  - Applet won't work on the Internet, yet it works on my hard drive!!!Hi!
    
    I have uploaded this (first in my life) applet on the Internet, along with
    the HTML file for its viewing. On my hard drive I've opened the HTML with
    Internet Explorer and Opera, and it works ok. Then I uploaded it on the
    internet, and when I opened the Web site I got an "Invalid bytecode" message
    in Opera. I've contacted the owner of the site and he says he has also
    downloaded my html and .class on his hard drive and it ain't working for
    him.
    So what am I doing wrong? Is it that I have compiled with Java 1.4.1? I've
    also uploaded the files on another web space provider, and it didn't work
    there either.
    
    This is the url:
    http://www.freewebs.com/csabaland/java/pogadjanje_reci.html
    
    You can also download the .class and .java, which is reci.java, and check it
    out yourself.
    
    Can someone tell me why isn't this working?

  - [PATCH] jdk1.4.2, getsockname(), and ECONNRESET
    --Apple-Mail-4--662330866
    Content-Type: multipart/mixed; boundary=Apple-Mail-3--662330884
    
    --Apple-Mail-3--662330884
    Content-Transfer-Encoding: quoted-printable
    Content-Type: text/plain;
    charset=ISO-8859-1;
    format=flowed
    
    In j2se/src/solaris/native/sun/nio/ch/Net.c, getsockname() is called to=20=
    
    determine the local address and port of a socket.
    
    Under both Linux and Solaris, getsockname() will only fail if invalid=20
    arguments are provided. If getsockname() returns an error, Java throws=20=
    
    a java.lang.Error.
    On FreeBSD, getsockname() will also return an error with errno set to=20
    ECONNRESET if the connection has been reset by the peer. Consequently,=20=
    
    Java throws a java.lang.Error.
    
    The only way to handle this without an API change is to check for=20
    ECONNRESET; In the attached patch, if errno is set to=A0ECONNRESET we=20
    fill in the sockaddr structure with a port of 0, an IP of INADDR_ANY,=20
    and clear out the error.
    
    Also, any comments on the thread-safe resolver patch?
    
    Thanks,

  - Jaxb and xsd Help requestedHi,
    I'm having problems compiling the classes generated by Jaxb when using
    the schema below. (Note the xsd below is part of a bigger xsd file i
    just pulled out the section that was giving me issues ). If anyone can
    see a problem with the xsd defined below I would appreicate the
    information.
    
    The inner interface defined within the generated java class is causing
    me issues. The error I get is "Nested type GuestCountType hides an
    enclosing type". i would appreciate any help with this.

  - Smoking assertions?With regard to assertions it appears that the compiler default has
    changed from 1.4 to 1.5. The 1.5 default compiles as-if "-source
    1.5" instead of the old 1.4 way "-source 1.3".
    
    All well and good but 1.5 doesn't appear to let me compile with
    "-source 1.3" to have an identifier named "assert". Apparently you
    could do this with 1.4. If I try to 1.5 compile with "-source 1.3"
    it returns the error that "assert is a keyword, try compiling
    with -source 1.4, blah blah".
    
    Does anybody know if this is correct and why they removed the
    ability to compile as 1.3?

  - jdk 5 generic, why not the other way arround for (T[] e, Collection<T> c)Hi,
    
    I'm trying to understand the generic concept. The following confused
    me:
    
    public static void main(String arg[])
    {
    Object[] oa = new Object [10];
    Collection<Object> co = new ArrayList<Object>();
    
    String[] sa = new String[10];
    Collection<String> cs = new ArrayList<String>();
    
    method(sa, co); //1
    method(oa, co); //2
    
    method(oa,cs); // 3, compile error:
    //<T>method(T[],java.util.Collection<T>) in Test cannot be applied to
    // (java.lang.Object[],java.util.Collection<java.lang.String>)
    // method(oa,cs);
    }
    
    static <T> void method(T[]e, Collection<T> c)
    { //do nothing }
    
    The #2 is obvious, but why #1 is ok and #3 is wrong?

