  - jEdit JavaDebuggerDoes anyone know how to set this plug-in up? I have loaded it in jEdit
    but everytime I try and use it it gives a huge long error list and says
    I need JDK 1.3 or above, even though I am using JDK 1.5!

  - 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

  - 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.

  - [ANN] RMI Plug-in for Eclipse v2.0A new version of the RMI Plug-in for Eclipse (v2.0) has been just released.
    
    In the new version there are two new major features:
    
    (*) RMI Spy - Live monitor of the RMI activity in an RMI application
    (*) 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)
    (*) RMI Application Launcher - easy codebase and security policy
    configuration.

  - 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?

  - 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?

  - 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;
    }
    }

  - 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,

  - 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 ?

    -= 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.

java-programmer, Eclipse and Tomcat Development Hi,

I am trying to figure out how to change the build path for my java servlets
in eclipse so that my class files are located within my Apache Tomcat
servers class directory. I tried to change the output folder in eclipse for
the project properties but it doesn't seem to accept it as a valid
directory. It only accepts folders with the current projects working
directory (ex. eclipse\workspace\myProject). Any idea how to do this without
the use of plugin's. If not can someone recommend me the most popular plugin
to get this job done. Thanx in advance

Joe

    does anyone know if there is a plugin that will create uml diagrams from my

    to use poseidon, but i have not really been able to integrate it into my
    netbeans ide.

  - Applet Security QuestionI will soon be writing my first applet. While I've done quite a bit of
    programming local classes in Java, I have barely done anything but read a
    few bits of information on an applet.
    
    This applet will be for my clients to edit their settings, which means when
    started the applet needs to know the client's name and password. The page
    the applet is started from is on a secure server and only able to be
    accessed as a secure page and is reached from the client logging in from
    another page.
    
    The only way I know of that I can pass the password on to the applet is by
    including it in the web page itself, as a parameter to be passed to the
    applet. As I said, the page is secure and can only be reached by logging
    in with the password in the first place.
    
    How much of a security risk is it to have the password included as a
    parameter for the applet if it is on a secure page as I described? I have
    considered encrypting it, but it would have to be light encryption. I know
    even light encryption is better than nothing, but how secure is it just to
    make sure the page itself can only be accessed with a password and is a
    secure page?
    
    Thanks for any help and/or clarification.

  - Any goodhearted person willing to explain me a program in Java I gotHello
    
    What I'll will ask may take some of your time.
    
    I have no experience at all with Java. But I could get my hand on a
    programme written in Java, which does exactly what I want.
    
    But I'm eager to learn, and want to know how it does everything.
    
    I'm not interested in the visual aspect but in the communication
    
    What the program does is communicate with a little box, that catches
    data from a machine.
    In essence it replaces a printer.
    The machines prints to a usb port, via a adaptor, the printing data
    goes into a little box, and then via a usb connection goes to the
    reading pc.
    
    I want to understand that.
    
    Does anyone has some spare time for this (and "teaching skills") ?
    
    I have the jar's and the classes (decompiled also)
    
    For the moment I will not post the sources online.
    
    Many thanks in advance and have a nice day

  - Slavemode in CLDC HotSpot ImplementationHello All,
    
    I have a small query regarding CLDC Hopspot Implementation... I hope
    some of you would kindly find some time to answer the same :)
    
    I have to do an OS-porting of Hopspot Implementation and I have just
    started to analyze the code... As I understand, in slavemode, the
    control would be given back to the calling function after the JVM has
    executed few bytecodes. Now:
    
    1. Is there any way to control the number of bytecodes/instructions the
    JVM executes before returning.
    2. If the return value of JVM_TimeSlice() is not -1 or -2, is it
    advisable to change the return value of the function? If yes, what is
    the best way to achieve this? [This is to have a better control on JVM]
    
    I hope I have made my point clear enough, anticipating an early
    response,
    
    Best Regards,

  - Java rendering problems when antialiasing is enabledI've written a Java app which uses Swing to display images and text.
    
