My purpose is to consume a Service Interface (ESR) in Web Dynpro Java (Import Adaptive Web Service Model). But the created Model has no endpoint. I also don't understand where i have to implement my business logic perhaps also in ESR in a Model and Object definition, is this possible? Where would you implement the source code (logic)?
Your business logic has to be implemented in the system that will be providing (provider system) the data / info etc.
e.g. You want to create a web service that allows you to update a customer's address details in SAP ECC & this functionlaity should be triggered from a Webdynpro Java User Interface.
- Webdynpro Java is the consuming application (also called consumer)
- SAP ECC is the backend system OR provider system OR provider
In this case your business logic will be in SAP ECC.
If you choose to go with a point-to-point scenario:
You could first setup a connection between SAP ECC (provider) & SAP PI. You could then model your inbound service interface in SAP PI. Now because you have visibility between SAP ECC & SAP PI, the service interface modeled in SAP PI become visible in SAP ECC (TCode SPROXY). You would then generate a provider proxy from this service interface & implement the business logic in there. Once the proxy is activated you can then configure an endpoint for it using TCode SOAMANAGER (see lots of guides on how here in SDN). In this case SAP PI is only used at design time just to model the service interface. At runtime Webdynpro Java would talk to SAP ECC directly via the endpoint that you would configure.
For a mediated approach:
Pretty much the same concept as above except this time you would also model an outbound service interface & map the inbound & outbound interface. The call would then be routed as follows - Webdynpro Java -> SAP PI -> SAP ECC but the business logic would still be implemented in SAP ECC.
There are lots of technicalities around this but there are lots of guides on SDN relating to this.
Nope. After you've done what you need to do in Web Dynpro you will still need to configure a logical port for this consumer. You will need to specify the service endpoint when configuring the logical port using SAP Netweaver Administrator.
So you only essentially use the WSDL to create you Adaptive Webservice model at design time. At runtime (which is when the endpoint get's called as specified in your logical port) is when the business logic actually get's executed.
