  - 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?

  - 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?

  - 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

  - 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.

  - Regex syntaxI have managed to form the regex for the following two:
    
    CTL = <any US-ASCII control character (octets 0 - 31) and DEL (127)>
    
    String CTL_REGEX = "([[\\x00-\\x1F]\\x7F])";
    
    LWS = [CRLF] 1*( SP | HT )
    
    String LWS_REGEX = "((\r\n)??( |\\x09)+?)";
    
    However, the following stumped me for hours.
    
    TEXT = <any OCTET except CTLs, but including LWS>
    
    String TEXT_REGEX = ...... // help me out please.

  - 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:

  - 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();

  - 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?

  - 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.

  - 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

When you compound textspeak on top of ESL, you get a doubly difficult

"With console?"

Do you mean how do I get a console in Java? That comes with it.

Do you mean how do I download if I don't have a GUI? Try Lynx or Links
or maybe wget or appget.

    by showing it growing. i.e. something like the following:
    
    while(scale <= 1) {
    repaint();
    scale += 0.05;
    try {
    Thread.sleep(25);
    }
    catch(InterruptedException e) {
    e.printStackTrace();
    }
    }
    
    public void paintComponent(Graphics g) {
    super.paintComponent(g);
    Graphics2D g2 = (Graphics2D) g;
    g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
    RenderingHints.VALUE_ANTIALIAS_ON);
    g2.setComposite(AlphaComposite.SrcAtop);
    g2.transform(AffineTransform.getScaleInstance(scale, scale));
    g2.fill(clipShape);
    g2.dispose();
    }
    
    the problem is that the image grows large from the top lefthand corner
    towards the bottom right hand corner.
    
    What I want is the image to grow from the bottom left hand corner to
    the top right hand corner.
    
    I have tried messing with the Scale instance, but I cant seem to figure
    it out.
    
    anyone know how to do this? thanks!

  - [OT] SourceForge AddReleaseTaskOfftopic: A question about HTTPS / Java:
    
    I'm writing an Ant task to automate the SourceForge 'Add release' procedure.
    For this I'm using Jakarta Commons Net and HttpClient.
    
    The task can be used in an Ant build file as follows:
    
    <taskdef name="sfaddrelease"
    classname="org.xins.util.ant.sourceforge.AddReleaseTask"
    classpath="xins-common.jar:commons-net.jar:commons-httpclient.jar"
    />
    
    <sfaddrelease
    user="znerd"
    password="${password}"
    file="build/xins-${version}.tar.gz"
    group="71598"
    package="71219"
    release="${version}"
    />
    
    The login is done using HTTPS. The Commons HttpClient library supports this.
    But apparently, the server is not trusted, because I get a
    javax.net.ssl.SSLHandshakeException. The message is:
    
    "java.security.cert.CertificateException: Could not find trusted
    certificate"
    
    Apparently, I need to get the certificate of sourceforge.net and store it in
    a keystore. Perhaps I should use 'keytool -import' for this, in some way.
    
    Questions:
    * How do I get the certificate of sourceforge.net?
    * How do I store it in a file so that Java will accept it?
    
    Ernst

  - 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!!

    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

  - 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

  - A specific external package import from javacWhich file(s) are required?
    Where should these file(s) go?
    What's the javac syntax to compile Test16 into ...\class\?
    
    Given this directory structure:
    C:\java\java\jTidy\Test16.java
    C:\java\org\w3c\
    C:\java\class\
    
    Given that Test16.java has this import:
    import org.w3c.tidy.Tidy;
    SSCE @ <http://thufir.lecktronix.net/java/Test16.java>
    
    Here's what I've gleaned from the 'net:
    C:\java> javac -d . org\w3c\* C:\java\java\*
    
    Clearly not correct, but that's my best effort at this point :(
    thank you,

  - JTree with dynamically adjusted row height during editing.I have extended JTable so that the installed editor for a cell checks
    at each keystroke whether it must adjust the row height in order to fit
    the content in the cell. This is easy to do with a document listener
    which just starts a thread on each insertion to check for a height
    change, and then calls setRowHeight on the appropriate row.
    
    However, it does not seem to be so simple to do the same thing with a
    JTree. setRowHeight cannot be called on a specific row, and with
    rowHeight set to 0, the tree cells are only resized when the tree
    manager itself queries the height. There does not appear to be a way
    to get the editor to do this directly.
    
    Does anyone know how to get this effect? It allows for something much
    like a regular text outliner using JTree and I would think lots of
    people would have wanted to do this in the past, but I havent found
    evidence that it has been done.

  - 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.

  - JNI: call C-main program from JavaI have a C-program which calls Java functions through JNI.
    The C-part runs okay, and I want to debug the Java code.
    For that reason, I want to start the Java debugger and then start the
    C-main program through JNI. After that I hope I can set
    breakpoints within the Java part and start debugging.
    
    In the documents I saw that "System.LoadLibrary()" can load
    only DLL's and shared object, but no main-program.
    
    Thanks for any help,

    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.

  - 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.
