Using JDBC Request in soapUI Eclipse plugin

I'm using the Eclipse plugin and trying to make a JDBC Test Request that performs a database query. When I setup the test step and test the connection, I get the error "Failed to init connection for drvr". If I do the same thing in the full GUI version, I received the same error until I found documentation that said the JDBC .jar files have to be placed in the GUI's bin/ext folder. Once I did this, it worked perfectly. I figured the same thing would apply to the Eclipse plugin (putting the .jar files in Eclipse's plugins folder), but this doesn't seem to help. Does anyone know how to make the soapUI project in Eclipse use the JDBC .jar files?
