从不同的模块但相同的应用程序注入@EJB

Question

I have an application on a Weblogic Server. I have issues with injecting an EJB from my RESTWEBservice into my SOAPwebservice. This application have several modules. Only Three of them is important now.

The deployment looks like this:

Application

• API (JAR)
• SOAPWebService (WAR)
• RESTWebService(WAR)

Both Webservices have the API built into them. Here is the important part of the classes. My RestWebservice EJB I want to inject:

@Local(EJBSOAPinterface.class)
@Stateless(mappedName = "RESTCLASS", name="RESTCLASS")
public class RESTCLASS implements EJBSOAPinterface{...}

The interface in the API which both modules use:

@Local
public interface EJBSOAPinterface{....}

The SOAP webserviceModule who wants to inject the EJB

public SOAPCLASS {
@EJB(lookup="JNDINAME..")
EJBSOAPinterface ejb;
......}

I have tried to use both @Local and @Remote on both interface and the EJB. it doesn't work.

I have tried this to inject the EJB as well

public SOAPCLASS{
@EJB(name="RESTCLASS")
EJBSOAPinterface ejb;
.....}

it doesn't work either. The problem is that my SOAPCLASS wont deploy because of that injection. I get different Exceptions depending on how I do it. But currently I get

java.lang.InstantiationException: Error creating bean with name: "....." ..... Dependency injection failure: can't find the bean definition about class interface "....."

I am kind of new to java.

UPDATE - SOLVED. I did put @Remote instead of @Local on the interface. And the same thing on the EJB itself. The JNDI name i had was correct (RESTCLASS#INTERFACEPACKETNAME.EJBSOAPINTERFACE).

The problem was that when i deploy the application on the WLServer i deployed the SOAPCLASS Before the RESTCLASS. Which means that it couldnt find any JNDI name yet. Because it wasnt built yet. I just changed the deploymentorder of those 2 and it worked instantly. Thanks!
