How do I serialize a Java object such that it can be deserialized by pickle (Python)?

I'm using a Python service that uses pickled messages as part of its protoco开发者_开发问答l. I'd like to query this service from Java, but to do so, I need to pickle my message on the client (Java). Are there any implementations of pickle that run on the JVM (ideally with minimal dependencies)?

Clarification: Modifying the server side is not an option, so while alternate serializations would be convenient, they won't solve the problem here.

Some additional investigation yielded pyrolite, an MIT-licensed library that allows Java and .NET programs to interface with the Python world. In addition to remote object functionality, it (more importantly) includes a pickle serializer and de-serializer.

You can use a Java JSON serializer like GSON or Jackson to serilaise quite easily and use a python json pickle to deserialize
