      Hello,

      I'm developing app in EJB3

      I've made remote inteface with method returning one of Entity bean.

      After implement in Stateless bean, and try to use it from client through jndi I get error on client side:

      What can be wrong?


      When I use simple type like int, boolean it's works.
