BPEL process as web service data control

Question

Hi,
I am trying to invoke a synchronous BPEL process from a jspx page. I have configured my BPEL process as web service data control object and
dropped it on my jspx as a button. But after dropping it as a button i observe that it is expecting three parameters.
I have attached the .xsd file used in the BPEL process and the screen shot of the parameter window of JDEV.
Here if you can see, i have a heirarchy of data. I have customerType which has orderType , which further has lineType.
Can somebody help me , how do i provide data to this process i.e in the parameter fields., so that it is in accordance with my .xsd of the BPEL process.
-thanks,
lavanya.

Every BPEL process is an another web service. Go and grep WSDL of the BPEL process and call it.
