How to view soap request based on webservice url?

I need to call SSRS Report WebService using jQuery ajax request. Since the ssrs webservice is SOAP based and considering the example shown for "calling share point web services using jquery" I think I need to pass a soap envelope.

Based on the ssrs webservice url how can i find out the soap envelope require开发者_运维技巧d by a particular method? (except fiddler)

Thanks

You need to have a look at the wsdl file! wsdl file explains it all!
