Subject RE: BOOLEAN EXCEPTION APPSERVER SOLUTION
Date Mon, 14 Feb 2005 06:23:52 GMT

Hi Guys

Apologies........

The form was Correct,

The problem of CLASS LOADING  was or may be a bug with the Version jdk1.4.1
and TOMCAT5.5.3 on Gentoo O/s.

So I switched to jdk1.4.2 and every thing seems to be in proper Order as of
now.



Thx for the advise
With regards
karthik

Do a search for lucene jars, something like:
# find $TOMCAT_HOME/ -name "lucene*.jar"

Replace $TOMCAT_HOME with the correct dir to your tomcat installation.
Also check the classpath of the user running tomcat.
