  - How to get address of a Java object?Hi
    
    Is there a way to get address of a Java object?
    I believe hashCode function in Object class do gives the object
    reference, but this is specific to JVM implementation.
    
    thanks,

  - Maven / Torque Generator ClasspathHello,
    
    I try to make an XML dump of a oracle database schema with the Torque
    Generator jakarta api.
    
    But, I cannot find how use Torque Generator without Maven and I connot find
    how to put the "classes12.jar" oracle JDBC Driver in the Maven classpath.
    
    So, I get the following exception :

  - JavaMail: MimeMessage customer headersHow to add custom headers to a MimeMessage object?
    The problem I'am having is reading from POP3 account and getting the
    MimeMessage object. Before I want to save the message content to disk,
    I want to add a few headers.
    
    The error I'am getting is
    POP3 messages are read-only
    
    I've open the inbox folder as READ_WRITE but still no luck.
    Anyone know how to add customer headers to the MimeMessage object when
    reading from a POP3 account?

    The WCECS 2008 is organized by the International Association of
    Engineers (IAENG), a non-profit international association for the
    engineers and the computer scientists. The congress has the focus on
    the frontier topics in the theoretical and applied engineering and
    computer science subjects. The WCECS conferences serve as good
    platforms for our members and the entire engineering community to meet
    with each other and to exchange ideas. Our last IAENG conference has
    attracted more than one thousand participants from over 30 countries,
    and our conference committees have been formed with over two hundred
    and sixty committee members who are mainly research center heads,
    faculty deans, department heads, professors, and research scientists
    from over 20 countries.
    
    All submitted papers will be under peer review and accepted papers
    will be published in the conference proceeding (ISBN:
    978-988-98671-0-2). The abstracts will be indexed and available at
    major academic databases. The accepted papers will also be considered
    for publication in the special issues of the journal Engineering
    Letters, in IAENG journals and in edited books. Revised and expanded
    version of the selected papers may also be included as book chapters
    in the standalone edited books under the framework of cooperation
    between IAENG and Springer, and between IAENG and America Institute of
    Physics. For reference, the following post conference edited books of
    our recent IAENG 2007 conferences have been scheduled to be published
    by Springer in early 2008: Trends in Intelligent Systems and Computer
    Engineering, Advances in Communication Systems and Electrical

    As a great example of c++ portability, this doesn't even compile with
    my version of g++ (mingw), so I will use cygwin to compile. gcc
    version 3.4.4 (cygming special)
    
    g++ -pipe -O3 -fomit-frame-pointer -mfpmath=sse -msse2 fasta.cpp -o

    jet 0.420s 1.701s 14.602s
    
    (note this guy uses -Xbatch flag everywhere. I have to see how that
    helps anywhere. It's just slightly slower with -Xbatch flag if
    anything).
    
    HotSpot VM is faster than native Jet compiler once again? That's three
    in a row. g++ is only slightly faster, not 50 or 100 times as some
    think.

  - Corrupt String or bytearray transport over RMIHello,
    
    I have a strange problem when transporting a String and it's byteArray
    between 2 JVM's on the same machine. The JVMs are seperately started
    instances of IBM's 1.3.1 JVM which also comes with Websphere 4.5.
    
    On JVM1, I have something along the lines of:
    
    String jvm1String = "Some nice String";
    byte[] jvm1bytes = jvm1String.getBytes("ISO-8859-1");
    
    Now, I transport the string and the array through RMI toto JVM2. In
    JVM2 I do the following:
    
    jvm2bytes = jvm1String.getBytes("ISO-8859-1");
    
    for (int i = 0; i < jvm2bytes.length; i++) {
    if (jvm2bytes[i] != jvm1bytes[i]) return false;
    }
    
    This allways returns false. Manually checking the arrays shows that the
    two byte arrays only differ somewhere in the middle, and only for about
    2 bytes, regardless the content of the String. I have no idea what
    would cause java to behave differently between the two jvm's.
    
    My question is: Is this likely to be a bug in:
    a) the transportation of Strings over RMI
    b) the transportation of byte arrays over RMI
    c) the way String.getBytes("ISO-8859-1") is implemented
    d) the way I am using rmi or the getBytes() method
    
    Due to requirements, I can not change the JVM, so I need to find a way
    around this. I am using the bytearrays to verify data integrity.
    
