  - JTables and dynamically adding dataHey,
    I have a JTable that I want to add a new column to every time someone
    clicks a button. I have been reading about extending the
    AbstractTableModel, but I don't how this allows you to add a new
    column. The examples online show what happens when a user edits a
    table, but I don't want that. I want it add when the user presses a
    button outside of the table. Some advice would be appreciated.
    
    Thanks

  - Problem with TableDear all,
    
    I have a TextField and a TextFieldHandler implement ActionListener and
    a Table.
    
    How can I do the following function?
    
    When the user type 111 in the TextField and press enter, item 111
    information is retrieved from database and will be displayed in the
    table.
    When the user type 222 in the TextField and press enter, item 222
    information is retrieved from database and will be displayed in the
    table.
    
    ( I know how to detect the value entered in the TextField, but I donno
    how to display the corresponding information with a Table)
    
    Thanks for reply.

  - NIO! Nein!I recently had the misfortune of trying out a InputStream.available()
    command, only to find out it doesn't work on sockets.
    
    I've found that the solution to my problem is the Nio SocketChannel
    class, and now I have only one question:
    
    What was Sun smoking when they came up with SocketChannel and where can
    I get some?
    
    SocketChannel* and the SSLEngine is probably the most complicated way of
    doing socket work and I can only wonder whose crazy idea it was.
    
    Why couldn't they just make .available() work as advertised?
    
    *sigh*
    
    Just wanted to publically complain about unncessary complication.

  - in need of swing performance adviceHi All,
    
    I've hit a point in my app when I first call .validate() when loading a
    new panel (it is fairly complex), it takes up to 5 seconds to load..
    There must be something I can do to get over this and was wondering if
    anyone had any ideas, if you are interested then my App flows like this..
    
    A quite simple frame is initially created and displayed to user, this
    contains a button with 4 buttons, a BIG panel and a menu bar and thats
    it for now. the button bar is on left, menu at top and the Panel taking
    everything else up..
    
    When the user clicks a button, an appropriate panel is then called and
    'loaded into' the big empty space where the panel is. All this is in a
    function called Show() which is as follows...
    
    private void show(Component component) {
    java.awt.GridBagConstraints gridBagConstraints;
    gridBagConstraints = new java.awt.GridBagConstraints();
    gridBagConstraints.fill = java.awt.GridBagConstraints.BOTH;
    gridBagConstraints.anchor = java.awt.GridBagConstraints.NORTHWEST;
    gridBagConstraints.weightx = 1.0;
    gridBagConstraints.weighty = 1.0;
    
    Main.removeAll();
    Main.add(component,gridBagConstraints);
    this.validate();
    }
    
    when a button is clicked, depending on the button I call the show
    command like this...
    
    show(new divelog.forms.ProfilePanel());
    
    The panel that gets loaded that I have a problem with containt 3 panels
    in a tabpanel. each one of those has a table, and maybe 10 textfields
    per panel.
    
    So not really all that much complexity I dont think, the instantiation
    of the panel doesnt take long, so setting up the listeners I have seems
    ok its just the moment the .validate() line is executed there is the 5/6
    second delay.
    
    Anyone any ideas ? I was thinking Ok I'll create the instances of the
    panels in a seperate thread, but as I said the creation doesnt really
    take anytime at all.
    
    Thanks in advance.

  - collaborative QA testingDoes free or cheap code to do this already exist? What is this
    generic sort of product called?
    
    I want to set up a collaborative QA checklist, so that many people can
    be testing at once and reporting what they have tested. Everyone sees
    the incoming results like on election night, so they can see what
    still needs to be done. It also allows for crucial stuff to be tested
    by more than one person, and to record their conflicting results.
    
    It might have columns for different platforms, and some sort of HTML
    script to describe the sections and tests.
    
    The problem is getting emergency coverage testing done at the last
    possible minute to deal with any "insignificant" last minute changes.

  - Possible to split a PrinterJob ??Hi all,
    I am using java Printerjob with Book to create some page to print.
    The problem I have is that the generation of all the page a pretty
    long.
    I usually gets 100 pages and each page take up to 2 seconds.
    
    I would like to know if there is a way to start the printing process
    as soon as page are ready and not wait 5 minutes to create the batch
    and after that another 3-5 minutes with the printer ?
    
    Can we append page to the book once the print is started ?
    thanks,

  - [Swing] JScrollPane double MouseMotionListenerhi,
    I am targetting JRE 1.5.
    I have an image displayed within a jscrollPane (with scrollbars).
    (in this way : new JScrollPane(new JLabel(new ImageIcon(image))))
    
    I have a MouseMotionListener added to the JScrollPane, so when the
    mouse goes over the visible part of the image, I can get the relative
    coordinates of the mouse
    
    My question is how to I get at the same time, the coordinate of the
    mouse relative to the jscrollpane (the coordinates within the visible
    part of the image) and the absolute coordinates (the coordinates of
    the mouse relative to the whole image itself).
    
