    hi all,
    i already put j2ee.jar into the libraries and classpath before i run it. i am new to jdeveloper. so i want to make sure if my setting is correct or not:
    the library settings is under project propertise-->libraries and classpath-->classpath entries: there listed the libraries the application uses.
    if i am correct, then the j2ee.jar is in there already.

    thanks a lot

    it seems you are running application server in jdeveloper;i think go application server properties and add this jar file and then restart the app server in jdeveloper.

    actually it is  jboss-j2ee.jar should be placed  in jboss/default/lib folder

    if you are running jboss in jdevloper check this link.

    actually i know nothing about this project and no one knows about this project in my team. it is a very old project. in the functional specification, says j2sdk 1.4.2, j2ee 1.3.1, jboss 3.2.3, log 4j 1.2.8 are used to build this system.
    i only know how to run it. like what i said before, it is a desktopGUI project. it is installed on user's local machine and run by a batch file.
    now we have a bug which is java.lang.out of memory. and i guess that's because the heap size is not enough, so i tried
    java –Xms256M –Xmx512M -jar comtrac.jar
    but i still get that out of memory error. so i have to open this project and try to debug it in JDeveloper.
    honestly, i don't know  if i need JBoss or not.
    i am newbie to Java.

    doesn't sound like you need it

    sounds more like it needs profiling

    whats the error you're getting btw?

    we use this application to upload file and export it to a specified folder. it was working very well but suddenly failed when you upload the file even you use the one which was uploaded successfully.

    pls have a look at the img.

    GUIHelper is a static class file. the method of getAllocationEJBInterface is attched
        public static void getAllocationEJBInterface() throws Exception {
    
            AllocationManager session = null;
    
            
    
            try {
    
                /** Creates a JNDI naming context for
    
                 * location objects */
    
                Context context = new InitialContext(GUIHelper.getEnvironment());
    
                
    
                /** Asks the context to locate an object named "AllocationManager" and expects the
    
                 * object to implement the AllocationManagerHome interface
    
                 **/
    
                System.out.println("Prepare to call Session Bean AllocationManagerHome via Jboss ");
    
                AllocationManagerHome home = (AllocationManagerHome)PortableRemoteObject.narrow(context.lookup("commission/AllocationManager"), AllocationManagerHome.class);
    
                
    
                /** Asks the Home interface to create a new session bean */
    
                System.out.println("Create the Allocation Session Bean AllocationManager");
    
                session = (AllocationManager)home.create();
    
                
    
            }
    
            catch (NamingException ex) {
    
                throw new NamingException("Naming Exception occured when tried to get the commission/AllocationManager");
    
            }
    
            catch (RemoteException ex) {
    
                throw new RemoteException("Remote Exception occured when tried to get the commission/AllocationManager");
    
            }

    1. now i try to run it in JDeveloper. i show you the contents of run/debug/profile-->run configurations: default,
    to make sure the settings are correct. pls look at the attachment.

    2. as i met the error java.lang.NoClassDefFoundError: javax/ejb/EJBObject when i try to run it. so currently, i right click the Main.java to run it from there. it starts the application but i got database problem. when i try to search a product, it executes a sql and return to me by saying there is an invalid identifier xxx. BUT I checked the table, that field does exist. so i think it is a database connection problem.
    in my application folder META-INF--> oracle-ds.xml , it defines the database connection like the following:
    <datasources>
        <local-tx-datasource>
            <jndi-name>OracleDS2</jndi-name>
            <connection-url>jdbc:oracle:thin:@xx.xxx.x.xxx:xxxx:COMTRAC</connection-url>
           <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
            <user-name>xxx</user-name>
            <password>xxx</password>
           <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
    <min-pool-size>0</min-pool-size>
            <max-pool-size>80</max-pool-size>
            <blocking-timeout-millis>5000</blocking-timeout-millis>
            <idle-timeout-minutes>5</idle-timeout-minutes>
            <prepared-statement-cache-size>0</prepared-statement-cache-size>
        </local-tx-datasource>
    </datasources>

    i am wondering if i still need to define the database connection in application level or somewhere?

    thanks a lot

    starting to get beyond where I can help you without know a lot more about the application

    That run configuration looks like it relies on the jars manifest to locate dependant jars

    Re the database I don't know enough about how the database is being used to help with that