    Thanks in advance,

  - ANN: VRMLmagic - New Interactive 3D VRML Web/World Authoring ToolHi All,
    
    We at Scintillating Graphics would like to announce the release of
    VRMLmagic, our Interactive 3D Web Development Tool.
    
    VRMLmagic is an easy to use tool for creating interactive 3D (Virtual
    Reality) web pages in the VRML/X3D format(s). With its interactive 3D
    development environment and a range of powerful tools, you'll find
    yourself building interactive 3D worlds in no time. Take a look at our
    web site for more info:
    
    http://www.scintillatinggraphics.com.au/VRMLmagic/
    
    Initially developed as part of a research project with the aim of
    making a rapid development environment for the construction of 3D user
    interfaces. It was clear that VRMLmagic's features (which enabled us
    to quickly build interactive 3D interfaces) had enormous potential for
    the mainstream web development industry, and in particular its ability
    to bring 3D content to the web. We now hope this tool will enable you
    to begin developing the potential of interactive 3D content for the
    web.
    
    The initial release is for the Windows (98 and above) platforms.
    However we will soon be releasing versions for Mac OS X and other Unix
    variants.
    
    If you have any questions or would like additional information, email
    us at email***@***.com

  - Jar file exploringHi,
    I want to read files and direcotories under a specific directory in a jar
    file. In this way I can explore
    the jar file interactively. The jar file contains thousands of files and has
    no index.
    So it is impractical to enumerate entries then filter them.
    How can I do this? Thanks.

  - How to re-asign a value to a variable in XSLTSorry Dudes,
    
    I couldn't find an appropriate group to post about XML/XSLT issues.
    I can only post to these close groups.
    
    In most of programming languages are VERY easy to do:
    
    int i = 0;
    i = 3;
    i = i + 1;
    i += 2;
    i++;
    
    But how can I do these in XSLT?
    
    I got error when I do
    <xsl:variable name="i" select='0' />
    <xsl:variable name="i" select="$i + '1' />
    
    Can dudes (American West Coast's Term) out there can help?
    
    Thank Q!

    However when you use JDBC to query the column definitions, see:
    
    http://java.sun.com/j2se/1.4.2/docs/api/java/sql/DatabaseMetaData.html#getColumns
    
    with code like:
    
    Cx = DriverManager.getConnection(aJDBCP + aTblDB, aUsr, aPW);
    DBMD = Cx.getMetaData();
    // __
    RSFlds = DBMD.getColumns(aTblDB, null, aTblNm, "%");
    // __
    while(RSFlds.next()){
    ++itFldIx;
    aFldNm = RSFlds.getString(4);
    // __
    iFTp = RSFlds.getInt(5); // java.sql.Types
    aFTpS = RSFlds.getString(6); // TYPE_NAME
    iFSz = RSFlds.getInt(7); // COLUMN_SIZE
    iDecDigs = RSFlds.getInt(9);
    iFNull = RSFlds.getInt(11);
    iOrdPos = RSFlds.getInt(17);
    ...
    }
    // __
    
    You will for example see that for a tinyint 4 bytes are being used
    and that the column type in string format, does not return the
    'unsigned' type specifier. Also, apparenly MySQL uses one byte less
    for 'unsigned' variables.
    
    Which is a little fishy to me. Both 'signed' and 'unsigned' variables
    should use the same storage they are just interpreted differently,
    since just one bit is used for the sign.
    
    MySQL returns the same DATA_TYPE in the form of an java.sql.Types int
    and TYPE_NAME as a String for 'signed' and 'unsigned' variables
    
    Trying to use the difference in the COLUMN_SIZE specifier does not
    work for example for 'BIGINT' and 'BIGINT UNSIGNED'.
    
    How can you tell from the Data Type Definition/specifiers which
    fields are unsigned ones?
    
    There should be a 'descriptive' way right? (Other than going the
    monkey way, inserting some data, retrieving it, comparing it and
    deleting the test record, with which, well . . ., should be definitely
    safe)
    
    Do you know of standard or none standard ways to do that?

