I am not able to lookup local session beans from within an EJB module in WebLogic 10.3.6.
In the following example I could use injection, but in the actual product we will need to access local session beans from non-managed objects, so this is for demonstration of the problem. I also know it'll work with a remote interface, but why since I should be able to do it locally.
@Local
public interface MyBeanLocal {
public void foo();
}
@Stateless(name = "MyBean")
public class MyBean implements MyBeanLocal {
@Override
public void foo() {
System.out.println("Foo");
}
}
Here the client tries to look up the local session bean. This very same code seems to work in other application servers, but not in WebLogic.
@Stateless
public class CustomerInbound implements CustomerInboundLocal {
@Override
public void someOperation() throws Exception {
try {
// Exception is thrown here when looking up the object
MyBeanLocal testLocal = (MyBeanLocal)
new InitialContext().lookup("java:comp/env/MyBean");
testLocal.foo();
} catch (Exception e) {
e.printStackTrace();
throw e;
}
}
}
Exception:

You must declare a reference to the EJB in order to look it up from java:comp. You can either use the @EJB annotation (with or without injection, see What does the @EJB annotation do?), or you can declare the reference in web.xml using <ejb-ref>.
Otherwise, if you were using a newer version of WebLogic that supported EE 6, you could use the portable java:global, java:app, or java:module namespaces in order to look up the EJB directly, but since WebLogic 10.3.6 only supports EE 5, you would need to use the configured binding name of the EJB.
