Using Groovy to create JDBC connection in startup script

I don't understand how to make a JDBC connection in the startup script...

http://www.soapui.org/Functional-Testin ... ripts.html uses the soapUI pro instructions...

It works fine when everything is all in my test case in a single groovy script (not using setup script)...

I think my problem is in understanding context.

I am getting cannot invoke method "method here" on null object
