  - Thread.run() = static or PircBot != thread safe?Hi there,
    
    After messing about with a few programs I'm now getting into IRC. Because a few
    programs which I used for quite some time now stopped working and because I
    became unhappy with some eggdrop options (and lack off) and suspect it to be
    leaking memory I decided to write up something myself.
    
    One of the main functions of this bot will be performing tutorial sessions. At
    the moment this consists of reading an ascii file which defines what text has
    to be send into the channel. All of this is working decently well (tested with
    System.out.println();).
    
    Because the bot still needs to respond to commands I decided to use a seperate
    class for the tutorial session so I could use a seperate thread. The idea was
    to start a thread which runs the tutorial while the bot still does whatever it
    usually does.
    
    To my pleasure my first approach on threading worked quite nicely. My class
    extended Thread, setup a run() method to define the actual routine to perform.
    In this method I try to send a message to the irc channel the bot is on.
    However, this routine is giving me some errors when I try to compile this:
    
    ./irctutorial.java:47: non-static method sendMessage \
    (java.lang.String,java.lang.String) cannot be referenced from a static context
    PircBot.sendMessage(channel, tutline.substring(tutline.indexOf(' ')+1) \
    trim());
    ^
    1 error
    
    The method which is mentioned here is Thread.run() and to my knowledge this
    method isn't static at all:
    
    ---( irctutorial.java - note; lines have been cut using \ )---
    
    public class irctutorial extends Thread {
    
    ...
    
    public void run() {
    
    String tutline;
    int i = 0, pause = 0;
    File tutorial = new File("/home/peter/tutorial.txt");
    
    try {
    LineNumberReader tutreader = new LineNumberReader \
    (new FileReader(tutorial)); do {
    tutline = tutreader.readLine();
    pause = Integer.decode(tutline.substring(0,tutline.indexOf(' ')));
    Thread.currentThread().sleep(pause*1000);
    PircBot.sendMessage(channel, tutline.substring(tutline.indexOf(' ')+1) \
    .trim());
    tutreader.setLineNumber(i++);
    } while (tutline != null);
    
    ---[ CUT ]---
    
    The error occurs with PircBot.sendMessage() and this I don't understand at all.
    When looking at the PircBot API documentation
    (http://www.jibble.org/javadocs/pircbot/index.html) you can see that the
    'sendMessage' method isn't static either. The method is of:
    
    public final void sendMessage(String target,
    String message)
    
    While the class itself is:
    
    public abstract class PircBot
    extends Object
    implements ReplyConstants
    
    I'm rather new when it comes to using threads and as such a bit confused. Is
    this happening because Thread.run() is indeed static or could this be an issue
    with the PircBot API ?
    
    Thanks in advance for any input you can give me.

  - JNDI issue: XDoclet + WAS 5.1.1Hello all,
    
    I'm having issues trying to deploy an application on WAS 5.1.1. The app
    runs fine on BEA and JBoss servers, but throwing the following naming
    exceptions on WebSphere:
    
    javax.naming.NameNotFoundException: Context:
    <SERVER_PATH>/servers/server1, name: ejb/TestManagerLocal: First
    component in name TestManagerLocal not found. Root exception is
    org.omg.CosNaming.NamingContextPackage.NotFound:
    IDL:omg.org/CosNaming/NamingContext/NotFound:1.0
    
    The bean task for which the reference exception is being thrown looks
    as follows in ejb-jar.xml:
    
    <session >
    <description><![CDATA[TransformationEngine]]></description>
    <display-name>TestEngine</display-name>
    
    <ejb-name>TestEngine</ejb-name>
    
    <home>com.interfaces.TestEngineHome</home>
    <remote>com.interfaces.TestEngine</remote>
    <local-home>com.interfaces.TestEngineLocalHome</local-home>
    <local>com.interfaces.TestEngineLocal</local>
    <ejb-class>com.ejb.TestEngineSession</ejb-class>
    <session-type>Stateless</session-type>
    <transaction-type>Container</transaction-type>
    
    <ejb-local-ref >
    <ejb-ref-name>ejb/TestManagerLocal</ejb-ref-name>
    <ejb-ref-type>Session</ejb-ref-type>
    
    <local-home>com.interfaces.TestManagerLocalHome</local-home>
    <local>com.interfaces.TestManagerLocal</local>
    <ejb-link>TestManager</ejb-link>
    </ejb-local-ref>
    
