Hi Friends,


I tried to upgrade my tomcat server from 5.x to 6.x, when i started the
server am getting the following error.

Exception in thread "main" java.lang.UnsupportedClassVersionError:
org/apache/catalina/startup/Bootstrap (Unsupported major.minor version 49.0)

My tomcat version: apache-tomcat-6.0.20

JDK version: 1.6.0

OS: Unix

Thanks,
PHani.
