  - Struts, Spring, ... what about Swing?So many Web frameworkings seem to have sprung up but are there any
    really good frameworks for fat clients using things like Swing?
    
    I am most interested in how the server side objects interact with Swing
    components, the design patterns behing client/middleware/server/db apps
    etc.
    
    thanks

  - Change listbox mouse selection to not use ctrl keyI'm converting a program from Windows where the LBS_MULTISEL option allows
    selecting rows in a table with a single mouse click. On the other hand,
    with Swing you need to hold down the ctrl key and then it's buggy,
    seemingly requiring rows to be clicked from top to bottom.
    
    If there's an example of changing the Swing behavior, I haven't found it.
    I've made some progress figuring it out but can't spare much more time.
    
    Anyone know of a working solution? I can't be the only one needing it.
    
    I can post what I've tried so far if a ready-made solution isn't available.

  - renameTo for Directories on SolarisI've been attempting to rename a directory on Solaris 8 and continue to
    have problems.
    
    I read other threads that mention it is not possible to do when moving
    between partitions on Solaris, but I am renaming to the same
    paritition.
    
    I am basically attempting the following:
    
    File oldName = new File("/opt/OldDirectoryName");
    File newName = new File("/opt/NewDirectoryName");
    
    if ( oldName.renameTo( newName ) )
    // Successfully renamed
    else
    // Failed to rename
    
    For some reason I seem to continually be unable to do this.
    
    Any ideas?

  - converting between double and integerI have a variable declared as a double as :-
    
    sValue = Math.floor(Math.sqrt(polynomialDegree));
    
    where 'polynomialDegree' is an integer.
    
    How do I convert 'sValue' to an integer?? I cant declare sValue as an
    integer straight off because its returning an error message saying 'possible
    loss of precision', and have tried to convert it to an integer using
    intValue() but keep getting an error saying 'double cannot be dereferenced'
    
    Where am i going wrong?
    
    Thanks

  - client server communication in java I have a java web service that returns byte arrays to the client.
    First a byte array is returned and the server gets the acknowledgement,
    then the next byte array is sent and so on. But I don't have much idea
    how to implement it. How can I resume from where I stopped at the
    server side? Can anyone give me some idea so that I can proceed?

  - [Sizing: Tomcat 4.1.x] Memory Usage for the Session TrackingHello all,
    
    i'd like to know how much memory the application server
    have been used for tracking a new session.
    
    i've tried the jProfiler from the ej-Tech however i found
    seems it don't have an easy way to calculate the total
    amount of memory the related object instacnes used for the
    session tracking. i guess org.apache.catalin.session* is
    the point to start with, however, to me, it's a little too
    hard.
    
    do anyone of you have did this similar thing?
    
    say, to calculate the total amount of memory used, when a
    browser visit a particular page, and the server create new
    sesssion related objects and return the browser a new cookie
    with 2 attributes initialized? e.g., name="matthew", sex="M"?
    
    thanks a lot in advance.

  - Socket functionality on jre 1.6.0 beta b59g
    OK, it seems that on Windows XP Pro, that Socket has changed significantly,
    breaking lots of my code.
    
    Using "localhost" no longer appears to work to create a Socket object
    on a port. Have to use "127.0.0.1" instead. Other aspects of Socket
    also appear to be flaky/changed... I can certainly "ping localhost" so
    it's not that localhost has a problem.
    
    Can someone please explain the plain Socket changes for this new 1.6 ??

    In the jsp there is a validation where we check for the length of the
    body using the following:
    if (formname.body.value.length == 0)
    {
    isFormComplete = false;
    }
    
    Need to know which are the possible cases when the length of the form
    could be '0'.
    The behaviour is real weird. Roughly 2 out of 10 times the length comes
    as 0 even when the user enters all the details. What could be the
    reason for the same ?
    Any pointers are highly appreciated.

java-programmer, HELP needed: Small Java applet I need a graphic Java applet that makes the following steps:

Given a circumference of radius "r",

Draw onscreen, say, 20 random radius.

Then, every time you press a button:

Rotate the 20 radius a given random angle (same for everyone).

Draw the new radius onscreen.

Note: The radius endpoints should be stored in float arrays and drawn as
float. (Of course one of the endpoints of every radius would be the center
of the circumference.)

I'm not very good at Java at the moment but I'd like to transform an old
program from QBasic into a java applet and I think that this little
framework is all I need. What I am getting at the moment is a lot of
compilation errors I don't understand.

The program I want to transform is here:

  - Newbie:Please suggest ebook or any reading material for creating rich clients interfaces in javaWhile googling I found a very interesting presentation on creating
    amazing GUI's in java on this link -
    http://developers.sun.com/learning/javaoneonline/j1sessn.jsp?sessn=TS-3548&yr=2007&track=2
    . I was very much impressed and really want to read and learn more on
    developing such interfaces. So please suggest some reading material
    for this.
    I know core java and basics of swing.

