[opencms-dev] Never mind - Lucene 1.5 null pointer exception

[Chris Todd]

After examining the Lucene source code, I realized that the directory
referenced by the java.io.tmpdir property for my Tomcat JVM did not exist,
and the Lucene source code fails to check if the directory exists prior to
attempting to obtain a list() from that directory.  Thus, the null pointer.

Regards,
Chris

Subject: [opencms-dev] Lucene 1.5 null pointer exception


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

Any ideas what the problem is?

Chris
