Java Web Dynpro + User Mapping

[Former Member]

Hi

We want to use Java Web Dynpros for Portal users to run some backend ERP functionalities.

In order to avoid ERP licenses for all Portal users, we want Portal users to be mapped to a common ERP user.

This workaround is clearly valid for ABAP Web Dynpros, but can we use it for Java Web Dynpros?

We tested some standard iViews (from ESS), but didn't succeed.

Thanks in advance,

Hi Jon,

Use the ERP User and password while creating the JCO Destinations, both for MetaData and ModelData.

I believe you are using Standard ESS iViews only for test purpose, otherwise you are going to build your own Java WebDynpro Applications [just assumption] because if you want to actually use ESS / MSS business packages then you would need ERP Users, HR Users to be specific and also maintain their data in the ERP System.

What about security and logs? How do you plan to handle it?

Hi Vaishali and Mrityunjay

Yes, I am using ESS only for testing, before we go ahead with some custom Java Web Dynpro developments.

After configuring both JCo destinations with UID and PW, I'm getting the next error:

com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: ComponentUsage(FPMConfigurationUsage): Active component must exist when getting interface controller. (Hint: Have you forgotten to create it with createComponent()? Should the lifecycle control of the component usage be "createOnDemand"?

I might be missing some configuration?

Thanks,

Hi Jon,

Most of the Applications are dependent on the homepage framework configuration.

Try to test the "OrgChart" iview under Employee Search.

If you have configured both the modeldata and metadata then you are not missing any configuration for continuing and developing applications.

Hi

All the tests we did with the standard ESS Java Web Dynpro iViews were unsuccessful.

We created a simple Java Web Dynpro component linked to a custom pair of JCo destinations... and we proofed user mapping is possible.

Thanks all for your interest,

Hi Jon,

Yes, user mapping can be used for Java Web Dynpro as well. If your ERP functionality is not specific to individual user then user mapping can be very well used.

In case of ESS/MSS as the backend data is specific to individual user, users would be mapped to the corresponding backend user or logon tickets would be used.

What error do you get in ESS standard iviews after doing the user mapping.
