What is the equivalent of an EJB 3.0 Session Bean in Spring?

Question

Is it as simple as creating a POJO with @Transactional methods?

Answer 1

Yes, spring beans are pojos. You have to declare it in applicationCotnext.xml or annotate it with @Service.

Answer 2

In Spring you create it as normal bean and you specify session scope or @Scope annotation.

Answer 3

Spring beans (i.e. properly declared) annotated with @Transactional are comparable to Local Session Beans. For Remote Session Beans, you would have to add some remoting to your Spring configuration (RMI, Web Services, Hessian, Burlap, HTTP invokers). But Spring remoting does not support out of the box security and transaction propagation (unlike EJBs).
