XML IDOC data (hosted on a web server) & handling multiple WSDLs

Hi ALL,

1)how to design an Interface for picking up an XML IDOC data (hosted on a web server) which will be uploaded to SAP or converted to a file

this is what the customer has given me ..can any one explain me this and help me how to more forward

2).This Interface must use UDDI concept because we are going to use multiple BAPIs /RFCs as WSDLs

what is this mean can any send me some document on this

3).Use web-service navigator concept as we will be handling multiple WSDLs

i worked on 1. to define a place holder in WebAS for holding the

wsdls.

2. publish the wsdls in WebAS UDDI Repostory

but i have never used web-service navigator concept as we will be handling multiple WSDLs what is the difference ..send me some step by step docs ..

thanks very much

RK..
