Never mind. I think I answered my own question.
I added the following to my root resource. This would allow me to chain
resources.
@Path("{cs}")
public CustomerResource getCustomerResource(@PathParam("cs") String
cs) {
return new CustomerResource(uriInfo, request, cs);
}
And in the CustomerResource, I have the following:
@POST
@Consumes("application/xml")
@Produces("application/xml")
public Customer addCustomer(Customer customer) {
URI uri = uriInfo.getAbsolutePath();
customer.setUri(uri.toString());
return customer;
}
Thanks!
