    Devel is ripe for splitting ala the x11-* categories. And I suspect a
    not insubstantial portion of devel could be moved elsewhere (e.g.
    devel/mime -> mail/mime).
    
    And this whole thread should be moved to the ports list. Please note
    the reply-to.

  - Registering Connector/J driverHi. I have
    - mySQL 1.4
    - Connector/J 3.0.15
    
    I want to use Java to query mySQL database via Connector/J.
    
    Connector/J documentation at
    http://dev.mysql.com/doc/connector/j/en/index.html instructs to
    compile and run the following Java code to register the Connector/J
    driver:
    
    import java.sql.Connection;
    import java.sql.DriverManager;
    import java.sql.SQLException;
    
    // Notice, do not import com.mysql.jdbc.*
    // or you will have problems!
    
    public class LoadDriver {
    public static void main(String[] args) {
    try {
    // The newInstance() call is a work around for some
    // broken Java implementations
    
    Class.forName("com.mysql.jdbc.Driver").newInstance();
    } catch (Exception ex) {
    // handle the error
    }
    }
    }
    // Error:
    // SQLJConnectorRegister1failed.java:8:
    // class LoadDriver is public, should be declared in a file named
    // LoadDriver.java
    
    Where should I have this LoadDriver class/java file? It doesn't come
    with any of the packages I have (java.sql.* or connector/J driver
    classes). Hence I can't "supply a class that implements Driver
    interface" which would I gather register the driver. I have set the
    classpath to the driver's jar, so it should find that class.
    
    *
    And then SQL queries would be possible. That would be an achievement
    as such, never loaded/registered a driver in my life, or programmed
    much anyway.
    
    Appreciate any help over this.

  - bypassing IISHi
    
    We have an architecture where users log in to their
    "windows" pcs using Microsoft Active Directory
    and requests are then sent as follows:
    
    client -> IIS -> Tomcat
    
    An isapi redirector resides at IIS which forwards the request to
    Tomcat.
    
    isapi redirect would appear to populate the HTTP header with
    the user's credentials.
    
    My question is: how can we avoid the overhead of IIS
    and send requests directly to Tomcat for authentication against the
    ldap server as before.
    
    (The issue I see is how to populate the HTTP header with the
    user details?)

    FWIW, I've only ever seen "pack" called before "show" - it is called once
    in the lifetime of the frame. However, validate can get called at any time.
    I'm not entirely sure why this is the case, however.

  - POSSIBLE SECURITY PROBLEM in Java 5!This happened accidentally, but an attacker might use this
    intentionally in a hostile applet to perpetrate a denial of service
    attack.
    
    I had a Java app compile and run that generated ~200 threads accessing
    the network. It suddenly stopped functioning; it hadn't hung -- the UI
    still worked -- but the network activity dropped to zero and it
    wouldn't do anything. (Picture a Web browser that works, except every
    attempt to go to a page produces a timeout or the browser just spins.
    Sort of like that: the UI is working but the backend isn't.)
    
    Naturally, suspecting a bug, I exited and went to rerun the app, this
    time attaching a debugger process. Failed. Eclipse showed "Launching
    (83%)..." and stuck there. Details showed "searching for free socket"
    or some such.
    
    At this point I discovered that almost every other network using app on
    the system had locked up. Shareaza, MSN messenger, etc. -- Firefox was
    the only survivor, and it would not function (see above description of
    semi-functional Web browser; this was Firefox after the accident).
    
    Task Manager showed two Java tasks, one with over 100 threads;
    presumably the app that was supposed to have exited. I repeatedly
    attacked it with "End Process" and "End Process Tree"; no effect.
    Eclipse, when exited, likewise remained as a headless zombie: no
    visible UI but still an Eclipse process and a Java task with a couple
    of threads. Neither could be killed.
    
    After over half an hour, none of the tasks had exited that had been
    told in various increasingly imperative ways to terminate, and the
    network remained unusable. I concluded I had to reboot.
    
    To top it off, a clean reboot wasn't possible -- the system would close
    a couple apps then just sit there. I had to power-cycle the fucking
    box! This on an NT kernel OS and with the trigger being Java, the
    paragon of security and non-crashingness? What the fuck?!
    
