Hi Guys,

Can someone explain what is the difference between JTA and resource-local Entity Manager, Why CMT doesnt support resource-local

I expect a clear description than JPA spec 5.5

Regards
Cham

"resource-local Entity Manager" are used outside to the Java EE container. As an example if we are dealing with a swing application, JTA is not a possibility. So resource-local transactions are used in this case. So implementation of EntitTransaction interface is required.
