Need Classes help......

Hi all,
i was wondering if anyone can help me out with my code.
i've got a class Desktop, and a class menu.
the class Desktop contains the following...
public class Desktop extends JFrame implements ActionListener{
protected JDesktopPane  thedesktop;
protected JMenuBar jMenuBar1;
protected ..........and all elements declared here..
public Desktop(){
super("application");
menu mymenu = new menu(); //class will build the menubar
setJMenuBar(jMenuBar1); //adds menubar to jframe
bla bla.......
public static void main(String args[]){
Desktop app = new Desktop(); //call constructor
}the class menu is as follows
public class menu extends Desktop{
public menu() {
jmenubar1 = new JMenuBar();
//add all items to jmenubar1
//all menus etc are declared in desktop, and initalized here
// as this class extends desktop class
}in desktop, i want the class menu to build the jmenubar for me,
the i add the jmenubar with the line..setJMenuBar(jMenuBar1);
both classes compile with no errors, but will not run, stalls on the commandline.
can anyone see what i'm doing wrong ???
it's something to do with the second class extending Desktop, and calling that constructor.
is there a way around my problem ???
thank you so much
Paul

Why don't you try this another way
public class Desktop extends JFrame implements ActionListener{
         protected JDesktopPane thedesktop;
         private Menu myMenu;
      public Desktop(){
             super("application");
              myMenu = new Menu(); //class will build the menubar
              setJMenuBar(myMenu.getMenuBar() );// call to the method in class Menu that will return a menubar
public static void main(String args[]){
            Desktop app = new Desktop(); //call constructor
class Menu extends Desktop{
     JMenuBar menuBar;
public menu() {
        menuBar = new JMenuBar();
        // and all your stuff here
public JMenuBar getMenuBar(){
        return menuBar;
}

    How do I put a class inside a class?
    I want to make a gui class, and then inside it have the class with strings, etc.
    How would I go about doing that?
    If anyone can show me code for a simple gui with like 3 text boxes, and a button that would be much appreciated. Thank you.

    hmm .... u could also look at
    http://java.sun.com/docs/books/tutorial/java/javaOO/innerclasses.html
    assuming u wish to understand how to have a class within another class. Also pls. do look at the swing tutorial for a clearer more in depth understanding of the gui subject.

  • GUI swing class help needed

    hi, i just need some help to create a bar kind of object (like a bar of battery shown in mobile phones).
    the information i have is in percentage from 0-100%. and what i have planned is that:
    the bar will be split into four:
    from 0-25: one bar will be colored green.
    26-49 "
    50-74 "
    75-100
    the bar information will be from the battery left percentage as mentioned above.
    also if the battery is below 25% the GUI should give an alert (possible red screen with big "alert"..)
    I started doing the frame but got stuck on the bar. pls can you help.
    im looking for nothing complex like make it very accurate to each value of infor. thanks

    Hi,
    You can use a JProgressBar (min 0 max 4)...
    Or make a custom bar with some filled rectangles ...

    I am sorry if the Gradients were a bit confusing and they weren't exactly what you were asking for but that is what I did for my program.
    What you will do is that your meter will have basically 4 Rectangle objects.
    The logic to determine which Rectangles you will paint to the screen will intuitively go into the paint(Graphics g) method.
    Pseudo-Code:
    public void paint(Graphics g) {
      //set desired color on graphics context
      //switch percentage
      //case percentage = 100
      //fill Rectangle1
      //case percentage <= 75%
      //fill rectangle 2
      //case percentage <= 50%
      //fill rectangle 3
      //case percentage <= 25%
      //fill rectangle 4
      //end switch
    Keep in mind not to put break statements in your switch so that all necessary blocks get colored.