  - SAX with JAXPHi,
    
    I want to parse a XML document with SAX (using JAXP) and found lot's of
    examples of parsing from a file. But... I have the XML in a String variable
    and want to parse from there. All the 'parse' methods from the SAXParse
    class receive a File, or a InputStream, or a URI... I don't want to create a
    file just to be able to parse the XML (for performance reasons).
    Any help appreciated,

  - ROW ID problemHi,
    I am wtiting JAVA application and getting datas from MS SQL.
    This is the code:
    
    QueryDataSet ds = new QueryDataSet();
    ds.setQuery(new com.borland.dx.sql.dataset.QueryDescriptor
    (db,"select * from myTable"));
    
    In myTable there is one column defined as "primary key".
    But dataset(ds) does not get rowID automatically. I have
    to disable updateRowID in MetaDataUpdate for dataset, and
    then set rowID to the column manually
    
    I had no problem in Sybase, but now I have changed to MS
    SQL. Any idea? May be it is some connection property I
    have not checked out?
    
    Thanks beforehand.

  - How to make CLASSPATH behave like PATH on Windows?Windows (XP and NT) allows one to specify environmental variable
    (such as PATH and CLASSPATH) at both the SYSTEM-wide level
    as well as at the per-USER level.
    
    And the behavior has always been that the value of one's PATH list is
    the concatenation of those two ENV specifications.
    
    So, the $64 question is: Is there some way to coerce the resulting
    CLASSPATH list to also be a concatenation of both the SYSTEM
    and the USER's lists?
    
    (Hopefully, some sort of registry hack can accomplish this!?)
    
    The reason I ask is that today, after installing a Sun 'product' called
    JMF (Java Media Framework), it BROKE my existing CLASSPATH
    setup. The reason it BROKE it was that BEFORE the installation,
    I had my CLASSPATH defined (only) at the SYSTEM level, and it
    got inherited into my USER level. But, the (stupid?) JMF kit decided
    to 'add' some stuff of its own to the USER classpath, and since one
    didn't exist at all, it created one and put its stuff in it.
    
    BUT the unwanted side-effect of that (brilliant?) idea was that now
    the only resulting CLASSPATH that the users have is this new one that
    the kit created and all the existing entries on the SYSTEM-wide defn
    of CLASSPATH now get tossed into the bit-bucket.
    
    Any SUN Java architects out there who can rule on this? Is this a
    bug or a feature of the JMF kit? (A registry hack or something similar
    for a workaround would be nice.)
    
    Cheers...

    prefix="my_web2" suffix=".log" resolveHosts="false" pattern="combined"/
    >
    </Context>
    </Host>
    
    Everything is working as it should, except that when I hit www.mysite.com/Web1
    or www.mysite.com/Web2 the only log that gets updated is
    mysite_access.
    
    Can someone please explain to me how to go about writing to the
    my_web1.log and my_web2.log files for those applications?
    
    Thanks,

    v.add(DateWrapper.toString(sr.getDate()));
    v.add(sr.getMachine());
    v.add(sr.getUser());
    v.add(sr.getMessage());
    
    data.add(v);
    }
    
    // Need to set the data model for the table.
    DefaultTableModel tModel= new DefaultTableModel();
    tModel.setDataVector(data,columns);
    JTable jt= new JTable();
    jt.setModel(tModel);
    
    return jt;
    }
    
    This compiles fine but when I run it, I get all of my data, but no
    column headers!
    
    Any ideas?
    
    Thanks,

java-programmer, java front end that creates database apps Does there exist a java front end like this database admin tool:
http://qform.sourceforge.net/
but that also allows you to create database applications (similar to
Rekall if you are familiar with that, uses python)
ie. allows you to create your own forms for data input input etc,
provides reporting, scripting etc

Thanks

  - Problem with TableDear all,
    
    I have a TextField and a TextFieldHandler implement ActionListener and
    a Table.
    
