  - setCursor() for a ContentPanel
    Joana,
    
    I was having a similiar problem and did some searching and found the
    following forum:
    
    http://forum.java.sun.com/thread.jsp?forum=57&thread=110928
    
    Basically, I think you need to use setCursor on the GlassPane. I used
    the following code in my application and it seems to work.
    
    Component gp = getGlassPane();
    gp.setVisible(true);
    gp.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
    
    //do your computations
    
    gp.setCursor(Cursor.getDefaultCursor());
    gp.hide();
    
    Hope this helps,
    Kin Wong

  - Will MS be less evil now?I don't understand Gates. If he wants to do good deeds and be a
    philanthropist, why limit such good deeds to healthcare and
    education? Why not also do a good deed in the computer
    industry? In this industry he is known less for his innovations
    than for tactics such as sabotaging Java and cutting off
    Netscape's air supply. He has done the industry and consumers
    immeasurable harm, for example, by freezing the development
    of web browsers. Here's an idea for Gates: Unfreeze the web
    browser. Take web browsing to the next level. Start by
    implementing SVG, the W3 standard for vector graphics, in IE.

  - Preverifier error in Sun Java Wireless ToolkitHi ppl,
    I'm using an SDK provided by my client and building a MIDlet
    application which does ApiCalls on this SDK. I copied all the jar files
    from the SDK and put it into my lib folder of my MIDlet project so that
    it could add it to the classpath during build. But when I build it
    shows the following error:
    
    Error preverifying class com.myClient.sdk.attributes.AttributesMaster
    
    VERIFIER ERROR
    com/myClient/sdk/attributes/AttributesMaster.addErrorElements(Lorg/w3c/dom/Document;Lorg/w3c/dom/Node;[Lcom/myClient/sdk/attributes/model/ErrorSet;)Lorg/w3c/dom/Node;:
    
    Cannot find class org/w3c/dom/Node
    
    If I don't use that particular jar, and the rest of the jars, it
    shows this error:
    
    Error preverifying class com.myClient.sdk.call.AddDisputeCall
    
    java/lang/NoClassDefFoundError: com/myClient/sdk/ApiCall
    
    I read that this is because I might be using a class library created
    for the J2SE platform and hence it doesn't work for the J2ME Wireless
    toolkit which uses a limited JVM and APIs. Is there any way I can merge
    it into my MIDlet so that it will use it?
    
    P.S: I'm comparatively new to J2ME :( Also i'm using the Sun Java
    Wireless Toolkit 2.3 Beta. Please help...
    
    Thanks in advance,

  - Displaying multiple beans in a struts formI have a list of beans that I retrieved from a database. These beans
    are all of the same class. Now I want to display these beans in a
    struts form so that the user can modify the data in the beans and save
    it back to the database.
    
    Can anyone help with this problem? Is there any sample code out there
    that would show how to do this?
    
    Thanks

    I looked for your concept of "Delegation" in the only book that I have
    on UML. This is by Craig Larman. Its index does not evennnnn list it.
    
    You should expand your query to other language groups. I can do it
    for you. OOP implementation questions have been asked there before

  - Finding BeanInfo for superclass?Hi,
    
    I'm having a problem or a misunderstanding with BeanInfo.
    I have a class Alpha, and a class Beta. Beta extends Alpha. I've
    created an AlphaBeanInfo class.
    
    The following code works fine:
    
    BeanInfo info = Introspector.getBeanInfo(Alpha.class);
    ...
    
    Problem is though when I call the following code:
    
    BeanInfo info = Introspector.getBeanInfo(Beta.class);
    ...
    
    AlphaBeanInfo is not returned, nor are any of its methods called
    (verified via debugging)
    
    Shouldn't this be returned by the Introspector? I could of course write
    a BetaBeanInfo, but this seems silly to have to do this.
    
    Any ideas/clarifications?
    
    Many thanks,

  - JBOSS and IPlanet setupHi,
    
    This is a generic architectural question. I am not sure if this can
    be posted at this forum.
    
    I am using JBOSS as App server and Iplanet as WebServer and Reverse
    Proxy plugin to forward all the JSP requests from Iplanet to JBOSS.
    
