NameNotFoundException when calling a EJB in Weblogic 10.3

Question

I have a EJB defined as this: ``` package com.foo; @Stateless (mappedName="HelloWorld") public class HelloWorldBean implements HelloWorld, HelloWorldLocal .... ``` When it's deployed to Weblogic (WL), it gets the name myBean. I'm not sure if this is important. I try to call the bean with this code: ``` Hashtable ht = new Hashtable(); ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory"); ht.put(Context.PROVIDER_URL, "t3://localhost:7001"); ic = new InitialContext(ht); tp = (HelloWorld) ic.lookup("HelloWorld#com.foo.HelloWorldBean"); ``` Anyone know why I get the following error? ``` javax.naming.NameNotFoundException: While trying to lookup 'HelloWorld#com.foo.HelloWorldBean' didn't find subcontext 'HelloWorld#com'. Resolved '' [Root exception is javax.naming.NameNotFoundException: While trying to lookup 'HelloWorld#com.foo.HelloWorldBean' didn't find subcontext 'HelloWorld#com'. Resolved '']; remaining name 'HelloWorld#com/foo/HelloWorldBean' ```

Accepted Answer

To lookup a Remote Interface of a Session Bean with multiple Remote Business interfaces (e.g.`com.acme.FooBusiness1`, `com.acme.FooBusiness2`), you need to lookup a name derived from the combination of the target ejb's global JNDI name (the `mappedName()` in `@Stateless`) and the specific Remote Business Interface, separated by a "#":

```
InitialContext ic = new InitialContext();
FooBusiness1 bean1 = (FooBusiness1) ic.lookup("FooEJB#com.acme.FooBusiness1");
FooBusiness2 bean2 = (FooBusiness2) ic.lookup("FooEJB#com.acme.FooBusiness2");
```

In the typical case of a bean only having one Remote Business Interface, this fully-qualified form is not needed. In that case, the bean's JNDI name can be used directly :

```
FooBusiness bean = (FooBusiness) ic.lookup("FooEJB");
```

That was the theoretical part. Now the practice. In your case, from what I can see, you are accessing the EJB from Weblogic so I'd rather use the no-arg `InitialContext()` constructor (and use a `jndi.properties` configuration file for other environments) but this is just a side note. Then, you should look up `com.foo.HelloWorld`, the Remote Interface, not `com.foo.HelloWorldBean`, the implementation:

```
InitialContext ic = new InitialContext();
(HelloWorld) ic.lookup("HelloWorld#com.foo.HelloWorld");
```

And if your bean has only one Remote Business Interface, this should work:

```
(HelloWorld) ic.lookup("HelloWorld");
```