    </session>
    
    Also, I am using XDoclet to generate all the mappings and interfaces.
    For WAS, it generates ibm-ejb-jar-bnd.xmi, and it has the following
    binding:
    
    <ejbBindings
    xmi:id="Session_bnd_1"
    jndiName="ejb/test/TestEngine">
    
    <ejbRefBindings xmi:id="EJBRefBnd_1"
    jndiName="ejb/TestManagerLocal">
    <bindingEjbRef href="META-INF/ejb-jar.xml#EJBLocalRef_1"/>
    </ejbRefBindings>
    
    <enterpriseBean
    xmi:type="ejb:Session"
    href="META-INF/ejb-jar.xml#Session_TestEngine" />
    </ejbBindings>
    
    Now I'm not sure whether WAS is picking up the binding from ejb-jar.xml
    or ibm-ejb-jar-bnd.xmi, but it appears correctly on the admin interface
    under EJB Bindings. Everything looks okay, but it appears as if
    TestEngine is not able to find TestManager using JNDI lookup. The
    XDoclet tags look as follows:
    
    * @ejb.bean name="TestEngine"
    * display-name="TestEngine"
    * description="TestEngine"
    * jndi-name="ejb/test/TestEngine"
    * local-jndi-name="ejb/test/TestEngineLocal"
    * type="Stateless"
    * view-type="both"
    * @ejb.util generate="physical"
    * @ejb.ejb-ref ejb-name="TestManager"
    * view-type = "local"
    * ref-name = "ejb/TestManagerLocal"
    * @oc4j.bean jndi-name="ejb/test/TestEngine"
    
    Can someone come up with any ideas as I'm totally stuck? Any help will
    be appreciated.
    
    Thanks.

  - Accelerators in one frame being activated from anotherHi.
    
    I have a program that uses multiple top-level frames. One of the frames
    is the "main" one and contains a menu bar and tool bar. The menu items
    in the main frame have accelerators. I want the actions associated with
    these menu items to be activated even if the accelerator is pressed when
    one of the other top-level frames has the focus.
    
    Is there an easy way or accepted idiom to do this?
    
    Thanks,
    
    Cameron

  - JNI: COM event sinks in a DLLhello,
    
    I have created an Event-Sink class in C++ to handle COM-Events and it
    works well in a MFC-application.
    
    But if I create a DLL to use this Event-Sink-Class with the JNI then
    the callback function of the event-sink is not called. The COM-Server
    tells me that it is "overloaded" when it fires the event. It seems to
    me that it "hangs" somehow in the JVM.
    
    here some pseudo code:
    
    in Java:
    
    class Test {
    public static native void nativeFunction();
    public static void main(...) {
    nativeFunction();
    //during sleeping I fire the "event"
    Thread.sleep(30000);
    }
    }
    
    in the DLL:
    
    class EventSink : public IDispatch
    {
    ...
    HRESULT __stdcall Invoke(...) {
    //just exit application
    exit(0);
    return S_OK;
    }
    ...
    };
    
    JNIEXPORT void JNICALL ...nativeFunction(...)
    {
    //initialize COM
    CoInitializeEx(NULL, COINIT_MULTITHREADED);
    //create COM object with CoCreateInstance(...)
    //get IConnectionPointContainer of the object
    //get IConnectionPoint* connectionPoint
    //advise sink to connectionPoint
    EventSink* sink = new EventSink();
    connectionPoint->advise(sink, &cookie);
    ...
    }
    
    what is wrong in the code?
    
    thanks in advance!

  - Best Layout?Hi everyone. I am kind of new to Java in general, much less Swing, but
    I am working on a project where I want to create somewhat of a flow
    chart with draggable boxes and lines connecting them. I plan on
    representing each box in the "flow chart" with a JPanel. Keeping in
    mind that I will need to draw lines between panels, what would be the
    best layout to use? What I am looking for is a layout where I can say
    "put panel A at location (X,Y)" but Sun's explanation of layouts didn't
    seem to explain anything like that. If anyone has any input, I would
    appreciate it.

  - bloking operation in a threadHi !
    I have a poblem with threads : I program multi-threaded applications for a
    short time.
    I would know how it would be possible to stop a thread which is running a
    bloking operation (such i/o functions, server accept(), ...). My app is
    waiting indefinitely for the thread to die and that's normal. so how to
    stop this thread ?

  - Socket open to inavailable IP takes too long timeOn JDK 1.3(I HAVE TO use 1.3.. T.T).
    
