_Theoretically_ that should work, however, the Tomcat folks don't
recommend deploying different versions of the same classes in their
container because of class-loading issues.
You shouldn't have to re-compile anything (if you used JDBC correctly),
because your beans shouldn't be using any of the classes from MM.MySQL