    How can I do the following function?
    
    When the user type 111 in the TextField and press enter, item 111
    information is retrieved from database and will be displayed in the
    table.
    When the user type 222 in the TextField and press enter, item 222
    information is retrieved from database and will be displayed in the
    table.
    
    ( I know how to detect the value entered in the TextField, but I donno
    how to display the corresponding information with a Table)
    
    Thanks for reply.

  - importing Java-code into Rational Rose RealTimeIs there anyone who has managed to get existing java-code imported into

    The documentation shipped with Rational Rose is very spartan on that topic

    2D CD E7 2B
    
    and I feed it into a BigInteger so that I can do simply compares and
    easy formatting. However, when I call the toString(16) I get
    
    74 0d 66 82 98 0e 83 ea 4d 66 d3 d1 cc 22 39 9a d2 32 18 d5
    
    I am sure, in it's own way, it is "right" but I need to understand why
    this is occurring. Since these values represent hashes I will be for
    sure asked by they are the same as what was recorded for them.

  - servlet communicationi`m using servlet technology in a very unusual way and i`m now
    searching for a better solution:
    there is a server, a embedded device and a user, which logs onto the
    server, for access to the embedded device. the server now calls the
    embedded device via gsm, to tell the embedded device to connect to the
    internet and callback. after that, the data from the embedded device is
    transfered to the server and displayed as a html-file. this is now done
    via polling the application context, where all online-devices are
    stored.
    problem now is: i want to figure out a better way, how to get the
    server or rather the html file, which is refreshed every 15 seconds, to
    see if the device is online now, to know.
    is there some way to exchange the data between this servlets?

  - NIO! Nein!I recently had the misfortune of trying out a InputStream.available()
    command, only to find out it doesn't work on sockets.
    
    I've found that the solution to my problem is the Nio SocketChannel
    class, and now I have only one question:
    
    What was Sun smoking when they came up with SocketChannel and where can
    I get some?
    
    SocketChannel* and the SSLEngine is probably the most complicated way of
    doing socket work and I can only wonder whose crazy idea it was.
    
    Why couldn't they just make .available() work as advertised?
    
    *sigh*
    
    Just wanted to publically complain about unncessary complication.

  - JTables and dynamically adding dataHey,
    I have a JTable that I want to add a new column to every time someone
    clicks a button. I have been reading about extending the
    AbstractTableModel, but I don't how this allows you to add a new
    column. The examples online show what happens when a user edits a
    table, but I don't want that. I want it add when the user presses a
    button outside of the table. Some advice would be appreciated.
    
    Thanks

  - Java Native Interface: "Translate" java call to JNI, how to pass parameters, how to show exceptionHallo,
    
    I am at least one step further, now I need to pass the properties to
    the call and are now sure how:
    
    Remember: The call I want to implement in Delphi is
    java -Xmx256m -cp
    "lib\fop\fop.jar;lib\fop\avalon-framework-4.1.3.jar;lib\fop\JimiProClasses.zip"
    org.apache.fop.apps.Fop -fo "Data.xml" -c "lib\fop\Config.xml" -pdf
    "Data.pdf"
    
    So the parameters that have to be passed are:
    -fo "Data.xml"
    -c "lib\fop\Config.xml"
    -pdf "Data.pdf"
    
    If I do
    JNIEnv.CallStaticVoidMethod(Cls, Mid, ['-fo "Data.xml" -c
    "Config.xml"-pdf "Cover.pdf"']);
    (all parameters in one string) or
    JNIEnv.CallStaticVoidMethod(Cls, Mid, ['-fo "Data.xml"', '-c
    "Config.xml"', '-pdf "Cover.pdf"']);
    (each parameter in a separate string)
    
    ...then JNIEnv.ExceptionOccurred is not NULL after the call, thus some
    exception occured.
    
