I am creating a Web application that will issue an RFC call to SAP to execute a function module to read selected tables based on the data that was passed. We plan to create the application using Java. Can the selected data be returned in XML format? I know that Business Connector can handle this but this will be a real-time inquiry.
Depending on the type of application you are building, your XML document requirements can be extremely simple or horrendous. If you need to model a complex set of table relationships via XML, then Business Connector is the way to go. It can operate realtime and offers a more abstracted development interface than JCo.
On the other hand, if you need to simply model a table subset in XML, I recommend coding this manually in the Java application. This means declaring a document type definition containing the required field elements, and then either rendering the plaintext XML document or passing the document over a network or file stream (HTTP, etc.). Again, the implementation of XML is highly dependent on your requirements, but these are two common options when dealing with XML.
