AS400 adapters

I am pretty new at webmethods so trying to understand a few things. I have a project that would need to connect to the AS400 system to get some information. The webmethods version i have is 6.1. AT the moment i am not sure how to go abotu getting the adapter or checking if the system does have one.

If anyone can help me to understand this further. It will be really great
