As Java Dynpro is running on independent J2EE server, the only way existing to talk with SAP systems is through RFCs or Web Services exposed by the SAP(R/3) systems.

Hello Frank,

Access SAP R/3 From Web Dynpro would be using ABAP Functions (BAPI).

You can call ABAP Function in many ways.

Easy Would be - Adaptive RFC Model

Here is documentation for that....you can find examples also from here.

https://www.sdn.sap.com/irj/sdn/webdynpro?rid=/library/uuid/49f2ea90-0201-0010-ce8e-de18b94aee2d#15

JCO connections

First you need to create JCO Connection, then using jco connection you can call to any ABAP function.

BAPI Exposed as Web Service.

This is also simple. Once web service is ready you can use it as normal web service.

You can create communication from Portal using Transaction iviews, it is same as R/3 but from portal.
