I'm not sure the problem is the servlet

[Tonya Johnson]

We have just installed Tomcat 5.5.26 and I am running test to make sure that everything is setup correctly. I get this message when I run a simple servlet that just places Hello on the screen. Can someone help me with this?

Thanks.

It looks like you compiled your source with a javac version that is higher than the Java version under which you're running Tomcat.

Either upgrade your JVM or recompile your source with the -version xxx switch .
