problem getting a nullpointer exception when porting to linux
hi everyone!
could someone please help me...
i'm getting a null pointer from the line:
hits = searcher.search(query);
i can't understand why, it only happens in a linux environment, not on my development XP environment....
i've re-indexed but that didn't seem to help...
thanks in advance
regards

Brian,
the line of code you pasted is not very useful to see where the problem
exists. Could you please provide a small sample how the index is
generated and the query is sent to lucene. If that is not possible,
maybe the stacktrace could be helpful also.
Thanks
Bernhard
