Axis 1 Response always in Json

Hello,

i have a problem with a web service based on axis 1 with rpc binding. When i use soapUI i get the response as xml, when i use the same wsdl and generate with maven axis and wsdl2java the client stub, i get the response as json format which i can not use.

Any idea to switch to xml as response? how does this soapUi?

with regards
