  - JAVA RMI thr HTTP throws NoRouteToHostExceptionHi,
    
    I am developing an application that would be used in a firewall
    environment. As part of my test environment, I have blocked port 1099
    and have allowed port 80 access on the server. So all the RMI calls
    from the client should be tunnelled thru port 80 in the server.
    
    I have ported the java-rmi.cgi script (unix version) to windows
    version. So I am confident that my RMI client, java-rmi.cgi are
    correct. But I am getting NoRouteToHost Exception and my application
    has to exit.
    
    My understanding is that when the RMI client tries to connect 1099 (rmi
    port) and if it fails, it will try to connect to port 80 and later all
    the rmi calls should be embedded within http commands. Does my
    web-server (apache) needs to be configured for this?
    
    I have also tried setting http.proxtHost, but of no avail.
    
    Please let me know of your solutions.

  - Eclipse 3.1 crash on sun's jvmHi list,
    
    Eclipse just crashed the jvm when I ran it.
    
    the jvm dump suggest that the gtk smooth lib is to be blamed.
    
    since this happened to me twice on two different machines, I think it
    may (or have already) happen(ed) to many other people.
    
    after removing gtk2-engines-smooth eclipse started to work again.
    
    snippet from the jvm dump file:
    
    Native frames: (J=compiled Java code, j=interpreted, Vv=VM code,
    C=native code)
    
    C [libc.so.6+0x66533]
    C [libc.so.6+0x66af2] __libc_free+0x82

  - Accessing a Java COM component from .NET.NET framework 1.2
    
    Hello.
    
    We've been accessing a Java COM component from classic ASP for a while now,
    which works fine. We now need to access it from .NET, but we have no idea
    how to reference this component as we can't find the .dll (or whatever type
    of file Java COM components compile to). We do know a couple of things
    about the component:
    
    CLSID: {E7DEFE93-E26E-11d2-B3A0-0000E8512796}
    Component name: PaymentClient.com.COMClient
    
    Searching the registry for either string yields results, but the only DLL
    referenced is msjava.dll which is obviously not what we're looking for.
    
    Can someone give us any hints on how to access this object from .NET.
    
    Thanks,

  - Design question: business delegate or not?L.S.,
    
    We're in the process of developing an application using JSF, Hibernate and Spring and we're facing a design question on which we would like your ideas.
    The application has it's own database, which is accessed using Hibernate, for most of it's entities (e.g. Problem), but it also has to work with data from a legacy system.
    
    The legacy data is accessed through a set of Spring components (<bean/>s), which use JMS to exchange XML messages with the legacy system. These services provide us with e.g. Article instances.
    
    The Problem instances, which are retrieved using Hibernate, should hold a reference to an Article. Since Hibernate does not know about the Article class, we have added an articleId property to the Problem class and whenever we retrieve a Problem using our ProblemService class, the ProblemService will look at this property and retrieves the corresponding Article instance.
    This process happens for a couple of entities (Article, Supplier, TracingInformation, ...)
    
    This approach however has a number of drawbacks:
    1) our Problem class contains several 'duplicate' properties: articleId/article, supplierId/supplier,... leading to confusion
    2) resolving the correct Article, Supplier, ... instances happens for every Problem ever instantiated in the ProblemService, causing overhead whever the information is not required by the JSF web client (especially for lists of data)
    3) whenever someone adds functionality to the ProblemService, we have to be careful to always fill in the missing entities when a new Problem instance is created
    
    We have thought of two possible solutions so far:
    
    1) creating a Hibernate UserType to convert the article id stored in the database to an Article instance and visa versa
    - This approach would solve drawbacks 1 and 3, but doesn't help us much with drawback 2.
    - There is another issue with this approach: we need Spring's ApplicationContext in our UserType (<type .../> declaration in Hibernate mapping), but this would require rebuilding the ApplicationContext or having some kind of singleton to obtain the ApplicationContext (it is now created by a web application listener) (unless there is a Spring way of doing this, e.g. using a TypeDefinitionBean)
    
    2) creating a business delegate for the Problem class
    - This would solve all drawbacks, since the business delegate could quite easily use the Spring components already available to retrieve an Article instance on the fly when needed
    - The business delegate should only have to expose the article property and the object sent to our DAO should only contain the articleId
    - The business delegate solve the resolving of the Article, Supplier, ... entities once and for all, so nobody can forget to add these to their newly created Problem instance
    
    The 'Business Delegate' solution seems the most appropriate, but wouldn't it add a considerable amount of extra coding for the features it provides?
    Which solution would you recommend? Do you see an easier solution for the problem?
    