    Now I've lost all my open Explorer folders and various other
    inconveniences can all be laid at the doorstep of ... whatever the fuck
    it was that happened.
    
    Can anyone explain this event? Opening a lot of network connections
    shouldn't be a problem on XP, and it sure as hell shouldn't render the
    system unusable to the point of forcing a cold boot. Even if the Java
    app ate all the free network sockets, it should have been terminatable,
    and killing it should have released the sockets. Even terminating other
    tasks (such as the nonresponsive Shareaza) that used the network didn't
    free any up (Shareaza, when end-tasked, disappeared promptly from all
    task and process lists, but Firefox didn't magically start working
    again).
    
    Annoyingly, the system help also stopped working(!); I was desperate
    enough to actually resort to Help and Support Center to find info on
    terminating processes and/or freeing sockets, given that the usual
    first-resort, Google, was rendered unavailable by the problem.
    
    This Should Not Have Happened.
    
    We have at least 3 separate problems:
    * Java can do things that DoS a Win32 box, without doing anything but
    open sockets.
    Applets can open sockets (though only back to the originating site);
    Win32 boxen are
    extremely commonplace. You do the math.
    * Windows XP SP2, with all the latest updates (including and especially
    security updates),
    allows a single app to hog all the network sockets, and apps that
    want a socket but
    can't get one seem usually to hang rather than gracefully report an
    error condition to the
    user.
    * And it does not seem to properly "terminate with prejudice" an
    unresponsive process or
    free up resources one had when it does terminate it successfully. Is
    there no equivalent of
    "kill -9", via Task Manager or otherwise, even when you're logged on
    as administrator?
    
    It looks like some problems (can't kill processes, processes can kill
    parts of the system's overall functionality, killed tasks don't always
    have their resources released by the OS) from the bad old days of
    Windows 3.1 are still present and accounted for...
    
    Win32 SP2 with all security fixes;
    JDK/JRE 1.5.0_06 (latest, as of a couple weeks ago anyway)

    How could it throw the 4 exceptions? Only one exception may be thrown
    by a method at runtime, but not 4 at once.
    I suspect that the *compiler* refuses to compile your code because the
    method *might* throw one of these 4 exceptions, and you don't catch
    them or rethrow them.
    Since the call should never throw any of the exceptions (the class
    name returned by getCrossPlatformLookAndFeelClassName() being of
    course perfectly valid for any platform), I suggest you just catch
    them and rethrow them as a runtime exception:
    
    try {
    
    UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
    }
    catch(ClassNotFoundException e) {
    // should never happen
    throw new RuntimeException(e);
    }
    catch(InstantiationException e) {
    // should never happen
    throw new RuntimeException(e);
    }
    catch(IllegalAccessException e) {
    // should never happen
    throw new RuntimeException(e);
    }
    catch(UnsupportedLookAndFeelException e) {
    // should never happen
    throw new RuntimeException(e);
    }

  - OutOfMemoryError problemHi,
    
    I am a user of cruisecontrol ( continuous integration server). As long
    as I have used it I have had problems with
    java.lang.OutOfMemoryError's. I have gotten numerous ideas on how to
    handle it. Some
    resonable and some more unrealistic. However lately I dicided that I
    need to dig deeper into this.
    I use two ways to perform build and test. Both ways use the same 'ant'
    and the same 'build file'.
    The difference is in how the build is triggered.
    
    Shell script
    =========
    
    Here I use a shell script to start ant.
    java -Xms512M -Xmx756M -classpath .......
    
    Cruisecontrol
    ==========
    
    Here I start cruisecontrol ( a java program) that starts ant.
    I set Xms and Xmx for cruisecontrol as well as ant.
    
    When I execute the shell script the 'junit' and 'junitreport' tasks
    execute nicely.
    
    On the other hand when I execute 'cruisecontrol' I get a
    java.lang.OutOfMemoryError when I execute the 'junit-report'.

