Jersey method selection by query parameters

Question

I need to implement a webservice that uses the first query parameter to identify the operation, i.e. the client call would be something like: http://localhost:8080/ws/oper

Answer 1

I think method selection is based on the non parameter part of the URI. Can't you design this in a way the client invoke http://localhost:8080/ws/operation/info and http://localhost:8080/ws/operation/create?name=something instead?

That would be easy to achieve:

@Path("/operation")
public class Operation {

    @GET 
    @Path("info")
    public String info() {
        return "info";
    }

    @GET 
    @Path("create")
    public String create(@QueryParam("name") String name) {
        return "create";
    }
}
