serializing jython objects in java

I followed the instructions here for using python objects in Java. However, in Java, I need to serialize a object which contains the python object. The java object itself is serializable. So, may I know how do I do it?

I got the error message

java.io.NotSerializableException: org.python.proxie开发者_如何学Gos.MorphyWrapper$MorphyWrap$1

when I attempt to do so.