    Thank you in advance for any feedback,

  - identical JPanels, repetitive
    I need to make a tabbed pane with four tabs, each pane shows text and
    images from a List<Room> collection.
    
    I can manually create the four tabs from the netbeans GUI builder, and
    maybe use some copy paste so that the four tabs are similar if not
    identical.
    
    Staying within the GUI builder, how would four identical JPanel's, which
    make up the tabs for a JTabbedPane, get created?
    
    Could I somehow make a JList show as tabs?
    
    thanks,

  - Difference in opinion with look and feel !Hi,
    
    I have an interesting problem while using the look and feel. This is my
    function:
    
    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    
    Well the tool bars, the menu are all system's look and feel. i.e i am
    using Windows OS. so i get all windows look and feels. But when i use
    the file chooser, I get an open dialog box with look and feel of Sun
    Microsystems' solaris.
    
    Does anyone have any idea why this is coming up like this?
    Interestingly I am not even able to reproduce this an other project.
    Plz help,
    
    Thank you,

  - Displaying error values with Struts Validator FrameworkHi,
    
    I'm using the struts validator framework to validate an email address
    in a form.
    If the user enters an invalid email address (ie
    invalidEmailAddress.com) I'd like to display the following error
    message:-
    
    "invalidEmailAddress.com is an invalid e-mail address"
    
    However all I seem to be able to do with the validator framework is
    output the following:-
    
    "Email address is an invalid e-mail address"
    
    with messageResources.properties and validator.xml set as follows:-
    
    validator.xml:-
    <form name="addressForm">
    <field property="emailAddress"
    depends="email">
    <msg name="email" key="errors.email" />
    <arg name="email" key="form.address.label.emailAddress" />
    </field>
    </form>
    
    messageResources.properties:-
    errors.email={0} is an invalid e-mail address.
    form.address.label.emailAddress=Email address
    
    I'm using <html:errors /> to output the error list in a jsp.
    
    Is there any way to substitute the actual entered value into the
    errors.email message using the struts validator framework? I know it
    can be done in the validate() method of the ValidatorForm class but
    it there method of simply using the validator framework?
    
    Thanks in advance for your help.

  - How Do I Configure a Tomcat Server for Production?Hello,
    I am pretty new to Tomcat. I am wondering if there are any standard
    configurations that need to be added/modified as part of a Production
    deployment aside from database URLs and those types of values.
    Currently, we have mostly the same configuration for Production as we
    do for development.
    
    As the load increases are there any obvious values that we should be
    changing?
    
    Thanks, Jesse

  - How to create same RSA signature objects in Java and C#Hello,
    
    I have looked through the documentation for the Java and C#
    security classes, and I can't find an answer to the following question.
    
    How can the same RSA signature object (class java.security.Signature in
    Java
    and System.Security.Cryptography.RSACryptoServiceProvider in C#)
    be constructed?
    
    What I would like to see is that signatures generated in Java are
    recognized as valid by C#, and vice versa. I am assuming this implies
    that the RSA signature parameters must be the same in both
    languages, but I can't figure out how to make that happen.
    
    According to some sketchy notes I've found through googling,
    it is possible, so I'll keep trying. Thanks for any information.

  - Java server accessI have a javaApplet that needs to access a directory on the server, list
    the files in directory, then access the selected file. My first idea
    was to use a servlet on the server then I found out that the server that
    this needs to work with doesn't support servlets or Tomcat. The server
    supports PHP and CGI and the hosting company does not want to add java
    support.
    Can anyone give me an idea on how to go about this?

