Fail to lookup the local EJB by JNDI in Managed Server

Question

Hi all,
I currently in a deep problem, and can't figure out the cause of it. It just annoying me for week.
In my app, I have binded to the local ejb to JNDI (let's say "ejb/CustomerLocal"), then the client lookup the Local EJB by the following code.
localIc = new InitialContext();
home = (EJBLocalHome)localIc.lookup("ejb/CustomerLocal");
It works well as I do development in the Domain Admin Server. However, when I do the System Integration Test and deploy my app to the managed server, the app fail. It just can't do the Local EJB lookup. Following is the exception.
javax.naming.NameNotFoundException: Unable to resolve 'ejb/CustomerLocal' Resolved ejb[Root exc
eption is javax.naming.NameNotFoundException: Unable to resolve 'ejb.CustomerLocal' Resolved ejb
]; remaining name CustomerLocal'
Does anybody know the cause of it and have solution?
Thanks a lot

Hi,
Just now I replicated the same problem what you are facing. I created one managed server. When I deployed my ejb to admin server I did not get any problem. But when I deploy the same into my managed server I got Naming Exception. Because I did n/t specify Context.PROVIDER_URL. A provider URL contains bootstrap server information that the initial context factory can use to obtain an initial context. So when you deploy EJB on another server, you have to get the Naming service from that server. Hence provider URL must pointing to that server. So I included following statements before lookup my ejb in managed server.
Properties p=new Properties ();
p.put (Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
p.put (Context.PROVIDER_URL,"t3://localhost: 7003");
Context ctx=new InitialContext (p);
FacadeHome home=(FacadeHome) ctx.lookup ("ejb/CustomerLocal");
In my case managed server port number is 7003. Now onwards managed server (Port number 7003) will provide ‘Naming Service’, not by admin server (port number 7001), which is default.
Note: Context.PROVIDER_URL— specifies the URL of the WebLogic Server that provides the name service. The default is t3://localhost: 7001. When you are not specified it will assume that POVIDER_URL is t3://localhost: 7001 this is nothing but your admin server in your case. However, a JNDI client may need to access a name space other than the one identified in its environment. In this case, it is necessary to explicitly set the java.naming.provider.url (provider URL) property used by the InitialContext constructor.
I hope it helps.
