> --- ROOT CAUSE --- > org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC > driver of class '' for connect URL 'null'
The dreaded "driver of class for connect url null" error. That means that something is wrong with your database configuration, but Tomcat cannot tell exactly what the problem is. Its not always easy to debug this. It sounds like you've already checked the most obvious things: - connection string is correct? - username/password us correct? - is database user authorized to connect from machine on which Roller is installed? - is TCP/IP networking enabled in MySQL? - are you using right version of JDBC driver jars? Wish I could be more help, but that Tomcat error message gives us little to go on. - Dave
