Problem statement:
We have two session beans in two different EJB modules deployed in Sun Java Application Server 9.1.
The name of the session bean are as follows:
Source Session Bean EJB Module contains:
1>SourceSessionBean
2>SourceSessionBeanRemote
3>SourceSessionBeanLocal
Target Session Bean EJB Module contains:
1>TargetSession Bean
2>TargetSession BeanRemote
3>TargetSession BeanLocal
We are trying to access the Target Session bean through it's Remote Interface from the Source Session Bean using dependency injection with the annotation as follows:
@EJB TargetSessionBeanRemote objTargetSessionBeanRemote;
Deployment:
We have deployed the target session bean first & then tried to deploy the source session bean. That produced the following error:
