as400 adapter problem

Hi all,

I’m using as400 adapter by webMethods to connect my IS to existing as400 system

using the IS Admin page i manage to create a new connection and in server log it says "succesfully connected to server application : as (connection type) "

but when i’m testing it out using wmAS400 Samples for the service wm.as400.sample.connection:initServiceTest
on the flow getConnection when i step through my AS400 object return as null but the connKey is returning a value. so the question is… is it already connected or not?
and what would i need from the AS400 if i want to read from the dataqueue, since i’m not familiar with AS400 system