    Both Web Server and App server are on different boxes.
    
    When I request a JSP page, its coming up fine. But if that JSP page
    has a 'response.sendRedirect' in it, then its failing to redirect to
    the specified page. Instead its going to the webserver root.
    
    Also, this behaviour is not consistent - meaning, sometimes it goes
    through and sometimes its coming back to webserver root.
    
    Using 'response.forward' fixed the problem.
    
    But I do not want to use 'forward' in the web application because of
    the obvious diff between 'forward' and 'redirect'. (Using the forward
    doesn't change the URL and upon browser refresh, the same form gets
    submitted again and again)
    
    Are there any alternatives to fix the redirect problem?
    
    Any help is appreciated.
    
    Thanks,

  - Reading file lines into large ListHi all,
    
    I have tried posting this problem a few times looking for a solution.
    What I have works but is slow.
    
    I have to read unordered data from a text file. Data A has a
    one-to-many relationship with Data B, and Data B has a one-to-many
    relationship with Data C . Once I find Data A, Data B and Data C could
    be anywhere in the file. So I do a RandonAccessFile.seek(0) . This
    needs to be repeated hundereds of times for lots of Data B and Data C
    relationships.
    
    I'd like to put the file in memory. However, I'm using Scanner and
    regex to get the data. I don't think I can run Scanner on ByteBuffer
    per line.
    
    So my latest idea is to read the file per line and store it in List. So
    a 10,000 line file would have a 10,000 size List. That way I could run
    Scanner on the Strings in the List, and Iterate repeatably. The data in
    the List would be read only.
    
    Any advice appreciated.

  - Labels and paint questions...I have an applet, here
    http://www.aquaticwhirlpools.com/sean/selectMenu.html
    
    What I need is for the select menus to have some space between
    them so that I can have the orange/yellow images next to each one.
    
    As you can see, there is a bit of one of the images next to
    "by product size" and a full image next to "by model".
    
    The space between the two "by product size" and "by shape" is
    created by an empty label. The image is placed in the paint method.
    
    The problem is that without the empty label, the menus have no space
    between them, as with "by shape" and "by model". Is there any other
    way to create that space... or is there a way to make the images 'paint'
    on top of the labels?
    
    Thanks for any help.

java-programmer, User privilege for getMetaData() When using a basic user with only data query and update privileges I
cannot get column data from the DatabaseMetaData object returned from
getMetaData() (on a connection using the JDBC Oracle thin driver).
When I use the schema owner with full privileges, I get the column
data. What privilege is necessary to get column information from
getMetaData?

java-programmer >> User privilege for getMetaData() I experienced the same problem with meta.getIndexInfo() (even with
approximate set to true) under Oracle, but never for meta.getColumns().
I had to do an ugly hack to work around the resulting ORA-01031
problems.

See if my SchemaSpy (http://schemaspy.sourceforge.net) experiences the
same problems.

  - Great Documentation for Investment and Trading SystemsJust wanted to let people know about a new, free Encyclopedia for Investors
    and Traders who are building or maintaining systems:
    
    Http://www.itsdoc.org
    
    "itsdoc" stands for "It's Documentation."
    
    The site attempts to provide highly accurate documentation in an
    encyclopedia format. It's 100% free, with no
    advertising whatsoever and no soliciting. The entity is entirely non-profit.
    
    Users are invited to contribute high quality material to the site and also
    draw
    from the considerable knowledge base hosted there. If you are coding
    investment
    and trading systems you will probably find this site extremely helpful.
    
    It's new, the official launch isn't until January so the site has a few
    rough
    edges right now. Still, its very useful.
    
    I hope you get a lot out of it. Please help promote it and put something
    back into it too.

  - A little optimization question: Local var allocationI often wonder: Does it make any difference in EXECUTION TIME which
    version I choose:
    
    #1:
    String st;
    while (true){
    st=dis.readLine();
    if (st==null) break;
    < do something else >
    }
    
    #2:
    while (true){
    String st=dis.readLine();
    if (st==null) break;
    < do something else >
    }
    
    It's obvious that st is valid outside the loop in #1. But does it get
    allocated on the stack for every iteration in #2, or just re-used? If
    not, I suppose #2 is preferred as far as limiting the scope, enabling
    gc, is an issue.

