  - creating an internalFrameI'm trying to create an instance of the JInternalFrame class, which
    works fine.
    I defined a JDesktopPane named desktop and I am able to add an internal
    Frame to this JDesktopPane.
    Inside this JInternalFrame (lets call ist Frame1) I got a button which
    "should" open another JInternalFrame called Frame2 inside the same
    desktop. But it doesn't work. The compiler says it doesn't recognize the
    variable "desktop".
    How do I get him to refer to the current instance of the JDesktopPane
    I'm using? I have just one JDesktopPane as my workspace.
    thx in advance,
    Daniel

  - Transactions QuestionsI have been reading about transactions in java and have some questions:
    
    *) Which is mostly used: Container-managed transactions (CMT) or
    Bean-managed transactions (BMT)? I dont have Entity Bean in my application.
    *) Is this statement true: Use JTA only when the transaction involves more
    than 1 database else use JDBC? If yes then how would you deal with this?
    
    It would be nice if somebody points to a detailed tutorial about
    transactions.
    
    Thanks

  - File SelectorHi,
    
    How can I open the Swing-FileSelector in a special subdir?
    
    I tried it with the pathname as String, but the FileSelector starts
    always in the default dir.
    
    Thank you.

  - ResultSet and getArray()Then I have a result set named rs. I need that one column of ResultSet
    rs will be in an array.
    I've read about method getArray(), so i've thinked that my code will
    be something like that:
    ================================
    private void formWindowOpened(java.awt.event.WindowEvent evt)
    {
    ResultSet rs=mdbc.inviaQuery("select * from ... where ...");
    
    try {
    rs.next();
    txtNome.setText(rs.getString("DB_COLUMN_NAME_1"));
    rs.getArray("DB_COLUMN_NAME_2");
    } catch {
    // EXCEPTION
    }
    ================================
    Alas there's something that's go wrong and I get this error
    (paziente.java552 is the line containing
    rs.getArray("DB_COLUMN_NAME_2");) where's my mistake:

  - append string into FileHi,
    
    I am having a big trouble while saving information into a file. I would
    like append some information into file. However, each time that I try to
    do this, the information of the file is replaced by the new information.
    
    What is wrong with my routine?
    
    File simFile = new File("simulations.txt");
    //System.out.println("simulations: "+simFile.getAbsolutePath());
    try{
    if(simFile == null)
    throw new IOException();
    
    BufferedWriter output = new BufferedWriter(new FileWriter(simFile));
    
    String text = simObj.getInfo();
    output.append(text);
    //output.newLine();
    closeFile(output);
    }catch(IOException e){
    System.err.println("Cannot save Simulation into file");
    }
    
    thanks very much,

  - EasyMock, JUnit, Java5 and generics...I'm trying to create a unit test. In the unit test I need to create a
    mock java.util.List object. The List is going to be a collection of
    WebForm objects, so the way it's declared using generics as
    List<WebForm>. For my unit test I want to mock this List, but cannot
    find a way to declare the mock object in my code. The declaration is as
    follows:
    
    private MockControl<List<WebForm>> controlWebforms;
    private List<WebForm> webforms;
    
    When I try to create the mock object, the following code is invalid:
    
    controlWebforms = MockControl.createControl(List.class);
    webforms = controlWebforms.getMock();
    
    I get the error message "Type mismatch: cannot convert from
    MockControl<List> to MockControl<List<WebForm>>" However, the following
    declaration:
    
    controlWebforms = MockControl.createControl(List<WebForm>.class);
    webforms = controlWebforms.getMock();
    
    is invalid. How do I reference the class for List<WebForm> to create my
    mock object? Any ideas?

  - 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.

  - ResultSet is closedI was testing my program and the above appeared in the output. I have

    ok, just the message appeared.

java-programmer, About Sun Developer Network Subscription Hello,
I have downloaded the Sun Java Studio Creator from sun.com.
Now I am having a trial subscription of Sun Developer Network for 30
days.
But what are the advantages of it?
It seems that I can post queries about Sun Java Creator or Java Server
Faces technology only.
Can I have access to other technology documentation or it is meant for
some restricted technologies only?
PLease guide.

  - 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

  - 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!

  - 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,
    Rolf

  - Anyone have any experience with WebLogic 8?Hello, I have just installed WebLogic 814 for Solaris 8. The machine
    is in a remote location, so I did all the installation remotely. My
    question is, how do I create a data source? I am used to WL 5 with the
    weblogic.properties file, but WL 8 seems different.
    Any help is greatly apprciated, - Dave

    benchmark: fasta
    java version:
    http://shootout.alioth.debian.org/gp4/benchmark.php?test=fasta&lang=java&id=2
    C++ version
    http://shootout.alioth.debian.org/gp4/benchmark.php?test=fasta&lang=gpp&id=4
    
    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
    fasta.exe

    java 0.297s 1.347s 11.699s (-Xms64m -server)
    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.

  - Get the real type of columns from MS Access databases(OLEObject, text, memo, numeric)Hello,
    
    I made one application that opens MS Access databases.And I have one
    problem.How can I find the real data type of columns(text, memo,
    OLEObject, numeric) like it is into Access.I tried with
    resultSetMetaData.getColumnType(columnIndex) but I receive
    java.sql.Types.I have two columns that contains OLEObjects(images).But
    I receive two different types for columns : VARCHAR once, and for
    second column SMALLINT.I only want to see the types like in
    Access(OLEObjects, Text, Numeric, Memo...).Thanks in advance!

  - mailing.database.mysql-internals, mailing.database.mysql, mailing.database.mysql-java, comp.lang.java.programmerif you check the store requirements of column types in mysql,
    
    http://mysql.azc.uam.mx/doc/en/Storage_requirements.html
    
    You will see advertised that, for example, for storing a TINYINT they
    use a byte, but when you create a table using the different types of
    data:
    
    CREATE TABLE mysql_data_types (
    iTINYI TINYINT,
    iTINYINTU TINYINT UNSIGNED,
    iSMALLI SMALLINT,
    iSMALLIU SMALLINT UNSIGNED,
    iMEDIUMI MEDIUMINT,
    iMEDIUMIU MEDIUMINT UNSIGNED,
    iI INT,
    iIU INT UNSIGNED,
    lBIGINT BIGINT,
    lBIGINTU BIGINT UNSIGNED,
    fFLOAT FLOAT,
    fFLOATX24 FLOAT(24),
    fFLOATX25 FLOAT(25),
    dDOUBLE DOUBLE,
    dDOUBLEP DOUBLE PRECISION,
    dREAL REAL,
    dDECIMALM1D0 DECIMAL(1,0),
    dDECIMALM1D1 DECIMAL(1,1),
    dDECIMALM1D2 DECIMAL(1,2),
    dNUMERICM1D0 NUMERIC(1,0),
    dNUMERICM1D1 NUMERIC(1,1),
    dNUMERICM1D2 NUMERIC(1,2),
    CHARM16 CHAR(16),
    CHARM16B CHAR(16) BINARY,
    aVARCHARM255 VARCHAR(255),
    aTINYTEXT TINYTEXT,
    aTEXT TEXT,
    aMEDIUMTEXT MEDIUMTEXT,
    aLONGTEXT LONGTEXT,
    bVARCHARM255 VARCHAR(255) BINARY,
    bTINYBLOB TINYBLOB,
    bBLOB BLOB,
    bMEDIUMBLOB MEDIUMBLOB,
    bLONGBLOB LONGBLOB,
    tYEAR YEAR,
    tTIME TIME,
    tDATE DATE,
    tTIMESTAMP TIMESTAMP,
    tDATETIME DATETIME);
    
    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?

    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
