java.util.Date in response for RPCMessageReceiver

James Taylor Sun, 04 Jun 2006 22:21:01 -0700

Hello,

I'm trying to invoke an Axis2 web service that returns a java.util.Date in its response, but am getting the exception below. I'm using a snapshot from a few days back. I've also included my sample web service implementation. Is this supposed to work?

Thanks!

James
