SDK and JRE 1.4.1_03 and earlier
    - SDK and JRE 1.3.1_08 and earlier
    - SDK and JRE 1.2.2_015 and earlier.
    
    SUN was informed about this issue on June the 2nd 2003 and has already
    addressed it in their latest SDK/JRE versions. Please, see Sun Alert
    Notification numbered 57221 for more information about the patched
    SDK/JRE releases. [...]
    
    The described vulnerability allows for the creation of a malicious
    applet that could *completely* bypass applet sandbox restrictions. We
    developed proof of convept code which successfully exploited this
    vulnerability in Netscape 6 and 7 as well as Mozilla web browsers
    environment using vulnerable versions of JRE Plugin. [...]''