    I tried adding also MouseMotionListener to the JLabel and that gives
    me the the coordinates of the mouse relative to the whole image
    itself, but then the event is lost for the jscrollpane's listener.
    
    How can I achieve that simply ?

  - jvm class path unicode native methodsOkay.. I'm having the following problem.. I've tried pretty much every
    solution I can think of but always hit some brick wall.
    
    I need to:
    load classes from a jar in a unicode directory and register native
    methods for those classes.
    
    Before (the unicode) I was simply doing a -Djava.class.path=myjar.jar
    And then registering the native methods..
    
    But.. I can't find a way to send a unicode code string to through the
    -Djava.class.path..
    
    So I've tried:
    
    1. sending the string as utf8.. nope.
    2. setting environment variable classpath with
    SetEnvironmentVariableW.. nope.
    3. creating my own url class loader with the jar..
    Loads fine.. BUT NATIVE METHODS DO NOT REGISTER CORRECTLY (even
    though the jnienv says they do.. they don't.. apparently I can only
    register native methods from classes loaded from the jnienv_ sucky..)
    
    4. creating my own url class loader that loads the byte code directly
    from the jar, then calls defineClass from the root class loader.
    NOPE.. because classes reference each other.. therefore the entire
    jar must be available when ever I reference one class.
    
    5. found out the class Launcher and its methods getClassLoader,
    appendblahblahfor instrumentation..
    NOPE.. although.. I've sort of giving up now.. this is going too far.
    
    Any help?
    Surely there are some japanese programmers that have dealt with this
    before.

  - Java Native Interface: "Translate" java call to JNI, how to pass parameters, how to show exceptionHallo,
    
    I am at least one step further, now I need to pass the properties to
    the call and are now sure how:
    
    Remember: The call I want to implement in Delphi is
    java -Xmx256m -cp
    "lib\fop\fop.jar;lib\fop\avalon-framework-4.1.3.jar;lib\fop\JimiProClasses.zip"
    org.apache.fop.apps.Fop -fo "Data.xml" -c "lib\fop\Config.xml" -pdf
    "Data.pdf"
    
    So the parameters that have to be passed are:
    -fo "Data.xml"
    -c "lib\fop\Config.xml"
    -pdf "Data.pdf"
    
    If I do
    JNIEnv.CallStaticVoidMethod(Cls, Mid, ['-fo "Data.xml" -c
    "Config.xml"-pdf "Cover.pdf"']);
    (all parameters in one string) or
    JNIEnv.CallStaticVoidMethod(Cls, Mid, ['-fo "Data.xml"', '-c
    "Config.xml"', '-pdf "Cover.pdf"']);
    (each parameter in a separate string)
    
    ...then JNIEnv.ExceptionOccurred is not NULL after the call, thus some
    exception occured.
    
    The parameter Args in the call CallStaticVoidMethod() is an array of
    const. In CallStaticVoidMethod() the array elements are converted to
    JValues with ArgsToJValues().
    The exemplary C++ code in the doc PDF works with an ObjectArray created
    with NewObjectArray(). I tried that, but CallStaticVoidMethod() won't
    accept an ObjectArray, nor would the similar procedures
    CallStaticVoidMethodA() or CallStaticVoidMethodV().
    
    By the way: My Delphi app runs in a window, its not a console
    application. Can I get the description of the exception with any other
    function, or how would I have to use ExceptionDescribe() in this
    context?

    Well, no, it just takes perseverance. Being careful not to junk the

    Indeed; in 30 hours so far, I've removed roughly 3500 emails either
    containing the virus or saying they were forwarded with the virus
    removed. This to my Unix ISP account, where mailx() is my friend and
    companion for weeding through the end results of Microsoft's sloppy
    coding practices.
    
    Too bad California's refusal to allow the M$ denial of "fitness for
    merchantability" cannot be reflected world-wide; a class action lawsuit
    for damages would redistribute all of M$'s wealth and capital equipment
    to the Internet as a whole.
    
    Meanwhile, 200,000,000+ flawed email clients are trying to find my email
    box with their virus copies.
    
    Sigh; it is going to be a long next few days.

java-programmer, EJB Remote Calls - Serialization Restriction(s) Hi,

I have a simple HelloWorldApplication which uses SSbs.

I pass a Customer Object which has two attribute String name and
Address address;

I made Address not-serializable

so when i make calls to the SessionBean i get a remote Exception which
contains the not-serializable exception in WebPShere (as expected)

To my surprise this application ran without any problem in JRun4.0

Why would that be the case and what would the result in other APp
Servers like WebLogic be?

