Hi coolguy,

the last one is easy: NetWeaver is the plattform that ESA is running on, that means all tools and gadgets you need to actually doo something there.

Another point is the difference between SOA and ESA. SOA in general describes the technology how to do a service oriented architecture and it is more of an idea how to do it. All we agree on is that we are using web services to connect different systems.

ESA contains also the usefull objects behind it, defined by SAP and the upcoming ESA community.

As an example I had this: SOA is describing to you how to technically make a book (pages bound together, numbered, ways of printing, etc.) and all you currently can see is example books that conatin no or sample text. ESA is a real book with meaningful content in it.

Hi,

have you seen these two articles:

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/events/sdn-meets-l... web services to enterprise services.ppt

and https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/webservices/... adaptation of business processes using web services.pdf

I think they answer your questions pretty well.
