Consuming SAP Gateway Service in Java WebDynpro

[Former Member]

Hello,

We are planning to implement SAP Gateway version 7.4 and we have choosen Central Hub System as an option. Grateful if someone could clarify on the below points;

1. Which is the best development platform for UI which will consume Gateway Service. These developments will be deployed on J2EE Engine (on EP) and this development will be used of desktop purpose.

2. How to connect J2EE Engine (EP) with SAP Gateway System? We are looking at something similar to JCo/WS Destinations. Our understanding is that credentials has to be maintained in the development (code) as a clear text to establish the connection to Gateway server. This could be a security issue.

We are using SAP EP version 7.30 SPS5 from quite a long time and choosen Java Web Dynpro as a UI technology in which we consume Web Service (from PI) via Web Service Destinations.

Thank in advance.

Regards,

Anil Patil

SAP Gateway exposes the functionality as an OData Service.

Java Web Dynpro does not allow consumption of OData services. It only supports SOAP based Web Services.

No need to JCo while using OData services.

Preferred UI would be SAP UI5. Its a niche market and requires skills on Java Script. However, its not fully tested on many customer production environments. Its a risk but worth it as SAP is projecting UI5 as their preferred UI in their UI roadmap.

Check the compatibility/feasibility of deploying UI5 applications on existing 7.3 portal server.
