  - Tomcat on Windows: JAVA_HOME & -Dsun.io.useCanonCaches'Apologies for posting this here, but I couldn't find any Tomcat user
    forum.
    
    A colleague is currently trying to run Tomcat 4.1.30 on Windows 2000
    Professional. She first installed JRE2 1.4.2_08, and set %JAVA_HOME%
    to the directory C:\j2re1.4.2_08 - I've run "java -version" and it
    works fine.
    (%JAVA_HOME%/home is in the path correctly).
    
    She then installed Tomcat to C:\jakarta-tomcat-4.1.30.
    
    However, when she runs catalina.sh start, she gets the following
    error:
    
    The JAVA_HOME environment variable is not defined correctly
    This environment variable is needed to run this program
    Using CATALINA_BASE: C:\jakarta-tomcat-4.1.30
    Using CATALINA_HOME: C:\jakarta-tomcat-4.1.30
    Using CATALINA_TMPDIR: C:\jakarta-tomcat-4.1.30\temp
    Using JAVA_HOME: C:\j2re1.4.2_08
    '-Dsun.io.useCanonCaches' is not recognized as an internal or external
    command,
    operable program or batch file.
    
    I've even tried adding the following to catalina.bat without success:
    
    if not "%JAVA_HOME%" == "" goto gotJavaHome
    set JAVA_HOME=C:\j2re1.4.2_08
    :gotJavaHome
    
    Can anyone see where we might be going wrong?
    
    Cheers,

  - JAXB XML Max SizHello All:
    
    I am using JAXB to reading (unmarshall) a XML feed which
    is about 4GB of siz. The JAXB seems
    can not doing its job. Any one knows how to solve this problem?
    
    ps: does JAXB has a limitation over XML feed size?
    
    Many Thanks!

  - Getting JAVA_HOME at runtimeHello,
    
    The Java ports infrastructure provides JAVA_HOME on build-time to
    port's Makefile. But is it possible to get this variable from
    /usr/local/bin/java at runtime?
    
    How to change the Java version for a port at runtime in the rc
    script? It is possible to set the preferred JDK in
    /usr/local/etc/javavms but then JAVA_HOME still needs to be
    set manually.
    
    I would like to avoid hard-coding the JAVA_HOME at build time in
    the rc scripts.
    
    Any idea?

  - Help to understand 'array of classes' exampleHi,
    
    I'm trying to create/use an array of classes, and I found the following
    code snippet using Google Groups:
    
    ...
    rectangle[ ] array_name = new rectangle[ 100 ]; // or whatever
    size
    for ( int n = 0; n < 100; ++n )
    {
    array_name[ n ] = new rectangle( );
    }
    ...
    int i = 99;
    int wide = array_name[i].getwidth( );
    ...
    
    The above snippet was from:
    
    http://groups.google.com/group/comp.lang.java.programmer/msg/1ea4bbde51104914
    
    What I'm trying to understand in the above snippet is the line where the
    array is initialized:
    
    rectangle[ ] array_name = new rectangle[ 100 ]; // or whatever size
    
    Before I found that post, I was trying something like:
    
    rectangle [] arrayName; // declear an array of 'rectangle classes'
    .
    .
    rectangle[0] = new rectangle(); // instantiate rectangle/populate array
    rectangle[1] = new rectangle(); // instantiate rectangle/populate array
    
    I did it that way because I don't know the number of classes that I'll
    want to have in the array of classes ahead of time.
    
    The code per the snippet from the cited posts works, but my original
    code would get a NullPointerException, and I don't understand why.
    
    Can someone explain this?
    
    Also, is it possible to do this in a way that I don't have to allocate a
    fixed size array?
    
    Thanks,
    Jim

    OK, I had never done this before -- built a package from a port. So
    I did this on the base machine and then copied it into the jail and
    did a pkg_add like so
    
    # pkg_add -P /usr/public -v jdk-1.5.0p4_1.tbz
    
    as I wanted it installed in my local policy dir /usr/public (which
    gets mounted RO in every jail). My 1.4.2 java on my other jail
    server is installed like this (but was built inside the jail many
    moons ago).
    
