How correctly produce json by RESTFUL web service on Fuse ESB?

[nehal_sadek]

I'm using CXf and JSON on FUSE ESB, I implement a restful web service as the following:

RestFul Method:

@GET

@Path("/user")

@Produces(MediaType.APPLICATION_JSON)

public User handleGeUser() {

User user = new User();

return user;

}

bundle-context.xml

and I got this error "No message body writer has been found for response class User." when calling the my user rest service.

could any one advise?

I am very new to JAXRS with CXF (but have used Jersey a lot)

According to http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-Jettison "Default JSON provider relies on Jettison 1.3 and it expects the types it deals with to follow the same techniques as described above in the JAXB support section for them to be handled properly."

I think, at a bare minimum you need the @XmlRootElement on your User object.

If you don't fancy JAXB annotations, you could check out the JacksonJsonProvider:  http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-Jackson