  - Mixed SAX and DOM processing: echoing with occassional changes.I need to write a tool which will allow me to process a huge document
    with chunks of it in memory. The procedure is to echo XML coming from
    some input to an output, then when I hit a certain type of element,
    read all of its children into a DOM and somehow manipulate it
    (specifically, the goal is to hand it to a rules engine which will add
    flags). After that is complete, serialize it right back out to the
    stream and resume processing.
    
    My approach currently involves a ContentHandler object which simply
    serializes every event using a TransformerHandler object. When I see
    the element I want, I start creating Node objects in a stack and
    assembling them into a DOM as I hit closing elements. The problem is
    that there is no direct way of serializing that DOM to the same output
    stream without violating encapsulation. At first I thought that I
    would be able to pass the DOM to a SAX ContentHandler (which I would
    provide with a reference to the TransformerHandler doing the
    serialization). However, it turns out that isn't the case. I do not
    want to reinvent the wheel and walk the DOM manually nor do I want to
    create (potential) side-effects by writing directly to the OutputStream
    wrapped by my Result object using XMLSerializer on the DOM. XMLFilters
    do not appear to be a solution because I cannot apply my rules in a
    streamable fashion (and getting a DOM from the incoming stream is not
    the difficult part anyway).
    
    I've looked around and found a variety of mixed parsing techniques, but
    it seems that none of them quite meet my needs. Writing a class which
    takes a DOM, walks it, then calls the appropriate ContentHandler
    methods would not be too painful, but this seems horribly inelegant to
    me. Also, I cannot even begin to fathom that I am the only person who
    wants to do this.
    
    Any suggestions?
    
    (What follows is some code which may give an idea of where I am at.
    Simplified for brevity.)

    The message for sending the receiving is in XML format.
    
    Could any one help me following in questions.
    
    1> Since there is 30 request at time so for improve the performance
    and resources I need to do connection pooling.
    How can I achieve this using base classes.
    2> While retrieving (getting) the message for particular request how
    can I identify the response message.
    i.e. when client#1 request data from queue he must get data related
    to client#1 only not other than client#1.
    because In above scenario there are separate queues for getting the
    message and putting the message.
    
    I have read the tutorial on connection pulling but I am little
    confused.

  - jxta in subnetHallo,
    
    i have a broblem with the jxta technology. I build up a testbed
    consisting of a server a router and two clients. The router is
    connected to the two clients and the server. Any connection from one
    client to another or from one client to the server goes through the
    router. Client 1 is configured with ip 192.168.100.1, client two with
    172.16.0.1 and the server with 10.0.0.2. So the router routes for
    three different subnets. No machine has access to the another (except
    the router). There is also no connection to the internet.I wrote an
    application built on jxta. The application runs on the server and the
    two clients. I configured the peers as rendevouzs and added to every
    peer the ip's of the two others to the list of known rendevouzs peers.
    When i run my application, the peers can find each other, BUT it needs
    a lot of time, somtimes about 10 miutes. I cannot understand this,
    because the peers know each other by the list of known rendevouzs. How
    can i improve the time the peers need to find each other? I think my
    configuration settup is ok (, otherwise the peers never would find
    each other?).
    Can anyone help me ?

  - JTextArea append method doesn't always appendI have an application with many custom loggers, and a number of JTextArea
    instances for displaying the log entries written to the loggers. Each
    JTextArea has a thread associated with it that continuously pulls entries
    out of a particular logger and appends that text to the JTextArea. Thus,
    each entry written to a logger should show up in the associated JTextArea.
    
    The problem I have is that not all the log entries show up in the text area,
    and what shows up and what does not can change with each execution. I've
    put print statements before and after the log statements, and before and
    after the text area append, and all the expected log entries show up at all
    those places. Only in the JTextArea is there variability in what shows up.
    Is this a bug in JTextArea, or is this some known behavior?

  - Automated Basic Authenication with an Applet for the Browser ?I like to automate web access to secure pages and proxies, which are
    proteced with a Basic Authenication scheme.
    
