Good morning,

first of all thanks for your replies. I'am using JBoss 5.1 and I tried using the annotation @EJB(mappedName="MyBean/remote") like Daniel suggested. The deployment works fine, but when I try to use a service-method the following exception occur:


08:26:45,500 ERROR [InjectionException] Cannot inject field annotated with @EJB annotation: de.hd.bean.MyBean de.hd.myservice.MyServiceImpl.psr
