Yeah, you have a corrupted zip file (or something that's not a zip file) in a place where Tomcat is expecting valid zip files.

Check your Tomcat installation (all the zip files under it) to see if any of them are corrupt. If you aren't sure, unpack a fresh Tomcat from an official downloaded .tar.gz or .zip distribution.
