integrate nutch search engine with cms

[Abdelhakim Diab]

I am using magnolia CMS to build my site under tomcat web server and I wanna 
integrate nutch search engine in my site.
the search application coming with nutch is very good after I extracted it 
under tomcat and all I need to work is to put the index & segments folders 
resulting from the crawling operation in the tomcat/bin  folder and every 
thing is ok.
my problem is when I integrated the search application in magnolia cms the 
nutchBean class can't see the index & segments folders .
I tried to put them in many locations but in vain .
the exception is :java.lang.NullPointerException
pls any help