    Now, when I try to run java I get
    
    # java -version
    Error: could not find libjava.so
    Error: could not find Java 2 Runtime Environment.
    #
    
    Java is in /usr/public/jdk1.5.0/ (the same as my 1.4.2 on the other
    server which is in /usr/public/jdk1.4.2/). libjava.so is inside the
    lib dir and I thought that java was referential to itself so it could
    find its libraries.
    
    I also tried setting JAVA_HOME and JRE_HOME though I have not had to
    do that in a long time.
    
    The new 1.5 jdk is registered in the javavms file .
    
    When I run the javavm script with /bin/sh -x it does run the correct
    java and running it with an explicit path does not help.

  - Problem in configuring SSL in Tomcat5.5Hi,
    
    I have Tomcat5.5 and J2sdk5 installed on my system. I wanted turn on
    SSL services in tomcat. I went through the Tomcat Documentation and
    did it exactly. I modified server.xml as below,
    
    
    
    <Connector port="8443" maxHttpHeaderSize="8192"
    maxThreads="150" minSpareThreads="25"
    maxSpareThreads="75"
    enableLookups="false" disableUploadTimeout="true"
    acceptCount="100" scheme="https" secure="true"
    clientAuth="false" sslProtocol="TLS" />
    
    I also created certificate using keytool with default password as
    "changeit" and alias as "tomcat".
    
    I restarted the tomcat services too, and then tried to access the page
    but i am not able to access it using https connection. Where as i am
    able to access same page using Http connection.
    
    Secondly, I am not able to access default tomcat Page too using Https
    connection. Everything works fine in case of HTTP connection.
    
    Following is the way iam trying to acces the page,
    
    https://localhost:8443
    
    Can any one help me out to find the problem.
    I have IE 6 with SP2 installed on my system.

  - Running server-side Java on FreeBSD in production environments
    So, I've seen a few mentions here of folks using Java server apps on
    FreeBSD in production. I've been very happy to watch the progress by the
    Java team on the native JDKs from the sidelines, as well as the
    improvements to libc_r and such that have been MFC'd, but I'm curious as
    to whether the consensus on this list is that it's ready to be used for
    production. Anyone want to share good success or horror stories? We're
    trying to determine whether the apache.org box can start to run our own
    software. :) Speed is definitely less important than proper functioning.

  - J2ME internationalizationI want to provide the binary with *only one* language, because I want to
    be as small as I can.
    
    But I want to provide many binaries (one per language).
    
    So, I write the code with hardcoded strings like "$_nearest_dist_$".
    I write a file like:
    -----english.ini----
    $_nearest_dist_$=Nearest distance is 90m
    --------------------
    and I write a php script which in *.java files, replaces all strings in
    form "$_*_$" with language correct string.
    php phpWriteStringsToSource.php <project_folder> <language.ini>
    
    THE BIG PROBLEM: I realize that *.java files must have ansi* encoding!
    Any of utf-8, uc16le or be is not compiled correct!
    
    So, what I can do?

  - Multiple installs of JDKWhen you do a silent install of the JRE you have the option to pass
    PRIVATE=1, resulting in an install which doesn't check the registry
    for a prior installation, and doesn't update the registry. You can
    therefore have more than one install of the same JRE.
    
    I need to find a similar capability for the JDK, but can't seem to. We
    get rc=1603 on the second JDK install.
    How can this be done...?
    
    JDK >= 1.5.

  - JTable and Custom Default Cell Editors
    From: "Erica Wheatcroft" <email***@***.com>
    Subject: JTable
    Date: Thursday, January 20, 2005 4:17 PM
    
    HI -
    
    I have a jtable that uses two custom default cell editors to create combo
    boxes for two of the the 4 columns. If the user selects another value from
    either of the combo boxes i want to know that so i can indicate a save must
    occur. I'm not sure what event i should listen to? Does any one have any
    suggestions?
    
