    EJB3.0 and Web container - this should be easy, but...

    kimbaltrue Newbie

      I have an EAR file that contains an EJB 3.0 Stateless bean, a Persistence Unit, (currently a shard JAR), and a WAR file.

      The persistence unit loads, the EJB 3.0 bean loads, and references both the persistence unit and the shared jar.

      The WAR file will not load as long as it tries to access the EJB bean.

      Here is my Application file

      <?xml version="1.0" encoding="utf-8"?>
      <application xmlns:ns0="http://www.w3.org/2001/XMLSchema-instance" ns0:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd" version="1.4" xmlns="http://java.sun.com/xml/ns/j2ee">
      <display-name>athenaeum</display-name>
      <module>
      <ejb>athenaeumEJB.jar</ejb>
      </module>
      <module>
      <java>athenaeumModel.jar</java>
      </module>
      <module>
      <java>athenaeumShare.jar</java>
      </module>
      <module>
      <web>
      <web-uri>athenaeum.war</web-uri>
      <context-root>/athenaeum</context-root>
      </web>
      </module>
      </application>


      Here is my bean declaration

      @Stateless
      @Remote(org.ccf.athenaeum.ejb.Collection.class)
      @Local(org.ccf.athenaeum.ejb.Collection.class)
      @TransactionManagement(TransactionManagementType.BEAN)
      @Interceptors(org.ccf.service.ServiceMetrics.class)
      public class CollectionBean extends ServiceSupport implements Collection


      I have an application exception

      @ApplicationException
      public class ServiceException
       extends Exception



      In the WAR file I have a faces bean that attempts to access the EJB.

       Collection result = null;
      
       InitialContext context = new InitialContext();
       result = (Collection)context.lookup("athenaeum/CollectionBean/local");
      
       return result;
      


      At first I didn't have the shared library. I had all the EJB code and interface in the EJB Jar file, but as soon as I put a reference to the bean in the Faces code I got a NoClassDefFoundException - classic right.

      So, after trying serveral things including putting <ejb-ref> in the Web.xml, I finally tried splitting the EJB interface and the exception class into a shared JAR. The EJB jar loaded fine. The WAR failed.

      I even added a reference to the shared jar into the WAR file's manifest.

      Manifest-Version: 1.0
      Ant-Version: Apache Ant 1.6.5
      Created-By: 1.5.0_06-b05 (Sun Microsystems Inc.)
      Built-By: Owner
      Class-Path: athenaeumShare.jar
      


      I still get:

      What do I have to do the access an EJB 3.0 Bean from my JSF Bean?

        • 1. Re: EJB3.0 and Web container - this should be easy, but...
          kimbaltrue Newbie

          Here's an update:
          (P.S. I'm running JBOSS 4.2.0)

          After some searching and frustration, it occured to me that I could eliminate the shared object issue by copying the shared library into the
          lib directory. Yes, this is an act of desperation, but it did provide some relief. I'm now able to call the EJB successfully, and the Bean interface and ServiceException do not generate a NoClassDefFoundException.

          However - there's always a however - I can no longer hot deploy the application. If I try, the CPU goes to 100%, and everything hangs - more or less. Also, it's not very satisfying to have the EJB interface stored outside the EAR file.

          Is there any other solution outside of JBOSS 5? That is my eventual target,
          but it would be nice to get some decent testing in while 5 stabilizes.
