when I try to connect to my database from tomcat using a
jsp file I am getting this error :

WebApp: Error 500
(File: /usr/home/builder/psa_602_patch/psa/apache-modules/mod_webapp/work/jakarta-tomcat-connectors-4.1.24-src/webapp/lib/pr_warp.c Line: 398)

can anybody explain to me what is the problem?
