[opencms-dev] Lucene 1.5 null pointer exception

[Chris Todd]

I've installed the lucene 1.5 module, followed the readme, and setup the
following crontab job:
* * * * * admin Administrators
net.grcomputing.opencms.search.lucene.CronIndexManager
createIndex=true,registry=/home/me/tomcat4.0/webapps/mywebsite.com/opencms/W
EB-INF/config/luceneconfig.xml

My luceneconfig.xml file is completely default except for the <indexDir>,
which is:
<indexDir>/home/me/tomcat4.0/webapps/mywebsite.com/opencms/WEB-INF/luceneind
ex/</indexDir>

I have created the directory:
/home/me/tomcat4.0/webapps/mywebsite.com/opencms/WEB-INF/luceneindex/
And it has the following permissions:
drwxrwxr-x    2 me    me        4096 Mar 30 00:18 luceneindex

When I run the indexer, however, I get the following exception:
[30.03.2004 21:10:10] <opencms_cronscheduler> Starting job for

Any ideas what the problem is?
