Use a generic wrapper object.  E.g.

public class Wrapper {

  public Object obj;

}

Use the wrapper's schema to serialize/deserialize.

Thanks

I am sorry to ask you a question here. I have already post a topic but I can not see my question on the list.

I try to serialize generated AST information from Eclipse-JDT parser.  The exception message is shown

Exception in thread "main" java.lang.RuntimeException: Not able to map any fields from class net.core.dom.NodeEventHandler.  All fields are either transient/static.

However, the NodeEventHandler class is full of default implementation methods that do nothing.
