Complete Code For Spring-StateLessSessionBean

[avalone]

Hi,

i have tried in another way and now it works probably just a misunderstanding from me, but no matters thanks for all.

Do you know how i can with a webapps see all ejb in a jndi and load them with the dependancy injection in Spring. Imagine you have a webapps that can find automatically all services of a type and load them because they all implements the same interface(something like plugins).

Thanks,

Avalone.

Hello all,

I see few examples on SPRING + EJBs and I would like to thank everybody for contributing exposing these code lines!

I want to expose my problem.

I have a classic five layers architecture application with a complete separation between web stuff and services (managers in appfuse) and DAOs + model.
I use Spring as web framework.
In my actions I use delegates who does JNDI lookup with a Locator to EJB stateless services (I don't use Spring for that).
Only Services + DAOs have SPRING implementation.
I obtain this kind of error even if application deployment seems good :

In fact, I wanted to know if I have to register SPRING application context in the client or this kind of implementation is possible.

Thanks all !

There is no reason why you can't use a service locator. EJBs implemented using Spring are still EJBs. There must be another issue.

It works!!! Thanks!!!
