  - PrintServiceLookup.lookupPrintServices fails to list new printers until re-start (JDK1.4.2_03, Linux RedHat, Tomcat 4.x)Hi Forum,
    How could I get
    javax.print.PrintServiceLookup.lookupPrintServices(null,null) to return the
    current available services while the program that uses lookupPrintServices
    is running? In a tomcat servlet I use the lookupPrintServices(..) to get a
    list of the printer services available. The class works well and returns the
    list but if I install a new printer, the servlet does not list the newly
    installed service until I restart Tomcat. Is there a way to unload and
    reload the PrintServiceLookup class and then call
    PrintServiceLookup.lookupPrintServices?
    
    It appears that the lookupPrintServices(..) returns the list of services
    that was available when the instance of the virtual machine was started.
    Hence, while the instance is running, it allways returns the same list of
    services. If I run a program that lists the services and then exits, the
    program lists the newly added printer on re-run. But if the program never
    exits (it runs in a loop, re-listing the services every so often), and I add
    a new printer while the program is running, the newly added printer is not
    listed until I terminate teh rpogram and re-start it.
    
    Thanks in advance for your responser

  - what i do wrong???Hello All!
    
    I think I have a mistake in my logical sequence of thoughts...
    
    When I want to take influence on my JComponents (JTextField,
    JCheckBox, etc.),
    do I have to place a listener within the constructor???
    
    My problem was the following. I wanted to get the values from my
    different JTextFields an write them to any *.txt file. That did only
    work, when I inserted a KeyListener who registered any changes in the
    text fields. But my real problem is now, to get the values back from
    the *.txt file an set them with setText(String) in the text fields.
    This don't work.
    I have seen in the NG, that there will be oft spoken about
    revalidate() or repaint(), but that don't work anyway.
    It does not matter, what I want to do - set a component enabled, or
    disabled or what ever, I have to have an adequate listener within the
    constructor so that the changes will be visible, isn't it that way???
    For example:
    
    public void any_method()
    {
    myTextfield.setEnabled(false);
    }
    // IT DON'T WORK
    // ...but I don't know why. When I put it within the constructor, it
    works...
    
    I don't know what to to. I know it from MFC, there I could get
    influence on my components in any method.
    
    I don't know what I do wrong in Java.
    (My program is an application with JFrame and SWING componets. I use
    JTabbedPane and for each tab a Jpanel)
    
    There must be a simple solution for my problem (I hope so).
    Please led me out from this dead-end street.
    
    Thanks in advance

  - performance and memory usage.
    Hi
    
    I created a test program to try the speed and size management of the JDK
    HashMap. With regards to this I was wondering if anybody has any
    comments on whether this is an appropriate way of testing this
    performance, i.e. how realistic is the results with respect to caching
    influence of data, heap management etc. The code is simple, but would it
    produce a correct result. (the program finishes in 11 seconds on my
    machine). the code is attached.
    
    Secondly, I was wondering about the memory (heap) usage in java for this
    program. It needs at least 256 MB of heap to run to finish. cmd:
    
    java -Xms32m -Xmx256m -cp target/classes/ App
    
    Using -Xmx128m causes OutOfMemoryError.
    
    When calculating on the size of the datastructure i find approx that
    
    2M Dto's = 16MB
    2M Integer's for map key = 8MB
    2M Integer's for ArrayList = 8MB
    
    Thats a total of 32MB plus some megabytes for the objects,
    datastructures, JVM and so on. So probably about 48-64MB in total.
    Thats a completely different number from 128 MB or 256 MB.
    
    Does anybody have any comments on why the program requires that much memory?

    I have interesting problem with javax.swing.JComboBox (java 1.4.2)
    
    When I click at combo to open list - there is no reaction to mouse

  - Precision problem with doubleHi everyone,
    
    I am a Java beginner, and I am trying to create a very simple binary
    tree.
    Each node has a value, the left child has the same value + an
    increment, the right child has the same value - the same increment.
    I try to recursively create the tree, but I have precision problems.
    
    My "main" node has a value of 10, the increment is 0.1, tree depth is
    4
    So i want a tree that goes like this :
    depth 1 : 10
    depth 2 : 0.9 / 10.1
    depth 3 : 0.8 / 10 / 10 / 10.2
    depth 4 : 0.7 / 0.9 / 0.9 / 10.1 / 0.9 / 10.1 / 10.1 / 10.3
    
    But at depth 4 when I try to print the value I get 9.700000000000001
    instead of 9.7, and 10.299999999999999 instead of 10.3
    And things get worse when the depth increase.
    All the values and increment are stored in double (native type).
    
    Is it normal? How can I avoid this problem?
    Thanks a lot,
    Tom.
    