  - JavaScript redirect and JSP submitHi,
    
    I've been trying to get the right way to send parameters to a JSP from
    a HTML form. The referred JSP must get the values of the selects form,
    because it executes queries and does stuff with that values. But the
    only thing I've got it's a Tomcat error report.
    
    The menu.jsp is something like this:
    
    ... // HTML stuff
    <script language='JavaScript'>
    function valida()
    {
    var ok=true;
    var indexAccion = document.forms[0].accion.selectedIndex;
    var indexTablas = document.forms[0].tablas.selectedIndex;
    var indexBDatos = document.forms[0].BDatos.selectedIndex;
    if (indexAccion==0 || indexTablas==0 || indexBDatos==0)
    {
    alert("Elige un criterio");
    ok=false;
    }
    if (ok)
    document.forms[0].submit();
    window.location.href =
    document.forms[0].accion.options[indexAccion].value;
    }
    </script>
    
    ... // HTML stuff
    
    <form method='post' ***SHOULD BE THE accion.selectedIndex.value***>
    <select name="accion">
    <option value="inicio" selected>Selecciona una opcion

    </select>
    <select name="BDatos">
    <option value="inicio" selected>Selecciona una base

  - Nio performance bottleneckHello !
    
    In order to be sure that nio package was more performant than regular
    streams, i have tested it with this little piece of code :
    
    // ----------------------------
    ByteBuffer loWriteBuffer = ByteBuffer.allocateDirect(1024);
    CharBuffer loBuffer = CharBuffer.allocate(512);
    
    Charset charset = Charset.forName("ISO-8859-1");
    CharsetEncoder encoder = charset.newEncoder();
    long llMillis, llMillis2, llMillis3;
    
    llMillis = System.currentTimeMillis();
    try {
    FileChannel loChannel = new RandomAccessFile(new
    File("C:\\Temp\\Test.txt"), "rw").getChannel();
    for (int i = 0; i < 1000; ++i) {
    loBuffer.put("ceci est un test\r\n");
    loBuffer.flip();
    encoder.encode(loBuffer, loWriteBuffer, false);
    loWriteBuffer.flip();
    loChannel.write(loWriteBuffer);
    loBuffer.clear();
    loWriteBuffer.clear();
    }
    loChannel.close();
    }
    catch (IOException leIO) {
    leIO.printStackTrace();
    }
    llMillis2 = System.currentTimeMillis();
    try {
    Writer loWriter = new BufferedWriter(new OutputStreamWriter(new
    FileOutputStream("C:\\Temp\\Test2.txt"), charset));
    for (int i = 0; i < 1000; ++i) {
    loWriter.write("ceci est un test\r\n");
    }
    loWriter.flush();
    loWriter.close();
    }
    catch (IOException leIO) {
    leIO.printStackTrace();
    }
    llMillis3 = System.currentTimeMillis();
    
    System.out.println("Results : nio = " + (llMillis2 - llMillis) + " ms /
    standard = " + (llMillis3 - llMillis2) + " ms");
    // ----------------------------
    
    I was surprised to see that, on my computer, the regular stream based part
    was running about 4 times quicker than the nio based part !!
    Here is my question : is my code correctlty optimized ? Anybody already
    noticed this performance bottleneck ? Is my test the cause of this problem ?
    
    Thank you !

  - Database access for server and clientI am trying to create a small Internet application to access a mySQL
    database on specific client machines around the country and query their
    database and send the query result to our web server and then process
    further data on the web server. Here is the layout: There are
    several client machines around the country that have a mySQL database
    installed and will give us certain query privileges for this database.
    I need users on these client machines to be able to run an Internet
    application from our web server which queries their local database and
    then sends information to our server.
    
    I see two options: a trusted, signed applet or a full java application
    - also digitally signed - that is deployed through the Java Web Start
    technology. (This is a very simple query on the client with a simple
    drop-down list for the user to select from the query result - nothing
    complicated.)
    