    Fair enough, let's consider as a warm up for the discussion that will come
    once you'll show your proposal ;-)

  - changing Reader midstreami have what seems to be a fairly common problem, but i can't seem to find an
    answer... i have a java program which opens a connection to a webpage and
    seeks to read the webpage in. if the charset is defined in the header, then
    no problem - i simply set up my InputStreamReader using the correct Charset
    and away i go. but if the charset is defined in a META tag, then i want to
    be able to recognize that.
    
    a good example of why this is important: Yahoo! Japan uses EUC-JP encoding,
    and specifies it in the header. Excite Japan uses Shift_JIS encoding, and
    specifies it in the META tag.
    
    here's some pseudocode:
    
    URL url = new URL(webpage);
    URLConnection conn = url.openConnection();
    if (conn.contentType() != null)
    charset = getCharset(conn.contentType()); // yay!
    else
    charset = ISO-8859-1; // default
    
    InputStream = conn.getInputStream();
    BufferedReader reader = new BufferedReader(new
    InputStreamReader(in,charset));
    while (get data from reader) {
    if (data is META tag && content-type specifies a new charset) {
    reader = new BufferedReader(new InputStreamReader(in,newCharset));
    // this is the problem
    }
    }
    
    this, unfortunately, does not seem to work. is there a better (i.e.,
    standard) way to do this?
    
    thanks!

  - Add ActionListener to an Action
    Okay so Action is fine for centralising event handling for multiple controls
    of the same function. But I want to add a plain ActionListener for this
    event. Seems reasonable. If I was just using ActionListeners I would add
    as many as I like to a component. And they'd all be notified, but if I use
    Action then I need to add the ActionListener to the Action, I can't.
    Do I really need to get my subclassed AbstractAction to manage
    ActionListeners and propagate the ActionEvent by calling
    super.actionPerformed ?
    Is there a better way? Other than abusing PropertyChangeListener ?

  - getting hostname from NT machine via CitrixHi All,
    
    I don't know if any one can help or has any ideas about this.
    
    We are writing a web based application which will run on a Unix box. It will
    be accessible only via a login to Citrix from client machines. We have
    achieved a transparent login to the application (running in Tomcat) using an
    LDAP lookup. What we are stuck on is the following. We would like to be able
    to get the hostname of the NT machine which is logging on. Someone has
    suggested that we may be able to do this using a signed applet. I have no
    experience with Applets at all & wondered if any one knows if this is
    achievable or has accomplished anything similar? Any other ideas on how we
    might do this?
    
    Many thanks

  - Final field & custom serialized formatI have a class which has a single field:
    
    private final File nameFile;
    
    When serializing it, I want to save it as a String, rather than a File.
    This will allow me to better check for platform incompatibilities during
    deserialization.
    
    I can serialize it like so:
    
    private transient final File nameFile;
    
    private void writeObject(ObjectOutputStream out) throws IOException
    {
    out.defaultWriteObject();
    out.writeObject(nameFile.getPath());
    }
    
    A straightforward approach to deserialization won't work, however, for
    the obvious reason that I won't be able to set nameFile to the File I
    construct from my deserialized String.
    
    I can't be the first person to run into this. What have others done in
    this situation?
    
    Thanks!

  - launch java(swing) applications from c/c++ on mac os xI want to launch a java application, which has lots of swing stuff in
    it, as also underlying algorithms running. I work on Mac OS X 10.3.8,
    and have Java 1.4.2_05(latest). I tried to launch AWT components like
    Frame,Panel, etc and it worked fine, but swing won't. I discovered that
    the code by default loads Java 1.3.1, and JNI 1.2, and hence no swing
    is supported. Can someone help me out? Thanks in advance. Here is a

  - Servlet as JMS Sender/Receiver ?
    Can a Servlet act as both a JMS Message Sender and Receiver?
    
    Clients who call on this servlet would be BLOCKING for a response.
    The servlet itself upon receival of client request sends the message to
    the request MQ queue. This message will be picked up by a standalone
    app(JMS client), after processing would write to the response queue.
    Meanwhile the servlet would be polling onto the response JMS queue with
    receive(timeOutPeriod) with the appropriate msg-selector.
    
    Is there any other approach to avoid the blocking receive. I have read
    that server side polling would use lot of sys resources and block the
    threads. What other feasible approach is possible?
    
    Having an asynch imple. is a NO in this case because clients cannot
    write messages to the Queue.
    
    The appln is hosted on WebSphere5 ND.
    
    Any feedback would be very helpful. Thanks.

  - java code compressioni'm writing an applet which is growing a little out of control, and i'm
    trying to cut down on the size of the final applet without reducing
    functionality. is there a way to strip all excess symbols out of the applet
    at compile time, or munge the internal names so that they're shorter?
    coming from a C++ background, i have all of these nice, long explanatory
    names for my constants - which end up taking an absurd amount of space.
    
    any help would be appreciated!

