Not easily, it is even hard to use SAP Portal technology with R/3 4.7 systems. The main govering feature of data exchange between systems in R/3 and NetWeaver 7 is the RFC function call. The main interface of data exchange between systems in an ESOA technology is "SOAP". Things get even worse from their on. The main user interface in ESOA is the WEBGUI (just a plain old browser engine, anyones on anything - I once had an instructor tell me that with ESOA output you could run it on an "Etch-a-Sketch" if one could figure how to hook it up to the network). FAT Client GUI (already a dying interface) and Portal Technology interface are NOT the primary interface for end-users (though the portal can be used as the back drop). Lastly, most all CE coding is done in JAVA, NOT ABAP (though back-end coding in ABAP is certainly possible). It is also structured differently. NetWearer 7 and R/3 technology is still platform based (i,e, erp systems BI systems CRM etc). One has to know where the data resides. In a CE environment though the same systems are still used (ERP6 BI7, CRM2007 etc...) the data repository is translucent and controlled access by the Object Repository. Before you try to leap into ESOA, take at least the initial classes in your area of expertise (and pray it isn't BASIS like mine). Then, ask your questions of yourself, you will know the answer.
In answer to the WEB SDN URL listed above from 2005, I did not say it was impossible, just remember your life in ESOA is JAVA!! - with R/3?? Your Development Environment is Visual Composer and your development system is NetWeaver 7.1 CE (and no that is not just a minor upgrade!).
