I am unable to start Tomcat with a JDBC Realm
configured. I am guessing it is because Tomcat can't
find the JDBC driver, but it should be able to. I have
the driver in shared/lib and shared/classes. Here is my
Realm configuration from server.xml:
<Realm
className="org.apache.catalina.realm.JDBCRealm"
driverName="org.gjt.mm.mysql.Driver"
connectionURL="jdbc:mysql://localhost/dbmis?user=uname&
amp;password=pass"
userTable="users"
userNameCol="userlogin"
userCredCol="userpass"
userRoleName="usergroups"
roleNameCol="groupname"
debug="99"
/>
I added the %amp; when Tomcat wouldn't start because of
an XML error when I had a plain '&' in there.
This is the relevant section of catalina.out:

MySql logs show nothing, so I don't think it's an
authentication problem or anything like that. I'd
appreciate any ideas or suggestions anyone has. Thanks
very much.