    In following my hearts calling it leads me to tell you to say
    welcome
    I see some-thing that i guess allot of people do not see.
    And that is a blessing from the storm.
    Let me tell you a little bit about me self if i may.
    You see all i have i gave up to GOD to this vary day.
    For all i had is now in GOD'S hands i have nothing left but HIM.
    No Car , ID , Income , House ,Wife Every-Thing is gone.
    Plus i have never been happier living in faith totally.
    >as i make my bed in SHEOL thou art with me .
    
    For in Not knowing what i will be doing up until the time i do it
    gives GOD all the time HE needs to work through me.
    And in doing so giving HIM all the GLORY found in it as well.
    The truth found in a Ethereal world we all live in
    And my faith in him is growing faster and faster on a daily bases.
    For HE is giving me guidance from my prayers through is SON.
    To show you ; and the world.
    That with out doughy HE is real.
    And have that doughty cast into the Ocean for good.
    Just like you see that HELL washed away.
    Right from the boat you see me on in this site in-which i gave back
    to
    HIM
    HIM who GOD.
    Are Father in Heaven who it be thy name.
    So to get back to what i mean ; in i see something that i feel allot
    of you don't see.
    and that being the blessing found in the wood laying all a muck down
    south in the Gulf Coast of are Country. For Behold it is overlaid
    with
    Gold and silver.
    Look in the Bible to see some answers to just what can happen when
    you
    wait on HIM for the answer
    A CKICK Away
    http://www.biblegateway.com/passage/?search=Habakkuk%202:19,20%20;&ve...
    " Behold, it is overlaid with gold and silver,
    Yet in it there is no breath at all.
    20 " But the LORD is in His holy temple.
    Let all the earth keep silence before Him."
    
    What we do is simple we pick up all the little pieces that are laying
    every were. And stock pile it for Manufacture.
    say at all the Libraries to start. And just a shoe box full.
    For then theo's well off or well to do people who wish to give Money
    to these Paper-weight-pen-holders.
    Ones lets say that are made just for these Donates in the Gluf Coast
    and New Orleans area in-which were they were made our collected
    at.People then who pay for them with this program could go through
    its
    fruition creating something of value big time for its monetary Value.
    Plus everyone who helped from the people how picked it up to the
    driver who drove it plus the plant.
    Who made particle board out of it.
    And with the scraps left over sent it then to have it then in-cased
    in plex-glass and made into that paper weight pen holder thanking the
    Donation given from that person who bought it and in faith allow
    blessing to come from it when being seen to all who see it on there
    desk.
    Plus they then can write there vision like i wrote mine.
    
    >From this blessing found in the storm and are Country's biggest
    
    natural disaster.
    Thank you GOD for this vision
    In " Jesus the Christ "
    Name ipray.

    I see some-thing that i guess allot of people do not see.
    And that is a blessing from the storm.
    Let me tell you a little bit about me self if i may.
    You see all i have i gave up to GOD to this vary day.
    For all i had is now in GOD'S hands i have nothing left but HIM.
    No Car , ID , Income , House ,Wife Every-Thing is gone.
    Plus i have never been happier living in faith totally.
    >as i make my bed in SHEOL thou art with me .
    
    For in Not knowing what i will be doing up until the time i do it
    gives GOD all the time HE needs to work through me.
    And in doing so giving HIM all the GLORY found in it as well.
    The truth found in a Ethereal world we all live in
    And my faith in him is growing faster and faster on a daily bases.
    For HE is giving me guidance from my prayers through is SON.
    To show you ; and the world.
    That with out doughy HE is real.
    And have that doughty cast into the Ocean for good.
    Just like you see that HELL washed away.
    Right from the boat you see me on in this site in-which i gave back
    to
    HIM
    HIM who GOD.
    Are Father in Heaven who it be thy name.
    So to get back to what i mean ; in i see something that i feel allot
    of you don't see.
    and that being the blessing found in the wood laying all a muck down
    south in the Gulf Coast of are Country. For Behold it is overlaid
    with
    Gold and silver.
    Look in the Bible to see some answers to just what can happen when
    you
    wait on HIM for the answer
    A CKICK Away
    http://www.biblegateway.com/passage/?search=Habakkuk%202:19,20%20;&ve...
    " Behold, it is overlaid with gold and silver,
    Yet in it there is no breath at all.
    20 " But the LORD is in His holy temple.
    Let all the earth keep silence before Him."
    
