CAF (Composite Application Framework) and ESA

[Former Member]

Hi,

As far as I understand, XApps is presented as a piece of Netweaver (the column on the left side of the NetWeaver stack), an XApps is also a kind of business process based on several applications (or services ?).

XApps runtime and composition platform is the CAF and not NetWeaver ?

So I am confused and I do not understand if

- ESA and XApps is the same concept

- ESA and XApps are not based on the same technology

- XApps will be part of the Enterprise Services Repository and CAF will be rewrtitten to be based on XI so that the vision and the strategy is coherent

If someone ca nclarify, I will greatly appreciate.

Cheers.Christophe

XApps is a concept. There is no general implementation of it. You can write Xapps in Java, In ABAP, or whatever. However, there are nice tools in development to do XApps, which are completely Java based.

CAF does run on NetWeaver. As it has a "Framework" in it's name it naturally should not contain a server environment, should it?

Yes.
