@Service concurrency

[vtatai]

Does anybody know if for @Service beans concurrency is handled like session beans (single thread), or it should be done manually?

Thanks,

As per JBoss Specifications org.jboss.annotation.ejb.Service annotated beans have Singleton behaviour, so only a single instance of the bean exists in the server.

Further they can be exposed similar to EJBs with @Remote and @Local which means the calling client will be executing the same instance over multiple calls, so concurrency issues have to be handled manually.

I am Still wondering about its behaviour when it is also annotated with @org.jboss.annotation.ejb.Clustered
:-)