    What we do is simple we pick up all the little pieces that are laying
    every were. And stock pile it for Manufacture.
    say at all the Libraries to start. And just a shoe box full.
    For then theo's well off or well to do people who wish to give Money
    to these Paper-weight-pen-holders.
    Ones lets say that are made just for these Donates in the Gluf Coast
    and New Orleans area in-which were they were made our collected
    at.People then who pay for them with this program could go through
    its
    fruition creating something of value big time for its monetary Value.
    Plus everyone who helped from the people how picked it up to the
    driver who drove it plus the plant.
    Who made particle board out of it.
    And with the scraps left over sent it then to have it then in-cased
    in plex-glass and made into that paper weight pen holder thanking the
    Donation given from that person who bought it and in faith allow
    blessing to come from it when being seen to all who see it on there
    desk.
    Plus they then can write there vision like i wrote mine.
    
    >From this blessing found in the storm and are Country's biggest
    
    natural disaster.
    Thank you GOD for this vision
    In " Jesus the Christ "
    Name ipray.

  - generate private key from a exist fileHi
    
    i want to generate a private key from a exist file. i tried this but it
    dosen't works!
    
    ---------Code--------------
    
    FileInputStream keyfis = new FileInputStream("keyCarlaSchaffner.pem");
    //"keyCarlaSchaffner.der"
    byte[] encKey = new byte[keyfis.available()];
    keyfis.read(encKey);
    keyfis.close();
    
    X509EncodedKeySpec privKeySpec = new X509EncodedKeySpec(encKey);
    
    KeyFactory kf = KeyFactory.getInstance("RSA");
    PrivateKey pk = kf.generatePrivate(privKeySpec);
    
    ---------Code end ----------
    
    i have the private key file in pem and der encoded version, but both didn't
    work.
    
    PEM :
    
    -----BEGIN RSA PRIVATE KEY-----
    Proc-Type: 4,ENCRYPTED
    DEK-Info: DES-EDE3-CBC,F836EA29BA0C7925
    
    ....
    ...
    ...
    -----END RSA PRIVATE KEY-----
    
    DER: no readable
    
    the exception is:
    --------------------------------
    
    java.security.spec.InvalidKeySpecException: Key spec not RSA.

  - Per-Session Cookies and Java ProgramsHello. I'm currently writing a java program that connects to a website
    and reads information from it. Eventually it will return a URL for the
    user to go to. The only problem is there are a lot of "per-session"
    temporary cookies involved. I haven't found a way to go from the java
    program's URL to the URL in IE because of all of the per-session
    cookies involved. Does anyone have any idea how I can save the
    per-session cookies from java into IE or a way around this? My last
    hope is just opening the webpage in the java gui.

  - DAO - best practicesHi All,
    
    I know this is a little bit OT
    
    Suppose I have 2 tables customers and products, customer can buy many
    products, product can be bought by many customers - typical n:m
    relationship so 3rd table is a must: i.e. purchases
    
    So I need 3 DAO: ProductDAO, CustomerDAO and PurchaseDAO.
    
    How do you deal with i.e. reports - table joins, left joins or
    statistics (group by, max, min etc)?
    
    do you create DAOs for that? (especially table joins - probably not)
    
    raports and statistics from i.e. 7 tables can be only read-only, so
    insert, update, delete methods
    are inadequate.
    
    thanks in advance for shedding some light on this
    best regards

  - JTable size adjustment after addrow(), JScrollPaneHi all.
    
    Basically I'm doing the following:
    
    --snip--
    DefaultTableModel myTableModel=
    new DefaultTableModel(new String[] {"header1","header2"},0);
    JTable myTable=new JTable();
    myTable.setModel(myTableModel);
    
    TableScrollPane.setViewportView(myTable);
    --snap--
    
    When I do some myTable.addrow(...)s, the table is not resizing istself
    appropriately, resulting in data being "cut off" at the bottom.
    
    Does anyone know how to correctly adjust a table's preferred size (or
    whatever) after changing its contents to fit the new row count and thus
    making it usable in a ScrollPane?
    
    Many thanks in advance,
    
    Maximilian
