Great both of those content types worked. Thanks!!!
Now, I am trying to build a service that would handle JSON data. Need to receive data in JSON format and return response in JSON format. I have looked at the article referenced earlier: http://wso2.org/library/768 However, I am unclear on what aspects do I need to implement on the service side. Can I have a POJO-based service that accepts JSON and return JSON? I do see samples for JSON clients. I would appreciate if someone could point me to a JSON service example. (Not interested in SOAP-based services. REST is preferred.) Thank you very much.
