Thanks for the information Anne. Now I get a better idea of what JSR-109 is. It seems like a pretty useful specification.
I understand that JSR-109 doesn't force you to use EJBs, you can have a servlet implementation or an EJB implementation in a JSR-109 web service, which is great. But I still get the impression that it forces you to use a procedure-oriented model for building web services. Is it possible to build document-oriented web services using JSR-109?
Thanks,
Mete
