    problem returning Local interface to entity beans when a rem

    luis valenzuela Newbie

      Anyone have any idea what is happening here??

      I have some entity beans that have local and remote interfaces, they are referenced by a session bean and I have placed the local refs in the deployment desciptor like so;

      <ejb-local-ref>
      <ejb-ref-name>ejb/FacultyLocalEJB</ejb-ref-name>
      <ejb-ref-type>Entity</ejb-ref-type>
      <local-home>com.uni.faculty.FacultyHomeLocal</local-home>
      com.uni.faculty.FacultyLocal
      <ejb-link>FacultyEJB</ejb-link>
      </ejb-local-ref>

      <ejb-local-ref>
      <ejb-ref-name>ejb/StudentLocalEJB</ejb-ref-name>
      <ejb-ref-type>Entity</ejb-ref-type>
      <local-home>com.uni.student.StudentHomeLocal</local-home>
      com.uni.student.StudentLocal
      <ejb-link>StudentEJB</ejb-link>
      </ejb-local-ref>

      <ejb-local-ref>
      <ejb-ref-name>ejb/SchoolLocalEJB</ejb-ref-name>
      <ejb-ref-type>Entity</ejb-ref-type>
      <local-home>com.uni.school.SchoolHomeLocal</local-home>
      com.uni.school.SchoolLocal
      <ejb-link>SchoolEJB</ejb-link>
      </ejb-local-ref>

      <ejb-local-ref>
      <ejb-ref-name>ejb/AddressLocalEJB</ejb-ref-name>
      <ejb-ref-type>Entity</ejb-ref-type>
      <local-home>com.uni.address.AddressHomeLocal</local-home>
      com.uni.address.AddressLocal
      <ejb-link>AddressEJB</ejb-link>
      </ejb-local-ref>

      But when I try to use them like;

      InitialContext jndiContext = new InitialContext();
      Object obj = jndiContext.lookup("java:comp/env/ejb/FacultyLocalEJB");
      FacultyHomeLocal facultyHome = (FacultyHomeLocal)obj;

      obj = jndiContext.lookup("java:comp/env/ejb/StudentLocalEJB");
      StudentHomeLocal studentHome = (StudentHomeLocal)obj;

      obj = jndiContext.lookup("java:comp/env/ejb/SchoolLocalEJB");
      SchoolHomeLocal schoolHome = (SchoolHomeLocal)obj;

      obj = jndiContext.lookup("java:comp/env/ejb/AddressLocalEJB");
      AddressHomeLocal addressHome = (AddressHomeLocal)obj;


      I recieve the following exception;
      java.lang.ClassCastException: $Proxy364
      at com.uni.dataFiller.DataFillerBean.initialize(DataFillerBean.java:36)

      This is because remote interfaces are being returned when Local one should be instead. To make things more irritating I only get the exception with some of the beans that have remote and Local interfaces and not with others and all works fine if I remove the remote interfaces to my entity beans.

      Cheers in advance