    [main class]
    double increment = 0.1;
    double startValue = 10;
    int maxDepth = 4;
    Tree myTree = new Tree(startValue, 1);
    myTree.recursivelyCreateChildren(increment, maxDepth);
    
    [Tree.java]
    public int depth;
    public double value;
    public Tree leftChild;
    public Tree rightChild;
    
    Tree(double value, int depth){
    this.value=value;
    this.depth=depth;
    System.out.println("node of depth " + depth + " created, value = " +
    value);
    }
    
    public void createChildren(double increment){
    rightChild = new Tree(value - increment, depth+1);
    leftChild = new Tree(value + increment, depth+1);
    }
    
    public void recursivelyCreateChildren(double increment, int maxDepth)
    {
    if (depth < maxDepth){
    createChildren(increment);
    leftChild.recursivelyCreateChildren(increment, maxDepth);
    rightChild.recursivelyCreateChildren(increment, maxDepth);
    }

  - show a form from anotherPlease bear with me as I am pretty new to Java.
    I am developing a Java Client application.
    I have a frame with a button. When I click on the button, it hides the
    current frame and opens another frame which is in another class.
    When I click on a button on this second frame, I want to close it
    (this.dispose) and show the first frame.
    The question I have is:
    From the second class frame, how do I reference the first frame?
    I don't want to close the first frame as I want to keep any data entered.

  - Reference and Garbage CollectionI'm not quite sure about what kind of references to an object determine
    its "alive" quality and its readiness for garbage collection. For the
    moment I understand that *any* living reference, including non-explict
    of member classes, keep the object alive.
    
    Would you agree that the follwoing class "NeverRelease" entails
    instances which will never get prone to garbage collection?
    
    class NeverRelease
    {
    Child1 child;
    
    public NeverRelease ()
    {
    child = new Child1();
    }
    
    private class Child1
    {
    }
    }
    
    While would you also agree that instances of the following class
    "AlwaysRelease" always become garbage because the member class is static
    and hence does not take reference to the enclosing class?
    
    class AlwaysRelease
    {
    Child2 child;
    
    public AlwaysRelease ()
    {
    child = new Child2();
    }
    
    private static class Child2
    {
    }
    }

    I can't believe that projects like Eclipse are doing so well, simply because

java-programmer, Hibernate and Eclipse -- where to start? Hi folks,

This began as a thread in comp.lang.java.programmer, but the focus has
really moved toward db stuff, so I repost bits here. For the full
thread, see "searching for yoda - a developer's tale" at:

http://groups-beta.google.com/group/comp.lang.java.programmer/browse_frm/thread/aa12c688b702cc72/f769b8aebe720db5?_done=%2Fgroup%2Fcomp.lang.java.programmer%2Fthreads%3Fstart%3D0%26order%3Drecent%26&_doneTitle=Back&&d#f769b8aebe720db5

[...] how to fit Hibernate into Eclipse. Again, my problem statement
is that I naturally work with objects and object graphs and would
prefer to spend most of my development effort in this domain. I would
like as much as possible to have mapping and schema handled by the
tool. It *seems* to me that the "natural" mode for Hibernate is to
start with the mapping and use the tools to generate Java and schema.
This is still better than starting with a relational model.

The learning required for these technologies is what I'm confused
about. What exactly do I need to learn? I have a couple of Hibernate
books (the "in Action" is one of them and is, so far, quite good). The
API seems reasonable and not too intimidating. If I were still a
vi/JDBC coder, I would simply add Hibernate API as a tool and
incrementally move forward. But, now that I'm a full-fledged Eclipse
user and committed to focusing on the object model, I'd like to (1)
integrate Hibernate into Eclipse (via any of the afore-mentioned
plug-ins or others), and (2) try to work from the object side of ORM.

Online docs for the plug-ins to solve (1) seem weak. It's hard to tell
which plug-in does what, and what the advantages/disadvantages of each
might be. (2) seems to imply, from my reading, a need for XDoclet or
some other Attribute-Oriented solution to bury the necessary hibernate
tags into the code. Once again, the docs I've found seem weak. More to
the point, as I've mentioned, each new link leads to five others and
their associated technology requirements...It just gets out of hand
quickly. My hope is for someone here to point the way through the fog
and say "here's how to integrate Hibernate" or perhaps "don't bother
integrating Hibernate, use this basic config file and modify as
needed", etc.

Any guidance would be greatly appreciated.

  - Logging APIHello,
    
    I have been using the logging API to log HTTP requests. I have an
    object, which resembles a HTTP request and has methods to extract the
    typical fields of a HTTP request.
    
    Now, I have noticed that you can only pass log messages as a String and
    not as an object. Also I saw that Formatters format "around" this
    String. I think that is quite a limitation for my purpose.
    
    What's if I have different Log Formats, which I would like to apply.
    For example, there are different levels of verbosity. The apache log
    format "combined" sends more output then "common". Maybe I also want to
    define my own custom ones.
    
    Then I would like to have a Formatter for each output Format. Do do
    that, however, Formatters would have to be able to work on those HTTP
    objects, which contain the fields.
    
