SoapUI + sqlite-jdbc = class not found

I'm out of ideas. Have anyone ever succeeded in using SQLite in soapUI?

On startup I get a proper log about library being added to extensions classpath:

INFO:Adding [/home/piotr/soapui-4.0.1/bin/ext/sqlitejdbc-v056.jar] to extensions classpath

I have added an import to my MockService Start script, now it looks like this:

import groovy.sql.Sql
import org.sqlite.JDBC

def sql = Sql.newInstance("jdbc:sqlite:/home/piotr/workspace/SINUM-soapUI/test.db/", "org.sqlite.JDBC")

When I start the MockService i get the following error:

java.sql.SQLException: No suitable driver found for jdbc:sqlite:/home/piotr/workspace/SINUM-soapUI/test.db

Error log says this:

Sun Jan 08 12:11:23 CET 2012:ERROR:java.sql.SQLException: No suitable driver found for jdbc:sqlite:/home/piotr/workspace/SINUM-soapUI/test.db

Do I need to add any additional settings files to tell soapUI that my project uses an additional library from bin/ext/?
