Multiple Datasources Driver Error

In reference to http://community.jaspersoft.com/wiki/multiple-datasources-ireport-lists-...

I've followed these instructions, switched language to "Groovy", and pasted my jdbc driver in just about every /lib/ I can find. Also, this was working just fine yesterday. I'm dead in the water on this.

My setup:

- I have a primary datasource that works well, the main query returns values.

- I have a secondary datasource that tests successfully, and if I use it in another dataset, records are returned.

- As soon as I add a parameter to the main report, java.sql.Connection, with the default expression, java.sql.DriverManager.getConnection("jdbc:rssbus:salesforce:user=aaa;password=bbb;AccessToken=ccc","aaa","bbb")

I get this error:
