Here is an update: I was able to inject the PersistenceContext into my session bean by retrieving the LocalInterface class from the InitialContext within my web service java class. | SampleClass sc = null; | InitialContext ic = new InitialContext(); | sc = (ISampleClass)ic.lookup("MyEar/SampleClass/local"); | I tried injecting the EJB at the class level - but that was always null. | @EJB (mappedName="MyEar/SampleClass/local") | SampleClass sc; | I also tried just setting the mapped name to: SampleClass, MyEar/SampleClass and a bunch of other things - but none of them worked. Is this the optimal solution to get my web service an instance of my stateless session bean from the container?
