Problem integrating BizTalk with SharePoint Portal Server

Hey, i have designed two different scenarios for integrating SharePoint Portal Server and MS InfoPath using Biztalk Server 2004. but in both scenarios i am unable to find the results. when i post a document then the receive port is not activated and same is the case with send port. i am afraid that i am unable to set the send and receive locations of a sharepoint site. tell me is there any specific way to set these addresses. my sharepoint portal server is hosted on a different computer but on the same domain. i have used following url for my site.