    When I open a socket to an IP which doesn't exist(for example
    192.168.34.13 which does not exist), It takes too long time - almost
    5~10 minutes.
    
    I open a socket in a JSP page, when a lot of people try to open the page
    and the IP to connect disapears(it disapears because of network
    problems), the WAS goes down. because of alot of socket connections are
    opened and continue trying to connect too long time.
    
    I just want that the WAS doesn't fail and give customers an error message.
    
    Is it possible to stop socket connection after 10 secs or some secs by
    OS(Unix especially HP-UX) settings?
    
    Or any other solutioin?
    
    Thanks.

  - Eclipse - White space causing all text files to show up as having conflictsWhen we do a CVS synchornization in Eclipse, the Java files work well,
    but ALL (dozens) of text
    files show up as having conflicts, apparently because white space is
    NOT being ignored. When
    we ignore white space on a file by file basis, the conflicts disappear.
    But we have not been
    able to ignore white space globally, so we have to go through our
    dozens of text files one by one, which
    is very tedious and time consuming.
    
    How do we GLOBALLY avoid white space characters causing text files
    looking like they have
    conflicts when doing an Eclipse CVS synchronize.

  - Help with Thread Sleep Calls causing lack of SLEEPHello
    
    I am trying to introduce the sleep() command into my java code.
    
    The existing program runs without the sleep command but I have
    indeterminancy
    I therefore want to send my threads to sleep for different lengths of time.
    
    I have used the following
    
    public void run()
    {
    for (index1 = START; index1<END; index1++)
    {
    try
    {
    sleep(3000);
    }
    catch(InterruptedException e){}
    buf.insert(Pots[index1]);
    }
    }
    
    My problem is that I can get it to compile ok but when I execute it throws a
    whole host of errors.
    
    Can anyone help?
    
    What am I doing wrong?
    
    The only outcome of my current sleep() call is lack of sleep on my part
    
    TIA

  - Problem with GridLayoutHi everybody, I'm having a problem with the layout of my application.
    When I run the following code, I only see one graph in the frame. I'm
    sopposed to see "graphNum" graphs in a row.
    This part of code runs when I press the "draw graph" button:
    
    public void run() {
    Graph[] graphs = new Graph[graphNum];
    JFrame frame = new JFrame();
    for(int i=0; i<graphNum; i++){
    graphs[i] = new Graph();
    SliceVal[] sliceValA = new SliceVal[sliceNum];
    for(int j=0;j<sliceNum;j++){
    sliceValA[j] = new SliceVal(new BigDecimal(10.0),
    colors[j]);
    }
    graphs[i].setSliceVal(sliceValA);
    }
    JPanel grafPanel = new JPanel();
    graphPanel.setLayout(new GridLayout(1,graphNum));
    for (int i=0; i<graphNum; i++) {
    grafPanel.add(graphs[i]);
    }
    frame.getContentPane().add(graphPanel);
    frame.setSize(300, 200);
    frame.setVisible(true);
    }
    }
    
    SliceVal class holds the value and color of a slice of the pie chart.
    Graph class extends JComponent and has a paint() function in it.
    I set the values of slices to 10.0 for simplifying the code
    
    Do you see an error in the code above?
    I would appreciate any help, thank you.

  - in my applet I can't get the stop() and the start() to fireI cannot seem to see when the stop() and start() methnods fire when using
    this applet. I thought when the focus moved away from IE6, the stop would
    fire and then when it got the focus again the start() would fire. Is that
    not the case?
    
    Any ideas on what I could be doing wrong? Thank you.

  - OnLoad kicking off processGood Morning,
    
    A friend of mine asked me a question the other day and I am fairly stumped.
    Is there a way to use the onLoad function to kick off a process on the
    server while the page is being painted? Want to send a message to a servlet
    and then send the form to the servlet once the user has filled in the
    values.
    
    I did some webapp stuff a while back and we used the onload function to help
    the page paint a little easier, I wondered if we could use it to send a
    message, or if there was something in JSP or HTML that I overlooked.
    
    Thanks,

  - JSTL concatenateWell.. i wanna to concatenate a string... like:
    
    String x;
    
    while(true)
    x += "x";
    
    Then i get xxxxxxxxxxxxxxxxxxxx :)
    
    How do i do that on JSTL?
    
    Here is my code...
    
