  - FYI: A new open source/free O/R mapping tool and server page frameworkAnnounce:
    
    A new open-source O/R mapping tool has just been released. There
    are many such programs out there...but this one is very
    special because it's simple (no xml configuration ! yay) and has
    been tested extensively with postgres (and a bit with mysql).
    
    This tool has been used in production enviroments so the
    generated code has most bugs squeezed out by now.
    
    If you have a minute, you can check it out at:
    
    http://www.mollypages.org/dbo/
    
    There's also a server-side page type thingy (like JSP) but with
    much cleaner syntax (and easy typing).
    
    Enjoy !

  - Bug#438188: RFP: schemaspy -- Graphical Database Schema Metadata BrowserPackage: wnpp
    Severity: wishlist
    
    * Package name : schemaspy
    Version : 3.1.1
    Upstream Author : John Currier <email***@***.com>
    * URL : http://schemaspy.sourceforge.net/
    * License : LGPL
    Programming Lang: Java
    Description : Graphical Database Schema Metadata Browser
    
    SchemaSpy is a Java-based tool (requires Java 1.4 or higher) that
    analyzes the metadata of a schema in a database and generates a visual
    representation of it in a browser-displayable format. It lets you click
    through the hierarchy of database tables via child and parent table
    relationships. The browsing through relationships can occur though HTML
    links and/or though the graphical representation of the relationships.
    It's also designed to help resolve the obtuse errors that a database
    sometimes gives related to failures due to constraints.

  - String comparision efficencyHI!
    I have an appliation that will need to parse a text of unkown length.
    I get the data as an array of strings (and thus I know then how much
    data it is)
    I want to do several things on each "row" (that is each element in the
    array) I want to
    1. look for a specific word (start) and count how many of them there
    are in total.
    2. Highlight the word alarm and append a short description to the end
    of the line
    
    my first thought was to use
    
    for(int i=0;i<data.length++){
    if(data[i].endsWith("start"){
    // do the work..
    }else if(data[i].startsWith("Alarm")){
    //do different work
    }
    }
    
    this seems to be rather inefficent as I get two (and possibly more, my
    employer did not seem think these few features were enough..)
    Is there a better way to do this.
    As the alarm line also contains an alarm code, I do not know what it
    looks like. Any suggestions?
    
    regards

  - Dynamic resizing of JPanelDear experts,
    
    I have the a JDesktopPane and a JPanel added to the CENTER and SOUTH
    position of a JFrame respectively.
    
    I would like to dynamically resize the JPanel upon mouseExited like the
    Windows TaskBar.
    
    On mouseExited of the JPanel i set the bounds of the JPanel to a new
    size. However, the sizes do not reflect visually. I have called
    invalidate(), validate(), repaint() and none seems to work.
    
    Other than using JSplitPane to create a resizable JPanel, how can I make
    this work?
    
    Others have suggested using LayoutManagers but which one and how?
    
    Thank you in advance.

  - BZip2-Files & JavaOk two things:
    I'm trying to get the Apache BZip2 Library to work, but I always get a
    NullPointerException. My code looks like this:
    
    [CODE]
    void load(String filename) throws FileNotFoundException, IOException {
    FileInputStream fis = new FileInputStream(filename);
    CBZip2InputStream = new CBZip2InputStream(fis);
    }
    [/CODE]
    
    As soon as the creation of the CBZip2InputStream is reached, a
    NullpointerException is thrown. Why?
    Secondly: if the library is corrupted (e.g. doesn't work stable) is
    there an alternative to it (Googleing did not help me very much)?

  - GUI locking up, but code running fine.I'm using Netbeans 5.0 beta for an IDE, with swing components. The
    situation is something like this:
    
    The program is a board game - the user chooses a building from a panel,
    and then is supposed to get a message to choose what resource to pay
    for it with. Here's a trace of the code:
    
    Game (main object):
    ....
    board[i].activate():
    Game.game.setPlayer(worker);
    Game.game.playerMessage("Choose a wooden building
    from the building panel.");
    Game.game.waitForBuild(type) :
    built = false;
    state = type + Game.BuildWood -
    1;
    
    mainPanel.buildings.getBP().setSelectedIndex(type-1);
    while(!built)
    { Thread.yield(); }
    No problems yet. This works fine, unless a building that needs to call
    chooseResource is selected.
    So, the user clicks one of these buildings, which activates the
    following code, which is where the freeze occurs:
    
    String r = Game.game.chooseResource():
    state = Game.chooseResource;
    resource = "";
    while(resource.length()==0)
    Thread.yield();
    return resource;
    
    Now chooseResource does work in any other context - resource gets set
    by a mouseClicked event handler in a panel out there. But at this
    point, the GUI stops responding. The playerMessage never gets printed,
    and the click event never gets triggered. I did some investigating,
    printing out numbers inside the two inmost loops, and the
    chooseResource loop is continually running. I know the code's ugly,
    but even so, the cause of this behavior is beyond me. Any suggestions
    would be greatly appreciated!