  - Which IDE to choose (more specific than earlier, very similar post)?Hello guys,
    
    I'm C++/Windows programmer and I'd like to smoothly switch to Java. I read
    replies to earlier, very similar post, but I didn't even hear about such
    IDEs :-(
    My question is following: using what IDE can I easily create applets with
    controls like edit, list, combo boxes, buttons, tree controls and - this is
    very important - have support to draw 3D graphics? Some time ago I was using
    Borland JBuilder, but I guess it was not intended for building commercial
    releases. I was browsing Sun Microsystems' site and found free "Sun Java
    Studio Creator, Early Access". Can I create in it commercial applets using
    features that I described above? If not, please advise me something free or
    really good enough (read: easy to develop applets) to spend money IDE;
    preferably free of course :-)
    Generally I focused on "Sun Java Studio Creator, Early Access", but I'm
    waiting for your replies.
    Please reply, your opinion is crucial for me.
    
    Regards
    
    P.S. I'm not going to create server-side applets. I will be doing applets
    run in web browser.

  - EnterpriseBean and finalize()Hi Everyone,
    I'm trying to learn EJB and picked up a copy of the book "SCBCD Exam
    Study Kit" by Paul Sanghera. Inside it, I came across the following
    sentence, which piqued my interest because I cannot see a) where this
    can be found in the EJB 2.0 specification (actually, I was looking in
    the J2EE 1.3 specification), or b) why finalizing a bean would be
    interfering with the responsibilities of the container. Here's the
    quote:
    
    "... the bean class must not have any finalize() method because by
    doing this you would be stepping on the container's toes, since it is
    the responsibility of the container to manage the lifecycle, threads,
    garbage collection, and so forth."
    
    If anyone can shed a little light on this, and dispel the confusion,
    I'd really appreciate it.
    
    Many thanks,

  - How to detect existing text tables in a hsql db?I have a Java-Application that creates several text-tables at the first
    start. When I start the application again I just want to check, if the
    text tables exist. But the application always returns a "false, table
    does not exist" and the localdb.properties and localdb.script files are
    written new. After that, the tables can be detected, but only until the
    next start of the application.
    
    dbcon.connect(LOCALDRIVER, LOCALPROTOCOL, LOCALDATABASE, LOCALUSER,
    LOCALPASS);
    
    DatabaseMetaData metadata = dbcon.con.getMetaData();
    String[] aTyps = new String[]{"TABLE"};
    
    ResultSet result = metadata.getTables(null, null, "%", aTyps);
    while (result.next()) {
    System.out.println(result.getString("TABLE_NAME"));
    }
    result.close();

  - Use of JVM id and Event Notifier patternIn our design for event subscription/publication, a JVM id is used to
    identify the event channels (or event brokers). The JVM id refers to
    an EventChannel on a host and there will be one EventChannel per host.
    
    FYI, More information about Event Notifier pattern is available at:
    
    http://members.ispwest.com/jeffhartkopf/notifier/
    
    Is it okay to refer to JVM id (kernel level details) to identify a
    user level class like EventChannel ? I feel that EventChannel should
    be referred by some other way.
    
    Any pointers will be appreciated.

    If you have downloaded the J2SE 1.5.0 SDK (or the JDK 1.5.0) and ran
    the installation, you do not need to install JVM (i assume you mean
    JRE). The java console will look different if you have installed the
    JDK.
    I am not sure if you can keep two jdks installed. It is possible, but
    if you want to save yourself frustation, uninstall the previous jdk
    (and jre. Installing the jdk installs jre too along with it. :) ) and
    install the new one.
    Dont know about netbeans. Possibly, it needs the JAVA_HOME variable
    set.
    Also the documentation is totally separate. You just need to unzip to a
    folder to read it, and not install. Its just a bunch of html files. Do
    not worry about it. You can have as many docs of different versions as
    you want.
    
    Probably you messed up the internet settings so the problem with
    thunderbird. nothing to do with java i suppose. not sure since i have
    not used thunderbird yet.

  - Synth L&F as jarHello,
    
    i am trying to build a L&F basedf on Synth but now i have problems
    using the L&F in another project. I pack the L&F into jar add it to a
    projects classpath but it is not possible to access the images
    contained in the jar. I know that resources from a jar should be
    accessed by:
    
    MyResourceBase.class.getResource("path/relative/to/the/MyResourceBase.png")
    
    the problem is that its not me who accesses the images but synth. AND
    when i look into synths code the images should be loaded by:
    
    new ImageIcon(url, null).getImage()
    with url is the return of:
    private URL getResource(String path) {
    return _resourceBase.getResource(path);
    }
    
    That looks correct to me but it does not work. Has anyone build his
    synth L&F and got it to work from a jar? If that does not work, what is
    a custom L&F good for if it can not be deployed as a jar?
    
