David, Lucene is a framework that offers fulltext-indexing and search capabilities with a very limited support for client/server communication. The only remote communication mechanism included in Lucene (I know about - but I'm very confident I did not miss anything related to that) is the RemoteSearcher which is based Java RMI. Drawn from the stacktrace you provided the error is somewhere in a xmlRPC communication. Lucene does not have any dependencies on those classes so I'm very confident that this error is not caused by Lucene directly. I hardly recommend you re-ask your question on the KnowledgeTree mailinglist.
