In practice, we should make simple for users to generate a wsdl. What they are used to do today when the wsdl is not trivial : - write a java interface that is a copy of the SEI but with all attachment params replaced with String params. - generate the wsdl with wtools from this interface - make simple changes to wsdl to replace string type by what is required for wstools to detect attachments - test if client side is correctly generated from this wsdl - test if the server side is working with this stubs calls View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4004500#...