  • Need your help on performance issue please

    Hello everyone!
    I need your help to understand an effect I notice with a Thread class I built. I currently work on enhancement of my application Playlist Editor (see http://www.lightdev.com/page74.htm) and a new release will be available soon.
    Among other extensions the new release will have a title filter function which is based on audio data that is recursively read from ID3 tags of files found in a given root directory. The data collection is done by a CollectionThread class which reads into a data model class AudioDataModel and the entire process works fine, no problem with that.
    However, when my application is started for the first time the CollectionThread runs approximately 3 minutes to collect data from approximately 4300 audio files on an Intel Pentium M 1,4 GHz, 512 MB RAM, Windows XP SP2. When the application is shut down and started again, it takes only a few seconds to do the same task for all subsequent launches.
    I already tried to start the application with java option -Xms40m to increase initial heap size. This increases performance in general but the effect is still the same, i.e. first run lasts significantly longer than subsequent runs.
    I also tried to build a pool mechanism which creates many empty objects in the data model and then releases them to contain the actual data at is being read in but this did not lead to better performance.
    It must have to do with how Java (or Windows?) allocates and caches memory. I wonder whether there is a way to pre-allocate memory or if there are any other ideas to improve performance so that the process always only takes seconds instead of minutes?
    I attach the key classes to this message. Any help or ideas is much appreciated!
    Thanks a lot a best regards
    Ulrich
    PS: You can use the news subscription service at
    http://www.lightdev.com/dynTemplate.php4?id=80&dynPage=subscribe.php4 to be informed when the new release of Playlist Editor is available.
    All classes posted here do not need debugging, they already have proven to run error free. The classes are only posted for information for the interested reader - no need to go through all the stuff in detail - only if it interests you.
    My application calls class CollectionThread wich is a subclass of InfoThread. CollectionThread recursively goes through a directory and file structure and stores found ID3 tag information in instances of class ID3v11Tag which in turn gets stored in one instance of class AudioDataModel. All classes are shown below.
    This is the mentioned CollectionThread

    Hi Franck,
    thank you, mate. I did what you suggested (changed class attached) but that did not change the mentioned behaviour.
    The first run is approximately 75 seconds with Java option -Xms40m and approx. double without, the second run and all subsequent runs are only 2-3 seconds each (!!!) even when terminating and re-starting the application between thread runs.
    I'm pretty clueless about that, any more help on this anyone?
    Thanks a lot and best regards
    Ulrich
    PS: BTW, I forgot to post the class that is filled with data by class CollectionThread, so here it is

