Exception in ContainerManaged EJB

Question

Hai everybody,
I have written a ContaianerManagedEntity Bean. Iam trying to insert data into Oracle8i Database using J2EE server.
There is no problem with database. It is calling ejbCreate() method and it is executing till the last statement of ejbCreate() method.But after ejbCreate() it is not executing ejbPostCreate() method.
The Exception Iam getting is:
at com.sun.corba.ee.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:296)
     at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)
     at com.sun.enterprise.iiop.POAProtocolMgr.createReference(POAProtocolMgr.java:313)
     at com.sun.ejb.containers.EntityContainer.internalGetEJBObject(EntityContainer.java:796)
     at com.sun.ejb.containers.EntityContainer.getEJBObject(EntityContainer.java:167)
The complete Exception is about 7000(seven thousand) lines. The above are only first 3 lines.
I could not able to trace where the exact problem is. somebody please help me..
This is my ejbCreate and ejbPostCreate() code:
public void ejbCreate(String companyID,String name,String city,String state,String pin,String address)
          throws CreateException {
          System.out.println("ejbCreate2 Called");
          if(companyID==null) {
               throw new CreateException("Product id is requiered");
          this.companyID=companyID;
          this.name=name;
          this.city=city;
          this.state=state;
          this.pin=pin;
          this.address=address;
          System.out.println("record inserted successfully");
//          return null;
public void ejbPostCreate(String companyID,String name,String city,String state,String pin,String address)
          throws RemoteException
          {System.out.println("ejbPostCreate2 Called");  }
Iam using PrimaryKey Class.
primary key field :companyID
Thank you,

ok...check ur client whether it has the following code.....if its a class cast exception then,may be this is the problem...
objref = initial.lookup("path...");
YourHome yourHome =
(YourHome)PortableRemoteObject.narrow(objref,
YourHome.class);
are u casting the object returned from the PortableRemoteObject to your home object ?????
