Groovy Jabber-RPC

Jabber-RPC allows you to make XML-RPC calls using the Jabber protocol. Groovy has a Jabber-RPC implementation which allows you to create a local Jabber-RPC server and to make calls on remote Jabber-RPC servers. Jabber servers are widely available and very easy to set up and run. The Google GTalk service uses Jabber and the Groovy Jabber-RPC package works over GTalk.
We use the excellent Smack Jabber library from Jive Software to handle the protocol details.

The Server

It's really easy to set up a server which provides a set of remotely callable functions.

1. Create a server object
2. Add some methods
3. Start the server
4. You're done!

The Client

It's pretty easy to make the remote calls too

1. Create a proxy object to represent the remote server
2. Call the remote method via the proxy
3. As long as myClientId@example.org and myServerId@gexample.org are buddies then the call will be made and the result returned
