Java & Google Protocol Buffers: I need an example of how to use Google Protocol Buffers with client-server communication

Looking for the best example you guys know of.

The examples on the site are with files. But the library should be able to w开发者_运维知识库ork over a Java.net.ServerSocket, at least I hope.

You can certainly write protocol buffers to an OutputStream and read them from an InputStream. The Protocol Buffers project itself hasn't specified an RPC protocol, but third parties have done so. Alternatively, if you're simply interested in transmitting a message, you should be able to wrap that message in any protocol which allows you to either specify a byte array and retrieve it at the other end, or which gives you a stream-based API.

If you need an example using a specific RPC technique listed in the third party add-ons page, I suggest you look at the home of that particular project.
