Would you want to give this to someone from GSoC? This could actually be a pretty sweet project.

Hells yeah. that's the right attitude :-). cheers, Sergey ----- Original Message ----- From: "Tong, Gary (IDEAS)" <gary.t...@morganstanley.com> To: <dev@cxf.apache.org> Sent: Tuesday, April 07, 2009 8:53 AM Subject: RE: JSON in CXF Hi Sergey, If you give me until next week I should be able to package something together and send it to you. Alternatively, this would be a great project for GSoC, if it's not too late to submit projects. Rewriting Sun libraries? Working with JSON? Hells yeah.

I was about to do it myself but given my JSON experience (not great so to say) I thought I would ping you first :-) we can introduce a new package, org.apache.cxf.jaxrs.providers.json, or org.apache.cxf.jaxrs.ext.json, and add these annotations there, and then rely on the fact Jettison ships JSonObject/etc... cheers, Sergey >> >> This will produce this JSON: >> >> {success: true, msg: "Test Message", errors: ["a", "b"]} >> >> And this XML: >> >> <response success="true"><msg>Test >> Message</msg><errors><error>a</error><error>b</error></errors></respo >> nse> >> >> Since this was written only for personal use, it's a fair bit aways >> from being a full-featured library.
