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

 JDK version: 1.6.0


For some reason, Tomcat isn't using that JDK - it's using some other one
somewhere on the system.  What does version.sh tell you?

Thanks peter, Actually JDK was pointing to 1.4 so was not working. After it
is changed to 1.6 it is now working fine.

Something is trying to use an older JDK to run Tomcat - probably 1.5.  I
think you should look at the Tomcat service properties and check that it
is correctly configured.

I updated my tomcat 5 to 6 (beta) which I didnt have this problem. Class
version problem sometimes caused by system time. have you changes your
system time? Or try to clean up all classes you had generated and compile
your java program again see how
