</process>the above is the server and client wsdls and Bpel process. i have created the wsdl so as to call from HTTP calling, means process is been called from Browser .... but i can't see the result ...
http://sys0004:8889/httpbinding/default/getOpenInvoices/OpenInvoices?accountNumber=1608
above is the link called from browser
output in the browser ::: <getOpenInvoicesProcessResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.oracle.com/getOpenInvoices" />
actually it has to fetch data from DB and show in xml format can anyone assist me where i am going wrong

Hi Rajesh,
Please refer \bpel\samples\tutorials\102.InvokingProcesses\jsp.
BPEL Tutorial 7: Invoking BPEL Processes through SOAP and Java : Reference: 2004/06/14/orabpel/d5/1.0
Hope this helps!