AFAIK, objects (parameters and Return types) must be serializable for
all Remote EJB Calls.

Note this applicaiton does not use Local Interfaces..

TIA
Manglu

What kind of client are you using to call the EJB? A webcontainer
(servlet/jsp), an application-client, or a standalone client?

If you're calling the EJB from the webcontainer my guess is that JRun
runs the webcontainer in the same JVM as the EJBContainer, and optimizes
the remote invocation so that it goes 'in process' (i.e without
serializing/deserializing the parameters).

    Sure, because it is the output of the comparision functionality.
    
    Trouble is it is too broad, you only need three values, not two ranges
    and a central value.
    
    I put a wrapper interface (named "Sortable") around the comparision
    functionality so that it would emit specifically -1, 0, or +1, as
    manifest constants named LESS_THAN, EQUAL_TO, and GREATER_THAN, on which
    I can then use a simple, symmetric, and clean switch syntax.
    
    Given enumerations, that would presumably be even easier, because then
    you could exhaust the enumeration type to the satisfaction of the
    compiler, and wouldn't have to include a "default" switch case, the only
    wart in my current setup.

    Opening the port seems good, i send data to the machine but when i read
    th response i have a buffer with bytes null.
    I have tried to sniff the serial port but i don't understand the data i

  - Comparables and GenericsHow do I express "A Comparable that can be compared to itself" in generics?
    
    I have a method that takes as parameter an array of Comparables.
    Whilst trying to "modernize" this code, I can no longer write simply:
    
    public void myMethod(Comparable[] primaryKeyValues)
    
    but need to add "generic info" to Comparable.
    The only requirement I have is that the objects should be able to run a
    compareTo() on an instance of their own classes.

  - Eclipse Appearance ProblemHi all,
    
    I have Eclipse (version: 3.2.2) and JRE (version:1.6.0.1) installed on
    my Windows Vista System. When I am working regularly with Eclipse I
    encounter with disappearance of some regions of Eclipse window.
    Specifically package explorer and console regions are becoming a white
    area right after I switch(focus/bring to front) from another
    application to Eclipse. If I resize the Eclipse window or just make
    some mouse gestures over those white area, they return back to normal.
    
    I have no idea about the problem so I could not goggled it. Here is a
    screenshot: http://www.imagehosting.com/show.php/502707_20070421132840.png.html

  - J2ME: allowing for "Allow HTTP traffic?" confirmation when doing a connection timeout mechanismI'm using threading in a J2ME app to allow a timeout on an attempt to
    connect to server. However, I'm having an issue with the usual
    confirmation the user gets on first connection attempt: you know, the
    message that say something like "This application would like to send
    HTTP traffic. Allow this?" The problem is that I have no idea of how
    long the user takes to read this message before hitting "ok", so my
    connection timeout could timeout before the user has even hit ok and
    before any connection attempt has been made!
    
    Is there any callback available so that I know when the user has
    actually hit 'ok'?
    
    My current workaround is to make a dummy first connection to a bad
    address, e.g. "http://x", just to get the user to hit 'ok' and get that
    out of the way before making my proper connection attempt.
    Is there a better way though? This technique makes an attempted DNS
    lookup which wastes a little time.
    
    Thanks.
    
    N.B.
    I'm aware that in some cases the user can have a preference set so that
    the HTTP traffic alert happens before *every* server communication, but
    I'm ignoring this case for the moment.

    Correction, that number could be wrong, it is registered to "Dufresne."

  - have tomcat run a c binary via cgiAnyone know how to make tomcat run an actual exe?
    
    I'm using windows 2000.
    
    I can get it to print the binary contents of the exe to the web page,
    but not actually execute it.
    
    The docs indicate that you specify an executable in web.xml where you
    specify cgi and that the default is perl, but I don't need an
    interpreter to run an exe.
    
    thanks

    3) Copy (clone()) the Hashtable. Iterate over the copy. If you find an
    entry in the copy that should be removed, remove it from the original.
    Make sure that no other thread works the original Hashtable while you
    enumerate over the copy and manipulate the original.

    That should not be a problem as long as each one of them is listening on a different port and you have enough memory. We have an application that uses embedded Tomcat and I can start about 15 instances without any problem. I have about 1GB of memory and the initiali heap for Tomcat is set the the default, which I bellieve is 2 MB.

    Hi,
    
    Just curious to see if anyone has run lots of separate tomcat instances on

    I'd like to be able to host a number of separate instances of my app on the

    They will not be heavily used, so I guess RAM is the biggest factor.
    Unfortunately I am on windows 2000 not *nix, so paging will be an issue.
