The client generated using JAXBRI bindings creates invalid request XML with version 1.6.1. The same code works with Axis 2 1.5.1 using JAXBRI bindings and Axis 2 1.6.1 using ADB bindings.
This problem seems to impact several clients for various Web Services. All clients were working fine with Axis 2 1.5.1.
I will attach WSDL, test client, and code generation commands to this ticket.
