Portal UME as user management for SAP Netweaver Gateway

Dear Experts,

We would like to know if we can use Java UME as user management for SAP Netweaver Gateway.

In our landscape, we are also planning to implement UCES for which Java UME (Portal UME) is planned to be configured.

Now, we are also planning to implement Mobile services for Utilities end customers for which we intend to follow SAP Netweaver Gateway approach.

Now, as these are 2 different set of development approaches and as we would like to have one common User Management approach for both the types of developments, could you please comment on the feasibility of using Java UME as user management for NW GW approach.

Thanks & Regards,

Anurag Gwari
