CMP 2.0 in JBoss 3.0
I'm trying to deploy an entity bean with CMP 2.0 in JBoss 3.0.0alpha (which I downloaded this week). The following warnings show up when I deploy:
[10:54:34,563,ContainerFactory]
Bean : OrderEJB
Section: 9.2.2
Warning: The entity bean class must not be defined as abstract.
[10:54:34,565,ContainerFactory]
Bean : OrderEJB
Section: 9.2.2
Warning: The entity bean class must define a public constructor that takes no arguments.
[10:54:34,568,ContainerFactory]
Bean : OrderEJB
Section: 9.4.7.1
Warning: The primkey-field element must name a public field in the bean implementation class.
(I saw the other post on this, but I am using JBoss 3.0.) The bean deploys, but when I try to access it with a session bean, I get an InstantiationException:
[11:05:31,866,LogInterceptor] TransactionRolledbackException, causedBy:
java.rmi.ServerException: Could not instantiate bean; nested exception is:

The classes couldn't be much simpler:
<CODE>
------------- Home ------------------
package mypkg.order;
import javax.ejb.*;
public interface LocalOrderHome extends EJBLocalHome {
public LocalOrder create(Integer oid) throws CreateException;
public LocalOrder findByPrimaryKey(Integer key) throws FinderException;
}
------------- Local ----------------package mypkg.order;
import javax.ejb.*;
public interface LocalOrder extends EJBLocalObject {
public Integer getOrderId();
}
-------------- Bean ----------------
package mypkg.order;
import javax.ejb.*;
public abstract class OrderBean implements EntityBean {
private EntityContext context;
public abstract Integer getOrderId();
public abstract void setOrderId(Integer oid);
public Integer ejbCreate(Integer oid) throws CreateException {
setOrderId(oid);
return null;
}
publid void ejbPostCreate(Integer oid) throws CreateException { }
public void setEntityContext(EntityContext ec) {
context = ec;
}
public void unsetEntityContext() {
context = null;
}
public void ejbActivate() { }
public void ejbPassivate() { }
public void ejbLoad() { }
public void ejbRemove() { }
public void ejbStore() { }
}
</CODE>
The deployment descriptor is as EJB 2.0 as I know how to make it:

Any help will score you some major karma, to be sure.
