difference between stateful session bean and stateless session bean.

[Jingyi Wang]

Can anybody tell me why "get a transaction reference, and call methods on it", "access another bean's methods" and "access a resource manager" are not availabe in ejbCreate (), ejbRemove()? ( But, in stateful bean, they are available. )

Thanks

Jingyi,

I think this post has a very good explanation for it:

Also you could search this forum for "meaningful transaction context or client security context" - should bring up several posts that you might find useful (the one specified above is one of them)
