Thx for the reply. I tried those lock-methods already but still cant it get to
work. Heres what i did in my RequestHandler at least.
Type "Directory" and all Lock stuff comes from org.apache.lucene.store.* and
the copyFiles method is the same as for the replication-RequestHandler.
I still never see a lucene-xxxxxxxxxxx-write.lock file inside the index-dir as
i see one when the index gets optimzed...
have a good WE,
regards Alex
