Bad version number in .class file

I was getting the following error:

java.lang.UnsupportedClassVersionError: Bad version number in .class file

I understand it is because I was trying to run a .class or jar file that was compiled with a higher version of java than the virtual machine I was using to run it.

I downloaded and installed the latest version Java SE 7 (I use linux SLACKWARE).

I set Java_Home and Path to point to the version of java using "export"

I restarted tomcat and it recognized the new JAVA_HOME.

I ran the jsp and still got the Bad version number.
