Please be specific. > MySQL Connector is also in the classpath of the PC. A normal Tomcat installation will ignore any CLASSPATH setting. You should not try to use the CLASSPATH for anything at all. You should also make sure that the MySQL Connector/J library is only available in one place in the ClassLoader hierarchy: namely, in TOMCAT_HOME/lib. > The context.xml file in the web app is set to use the root user in > MySQL and all relevant authorities in MySQL are set. This is a bad idea: you should use a MySQL user that doesn't have SUPER privileges. > Code seems to be wrong only in IE so must be something to do with > security settings.