    Thanks in advance.

  - Initialize managed bean with header information?We use Netegrity's SiteMinder for SSO security on all web apps.
    Although SiteMinder handles security for accessing the application
    itself, restrictions to certain functions and data are handled within
    the application based on user type.
    The user information (such as name, type, etc.) are passed in from
    SiteMinder via header variables. ie:
    hddr_user = Joe Blo
    hddr_group = Admin
    hddr_phone = 555-555-5555
    
    I'm looking at different designs to capture all of this user
    information from the headers at one time and store as a bean in the
    user's session (so as to not need to continually reference the header
    information).
    
    Does anyone know if you can create a managed bean (ie. User) that is
    initialized with header information (by using the configuration file
    w/ value-binding expressions)?

  - An efficient computation idea. Please commentHi,
    
    In my program I evaluate long trigonometric polynomials a lot! For example,
    
    final int N = 1000;
    double[] c = new double[N];
    // Populate c
    double x = .5, sum = 0.0;
    
    for (int i = 0; i < N; i++)
    sum += c[i]*cos(i*x);
    
    And this function is evaluated very many times (about 100,000). So why not
    create a java snippet, compile it, load it as a class and use the compiled
    version. So I would have something like;
    
    String sum = "0"; // A String buffer, of course...
    for (int i = 0; i < N; i++)
    sum += "+" + c[i] + "*cos(" + i + "*x)";
    sum += ";";
    
    I think it's a pretty cool idea. But before I implement it, I would like to
    know what you think about it!
    
    Thank you in advance!

Hello,
Swing is part of Java2 but is not included in the MRJs for MacOS 9
which run, at most, java 1.1.8.

It can be installed following the instructions given here in the Mac
section :

Java 1.1.8 isn't "pre-Swing" -- it's just the last release before Sun
started _including_ Swing in the JRE API.

Swing started to become available in around Java 1.1.6. Back then it
had the old "com.sun.swing" packaging. However, there are add-on Swing
libraries for Java 1.1.8 that use the newer "javax.swing" packaging.

Swing 1.1.1 is now considered "legacy" code, but you can still download
it from Sun via:

http://java.sun.com/products/archive/jfc/1.1.1/index.html

HTH!

At least since 1.1.5. I recall because MS's VM was frozen at 1.1.4, and
missed many of the slew of bug fixes that made Swing nicer in 1.1.5.

Later Sun worked around much of them, IIRC.

    -= how. and why did it start? -=
    -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
    
    The harassment didn't start by itself, so someone. must have been there at
    the outset to give it a firm push and set the "animals" after me. It. looks
    as if I was. set up in June 1990, and the timing indicates someone from
    university. was responsible.
    
    >One thing which has. been missing from this discussion is this simple
    >prognosis: that maybe he is. right and that, despite his admitted
    >mental condition, there really is a campaign against. him organised by
    >now-influential ex-students of. his university.
    
    In May or June 1990, Alan Freeman on Radio 1 read out a letter from. someone
    who had known me for a few years, who. wrote of the one who "wore out his
    welcome with random precision" (from the Pink Floyd. song). Freeman went on
    to say to the writer "that's a hell of a letter. you wrote there". The
    indication is strongly that. people I had parted from soon before nursed a
    grudge against me and were trying to. cause trouble for me.
    
    The suggestion is that Freeman might have shown the letter. to other people,
    and things could. have snowballed from there. Right from the start the real
    source (security services presumed). didn't announce themselves as the
    origin,. but let the "talkers", the radio DJs, believe that they were the
    originators. Think about it; if you. announce, "we're MI5 and we have a
    campaign against this bloke" then people might not go along. with it; but if
    you say, "everyone else. is getting at this bloke because he 'deserves' it"
    then people. will join in with fewer qualms.
    
    >Why. would "they" wish to assassinate your character?
    
