    Problem accessing EJB Statefull Session Bean

    Carlos Casovsky Newbie

      Hi guys,
              I'm having a problem, I think it may be something that I'm missing, but I honestly don't know what it is. I have a Statefull Session Bean, bound to the Application Scope as follows:


      @Name("cvManager")
      @Scope(ScopeType.APPLICATION)
      @Stateful
      @AutoCreate
      public class CommonValueManager implements Serializable, CommonValueCacheProvider



      then I'm trying to access this bean by either of this two methods:


      CommonValueCacheProvider cvManager;
                
      cvManager = ( (CommonValueCacheProvider) Component.getInstance("cvManager") );



      Or


      @In(required=false,create=true)
      private CommonValueCacheProvider cvManager;



      and I get the following exception, at least in the second case:


      Caused by: org.jboss.seam.InstantiationException: Could not instantiate Seam component: cvManager
           at org.jboss.seam.Component.newInstance(Component.java:2106)

      my component configuration has the following parameters, in case the JNDI name strikes you as odd:


      <core:init debug="true" jndi-pattern="seamTrial\#{ejbName}\local" precedence="100"/>



      Any help will be great,


      thanks
