Yep, sounds like you have a database connection problem...

Please post your roller.xml file here (blank out any passwords first)
and we'll take a look.

Did you put the MySQL JDBC driver jar in tomcat/common/lib?

I'm trying to install roller 3.1 on a windows server 2003 w/ sp2. I have tomcat 
5.5, MySQL5 and J2SE 5. All of those are working correctly.

As of right now I'm getting the infamous "Cannot create JDBC driver of class ' ' for 
connect URL 'null'" statement in my roller.log. I've tired everything suggested in 
the things to check section and it still isn't working. I've also done some outside 
research and I'm confused about which sections I should alter in the roller.xml context 
file. The install guide says to change the URL, but outside sites with their own install 
steps say to change the resource. Does this also refer to the URL or does this refer to 
the name?

I only get this error when I put the path to my roller database in the resource name. 
When I put it in the URL I get: "Cannot create JDBC driver of class 
'com.mysql.jdbc.Driver' for connect URL 'C:\www\mysql5\data\roller'".

Any thoughts or directions on how to fix this would be most appreciated.

Thank you.

Kelly
