Hi All,

I have a use case where the application has to complete a global transaction by 
calling various components. Each component maintains its own 
EnityManagerFactory and persists data [using a JPA provider]. 

Would it be possible to commit/rollback transactions globally on the multiple 
EntityManagers., i.e., if any one component's EM fails would the application 
[assuming running on a managed environment] be able to rollback other EM 
operations that have been performed on the database so far?.

I was looking into the JBoss Trailblazer - it speaks of a single EntityManager 
using a session bean. 

Any reply would be appreciated.

Thanks
Karthik