Are you referring to the checkbox icon? That is the little box that is on
the left (by default) and that contains the check mark. The Icon for a
JCheckBox (and for a JRadioButton, too) is a little more aware of its
context than most icons. It looks at the JCheckBox's model and paints
itself differently depending on whether the model is selected.

You can create your own "select-aware" Icon implementation and replace the
icon for the JCheckBox. For an example of how this is done, see one of
the standard checkbox icons, such as
javax.swing.plaf.metal.MetalCheckBoxIcon.

Be aware that this is look-and-feel dependent, so even if your icon looks
fine with one L&F, it may no look so good if the user changes the L&F.
Unless you are in control of the L&F, you may need to consider this.

  - How to get mozilla to download a jar file?
    
    I can download jar files without difficulty using Internet Explorer,

    Does anyone know how to configure Mozilla to download jar files
    and save them to disk?
    
    Or is this a server-side problem? (FWIW, I noticed that the server
    serving the jar files in question put "text/plain" in the Content-Type
    field.)

  - Problem with RMI in LinuxI'm a newbie in the RMI programation.
    I downloaded the sample code in Java tutorial in java.sun.com and
    tried to compiled it. First, I compiled the interface class and was
    going to compile the stub and skeleton. However, after typing "rmic -d
    . engine.ComputeEngine" the following exception appeared:
    
    ComputeEngine_Stub.java:40: error:Syntax error: found '{'
    java.lang.Exception: exited with errorcode 1

  - Need help creating a grid.Hello I am new to Java AWT/Swing and have a question.
    I would like to create a 10x10 grid, where each "cell" can handle mouse
    events. So if I click on cell with a coord A4 then it would change color.
    I was thinking of using JButtons but I want the "cells" to look more like
    Excel-like in appearance. I also found a component called JTable but I do
    not think that it can handle mouse events. Any suggestions??

  - retrieving CPU Usage and Memory Usage information in JAVAHi All,
    I 've been searching through this group for information on CPU and
    Memory usage retrieval on Windows machine using JAVA. After following
    so many previous threads on the same subject, the possible solution I
    've observed was using JNI calls to native libraries for these OS
    specific information retrieval.
    Later I found that java management libraries already has it, native
    libraries and some jmx classes.
    
    Sharing the code, hope this may help group members in their
    requirements.
    
    Code:
    com.sun.management.OperatingSystemMXBean mxbean =
    
    (com.sun.management.OperatingSystemMXBean)
    ManagementFactory.getOperatingSystemMXBean();
    
    System.out.println("********* CPU & MEMORY USAGE OF \\harsh
    *********");
    System.out.println("OS : "+mxbean.getName());
    System.out.println("Available Processors :
    "+mxbean.getAvailableProcessors());
    System.out.println("Commited Virtual Memory :
    "+mxbean.getCommittedVirtualMemorySize());
    System.out.println("Free Physical Memory :
    "+mxbean.getFreePhysicalMemorySize());
    System.out.println("Free Swap Space Size :
    "+mxbean.getFreeSwapSpaceSize());
    System.out.println("Process CPU Time : "+mxbean.getProcessCpuTime());
    System.out.println("Total Physical Memory Size :
    "+mxbean.getTotalPhysicalMemorySize());
    System.out.println("Total Swap Space Size :
    "+mxbean.getTotalSwapSpaceSize());
    
    Problem:
    getProcessCpuTime() method returns the CPU time used by the process on
    which the Java virtual machine is running NOT the '%CPU Usage' time
    which i was hoping to get.
    
    If anyone is having idea about how to obtain '%CPU Usage' of windows
    machine using java program, kindly post the message.

  - Offset not calculated properlyI'm trying to move a second window so that it is directly above another,
    hugging it closely. I'm using the below code, but for some reason, its not
    always consistent.. sometimes my second window falls just below the title
    bar, sometimes its pretty far below the title bar.
    
    void resetPositionComboTD()
    {
    Point loc = this.getLocationOnScreen();
    
    int newY = loc.y - sw.getHeight();
    int newX = loc.x;
    
    sw.setLocation(newX, newY);
    }
    
    I tried playing with insets, but no matter what I did, it didn't seem to
    help much (or at all)
    
    Any help is appreciated, I'm driving my self nuts with this

  - JDBC QuestioComing from the world of VisualBasic, I'm not find Java too hard to catch on
    to. After just a couple of weeks of real coding, I'm even cranking out some
    code to access a MySQL database. I've got something of a conceptual hill to
    jump over, and that's about the Statement class. In VB, I'm used to using
    ADO, and just opening a connection and then running queries against it
    (either record sets or update-style queries). Is it just the case that any
    code I'm translating I just need to insert the lines dealing with the
    Statement class, and that's it? What is the purpose of Statement?