    Does anybody have any suggestion as to which method is preferable? The
    end users who will be running this application are not very computer
    savvy and might not be able to figure out browser messages like "Your
    browser understands the <APPLET> tag but isn't running the applet, for
    some reason." For this reason I thought that the Java Web Start method
    might be preferable, but I have no idea how reliable this method is and
    what kind of kinks I will have to work through.
    
    I also wonder if the Microsoft .net environment might offer an
    alternative (our web server is Microsoft IIS and the clients are all
    Windows XP or Windows 2000).
    
    Any thoughts?
    
    Thank you.

  - Samsung Blu-ray pre-orders incredible: Java Blu-ray authoring in high demandNotes on initial responses to Samsung blu-ray launch, people already
    buying players before content, and Java BD-J authoring of Blu-ray discs
    
    * Posted while eating late lunch on Nokia 9300 and Opera Mini Java
    browser.
    
    http://bluray.highdefdigest.com/news/show/Sony/Samsung/Hardware/Blu-ray_Assault_to_Begin_Samsung_Proclaims_Incredible_Pre-Sales/111
    
    Blu-ray Assault to Begin; Samsung Proclaims 'Incredible' Pre-Sales
    
    After months of speculation, excitement and street date delays, the
    Blu-ray
    format is set to launch over the next week amid a flurry of marketing
    hype
    for the format's first player and discs.
    
    Samsung began shipping its first stand-alone Blu-ray disc player, the
    BD-P1000, to stores last week in anticipation for its on-sale street
    date of
    June 25. Sony will prime the pump for the player's debut by issuing
    its
    first seven Blu-ray disc titles tomorrow, June 20; Lionsgate will
    launch its
    support for Blu-ray with another six titles on June 27.
    
    Samsung plans to have its player in over 2,000 storefronts nationwide,
    including such major chains as Best Buy and Circuit City. In
    conjunction
    with Sony, the companies will also provide demo players and discs to
    retailers to offer side-by-side comparisons with rival HD DVD in order
    to
    subjectively sell the format to potential consumers.
    
    The electronics manufacturer also claims that interest in the BD-P1000
    and
    Blu-ray so far has been strong. "Pre-orders have been incredible,"
    Samsung
    spokesman Jose Cardona told Video Business.
    
    ---------------------------------------------
    
    http://www.tgdaily.com/2006/06/20/sony_pictures_blu-ray_movies_today/
    
    With Toshiba having launched its HD-A1 and HD-XA1 HD DVD videodisc
    players
    in April, Samsung is preparing to be the first brand to formally
    launch a
    competitive Blu-ray Disc player in North America, with its BD-P1000
    set to
    premiere on Sunday. Despite that firm date, customers nationwide are
    already reporting having purchased BD-P1000s from Best Buy store
    shelves -
    just sitting there nonchalantly like any other DVD player, as if shelf
    stockers didn't know the difference. But today, those early adopters
    will
    finally be able to play real BD media - not just upconverted SD media
    - as
    Sony Pictures releases the first batch of BD movies today.
    
    Video outlets today should already have received, and will likely have
    displays ready for, 50 First Dates (Adam Sandler, Drew Barrymore),
    Hitch
    (Will Smith), House of Flying Daggers, the original Terminator, the
    sci-fi
    "new cult classic" The Fifth Element (Bruce Willis), Underworld
    Evolution,
    and XXX (the film, not the rating). One title, A Knight's Tale,
    originally
    scheduled for release today, is being pushed back to 25 July. The
    high-energy motorcycle violence film Ultraviolet joins the line-up
    next
    Tuesday. Lion's Gate Home Entertainment is due to follow up next
    Tuesday
    with the BD releases of 2006 Best Picture Crash, Terminator 2:
    Judgment Day,
    the horror flick Saw, Lord of War (Nicholas Cage), and the Marvel
    Comics
    vigilante piece The Punisher.

    Java: Brave New Disc-Authoring World
    http://www.pcworld.com/news/article/0,aid,126163,00.asp
    
    Blu-ray Disc relies on BD-Java (BD-J) for its disc-authoring
    environment;
    HD DVD uses Microsoft's XML-based iHD, or Internet High Definition. "I
    think
    BD-J is better future-proofed," says Eklund. "But it is complex," and
    implementing it properly will take more time, he says.
    
