you or your admin should know, under which JDK your Tomcat is running. At least it seems to be an older one than the one used for the build process.

Yes, it's the incompatibility between two JDK versions. Compiling with 1.4 and running with 1.3 will cause such an error.

Hello All,
I downloaded the source code for cocoon version 2.0.4, and ran the webapp task to create the war file. I then copied the war file into my web app folder on Tomcat 4.0.4.
However upon stopping and restarting Tomcat several times, it was not able to see the "cocoon" webapp. I then went through the Tomcat log files and found the following message :
HostConfig[localhost] Error deploying web application directory cocoon
java.lang.UnsupportedClassVersionError: org/apache/cocoon/servlet/CocoonServlet (Unsupported major.minor version 48.0)
Now upon going through the user's mail archive, I stumbled across someone who had a similar problem, except that he had the wrong version of the JVM.
However, my JAVA_HOME environment variable points to E:\j2sdk1.4.1_01, which is version 1.4 and greater. Is it possible that Tomcat is using some other JDK version, or JVM ? Please help if you know what the problem is.
Thanks in advance.
Shainal.
