| It tests the security feature of JavaEE service engine. JavaEE SE is used on consumer as well as on the provider side. |
| An EJB webservice is invoked by a servlet that requires authentication. This webservice method returns the caller principal associated with the invocation. |
| A temporary file user is created in this test. |
| |
| Here is the invocation flow- |
| |
| 1. Standalone client invokes the servlet after passing proper user credential. |
| 2. Apserver invokes the servlet with a Principal. |
| 3. Servlet calls the EJB webservice. |
| 4. EJB webservice returns the caller principal associated with the EJBContext. |
| 5. Servlet sends the returned value of EJB webservice in the response. |
| 6. Client checks whether the returned principal matches with the one it was invoked. |
