hi all
purely due to a policy decision, we would like to host our lucene search

What would be the best way? Use Lucene outside of EJB. It's quite
silly to make such a decision "purely due to a policy decision" when
the technicalities of it show that it is an unwise decision.

You need to create a lucene index from the database.
Just index the columns and the records from the database.
It will be useful to have also a field in lucene that contains the
database's primary key, so you can retrieve the actual record from the
database

Infact we do the same exact thing. Session bean method called search()
delegates to a POJO SearchService. We lazy load the IndexSearch cache it in

I just create a new IndexSearcher, leave the old IndexSearcher alone,

Looks to me like you're using an older version of Lucene on your Linux
box. The code is back-compatible, it will read old indexes, but Lucene
1.3 cannot read indexes created by Lucene 1.4, and will fail in the way
you describe.
