Can any one explain the different between them?
1. Can the Adobe Flex (VC) interact with the SAP program directly?
E.g Flex -> SAP back end
2. The SAP system must interact with the Webdynpro first. Then, the webdynpro generate the XML code (or other code) and interact with Webdynpro
E.g Flex -> Webdynpro -> SAP back end.
3. In fact, can I consider Webdynpro = Tomcat. Which is just an Application server.
So, the Visual Composor can interact with the SAP backend directly while the webdynpro just Installed.
Which means NO java code needed. Just Flex -> SAP back end. and Webynpro/Tomcat, install and forget it?
