WS without SOA

[Former Member]

Hi;

We are implementing E.C.C. 6.0 but without X.I. or Portals,

we need to use WebServices to many devs, I know

that we need an E.S.R. to public the services and

run on a XI server or a Federate Portal.

Can I use the W.A.S. that came in E.C.C. 6.0 to replace the

use of X.I. or a federate Portal?

Should I install a Java Engine for that, like exist in NW2004s or

NW70?

Thanks In Advance

To complete previous answers, here is what you can do with a WAS ABAP, without the JAVA part and without XI:

- You can expose any function module (and function group) as a web service

=> that's the providing side

- You can create client proxies on basis of wsdl files of exposed web services; these client proxies can be easily invoked from your ABAP code

=> that's the consuming side

Thus, clearly, you can implement provider and consumer web services with ABAP only.

Hi Juan,

These are excellent questions and I believe sooner or later many people will face them, too. I for one had this exact same dilemma earlier this year, regarding SAP NetWeaveru2019s capabilities as a web service consumer. And it turned out no other components (XI/PI or portal) are needed as NetWeaver Application Server contains a component called ICM (Internet Communication Manager) which "talks" HTTP(s). Plus, ABAP workbench supports proxy creation for services provisioning and services consumption. I do not have hands-on experience on the provisioning part with just AS, though. But based on the training BC416 u2013 ABAP Web Services, it is possible.

I hope this helps.