    I did some investigation in ant ( source code ) and found out the each

    There are two steps in the code. Step 1 works ok! Step 2 is failing
    siince the big merged file is not complete. Could it be something with

    Document doc = builder.newDocument();
    Element rootElement = doc.createElement(TESTSUITES);

  - XML Validation with JavaHi
    
    For several days I've been trying to validate a very simple XML-Document
    against an XML Schema - so far without success. I've tried several
    approaches, using libraries like Xerces, JAXP and an Oracle-library, but
    none of those worked the way for example XML Spy works.
    
    Here is my Schema:
    
    <?xml version="1.0" encoding="UTF-8"?>
    <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <xsd:element name="root"/>
    </xsd:schema>
    
    This is the (invalid) XML-File that references the schema: <?xml
    version="1.0" encoding="UTF-8"?> <root
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation='test.xsd'> <a></a> </root>
    This is my first try to validate the Document against the schema:
    
    try { DOMParser parser = new DOMParser();
    parser.setFeature("http://xml.org/sax/features/validation",true);
    parser.setFeature("http://apache.org/xml/features/validation/schema",true);
    parser.setFeature("http://apache.org/xml/features/validation/schema-full-che
    cking",true); parser.parse("C:\\test.xml"); }
    catch(Exception ex) { ex.printStackTrace(); }
    
    This runs without problems, however, it doesn't report a validation-error.
    
    My second try:
    
    try { SAXParserFactory parserFct =
    SAXParserFactory.newInstance(); parserFct.setValidating(true);
    parserFct.setFeature("http://xml.org/sax/features/validation", true);
    parserFct.setFeature("http://apache.org/xml/features/validation/schema",
    true);
    parserFct.setFeature("http://apache.org/xml/features/validation/schema-full-
    checking",true); javax.xml.parsers.SAXParser parser =
    parserFct.newSAXParser(); parser.parse("C:\\test.xml", new
    MyHandlerBase()); } catch(Exception ex)
    { ex.printStackTrace(); }
    This is the Errorhandler I used:
    
    class MeinErrorHandler implements ErrorHandler{ boolean b = false;
    public void warning(SAXParseException e) throws SAXException {
    System.out.println("WARNUNG: " + e); b = true; } public void
    error(SAXParseException e) throws SAXException {
    System.out.println("FEHLER: " + e); b = true; } public void
    fatalError(SAXParseException e) throws SAXException {
    System.out.println("LEIDER, LEIDER, AUS: " + e); } public boolean
    warninghappened(){ return b; }}
    
    Again, no validation-error.
    
    My third try:
    
    InputSource is = null; DOMParser parser = new DOMParser();
    Document doc = null; try {
    parser.setFeature("http://xml.org/sax/features/validation",true);
    parser.setFeature("http://apache.org/xml/features/validation/schema",true);
    parser.setFeature("http://apache.org/xml/features/validation/schema-full-che
    cking",true);
    parser.setProperty("http://apache.org/xml/properties/schema/external-noNames
    paceSchemaLocation", "C:\\test.xsd" ); is = new
    InputSource(new FileReader("C:\\test.xml"));
    parser.parse(is); } catch(Exception ex)
    { ex.printStackTrace(); }
    
    Again, no validation-error.
    
    My fourth try involved the oracle.xml.parser.schema and
    oracle.xml.parser.v2-packages.
    Here is the code:
    
    public void process(String xsdURI, String xmlURI) throws Exception
    {
    XSDBuilder builder = new XSDBuilder();
    URL url = createURL(xsdURI);
    // Build XML Schema Object
    XMLSchema schemadoc = (XMLSchema) builder.build(url);
    DOMParser dp = new DOMParser();
    url = createURL(xmlURI);
    // Set Schema Object for Validation
    dp.setXMLSchema(schemadoc);
    dp.setValidationMode(XMLParser.SCHEMA_VALIDATION);
    dp.setPreserveWhitespace(true);
    dp.setErrorStream(System.out);
    try
    {
    System.out.println("Parsing " + xmlURI);
    dp.parse(url);
    System.out.println("The input file <" + xmlURI + "> parsed
    without errors");
    }
    catch (XMLParseException pe)
    {
    System.out.println("Parser Exception: " + pe.getMessage());
    }
    catch (Exception e)
    {
    System.out.println("NonParserException: " + e.getMessage());
    }
    }
    
    This worked fine with the test.xml-Document, however, when I tried to
    validate a more complex document which used keys and key-references, it
    couldn't validate the Document although XML-Spy had no problem with it.
    
