i tried to connect to MYSQL but i received the message: org.gjt.mm.mysql.driver ? why ?
My suggestion would be to use something like DBVisualizer to get the query string correct and formatted correctly before attempting to create a connector for it.
Download it and use this to connect to the database in question. It will actually give you the full URL string for the connection and you can then use this for the connector when you are testing it. However, DBVis comes with a bunch of drivers built in which might not be in the connector framework. So double check and copy the relevant lib file to the current/lib/agent folder (I think - check the manual on this).
Once you get the connection string, it should start working. However, I dont recognize the driver below - what is it for?
