[opencms-dev] Lucene 1.5 on Linux doesn't work for me, please help

[kaffamanesh at dmu-world.de]

I'd installed lucene 1.5 on opemcms_5.0.1 (on win2k3 and suse9.1 (kernel
2.6), on windows it was setup within 5 minutes with tomcat 4.1.29.

Now I'm getting the following error on Linux with tomcat 5.0.25, my
registry.xml contains:

	<directories>
-
		<directory location="/release/en/DEVELOP/" >
          		<section>DEVELOP</section>
         		<subsearch>true</subsearch>
        	</directory>
		
	</directories>

under develop I have *.pdf, *.doc, .txt, .html and .htm files

and my indexDir is:

<indexDir>/home/ark.old/indexDir/</indexDir>

Lucene 1.2 could write her indices in the same directory on the same
mashine

any ideas?
permission problems, what means the Unknown Source message in the trace
below?

thanks for any help in advance

kind regards
Arash
