Hi--
I'm trying to configure jboss 3.0.4 w/tomcat4.1.12 for CMR for two tables in
our Oracle DB. I use xdoclet1.1.2 to generate the interface and bean
classes. I have managed CMP for both tables that I'm using, but am having
some trouble joining the two for CMR.
Apologies in advance for the deluge of xml and code you are about to see...
:)
The bean is deployed just fine, but the following error stack is generated
when I try to use the one bean to get the many bean via a Collection:
eBillClient caught an unexpected exception!

Here is the customer bean w/xdoclet tags:
package com.uscc.account.entity;
// uscc ejb imports

// util imports
import java.util.Collection;
/**

* schema="account"
*
* @ejb:home extends="javax.ejb.EJBHome"

*
* @ejb:pk extends="java.lang.Object"
*
* @ejb:transaction type="Required"
*
* // begin jboss xdoclet attributes

*/
public abstract class customerBean extends defaultEntityBean
{
/**

*/
public abstract Collection getSubscribers();
/**

*/
public abstract void setSubscribers(Collection subscribers);
}
Here is the subscriber class:
package com.uscc.account.entity;

public abstract String getContactTN();

*/
public abstract customerBean getCustomer();
/**
* @ejb:interface-method view="remote"
*/
public abstract void
setCustomer(com.uscc.account.interfaces.customerBean theCustomer);
}
Can someone eyeball something that is hosed up. I haven't been able to find
anything on the web regarding this type of exception, so I'm stumped.
Thanks!
