InfoPath Dev

The problem we are facing is that we have established a connection from web service to SQL Server 2005 through dataset but when we submit the data from infopath, we get a message that dataset is not supported by Infopath Form Service. Is there any other way to submit the data via web service. 

 Hi, I'm Jenny's Colleague. Yes, we have MOSS 2007 and Infopath 2007. Design checker was also used and when we try to publish the form, it says that form is browser compatible but there's something wrong with Sharepoint Form Services. We couldn't find anything which could make sense in MOSS 2007.
