    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public void newUser(
            @FormParam("uname") String uname,
            @FormParam("password") String password,

Answer 1

Use the @Path and @PathParam annotations:

@Path("/user/{uname}")
@PUT
@Consumes("text/plain")
public void putUser(@PathParam("uname") String uname, String password) {
  // ..
}

If you PUT to /user/joe with a body of s3cret, then uname will be joe and password will be s3cret.

I use PUT because the URL you want to use implies that the username is set by the client. /user is the collection resource of all users.

Edit: Since this method will change the server state by creating a new user, PUT or POST must be used. GET must not change the server state.
