I have just begin looking into the Internet Sales Application Java code and my project requirement is to write the whole new functionality in ISA java application which is popularly known as Customer Function Module in SAP R/3 ..Please let me know what should be the architecture or design pattern i shall follow..
I assume that we have to write : -
A new Backend Interface and Class to get the data or the parameters from SAP..
A new Business Object has to be written
I have to deploy my functionality as a webservice and then it will be used by .NET application which will use this service to fill their data into this web service and thus into the R/3 backend database.
Let me know if i am not clear we can discuss this further ..
Good to hear from you ..Thanx for the reply , I understood that the JCo has to be used for taking the function modules into Java...I wanted to know the best practice of the application i described earlier..I want to know that if i have to add a functionality of a new custome based RFC in SAP , what should be my approach in BSL and Business Object layer , Obviously as described earlier that i have to deploy the new functionality as a web service
