    EJB with Inprise


    Hello,

    i am a beginner for EJB Programming. I work with the EJB book from O'Reilly
    (very good).
    i write a little EJB with JBuilder (HelloWorld) and deploy it to the EJB
    Server Inprise without problems.
    In the next step i create with a wizard from JBuilder a test Client.
    almost if i debug the Client i get an Exception at the follow statement.

    the statement
    -------------
    helloWorldHome = (HelloWorldHome) PortableRemoteObject.narrow(ref, HelloWorldHome.class);

    the error
    ---------
    javax.naming.NameNotFoundException. Root exception is org.omg.CosNaming.NamingContextPackage.NotFound

    at org.omg.CosNaming.NamingContextPackage.NotFoundHelper.read(NotFoundHelper.java:34)

    at org.omg.CosNaming.NamingContextPackage.NotFoundHelper.extract(NotFoundHelper.java:50)

    at org.omg.CosNaming._NamingContextStub.resolve(_NamingContextStub.java:161)

    at com.sun.jndi.cosnaming.CNCtx.callResolve(CNCtx.java:324)

    at com.sun.jndi.cosnaming.CNCtx.lookup(CNCtx.java:373)

    at com.sun.jndi.cosnaming.CNCtx.lookup(CNCtx.java:351)

    at javax.naming.InitialContext.lookup(InitialContext.java:350)

    at javax.naming.InitialContext.lookup(InitialContext.java:350)

    at ejb1.HelloWorldBeanTestClient4.<init>(HelloWorldBeanTestClient4.java:19)

    at ejb1.HelloWorldBeanTestClient4.main(HelloWorldBeanTestClient4.java:42)



    I hope someone can help me

    Re: EJB with Inprise


    See what the name of your home object is. Check what the context naming is
    the line before this.
    eg.... Object ref = ctx.lookup("test.ejb.testLaunch");

    This is the line that would throw that exception.