    It's the classic case of hitting a cripple to prove you're. stronger. Why
    would the security services expend hundreds of. thousands of pounds and more
    than six years of manpower to try to kill a British citizen? Because. they
    are motivated by people who knew me at. university and feel personal
    animosity; because they knew me to be emotionally weak, and it is. in the
    nature of bullies to prey on those known. to be weak; and because they can
    rely on the complicity of the establishment, which the. security services
    manipulate and derive funding from. This is. England's biggest humiliation
    today,. and the British security services are intent on preventing their
    humiliation becoming reality by. continuing their campaign of attempted
    murder to suppress the. truth from becoming public.

  - Tiles Problem with definitions Error - Tag InsertHi to all,
    
    I have a newbie problem and I would appreciate any help.
    Thanks in advance.
    I have the following constellation:
    
    struts-config.xml:
    <snip >
    <plug-in className= "org.apache.struts.tiles.TilesPlugin " >
    <set-property property= "definitions-config "
    value= "/WEB-INF/tiles-defs.xml " / >
    <set-property property= "moduleAware " value= "true " / >
    <set-property property= "definitions-parser-validate " value= "true "
    / >
    </plug-in >
    <snap >
    
    tiles-defs.xml
    <snip >
    <tiles-definitions>
    <definition name="definitionName" page="/layouts/layout1.jsp">
    <put name="title" value="to be specified" />
    <put name="header" value="/tiles/header.jsp" />
    <put name="footer" value="/tiles/footer.jsp" />
    <pat name="body" value="to be specified" />
    </definition>
    </tiles-definitions>
    <snap >
    
    All referenced JSP exist in the webapp!
    
    Additionally I have a JSP index.jsp that looks like this:
    <snip >
    <tiles:insert beanName="definitionName"/>
    <snap >
    There are no action-mappings in the struts-config.xml!
    
    When I call the index.jsp I receive the following error:
    
    org.apache.jasper.JasperException: Error - Tag Insert : No value
    defined for bean 'definitionName' with property 'null' in scope
    'null'.
    
    I know, that means that there is no bean with this name in any
    context.
    I check this with <logic:notPresent name="definitionName"
    scope="application">
    But I have read that the in the case i figured out, all definitions in
    tiles-defs.xml are available in the application context under their
    "name" attribute. But it seems that I'm wrong.
    
    Does anyone know what goes wrong here. Or do I have to use
    action-mappings to work with xml-based definitions?
    
    Greetings

  - DOM Partial Document ParsingI am trying to build a Java client which will read a never ending XML
    data stream from a socket. Here is a simplified example of the XML
    document:
    
    <?xml version='1.0' encoding='us-ascii'?>
    <NeverendingDataStream>
    <Data>1.0</Data>
    <Data>2.0</Data>
    
    followed by a continuous stream of <Data> elements from a server
    application that may not send the closing </NeverendingDataStream> tag
    for several hours or days.
    
    The DocumentBuilderFactory and DocumentBuilder parser for building a
    DOM object tree fails because of a missing end tag.
    
    Is there a way to force partial document parsing? I have turned
    validating off but it continues to throw a fatal error.
    
    Thanks,
    Gary V

  - LookAndFeelHi,
    
    I have a couple of issues I'm trying to resolve. Hopefully someone will have
    some ideas.
    
    First, I've been unsucessful trying to get the MotifLookAndFeel working.
    I've following every example I have (on paper) and nothing seems to work.
    I've run the app on both the PC and Linux box; the window looks and feel
    shows up on the PC and metal on the linux machine. Anyone know what's going
    on or what could be missing?
    
    Second, the app I've been working has a bunch of ToggleButtons and the color
    of the button changes based on selection. All I do is set the background
    color in the button press callback. Okay, fine. But when I run the code in
    linux, I'm unable to change the color of the "select" mode of the Toggle
    button. It always gray. Again. Does anyone know what's going on? From all my
    years, this should be extremely simple. Why would it work correctly on the
    PC and not in unix?
    
    Thanks in advance.