    That does not seem to be possible under the current logging API or am I
    missing someting here? I really don't understand, why the message is
    not being stored as an Object but a String - that only limits the use
    of the Formatter.
    Can somebody elaborate on this. Maybe it should be brought up with Sun?

  - Creating HTML files from Java accessing OracleHello folks,
    I have some queries that folks would like to have as HTML reports. At
    first I tried Oracle Reports but it's HTML output seems really poor

    (I use Jdev as my IDE right now.) but was hoping someone might have
    some insight on the best way to tackle this. I guess I am looking for
    methods that would make things easier rather than just outputting
    print commands line by line. :)

  - Runtime.exec and socketsI submitted this as a bug, but no response. Can anyone help?
    
    FULL PRODUCT VERSION :
    java version "1.4.1"
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
    Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)
    
    ADDITIONAL OS VERSION INFORMATION :
    Microsoft Windows 2000 [Version 5.00.2195]
    
    A DESCRIPTION OF THE PROBLEM :
    Runtime.exec() to start a new java program. The new java program
    should create a socket connection to another program.
    
    The socket will connect if created and used from the static main
    method. It will also work if placed in a static method called from
    main. It will not work if I create an object and have the object
    execute the same code (which is what I need); it fails both times if
    the method is static or not static.
    
    If I run the java program from the command line and not by using
    Runtime.exec, it works beautifully.
    
    If while it is blocking I kill the first vm, then the second vm
    continues.
    
    ACTUAL -
    Blocking
    
    REPRODUCIBILITY :
    This bug can be reproduced always.

    Runtime rt = Runtime.getRuntime();
    Process p = rt.exec("java ProgB");

    System.out.println("Process Returned");

  - i18n in Swing, trouble.Hi,
    
    I am building my first Gui with Swing, and in the same time I need to
    use the i18n to make it work in Japanese and English.
    
    I use Eclipse and its great Visual Editor to save time, all my files are
    utf8 encoded. And, I am under WinXp...
    
    My trouble is the following :
    -> If I make a jMenu with some japanese hardcoded text, it appears fine
    in my application.
    -> If I use a ResourceBundle to get the text, I have garbage. I use the
    following line: myMenu.setText(myBundleResource.getString("myTest"));
    The .properties files for the japanese is also in Utf8
    
    Do you have any idea why the text in the .properties file is not passed
    correctly ? Any help would be really appreciated.
    
    Best Regards,
    Schlum

  - Sending XML as a String through a web service (Tomcat/AXIS)?Hi, I have a web service written with Tomcat/AXIS. One of my
    methods receives a String. Is it possible to send a String of
    XML through this method? Will the XML tags confuse the
    underlying web service system? Or will the XML be "escaped"
    (with the <, > characters rewritten somehow)?
    
    Thanks.

  - JSP vs XSLT?Which is better JSP or XSLT? I prefer JSP for two reasons performance
    and less complicated to learn.
    
    JSPs are compiled one time, then cached, unless the code changes. This
    not the case with XSLT, as I understand it.
    
    XSLT is very complicated to learn, in my opinion.
    
    See this article by IBM on JSP vs XSLT:

  - Interrupt on Java thread..I have two threads, one reading from stdin and writing to a socket
    (requestThread),
    one reading from a socket and writing to stdout (responseThread).
    
    When the response thread gets a msg from server that an error occurs, it
    closes the socket and calls interrupt() for it's thread group before
    exiting.
    
    But requestThread never seems to get the interrupt.
    It is blocked(?) on a readLine() from the BufferedReader omn stdin.
    
    What am I doing wrong?

  - Trusting ceritificates where CN does not match website hostnameJDK 1.4.2_08
    
    I am getting the following exception:
    
    javax.net.ssl.SSLHandshakeException:
    sun.security.validator.ValidatorException: No trusted certificate found
    at com.sun.net.ssl.internal.ssl.BaseSSLSocketImpl.a(DashoA12275)
    at com.sun.net.ssl.internal.ssl.SSLSocketImpl.a(DashoA12275)
    at com.sun.net.ssl.internal.ssl.SSLSocketImpl.a(DashoA12275)

    at com.sun.net.ssl.internal.ssl.SSLSocketImpl.j(DashoA12275)
    at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(DashoA12275)
    at
    org.apache.axis.components.net.JSSESocketFactory.create(JSSESocketFactory.java:224)
    
    I have imported the certificate into the cacerts file via keytool -import.
    
    However, my problem is that, the operator has setup a development and
    production website, where the hostname naturally differs ... but both
    development and production URLs have the same certificate.
    
    That is, the production, Verisign-signed server certificate is the same
    certificate on the development website. This ceritificate, therefore, has
    the common-name ( CN ) set to the hostname of the production website.
    
    Thus, even if I import the certificate into the cacerts file, because the
    server certificate' CN does not match hostname of the website, I get the
    exception above when connecting to their development website.
    
    Apart from implementing DummyTrustManager as per this article:
    
    http://www.javaworld.com/javatips/jw-javatip115.html
    
    ... which I'd rather not, is there any other workaround ??