    The Basic Authentication within an Applet works really well, I get all
    the information I need when I attach the
    
    Authorization: Basic base64encodeUID_PW to the request Header.
    or
    if I use the Authenticator Class of the JDK1.5.
    
    My problem is that the browser does not notice that I already have
    a UID/Password combination for the desired web page.
    
    When I did the same with a form based authorisation the URLConnection
    was setting the Cookie inside the browser implicitly, the
    showDocument() method displayed the secure page, because the browser
    used the cookie to access it.
    
    Is there any way to access the cache for the UID and Password of the
    browser to set these values that when I invoke the showDocument() to
    display the page inside the browser, I don't have to enter the UID and
    Password again?
    
    My current code to authenticate myself is this, I also tried a direct
    socket connection and a HttpURLConnection there was no difference:
    
    String urlString =
    "http://www.demo.com/basicprotectedpage/index.html"
    AppletContext appCont = getAppletContext();
    
    //created password authenticator.
    mmAuthenticator myPassAuth = new mmAuthenticator(uid,pw);
    //setting password.
    Authenticator.setDefault(myPassAuth);
    
    //URL created.
    URL url = new URL(urlString);
    //opening connection
    URLConnection conn = url.openConnection();
    
    //setting do input and do output.
    conn.setDoInput(true);
    conn.setDoOutput(true);
    conn.setUseCaches(true);
    
    //Data Input Stream
    
    BufferedReader bin = new BufferedReader(new
    InputStreamReader(conn.getInputStream()));
    String inputLine;
    System.out.println("web page data " );
    while ((inputLine = bin.readLine()) != null)
    
    System.out.println(inputLine);
    
    bin.close();
    
    appCont.showDocument(new URL(urlString)); // this should
    display the secure page without the prompt for uid password
    
    Thank you in advance. Have a nice day.

  - Crystal Report Change Data SourceI have a few crystal reports (XI) that uses JDBC to connect to MS SQL
    Server. The JDBC Driver is JTDS 1.1. Now I am trying to update the data
    source definition to include JNDI name so it can be more portable. The
    trouble is I can't update it.
    
    Here's what I've tried on existing working reports:
    
    - Go to "Set Datasource Location" dialog, expand current data source
    properties, add JNDI connection name. Crystal now pops up a dialog box,
    asking me to confirm connection info. So I put in user ID and Password.
    Clicking "Finish" and Crystal pops up a message saying "Logon failed.
    Details: SQL Exception: [SQL State:] 08501 [Error Message:] Network
    error IOException: Connection refused: connect". Then the same
    connection fonfirmation dialog come up again as if i typed in wrong
    user name and password.
    
    - The next thing I tried (since I can't manually add JNDI name) is to
    replace existing datasource with another one. Again, I go to "Set
    Datasource Location". I've already defined another JDBC connection with
    JNDI name in it. now selecting existing connection in the tree at the
    top and select the new connection in the tree at the bottom, click
    "Update". Now connection confirmation dialog pops up. After entering
    user id and password, I click Finish. Then Crystal says
    - "Data Object cannot be opened/accessed."
    - "Database Connector Error: 'Unexpected error'"
    - "Data Object cannot be opened/accessed."
    - "Database Connector Error: 'Unexpected error'"
    - "Some tables could not be replaced, as no match was found in the
    new data source. Please specify the table required for any unmodified
    tables."
    
    Some more information regarding existing reports. When I created the
    reports, Crystal complains about not able to find the tables and offer
    me to remove the related fields from the report. I clicked "No" and the
    reports still runs perfectly fine.
    
    There isn't much I can do after this. So I look up on the web, I think
    it may have to do with the not so well implemented "verify database"
    functionality, but I have no way to prove or solve it.
    
    Can anyone help me on this? The database is the same, so theoretically
    there shouldn't be any problem updating the datasource defintion,
    especially when the datasource is the same as before. And adding JNDI
    name to the report shouldn't be a problem either because it won't get
    use until a Java app try to run it.
    
    Any suggestions?
    
    Thanks,
    Jo

    It's easily fixable, should you be so inclined. What's wrong with it
    though - it's what I've read in the past, that MacOS X is the Mach
    microkernel (tightly) wed to bits and pieces of a BSD (I'm not sure
    which, I think FreeBSD or NetBSD).