    The switch to BD-J required adding programmers and engineers to the
    disc-production mix.
    BD-J has two different profiles. Sony's first content will be in what
    Eklund
    refers to as BD-MV, or "movie mode." "The menus will still be quite
    different than what you're accustomed to with DVD," he promises.
    "BD-MV is a
    powerful format for creating interactive menus, and it will give a
    better,
    more seamless experience than what users are getting from DVD. You
    don't
    have to jump around between menu pages as you do with DVD. We use a
    graphics
    layer to present all of the text information, so you don't have to go
    back
    and access the disc in order to access the menus. We also have a tool
    called
    a pop-up menu that the user can use to access disc features during the
    movie's playback, so, for example, you can get to a commentary track."
    
    As powerful as BD-MV is, it has its limitations. "We are currently
    still
    investigating how we're going to author picture-in-picture content,"
    says
    Eklund. "But I'm sure we will be exploring that later on in the year."

java-programmer, Suspending threads by ThreadPoolExecutor Hi all,

Does ThreadPoolExecutor may suspend idle threads ?
I wonder wether suspended threads eat less resources than active ?

I imagine the solution when ThreadPoolExecutore suspends each idle
threat after idleness of 60 seconds and after next 60 seconds of being
suspend the thread got killed ?

Is it reasonable ?

Regards,

Maciej

If the thread is idle, what would the point of suspend be?
Thread.suspend is deprecated for very good reason.

  - Encryption & DecryptionHi all
    
    I've been asked to look into the encryption and decryption of attachments
    sent in emails. The specific scenario is as follows:
    
    - a file is created
    - the file is to be encrypted
    - the file is attached to an email and sent to a recipient
    - once received, the file should be decrypted
    - the file is read
    
    At first glance, I think I should be reading up on the JCA (Java
    Cryptography Architecture) and use a public key encrypt and a private key to
    decrypt. Is this right?
    
    Are there any online implementations or tutorials that you would suggest I
    read to learn more about this?

  - Export ApplicationHello.
    
    I am using Netbeans 3.5 IDE and have created several applications which is
    fine and dandy. The only thing I cannot do is work out how to export these
    apps to another PC i.e. to run them on a machine without having the IDE
    installed. I believe this would be via a JAR file but cannot seem to get
    these to work. Any help in this area would be great as I am going round in
    circles. Also, how do I encrypt the code ?

  - Making Form results readableI have coded a simple form that sends the results to an email. The
    form works, but when I recieve the data it is all together in one big
    line. What kind of coding do I need to do to separate the data and
    label it as well. Do I need to create some sort of template in
    notepad??? I am a very beginner coder.
    
    Thanks,

  - Focusing a JPanel?Is there a way to give a JPanel focus on a mouse click besides explicitly

  - GUI Object DesignI am pretty new to Java and I am trying to get my hands around OOD.
    
    In the course of designing a GUI, I am working on breaking down the
    components into the necessary objects so that the code will be as
    versatile as possible.
    
    As I work through it though, I am confronted with the situation where
    I feel that I am over analyzing and creating too many objects.
    
    Let's say that I have a pretty basic window application. It has a
    window with a menu bar and three menus, each with a few items.
    
    The main window is an object inherited from JFrame.
    
    Is it best to make the menu a seperate object, inherited from
    JMenuBar, and then make each menu a seperate object, inherited from
    JMenu, and then make each menu item a seperate object, inherited from
    JMenuItem? Or, is a lot of this typically placed within a single,
    larger object?
    
    I guess I am wondering where you draw the line. How do I know when I
    have gone too far and am creating too many objects unnecessarily?
    
    I imagine a lot of this dicussion is personal preference and some
    aspects are open to debate. I am just looking for some guidance as I
    learn more about this.
    
    Thanks.

  - Runtime.getRuntime().exec causing Windows 16-bit error!Hi there,
    
    I'm trying to do something i've done many times before without problem, even
    from signed applets...
    trying to run a system command from Java.
    