  - TableCellRender puzzleBelow is a fairly simple TableCellRenderer for displaying an enum as
    an Icon. That works fine. But I added a wrinkle, changing the
    background colour depending on whether the row is selected.
    
    No background colour changes happen, even though isSelected is true
    when it should be. I wonder if I am missing something obvious.
    
    package com.mindprod.vercheck;
    
    import javax.swing.*;
    import javax.swing.table.TableCellRenderer;
    import java.awt.*;
    
    /**
    * render a the AppSate enum cell, use icon without text.
    */
    final class AppStateRenderer implements TableCellRenderer
    {
    // ------------------------------ FIELDS
    ------------------------------
    
    private static final JLabel template = new JLabel( "",
    JLabel.CENTER );
    
    private Color background;
    
    private Color selectedBackground;
    
    // -------------------------- PUBLIC INSTANCE METHODS
    --------------------------
    /**
    * constructor
    *
    * @param background background colour
    * @param selectedBackground background colour when seleced
    */
    public AppStateRenderer( Color background, Color
    selectedBackground )
    {
    this.background = background;
    this.selectedBackground = selectedBackground;
    }
    
    public Component getTableCellRendererComponent( JTable table,
    Object value,
    boolean
    isSelected,
    boolean hasFocus,
    int row,
    int column )
    {
    System.err.println( "selected:" + isSelected + " " + row + " "
    + table.getSelectedRow() );
    
    template.setIcon( ( (AppState) value ).getIcon() );
    template.setBackground( isSelected? selectedBackground :
    background );
    
    return template;
    }
    }

    (*) Ready to use examples - the best way of getting started with RMI in
    Eclipse
    
    The RMI Registry inspector has greatly improved and it can now invoke
    almost any remote method (in previous version it was only possible to
    invoke methods that receive no arguments).
    
    Also new in v2.0 - enhanced Java 5 and Java 6 support.
    
    The standard set of features includes
    (*) Automatic stubs genaration
    (*) Local RMI registry control (start/stop/clean)

  - To really foul things up requires a computerPartner just got back from a new government job with an amusing tale.
    
    BC is a large province (about 1000 miles top to bottom) so the BC
    government decided to set up a computer system so that any printout
    could be directed to any printer in the province, thus saving on
    courier costs.
    
    However, the default is the system selects a non-busy printer, not
    worrying particularly if it is 1000 miles from the intended recipient.
    
    The printouts don't have proper headers to direct them to the person
    eagerly awaiting them so most of the printouts ended up in the
    shredder.

  - Roedy 's convertor, Where is Short ? Where is Byte?Hi Roedy,
    
    This is what you advertise for in
    http://www.mindprod.com/zips/java/converter.txt:
    
    signed byte Byte
    unsigned byte Byte
    short Short
    char Character
    int Integer
    long Long
    float Float
    double Double
    char[] String
    
    This is what you have in your code:
    
    public static final String [] flavours = {
    "boolean",
    "/*signed*/ byte",
    "/*unsigned*/ byte",
    "short",
    "char",
    "int",
    "long",
    "float",
    "double",
    "String",
    "Boolean",
    "Character",
    "Integer",
    "Long",
    "Float",
    "Double"};
    
    Noticed anything? Is it voluntary or did you forget java.lang.Byte
    and java.lang.Short?
    
    Either the advertisement or the code need to be updated.
    
    My apologies if you have already explained why.
    
    BTW, neat little tool I always come back from time to time.
    
    Cheers, Mike

  - How do i implement this interfacepublic interface AQuestion
    {
    public abstract void someMethod() throws Exception;
    }
    
    http://www.angelfire.com/or/abhilash/Main.html
    
    see Question no 5.
    
    How do i implement this interface ?
    
    (1) problem is, it has an abstract method and hecne its complicated
    to implement this class.
    
    (2) another problem is, it is the public interface and hence we can not
    make one more public class in the same file....because 1 file can have
    only 1 public access specifier.
    
    is it really possible to implement this interface ?
