Hi all,
A few months ago in the EJB 3.2 EG ML we talked about aligning BV in EJBs.
We've also exchanged a few emails with Emmanuel Bernard (CCed) about BV
aligment in other specification. As a developer I expect BV method level
validation to work in every EE specification. What do you think ? If it's
the case, I would expect this to work :
*_at_WebServlet*
public class MyServlet {
public void doGet(*_at_NotNull* HttpServletRequest req, @NotNull
HttpServletResponse resp) {}
}
or
*_at_WebService*
public class MyWS {
@WebMethod
*_at_NotNull*
public String methodA(@WebParam(name = "myParam") *_at_NotNull* String s )
}
So that means a JAX-WS update will have to be made (JAX-WS 2.3 ?). With
WebServices that would also mean that BV will be integrated with JAXB (but
I think it's planned, Emmanuel correct me if I'm wrong).
What do you think ?