    <c:set var="valorColuna" value="${rowValues.value}"/>
    
    <c:forEach var="pk" items="${datagrid.primaryKeys}">
    <c:set var="pkActual" value="${pk.columnName}"/>
    <c:if test="${colunaActual == pkActual}">
    <c:set var="pkValor" value="${valorColuna}{$valorColuna}"/>
    
    I have tried without operators but it does not work. JSTL functions
    also seem not to help (no concat function!)...
    
    Any sugestions?
    
    Thanks,

  - Embedded underscoresI noticed Ruby has a convention I wish Java would implement. I think
    it could be done without breaking existing code.
    
    You simply permit the _ character to appear embedded in numeric
    literals in Java source code. The lead _ would not be permitted, so
    you still have no trouble telling a number apart from an identifier.
    
    Then you might write a numeric literal like this:
    
    2006_12_31
    or
    123_456_679
    or
    0x1234_5678
    or
    250_361_9093
    or
    1000_99
    
    The _ is simply ignored. You use it to break the number up in
    whatever way you choose to make it more readable.

  - how does picking and intersection works ?hi
    
    I am interested i knowing how does the picking and intersection of shapes.
    I am more concerned about picksegment and shape3d intersection. what's the
    algorithm used and how effective it is. I am interested in the thoery of
    all this than programming.
    
    I am using pick segment to pind the intersection point, I have to find the
    distance and than do some maths to find the intersection point, is there
    an built-in function for this.

  - Apache Derby : create several instances.Hello.
    I am using Apache derby database (Client network).
    I see that when I create table it is created on an instance APP
    (I don't know if instance is the correct word. sorry of my English).
    I see that there are other instances (NULLID, SQLJ, SYS, etc).
    Can I create an instance of my own in derby database, and how can I do that
    ?
    (One instance may be used for repository, another for Datawarehouse, ...)
    
    Another thing :
    If I create several databases for te above reason (repository may be on
    another db), how can I join them, when I am connected to database1, and want
    to run a query that join both tables from database1 and database2 ?
    
    Thanks :)

  - String exceeding length - Getting absolute string lengthHello,
    
    I am having a problem when inputting very long strings into a database.
    The application I am writing can use different databases (thanks to
    the wonders of JDBC) so this issue has been causing problems on both
    Oracle and SQL Server.
    
    Because one of the design objects was to support any JDBC compatible
    database, a concern was raised about text widths. It was therefore
    decided that the maximum column width for a VARCHAR would be a
    configurable value. We theoretically knew that data could be more than
    a single line so we introduced a sequence number to allow multiple
    rows. (Don't ask me why we didn't use CLOBs instead, this is the
    schema I'm stuck with.)
    
    We now need to store base64 data in the same fields. The problem is
    that in an example 4000 characters as defined by the Java string
    object, its physical size is approximently 4430. This seems to be
    because of the amount of mark-up involved, either in the base64 data or
    possibly with the text between.
    
    It occurs to me that while a non-ASCII value many be only a single
    character in a unicode string, it is 6 characters in UTF-8. Therefore
    I'm looking for a way of calculates the absolute length, rather than a
    count of characters.
    
    Is this possible or will I have to change the schema?

    > No. It was added to make source files more readable.
    
    How can something be more readable when anything in effect can be
    replaced by a macro? You are perhaps focusing on #include and the
    like; but the following is bad:
    
    /* In some header file included somewhere while resolving
    a source file */
    #define foo fie
    
    /* In the source file - will end up as fie()*/
    int foo() {
    }
    
    To quote Wikipedia: "The use of preprocessors has been getting less
    common as recent languages provide more abstract features rather than
    lexical-oriented ones. Indeed, the overuse of the proprecessor might
    yield quite chaotic code. In designing a new language based on C,
    Stroustrup introduced features such as inline and templates into C++
    in an attempt to make the C preprocessor less relevant."
    
    > > Yes, again because they avoid strong typing.
    >
    > How?
    
    Because the template has no idea whether the type parameter actually
    supports the operations used inside it, e.g. a method call. In Java,
    you cannot use an operation on a parametrized type unless you declare
    that yes, this type shall conform to this interface/class.
    
    > C and C++ are not strictly typed.
    
    Not C, but every resource I've seen on C++ claims it is (by default),
    though how strong anything is when it can be cast away as will is a
    different question. Maybe you define "strong/strict typing"
    differently from the makers of C++ and Java?

    I am getting the impression "Lisp" is a mis-spelling for "Elitist".
