Subject Re: ROP [Was: [jira] [Commented] (CAY-2038) Hessian serialization error when using JSR-310 Date types with ROP]

Though I guess the main motivation for Java ROP now is the ability to run code both on the
client and on the server, right? 

If so, let's focus on the data protocol, which can then be used either with the current ROP
or a stripped down proxy.
