Hi,
We have a BizTalk application which implements integration with Peoplesoft. We have inherited this application which implements the following integration points:
– File published by Peoplesoft for BizTalk to collect (used for large batches)
– HTTP Post for BizTalk to send data to Peoplesoft
– Soap Adapter web services exposed for Peoplesoft to send events or small messages to BizTalk
If id been involved earlier in the project i would have evaluated the Peoplesoft adapter, but the stuff implemented above has been working fairly trouble free for ages. I think they key saving from the adapter would have been being able to generate schemas as some of them are quite complex.
There is a white paper which might help might be useful to you