  • I need Fusion help creating a demo of BRM JCA Resource Adapter

    I need Fusion help creating a demo of BRM JCA Resource Adapter.
    I know BRM well but am clueless with Fusion.
    I am trying to figure out what Fusion products to download and install and how I manipulate the Fusion side to manipulate BRM.
    My BRM docs say:
    Installing the BRM JCA Resource Adapter ->
    Software requirements
    (yada yada install a bunch of BRM stuff I know how to do)
    The adapter must be deployed on a J2EE 1.4-compliant application server that has implemented the JCA 1.5 specification. The adapter runs only in a managed environment. (Does this imply some particular Fusion package?)
    (more yada yada about installing more BRM packages I know how to do)
    Deploying and configuring the BRM JCA Resource Adapter ->
    Overview of the BRM JCA Resource Adapter configuration procedure
    The procedure for setting up the BRM JCA Resource Adapter includes the following tasks:
    Installing the adapter on your BRM system, if you have not already done so. See Installing the BRM JCA Resource Adapter.
    Generating the schema files for the adapter. See Generating the schema files for your system. (links to some BRM commands np)
    Specifying how to construct XML tags. See Specifying the XML tags for extended fields. (links to an oob file included with directions on how to address BRM customizations np)
    Generating the WSDL files for the adapter. See Generating the WSDL files for your system. (links to an oob file with directions to configure. I could use some help if/when I get this far)
    The last two look pretty important but I haven't a clue. I pasted the text from the docs below.
    Deploying the adapter on your application server. See Deploying the BRM JCA Resource Adapter on an Oracle application server.
    Connecting the adapter to the BRM software. See Connecting the adapter to BRM in Oracle AS.
    Deploying the BRM JCA Resource Adapter on an Oracle application server
    The adapter is dependent on Java Archive (JAR) files to deploy properly. The following table lists the JAR files that the adapter requires from each application in your system.
    Application
    JAR files
    J2EE application server
    classes12.jar, connector15.jar, and jta.jar
    Oracle BPEL process
    bpm-infra.jar, orabpel-thirdparty.jar, orabpel.jar, and xmlparserv2.jar
    BRM J2EE Resource Adapter
    pcm.jar and pcmext.jar
    Apache
    xercesImpl.jar
    If you are deploying the adapter in a standalone Oracle Containers for Java EE (OC4J) instance, make sure these JAR files are available to the class loader that is loading the adapter.
    If you are deploying the adapter by using Oracle SOA Suite, these JAR files are available as part of the oracle.bpel.common code source. You import these libraries as follows:
    Open the Oracle_home/j2ee/Instance/config/applications.xml configuration file for the J2EE instance.
    Add the oracle.bpel.common entry (shown in bold below) to the imported-shared-libraries section of the file:
    <imported-shared-libraries>
    <import-shared-library name="adf.oracle.domain"/>
    <import-shared-library name="oracle.bpel.common"/>
    </imported-shared-libraries>
    Save and close the file.
    Restart the application server or the J2EE instance.
    After you make the JAR files available, deploy the adapter on the Oracle application server by using either the Oracle Application Server (Oracle AS) Application Server Control (ASC) or the Oracle admintool.jar file. Copy the adapter archive file (BRM_home/apps/brm_integrations/jca_adapter/OracleBRMJCA15Adapter.rar) from the installation directory to a location that is accessible to the adapter deployment tool. You can then open and deploy the archive file on your application server.
    After successful deployment, return the applications.xml file to its original settings and add the oracle.bpel.common codesource to the BRM Adapter oc4j-ra.xml file:
    Open the Oracle_home/j2ee/Instance/config/applications.xml configuration file for the J2EE instance.
    Remove the following oracle.bpel.common entry (shown in bold below):
    <imported-shared-libraries>
    <import-shared-library name="adf.oracle.domain"/>
    <import-shared-library name="oracle.bpel.common"/>
    </imported-shared-libraries>
    Save and close the file.
    Open the JCA Resource Adapter oc4j-ra.xml file from the Oracle_home/j2ee/Instance/application-deployments/default/BRMAdapterDeploymentName directory.
    Add the oracle.bpel.common entry (shown in bold below) to the oc4j-connector-factories section of the file:
    <oc4j-connector-factories...>
    <imported-shared-libraries>
    <import-shared-library name="oracle.bpel.common"/>
    </imported-shared-libraries>
    <oc4j-connector-factories>
    Save and close the file.
    Restart the application server or the J2EE instance.
    For more information about deploying the adapter, see your application server’s documentation.
    Connecting the adapter to BRM in Oracle AS
    You connect the adapter to the BRM software by creating connection pools and connection factories. As part of the adapter deployment, the application server creates oc4j-ra.xml from the packaged ra.xml. The ra.xml file is located in the Oracle_home/j2ee/Instance/connectors/AdapterDeploymentName/AdapterDeploymentName/META-INF directory. For example, Oracle_home/j2ee/home/connectors/BRMAdapter/BRMAdapter/META-INF/ra.xml.
    Use the resource adapter home page from the Oracle AS ASC page to create connection pools and connection factories.
    Create your connection pool by following the performance and tuning guidelines in Configuring Connection Pooling in OC4J in Oracle Containers for J2EE Resource Adapter Administrator's Guide. See download.oracle.com/docs/cd/B31017_01/web.1013/b28956/conncont.htm.
    Make sure you set the pool’s Maximum Connections parameter (maxConnections XML entity) equal to or greater than the Oracle BPEL process manager’s dspMaxThreads parameter. For more information, see Oracle BPEL Process Manager Performance Tuning in Oracle Application Server Performance Guide for 10g Release 3 (10.1.3.1.0) at download.oracle.com/docs/cd/B31017_01/core.1013/b28942/tuning_bpel.htm.
    Note To set up JCA Resource Adapter transaction management in BPEL, you must create a private connection pool and set its Inactive Connection Timeout property (inactivity-timeout XML entity) to 0. See About JCA Resource Adapter transaction management in BPEL for more information.
    Create as many connection factories as your system needs. For each connection factory, specify the following:
    The JNDI location for the connection factory.
    The connection pool to use.
    How to connect to BRM by using these entries:
    Entry
    Description
    ConnectionString
    Specify the protocol, host name, and port number for connecting to the BRM software. For example: ip Server1 12006.
    DBNumber
    Specify the database number for the BRM database. For example, enter 1 or 0.0.0.1 for database 0.0.0.1.
    InputValidation
    Specifies whether to validate the input XMLRecord:
    True — The adapter validates the input XMLRecord against the opcode schema.
    False — The adapter does not validate the input XMLRecord.
    The default is False.
    This overrides any other validation parameter specified in the WSDL file.
    OutputValidation
    Specifies whether to validate the output XMLRecord:
    True — The adapter validates the output XMLRecord against the opcode schema.
    False — The adapter does not validate the output XMLRecord.
    The default is False.
    This overrides any other validation parameter specified in the WSDL file.
    LoginType
    Specifies the authentication method:
    1 — The adapter logs in to BRM by using the specified login name and password.
    0 — The adapter logs in to BRM by using the specified service type and POID ID.
    The default is 1.
    UserName
    Specifies the login name the adapter uses for logging in to the BRM software.
    Note This entry is required only if LoginType is set to 1.
    Password
    Specify the password the adapter uses for logging in to the BRM software.
    Note This entry is required only if LoginType is set to 1.
    PoidID
    Specifies the POID ID. This entry should be set to 1.
    ServiceType
    Specifies the service the adapter uses to log in to the BRM software.
    The default is /service/pcm_client.
    You have successfully configured the adapter to connect to BRM.