    The app consists of a JFrame which contains a JPanel-derived class. In
    the paint() method of the JPanel-derived class, I call
    Graphics.drawImage() to render an image file previously loaded with
    ImageIO.read().
    
    This was working fine until I enabled antialiasing in my video card
    settings (GeForce FX 5200 w/128MB RAM, Windows XP SP2). With
    antialiasing, none of the content gets rendered in the window. The
    problem exhibits itself when I'm tring to render the image myself and
    when I just have a JProgressBar control displayed in the window (i.e.
    the Swing components themselves aren't correctly rendering with
    antialiasing turned on either).
    
    I've received feedback from multiple users seeing this issue as well,
    so its not just my machine.
    
    Any ideas? Disabling antialiasing fixes the problem, but I'd like to
    be able to get my app to work regardless of whether antialiasing is
    enabled/disabled.

  - Is JAR signing _ever_ harmful?I'm having a series of ructions with our on-site installation people,
    re: JAR signing. It's a big app, big budget, and we have lots of
    be-suited consultants running around on customer sites for long
    periods. I live back in the coder's garret, making the product.
    Sometimes they throw me the odd doughnut.
    
    Basically they're reporting every bug and misconfiguration they can
    find as being caused by our recent switch to JARs rather than loose
    .class files, and in particular by these JARs being signed. It's a
    self-generated key, without an X509 cert (at present).
    
    Before I go postal with the +3 Lart-o-doom, can I please ask if there
    are _ANY_ circumstances, no matter how perverse, where signing a JAR
    could cause something to break? I know of nothing. Nada. Zilch.
    
    One problem we have had was due to signing across two JARs having been
    done by different keys. As the real problem here was trying to mix code
    from product versions V1 and V2 (a big non-no anyway) then I see this
    more as a feature than a bug. But try telling them that...

  - JMF usage question
    
    I've ended up with a situation which positively requires Java, which I
    have very little experience with, and am basically trying to have one
    or more other controls in a browser applet which uses the java media
    player and JMF. I've tried to simply add a TextArea widget next to
    the media player in one of the standard examples they provide, but all
    that comes up is the media player. I'd appreciate it if anybody could
    tell me what I'm doing wrong here:

  - How to set size for JComboBoxHi all,
    
    I am developing an application, which will have two JComboBoxes and
    two JTables, and i am using gridbag layout.
    
    when the initial string for JComboBox is small enough then these
    sets(JComboBox and JTable) are divided equally, when the initially
    string is big then the two sets(JComboBox and JTable) are not divided
    equally, how can i divide them equally irrespective of the string
    length.
    
    I used the setSize(),setPreferredSize(),and setMaximumSize() for
    JComboBox but there is no result ,
    Plz help me,
    
    Thanks in advance

  - RegEx !compileHi,
    
    I am using Eclipse, Java SDK 1.4 and the java.uitl.regex
    
    I am trying to using regular expressions in my code
    
    I could write something simple like:
    
    String re = "\d";
    
    And I am receiving an invalid escape sequence error.
    
    And I am not so sure why

  - Row "headers" in JTableJ2SE 5.0_05 on Windows Server 2003 SP1.
    
    What I want to do is something like a column header only it's a row header
    that is effectively a JTable column that is fixed in position on the left of
    the view and can't be reordered or gain focus.
    
    Is this possible? I've looked through the documentation and done a Google
    search but can't find anything which probably tells me that it can't be
    done. What are your thoughts? It probably needs scroll behaviour similar
    to a header too.
    
    Thanks,

    Out of curiosity, I tried to test if the above is true. It didn't make
    any difference. In fact, C++ was a bit faster (not by much, just 6%).
    Probably due to array bound check in Java, if there is in indeed an
    issue with C++ arrays, overall there is no difference.