    I'm doing this:
    
    import java.io.*;
    public class SysCommand{
    public static void main(Stirng[] args){
    try{
    Process proc =
    Runtime.getRuntime().exec(
    new String[]{"command.com",
    "/C",
    "echo",
    "%windir%"});
    BufferedReader reader =
    new BufferedReader(
    new InputStreamReader(
    proc.getInputStream()));
    System.out.println(reader.readLine());
    proc.waitFor();
    proc.destroy();
    }
    catch(Throwable th){
    th.printStackTrace();
    }
    }
    }
    
    I'm trying to find out where the Windows directory is (i need to copy some
    DLL's into there as part of an installation process).

  - Problem with deploytool.I am trying to build a web service starting from hand-written wsdl using
    JAX-RPC and wscompile tool from Sun Java System Application Server 8.0.
    I don't want any data binding, so i invoke wscompile tool with -f
    nodatabinding option with deploytool I create war, and I try to deploy it.
    
    And deployment fails!
    Reading server log I have found that reason for this failure is ejbc:
    
    [#|2004-09-29T21:09:41.174+0200|INFO|sun-appserver-pe8.0.0_01|javax.enterprise.system.stream.out|_ThreadID=11;|
    error: [failed to localize] unable to find member rodzajProblemu in
    jaxrpcmapping meta for exception whose wsdl message is:
    {http://www.eAdministracja.gov.pl/wsdl/ZDGUsluga}problemPrzetwarzania|#]
    
    Message refers to part of my schema cited below:
    
    <schema
    xmlns="http://www.w3.org/2001/XMLSchema"
    xmlns:ug="http://www.eAdministracja.gov.pl/UrzadGminy/typy"
    targetNamespace="http://www.eAdministracja.gov.pl/UrzadGminy/typy">
    
    <complexType name="ProblemPrzetwarzania">
    <sequence>
    <element name="rodzajProblemu">
    <simpleType>
    <restriction base="string">
    <enumeration value="Merytoryczny"/>
    <enumeration value="Systemowy"/>
    </restriction>
    </simpleType>
    </element>
    <element name="oznaczenieProblemu" minOccurs="0" type="string"/>
    <element name="opisProblemu" type="string"/>
    </sequence>
    </complexType>
    
    <element name="problemPrzetwarzania" type="ug:ProblemPrzetwarzania"/>
    
    </schema>
    
    Identifiers are polish words, so don't bother with making up what do
    they mean.
    I have checked mapping.xml generated by wscompile, and ejbc is right -
    there is nothing about rodzajProblemu, but if there is no class bound to
    element problemPrzetwarzania except SOAPElement, there is no mapping,
    so deploytool shouldn't try to compile any bean!
    
    Should I consider it to be bug or I am doing sth. wrong?

  - Eclipse Runtime ErrorI am running Eclipse 3.1.1. I created a project, called PizzaShop.
    Inside pizza shop, I have src\ lib\ and build\classes\ folders. Inside
    src\, I have a pizza folder for the pizza package. That too is mirrored
    in build\classes\pizza.
    
    When I go to debug as ->debug, Eclipse tells me:
    
    java.lang.NoClassDefFoundError: pizza/SystemTest
    Exception in thread "main"
    
    What does that mean and how do you tell Eclipse which main to run? I
    think I tell it that when it pops open the configuration menu, and I
    tell it "pizza.TakeOrder" for the main class to run. But, obviously, it
    cannot find the main, and there is a public main() in the TakeOrder
    file.
    
    So confused, Scott

  - adjusting boundries of JPanels in JPanel in JFrameHi, I tried searching through the google groups, but am obviously using the
    wrong search words.
    
    I have a JFrame with a JPanel in it. The JPanel is using the following
    layout:
    new BoxLayout (parentPanel, BoxLayout.LINE_AXIS)
    
    Then I added two JPanels to the parentPanel.
    
    But then I would like to click and drag the separator between the two panels
    to change the size of the two JPanels.
    
    Any hints?
    
    Thanks,
