Problem calling entity bean from session bean using sun one app server

Question

Hi,
I am getting the following exception while calling entity bean(bmp) from stateless session(cmp)bean.
SEVERE: IOP5012: Some runtime exception ocurred in IIOP: [javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: Unable to create reference org.omg.CORBA.OBJ_ADAPTER: vmcid: SUN minor code: 1015 completed: No]
SEVERE: IOP5013: Unable to create reference: [org.omg.CORBA.OBJ_ADAPTER: vmcid: SUN minor code: 1015 completed: No]
SEVERE: EJB5029: Exception getting ejb context : [CustomerEJB]

WARNING: CORE3283: stderr:
My primary key implementation is
public class CustomerEJBKey implements java.io.Serializable {
static final long serialVersionUID = 3206093459760846163L;
public String customerId;
public DBConfigBean dbConfigBean;
* Creates an empty key for Entity Bean: CustomerEJB
/*public CustomerEJBKey() {
public CustomerEJBKey(String customerId,DBConfigBean dbConfigBean){
this.customerId = customerId;
this.dbConfigBean = dbConfigBean;
public String getCustomer(){
return customerId;
public DBConfigBean getDBConfigBean(){
return dbConfigBean;
* Returns true if both keys are equal.
public boolean equals(Object key) {
if(key instanceof CustomerEJBKey)
return this.customerId.equals(((CustomerEJBKey)key).customerId) &&
this.dbConfigBean.equals(((CustomerEJBKey)key).dbConfigBean);
else
return false;
* Returns the hash code for the key.
public int hashCode() {
return customerId.hashCode() + dbConfigBean.hashCode();
and entity bean method invocation is,
homeFactory = EJBHomeFactory.getInstance();
home = (CustomerEJBHome) homeFactory.lookup(CustomerEJBHome.class);
remote = (CustomerEJB) PortableRemoteObject.narrow( home.findByPrimaryKey(new CustomerEJBKey(customerId,dbBean)), CustomerEJB.class);
This works fine in Websphere and JBoss. Do you have any idea why I am getting this exception?
Appreciate your response.
Regards,
Sankar.

My suggestion is to put some System.out.println() statements and see if the output helps in any way in debugging. I can't think of anything on the top of my head although I have been working lightly on SunONE.
By the way, you referred the stateless bean as CMP. Just wanted to tell you that you are wrong. The terms CMP and BMP refer to persistence, which is applied to Database tables and not to stateless/stateful session beans which are written for some specific purpose independent of underlying database.