    Am I missing something here? Does anybody know those problems and has a
    solution for it, or perhaps a sample-code that works? Any help would be
    greatly appreciated.
    
    Thanks in advance

  - KeyRelease Event affects next Internal FrameHi,
    I am working on an MDI application using JInternalFrames. I have
    forms to fill that have the 'Next', 'Back' and 'Cancel' buttons. I am
    assigning key presses (Enter, Alt+left and Esc respectively) through
    KeyRelease event. In addition, the 'Next' button is assigned as the
    default button using
    this.getRootPane().setDefaultButton(btnOK). However, I find that when
    I run the program and press the Enter key, after accepting the enter
    and processing the button action, it loads the next JInternalFrame and
    appears to call the KeyRelease event for this form too. Since I have
    entries that must be filled, this raises errors that entries are not
    filled.
    Can anyone tell me what I am doing wrong.
    Thanks in advance,

java-programmer, Little problem with ant install task Hi,

I found out that i can use ant for installing my web application.
great, I have copied some code from an example and added the taskdef's
to the top of my build.xml.
Then I copied the catalina-ant.jar into my java classpath.

But when I run it, I get :
"A class needed by class org.apache.catalina.ant.InstallTask cannot be
found: org/apache/tools/ant/Task"

I looked into the catalina-ant.jar and could not find a Task class
indeed, but then, where is it...?

Taskdef:
<taskdef name="install"
classname="org.apache.catalina.ant.InstallTask" />
<taskdef name="remove"
classname="org.apache.catalina.ant.RemoveTask" />
Target:
<target name="install" depends="war" description="Install servlet
on tomcat.kochan.de">
<install url="${tomcat.url}" username="${manager.username}"
password="${manager.password}" path="${app.path}"
war="jar:file:/${war.dir}/${project}.war!/" />
<sleep seconds="2"/>
</target>

Thanks for help!

java-programmer >> Little problem with ant install task Hello Werner,

org.apache.tools.ant.Task is probably installed somewhere in tomcat.
Otherwise, you need to download ant from ant.apache.org.
The Task class is in the ant.jar file.

Hopes this helps.

If you have more problems, mail user at ant dot apache dot org.

Cheers,

Antoine

  - best approach for transaprent boxes
    I'm hoping for some guidance on the best way to do the following, since I am fairly new to the Java language.
    I am building an applet that uses a canvas to show a map (awt only - no swing). I want to display semi-transaparent boxes over the top of the map to show things like status, or have options, and the boxes should be able to process mouse events. The canvas is using a double-buffered strategy and uses Graphics2D.
    
    My first thought was to simply design lightweight components - but they require a container, which the Canvas is not.
    So then I thought I would extend the Canvas class to work with another completely custom "decorator" class that would be able to buffer the area of the canvas it covers for quick updating if it changes, and draw it's own info on top - but I just can't figure out how to grab a part of the rendered parent canvas to store offscreen and paint again later.
    
    So my question is: Is the second method a good way to go about this, or is there a better "Java" way of doing this (I'm still probably thinking in a Delphi mindset)? And if the second way is ok, then how do I buffer just part of the parent canvas?

  - Mac version of IE tires to download sounds rather than playing them.
    
    I've done a web site which encorporates javascripted sound behaviors.
    
    On the PC version of Internet Explorer they do what they're supposed
    to do. That is, play the sound on both "mouse over" and "mouse up"
    events.
    
    On the Macintosh version of IE it triggers off an automatic download
    attempt. I have also seen this on some PC's running Netscape, but
    rarely.
    
    Opera doesn't even seem to do anything with the sound events on the
    Mac. The PC version of Opera seems to work correctly.
    
