问题
I have the following situation: My applications needs to dynamically connect to multiple databases, so after a lot of search I think the best option is to do create multiple EntityManagers and decide at runtime which one to use.
Here is the code:
public class GenericDao {
@PersistenceContext(unitName = "db1")
protected EntityManager em1;
@PersistenceContext(unitName = "db2")
protected EntityManager em2;
@PersistenceContext(unitName = "db3")
protected EntityManager em3;
}
This way I can connect to all databases, and still have my transactions managed by the container.
The problem is when one of the connections fails, my application don't even deploy in this case, and a get the following exception:

Does anyone knows if it is possible to deploy the application even if the connection fails? If I don't use the @PersistenceContext it all works fine, but I really want to have my transactions managed by the container.
I'm using Glassfish 3.1.2.2, JPA2, EclipseLink and EJB3.
