Just installed Apache and Tomcat. Everything seems to work ok, however I wanted to test out Tomcat and put a simple jsp file http://localhost:8080/jsp-examples/o.jsp and get this error:

What does this error mean? Do I need to reinstall my JDK?
thanks,
Alex

There are two problems:

j2re1.4.2_03

This is a JRE, not a JDK, so you (Tomcat) will not be able to compile JSP's. So alter JAVA_HOME to point to a JDK. If you've already installed Tomcat 5 as a Service, try uninstalling and re-installing, this time making sure Tomcat picks the JDK for JAVA_HOME.

the second problem is:
class file has wrong version 48.0, should be 47.0

I'm not sure of the exact reason, but this normally happens when people start mixing JDK 1.3 and JDK 1.4

thanks Mike,
but after reinstalling Tomcat and making sure I chose JDK directory, I got the same error -- it still says "bad class file: C:\Program Files\Java\j2re1.4.2_03\lib\rt.jar(java/lang/Object.class)." How can I change my JAVA_HOME for Tomcat manually?
thanks,
Alex