    Atena,
    We have seen the same error appearing, but it doesn't do any harm. Your application should behave correctly, despite this error message raised by UIX runtime.

  • Anybody who can help me? I really need your help

    I've tried to execute J2ee tutorial examples.
    I don't know why this sample didn't execute...I've already finished to set up J2EE and enviornment variables.
    I was trying this part from j2ee tutorial titled as "Packing Web modules".
    Whenever I type "asant create-war" to make web modules in command window. I always got error.
    Packaging Web Modules(From J2ee tutorial for your information)
    A web module must be packaged into a WAR in certain deployment scenarios and whenever you want to distribute the web module. You package a web module into a WAR using the Application Server deploytool utility, by executing the jar command in a directory laid out in the format of a web module, or by using the asant utility. This tutorial allows you to use use either the first or the third approach. To build the hello1 application, follow these steps:
    In a terminal window, go to <INSTALL>/j2eetutorial14/examples/web/hello1/.
    Run asant build. This target will spawn any necessary compilations and will copy files to the <INSTALL>/j2eetutorial14/examples/web/hello1/build/ directory.
    To package the application into a WAR named hello1.war using asant, use the following command:
    asant create-war
    This command uses web.xml and sun-web.xml files in the <INSTALL>/j2eetutorial14/examples/web/hello1 directory.
    To learn how to configure this web application, package the application using deploytool by following these steps:
    Start deploytool.
    Create a web application called hello1 by running the New Web Component wizard. Select FileNewWeb Component.
    In the New Web Component wizard:

    Thank you in advance.

