I have Java 1.6 and Tomcat 5.5 installed on my system.
But Tomcat 5.5 accesses Java 1.5 and hence as the outcome I get the error Bad version number in .class file while executing java code with JSP.
How can I change the Tomcat version to Java 1.6?
UPDATE
I tried changing the JVM that the tomcat5w.exe is pointing to the version 1.6 and now I am out of the Bad version in .class file error. But now, I get the following error.

What might be the root cause?
When you open catalina.sh / catalina.bat, you can see :
Environment Variable Prequisites
JAVA_HOME Must point at your Java Development Kit installation.
So, set your environment variable JAVA_HOME to point to Java 6. Also make sure JRE_HOME is pointing to the same target, if it is set.
Update: since you are on Windows, see here for how to manage your environment variables
