public String logic1(rsp.ejbbm.ex.studVO s) {
          rsp.ejbbm.student.studentRemote r=null;
          String id = null;
          try {
System.out.println("sdfsdfsdfs");
          Object obj = ctx.lookup("ejb/student");
          System.out.println("Lookup Succeded ");
          System.out.println("Object value" +obj.toString());
/// HERE I GOT THE ERRO I COULDn'T Locate IT
EJBHome obj1 =(EJBHome)javax.rmi.PortableRemoteObject.narrow(obj,rsp.ejbbm.student.studentHome.class);
          System.out.println("Object value" +obj1.toString());
          rsp.ejbbm.student.studentHome home=(rsp.ejbbm.student.studentHome)obj1;
          //studentHome hom=(studentHome)ctx.lookup("ejb/student");
     System.out.println("Object value" +obj.toString() );
     System.out.println("Lookup Converted ");
          home.create(s.getRollno(),s.getName());
          System.out.println("student Record isInserted in Oracle ");
          r= (rsp.ejbbm.student.studentRemote) home.findByPrimaryKey(s.getRollno());
          System.out.println("Student 5555 Name is "+ r.getName());
          id = r.getName();
          catch(Exception e ){
          System.out.println(e.toString());}