    ok,
    First of all make sure your tutorial folder is installed from the root:
    C:\javaeetutorial5
    or
    D:\javaeetutorial5
    it makes things so simple.
    Secondly:
    set your jee tutorial home
    JAVAEE.TUTORIAL.HOME =
    C:/javaeetutorial5
    Thirdly: check in:
    C:\javaeetutorial5\examples\bp-project
    make a copy of the build.properties.sample save it as build.propropties, as a property file,
    edit the properties file as in:
    build.properties
    As follows:
    # uncomment the property javaee.home, and add the path
    # to your GlassFish Java EE 5 SDK installation
    javaee.home=c:/Sun/SDK
    javaee.tutorial.home=c:/javaeetutorial5
    # Uncomment the property j2ee.server.username,
    # and replace the administrator username of the app-server
    javaee.server.username=admin
    # Uncomment the property j2ee.server.passwordfile,
    # and replace the following line to point to a file that
    # contains the admin password for your app-server.
    # The file should contain the password in the following line:
    AS_ADMIN_PASSWORD=admin1234and so fourth. Some of the settings as the application server name is all done for you
    and then test it again.
    Take care of editing the property file. It can give you headache.
    Note also that this is for application server 9.1 - JEE5.

  • Please I need some help with a table

    Hi All
    I need some help with a table.
    My table needs to hold prices that the user can update.
    Also has a total of the column.
    my question is if the user adds in a new price how can i pick up the value they have just entered and then add it to the total which will be the last row in the table?
    I have a loop that gets all the values of the column, so I can get the total but it is when the user adds in a new value that I need some help with.
    I have tried using but as I need to set the toal with something like total
        totalTable.setValueAt(total, totalTable.getRowCount()-1,1); I end up with an infinite loop.
    Can any one please advise on some way I can get this to work ?
    Thanks for reading

  • Need some help with a remove function

    Design and code a program that will maintain a list of product names. Use a String type to represent the product name and an array of strings to implement the list. Your program must implement the following methods:
    Add a product to the list
    Remove a product from the list
    Display then entire list
    Find out if a particular product is on the list.
    You need to create a command command loop with a menu() function. The program must continue asking for input until the user stops.
    This is the assignment and this is what I have so far. I need some help writing the remove function.

    I need help removing a product from the arrayYes. So what's your problem?
    "Doctor, I need help."
    "What's wrong?"
    "I need help!"
    Great.
    By the way, you can't remove anything from an array. You'll have to copy the remaining stuff into a new one, or maybe maintain a list of "empty" slots. Or null the slots and handle that. The first way will be the easiest though.

    You can't really believe that his brother did this
    for him...I did miss that copyright line at the beginning when
    I first looked it over, but you know, if it had been
    his brother, I'd be kinda impressed. This wasn't a
    25 line program. It actually would have required
    SOME thought. I doubt my brother woulda done that
    for me (notwithstanding the fact that I wouldn't need
    help for that program, and my brother isn't a
    programmer).I originally missed the comments at the top but when I saw the complexity of what was written then I knew that it was too advanced for a beginner and I relooked through the code and saw the comments.

    i hope it's clear know...If you know some c++, the learning curve doesn't have to be very steep. If you haven't got an IDE yet, that's the first thing to do - Eclipse is free and quite good. Ask it to create a new class, e.g. NumberServer and have the option to create a main method checked. Finish the server part first - you should be able to communicate with it through telnet. Put in a lot of System.out.println so you see what your program is doing, or better yet, learn to use the IDE's debugger - which is good in Eclipse. Read the javadocs for the classes mentioned in an earlier response, and search this forum or Google for their usage if you find the documentation lacking. Then when you have specific problems that you need help with, you can create new questions for them here.

  • I need heed help for Handle the JButton

    hi, guys
    I am writing a small program
    It has name and number field.

    are you trying to load a multi line textfile int a JTextField? If you try to load this in a while loop as you read the file, it will zoom through the file, and you will probably only see the last line of the file (or nothing if the last line is blank) in the jtextfield. Consider using a JTextArea or some other component that can hold multiple lines. Also your file reading method calls look wrong to me. You appear to read a line, then continually check if that one read line is null, and if not do a while loop, that looks to loop forever. Look at the java I/O examples for how to do this right.
    Good luck
