EJB with Inprise

[Orhan]

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

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.