    So, my question: is there a way to code this using Dreamweaver or
    some other authoring program, so it can be controlled on these
    different combinations of browsers, and Computer Platforms?
    
    I've found this most frustrating.
    
    Thanks for any help you might give on this.

  - Cannot draw on mutable imageHi,
    
    I got a problem with drawing on an image created with the
    createImage(int width, int height) method. I use MIDP 1.0 and
    everything works fine in the emulator. But when running it on my
    T-630, I just get a white image with the defined size. It doesn't
    matter what I draw on the Graphics-object, my phone just displays a
    white rectangle.
    The code should be ok, since it works in the emulator. I also used
    several examples from the internet - all with the same result.
    
    Any ideas what might be wrong?
    
    Thanks in advance

  - Basic java program structure; Was: Problems with multidimensional arrays and global variables<top posting seemed more appropriate for this post>.
    
    Being a Java newbie and having been struggling with the basic concepts of
    the structure of a java program (as well as "static") I would like to say
    that this is the best example I have seen so far of the basic form of a java
    program. Nice, simple and after reading it I think I finally understand
    what is going on. I have read far too many books and examples that seem to
    enjoy obfuscating the concept they are trying to explain with way too many
    extraneous details.

  - SourceDataLine ProblemA while back I implemented sound using javax.sound.sampled into my Tandy
    Color Computer 2 applet.
    
    The Color Computer had a 6-bit DAC used to generate audio. I basically
    take the values written to the DAC and then feed them (although at a
    much higher rate) into a SourceDataLine.
    
    The problem is that the sound can crackle or break up depending on the
    program emulated. I can prevent this by either feeding the data to the
    SorceDataLine at a higher rate or by reducing the sample rate on the
    AudioFormat. Both of these methods fix the breakups but then the pitch
    drops enough that the sound is no longer accurately emulated.
    
    I just don't understand the workings of javax.sound.sampled well enough
    to figure out a workaround for this problem - it seems like it should be
    possible.
    
    Any ideas?

  - use my JSP custom tag on click of buttonI have written a custom tag in a jsp
    
    <test:attribs attribNames="<%=aenum%>">
    <li> <b><%=aenum.nextElement()%></b>
    </test:attribs>
    
    It lists the request attributes.
    
    Now i want the to list the same on click of a button or say on clicking
    on an image( or consider for some specified event of a HTML component)
    
    Can i use the custom tag for the same and if yes how?

  - Using a JList with a cell renderer within an applet/cell renderer not workingI have a cell renderer for a JList that is supposed to render the foreground
    color in blue, and also insert tabs into the lines. When this code is
    changed to run as an application, the cell renderer performs as expected.
    When the code is run as an applet, the cell renderer has no impact at all.
    
    Any help would be appreciated.
    
    I am using SDK 1.4.0, Windows XP Professional.

  - Server-side tools surveyI'm currently working with JBoss/Tomcat, PostgreSQL, NetBeans, Struts,
    XDoclet, Ant, JUnit, JUnitEE...and a few things I've probably forgotten
    to mention.
    
    What tools do *you* consider necessary for web application development?

    Does it mean MS Access does not have a concept of a BD, since it is
    kind of a file base Data Store?
    
    There is also something I don't quite know how to interpret.
    
    When you ask the JdbcOdbc driver for Catalogs it gives you
    
    . . .\Office\Samples\ADDRBOOK
    . . .\Office\Samples\CONTACT
    . . .\Office\Samples\INVENTRY
    . . .\Office\Samples\Northwind
    
    even if you declare the a USer DSN only to
    
    . . .\Office\Samples\Northwind
    
    Experimentally I dropped a copy of
    
    . . .\Office\Samples\Northwind.mdb
    
    in
    
    . . .\IDS\File\examples
    
    and set up a system DSN to got IDSExamples.mdb
    
    However, while query the DBMS for catalogs, I got
    
    . . .\IDS\File\examples\IDSExamples
    . . .\IDS\File\examples\Northwind
    
    Does it mean Access considers the folder containing the '.mdb' file
    as sort of a 'schema'?
    
    How could u still create a Database using JDBC in a MSAccess DB?
