How to Call webservice by another webservice

[Former Member]

Hi all,

Anybody knows how to call a webservice by another webservice.

If the caller WS is implemented as a Java EE component itself, you can simply use @WebServiceRef to obtain a reference to the callee WS. Otherwise you'd need to manually instantiate and configure the proxy. For more information please refer to [Consuming Web Services|http://help.sap.com/saphelp_nwce10/helpdata/en/46/935a636110581de10000000a1553f7/frameset.htm].

HTH!

if u have ce71 with ehp1 you can model your ws calls using BPMN ELSE can create a ws client using the slider. the code for ejb will be generated on its own.

The product you are talking about (SAP EHP1 for SAP NW CE 7.1) is not yet released to customers.
