Sending a user defined object with JAXRPC??

[cig]

Hi I am trying to invoke a JAXRPC service which accepts a User Defined Object using the Spring JAXRPC client. It works great for standard types but breaks with a user defined type. Does anybody have any ideas?
Below is the exception raised....

Axis cannot deal with user defined objects without a declared serializer in your wsdd service description.

http://ws.apache.org/axis/java/user-...ml#DataMapping
Good stuff there

Strings, bools, ints and the like are fine, but user defined stuff requires serializers. If you working with a bean, the beanMapping is the way to go.

Thanks.
I found an example in the petstore example. Got it working.