    The parameter Args in the call CallStaticVoidMethod() is an array of
    const. In CallStaticVoidMethod() the array elements are converted to
    JValues with ArgsToJValues().
    The exemplary C++ code in the doc PDF works with an ObjectArray created
    with NewObjectArray(). I tried that, but CallStaticVoidMethod() won't
    accept an ObjectArray, nor would the similar procedures
    CallStaticVoidMethodA() or CallStaticVoidMethodV().
    
    By the way: My Delphi app runs in a window, its not a console
    application. Can I get the description of the exception with any other
    function, or how would I have to use ExceptionDescribe() in this
    context?
    
    Regards,

  - Attempting to connect to Oracle error...I was attempting to connect to an Oracle instance using the
    classes12.zip Oracle thin driver using SQuirrel 1.1final1
    [http://squirrelsql.org]. I kept receiving the following Java
    Exception:
    java.sql.SQLException: Protocol violation

    SQuirreL was successfully connecting to other Oracle instances, just
    not this particular one. I work for a large organization with
    multiple Oracle servers. Additionally, the company has just merged
    with another company. And it is the other company's server that I am
    unable to successfully connect to.
    
    After going through a number of other tangents (network issues, jdbc
    configuration details, etc.), I decided to download the classes12.zip
    file from Oracle again just in case there was some difference from the
    one I already had.
    
    Once the download completed, I checked the file dates within
    classes12.zip and their dates were all 2001/Mar/20. Then I went to
    the "old" classes12.zip I was currently using in my project and the
    file dates within were 1999/Jun/14. Surprise!!!
    
    I did a quick reconfigure of SQuirreL to use the "new" classes12.zip
    and was able to connect to the "problem" DB. Apparently there was
    some sort of update since I had last dl'ed classes12.zip from Oracle.
    
    Uh...same bloody file name, "classes12.zip", different versions. WTF?
    
    I am confused why Oracle would choose to name the zip the same name
    and not increment it when they change it. Grrr! It sure makes it
    difficult to talk about "versions" with their naming convention.
    
    And why doesn't Oracle use the industry standard .jar format and
    naming convention? Their being "rogue" makes this even more confusing
    and frustrating.
    
    Hope you find my travails useful.

  - in need of swing performance adviceHi All,
    
    I've hit a point in my app when I first call .validate() when loading a
    new panel (it is fairly complex), it takes up to 5 seconds to load..
    There must be something I can do to get over this and was wondering if
    anyone had any ideas, if you are interested then my App flows like this..
    
    A quite simple frame is initially created and displayed to user, this
    contains a button with 4 buttons, a BIG panel and a menu bar and thats
    it for now. the button bar is on left, menu at top and the Panel taking
    everything else up..
    
    When the user clicks a button, an appropriate panel is then called and
    'loaded into' the big empty space where the panel is. All this is in a
    function called Show() which is as follows...
    
    private void show(Component component) {
    java.awt.GridBagConstraints gridBagConstraints;
    gridBagConstraints = new java.awt.GridBagConstraints();
    gridBagConstraints.fill = java.awt.GridBagConstraints.BOTH;
    gridBagConstraints.anchor = java.awt.GridBagConstraints.NORTHWEST;
    gridBagConstraints.weightx = 1.0;
    gridBagConstraints.weighty = 1.0;
    
    Main.removeAll();
    Main.add(component,gridBagConstraints);
    this.validate();
    }
    
    when a button is clicked, depending on the button I call the show
    command like this...
    
    show(new divelog.forms.ProfilePanel());
    
    The panel that gets loaded that I have a problem with containt 3 panels
    in a tabpanel. each one of those has a table, and maybe 10 textfields
    per panel.
    
    So not really all that much complexity I dont think, the instantiation
    of the panel doesnt take long, so setting up the listeners I have seems
    ok its just the moment the .validate() line is executed there is the 5/6
    second delay.
    
    Anyone any ideas ? I was thinking Ok I'll create the instances of the
    panels in a seperate thread, but as I said the creation doesnt really
    take anytime at all.
    
    Thanks in advance.
