Summary

0002584: hessian Lucene serialization

Description

(rep by Matt Johnson)

I am trying to use a Lucene index and place my documents to be indexed
into a JMS queue. The Lucene Document class is documented as being
serializable.

When my queue listener tries to work on the submitted lucene Document
object, I get an error:

could not index doc: ObjectMessageImpl[ID:DOmYA38A3joAEZMMeI8wAK]

I've tried this with Lucene 2.2.0 and 2.3.1 and the same error occurs. I
am using the Resin 080331 snapshot. Any pointers or work arounds would
be helpful.

Notes
(0003150) ferg 06-09-08 09:32	hessian/3a49 Added FooSerializerFactory with a Object writeReplace(Foo foo) method which will allow wrapper classes for legacy classes like the Lucent Field.
