Application Development Software

Hi All,
we have quite interesting integration scenario for one of our customer

1] Customer has one department which runs on .NET framework. The Dev team isgood @ .NET development. They have couple of business application developed using the .NET framework(ASP)

2] They have SQL server hosting the entities required for the database.

3] They want to use the Oracle Webcenter to deploy the portal in the organization/department. Since they have very good talent pool for .NET developers; they do not want to switch to ADF to show the CRUD screens for the entities.

4] They have Web Services Developed for each and every entity in DB.

5] Let say there is person entity in the DB. They want to have the Search/Update/Delete/Create flow in webcenter portlet. They do not want to use the ADF for the same. Using the data services created for the entity above; we may need to create the UI for the Person CRUD operation.

5] .NET web services can exposed the HTTP POST binding for the Web Services. So I can invoke the same using the Form Post.

6] I know WSRP can achieve the UI services Integration. I think with WSRP; WebCenter can consume the .NET ASP web application and show the same using the portlets.

7] I can use the BPM/BPEL for orchestrating the CRUD operation(kind of advanced workflow).

My major concern is how Can I call data services using the portlets and converting the XML output back in UI at portlet stage.?

If WSRP is good solution; then I wanted to know that how can I convert the data Services into UI services and consume the same using the WSRP?

Waiting for your response
