Hi,
I'm developing a on-demand web application that use mutiple datasources. The EJB part of the app have this structure:
- Base classes (Entity - EmbeddableSuperclasses - and sessions)
@EmbeddableSuperclass
package app.ejb;
@Table(name="COM_CUSTOMERS")
public class CustomerEntity implements Serializable {
- A standard (mandatory) implementation of base entity beans (std.par)
package app.std.ejb;
@Entity
public class CustomerEntity extends app.ejb.CustomerEntity {
- Multiple (optional) customized implementation of base entity beans (cust1.par, cust2.par)
package app.cust1.ejb.;
@Entity
public class CustomerEntity extends app.ejb.CustomerEntity {
Now, every customized implementation need to access to own datasource (specified in persistence.xml of PARs), using both own and standard entity bean implementations (the correct class is loaded through a custom ClassLoader that use the current context).
Note that the std.par NOT need to have a reference to a datasource.
The problem is when I package the application. If I include std.par (with jar-file) in customized PARs, JBoss tell me that I have already registered entity beans:
AnnotationException: Use of the same entity name twice: CustomerEntity
Please you can tell me a solution to this problem?
