Hello,
I'm publishing a session bean a WebService and it works just fine.
The problem is that some methods returns or receives instances of an EntityBean. The problem arises when I add some mapped relations that involve such a bean.
In my "Hello World" example I'm using the WS to retrieve, create and modify UserBean (login / password). WHen I add a many2one relation "friend" that maps users to users WebService stop working.

any idea if there is any limitation on the type of WS parameters?

thanks
Mario