    I am very thankfull for all hints

  - using importI'm trying to import the Welomb class in the java divelog tutorial into
    another application. But when I type import divelog.* it refuses
    
    the absolute path for Welcome is
    d:\Documents\Java\Divelog\src\divelog
    
    the application I'm trying to import it from is at
    
    d:\Documents\Java\Frames\src\frames
    
    I've also tried creating a library (MyLibrary) and pointing to the
    divelog.jar file and setting the classpath to point at divelog.jar. I've
    then added the library to my project but when I try and create a Welcome
    class it says it cant find the class. So neither using a library or
    importing work.
    
    I'm using sun java studio enterprise8 (free) does anyone know how to import
    the divelog package into my app using an import statement.
    
    I've tried the following with no success
    
    import divelog.*
    import Documents.Java.Divelog.src.divelog.*
    in both cases I get package diesnt exist
    
    any suggestion welcome!!

  - Creating tiled image from multiple tiff sources in JAIHi all,
    
    My situation is as follows. I have a number of tiff files containing
    adjacent tiles which I would like to combine into one image. Currently I
    achieve this goal in the following manner using the Java Advanced Imaging
    library:
    
    1) Create a target TiledImage with attributes appropriate to hold all tiles.
    2) Load each tiff file into a separate PlanarImage.
    3) Get the Rasters of each of these PlanarImages and translate coordinates
    according to the rectangle they must occupy in the target TiledImage
    4) Invoke TiledImage.setData(Raster) with the translated raster for each
    tile
    
    This works ok, but it does not seem to take advantage of the JAI's
    pull-model; image data is loaded into memory immediately, probably as a
    consequence of the call to getRaster(). However I wish to defer the loading
    of image data into memory until it is needed, because only a subset of all
    tiles are two be displayed at any one time.
    
    I hence believe I need something along the lines of the NullOpImage class.
    Unfortunately, the constructor for this class only takes a single source,
    while I need to be able to pass a source for each tiff tile. One solution is
    to subclass NullOpImage (or its superclass, PointOpImage) and take care of
    things myself. Is this the way to go about it, or is there a better and
    easier solution?
    
    Any suggestions will be greatly appreciated.
    Regards,
    Michael.

  - Playing (MIDI) sounds from Java applet (Shepard's Tones)
    
    The applet for endlessly rising/falling scale
    (auditory illusion)
    on this page is fantastic!
    
    http://www.cs.ubc.ca/nest/imager/contributions/flinn/Illusions/ST/st.html
    
    How is this done?
    (I'm assuming it uses MIDI.)
    
    Is this sound applet playable from any
    java-enabled browser on any Windows system?
    
    How about on Mac or Unix?
    
    I'm asking because I want to write
    Java programs that plays simple
    2-part inventions by Bach.
    
    Thanks.

  - Newbie Question - ArrayLists and methodsHello all (again),
    
    My problem here is that I'm trying to build a list of ArrayLists that
    hold data and I want to add the newly derived data into a table where
    it's dependent on the first row. A short version of my program to
    illustrate what I mean:
    
    import java.util.*;
    public class MyProg2 {
    public static void main(String[] args) {
    List table = new ArrayList ();
    List <Integer> data = new ArrayList <Integer>();
    data.add(1);
    data.add(3);
    data.add(4);
    table.add(data);
    
    System.out.println ("table(0) = " + table.get(0));
    
    ArrayList <Integer> newNode = new ArrayList <Integer>();
    newNode = createNode((ArrayList)table.get(0),0);
    table.add(newNode);
    System.out.println ("Added in a new row and table is now:");
    System.out.println ("table(0) = " + table.get(0));
    System.out.println ("table(1) = " + table.get(1));
    
    } //end main driver
    public static ArrayList createNode(ArrayList items,int lParen){
    int a = 0; int b=0; int c=0;
    if (items.size() >= 2){
    a = Integer.valueOf(items.get(lParen).toString());
    b = Integer.valueOf(items.get(rParen).toString());
    c = a + b;
    items.remove(lParen);
    items.remove(lParen);
    items.add(lParen,c);
    }
    return items;
    }
    }
    
    (I'm unable to get rid of all the unchecked msgs because putting the
    <Integer> tag sometimes made the program uncompilable. Use --nowarn
    when you compile this program. :)
    
    Iin this code, row 0 of table is changed in the method while it
    creates row 1, but I don't understand why and don't know how to keep
    it from changing. From this behavior, it's leading me to believe
    ArrayLists are passed by value or is this the way of ArrayLists? I
    thought parameters were passed by reference? What am I missing here?
