I have recently asked for a requirement analysis, when my customer wants to have some layer ADF and Web service communication (May be web service proxy). Prior to that they were using "Java TIBCO Client" & "TIBCO Insulation Layer". Now they want to replace TIBCO(JMS/SOAP) with Web services (HTTP/SOAP).
If we introduce any layer in between ADF managed bean & web services. So the benefit is we no need to take care of source code in case of any parameter changes in the web services.
In case you have any idea/solution on this please share.
