Getting SOAPEnvelope from wsdl and operation

[Wishing Carebear]

Hello:
I'm trying to build a testing framework for webservices. The requirements are as follows:
a. for a given oepration, may be the user can send the parameters values
b. Show a Sample SOAP envelope and the user can change the value directly.

Is it possible using axis1 to get a sample soap message for a given wsdl and operation.

Thanks for your help and time,
regards
