This is an indication that tomcat has either been incorrectly installed or is missing a key jar file. It seems certain distributions do not include this jar file. Download the jar manually and place it in the tomcat's lib folder,
/opt/apache-tomcat-7.0.39/lib. If your distribution does have this jar, try replacing it with the download.
