Oops, it seems I misunderstood the instruction, thanks.
But I'm still stuck with setting up the LCF...&nbsp; I created the DB and installed the agent.
When I go to [http://localhost:8080/lcf-crawler-ui/] after starting the agent, I always receive a NullPointerException:

{noformat}
type Exception report

message

In reply to a comment by Karl Wright:

If you didn't include any connectors that require defines, that directory won't be generated at all, I believe.  The connector that generates most defines is the jcifs one, so if you didn't include that you are getting the expected results. ;-)
