This has to do with the fact that you compiled this servlet using a 1.5 VM and the target VM is 1.4.2 or some other 1.4 version. I wouldn't imagine a 1.3 is your target (I think that version of Tomcat requires 1.4+..may be wrong). Anyways, to fix it you need to compile your servlet with the switches -version 1.4 -target 1.4 added to your javac calls (or which ever version of the VM is the target...the VM version Tomcat is running inside). If you are using an IDE then you'll have to figure out how to make the IDE pass switches to the VM to cause this to happen. In Netbeans (4.1+) you would change you project source to 1.4 instead of 1.5..might have to change your project.properties file to use javac.target=1.4 javac.source=1.4 Wade
