EJB Model: Not all Refrences could be resolved

[Former Member]

Hello,

I have create a Composite Application (Development Component) with SAP NetWeaver CE 7.1. There I have create an Application Service where I import RFC modules which I mapped to own methods.

Then I have created an other Development Component. It's a EJB Module. In this component I use via EJB invocation (@EJB) the modeled methods of the Application Service.

Now I want to use the EJB Modul with Web Dynpro. I do this described here http://help.sap.com/saphelp_nwce10/helpdata/en/45/dd45e4bc295595e10000000a1553f7/frameset.htm.

If I create a new Model in Web Dynpro I'm able to select the local Interface of the EJB and its methods. But if I click on <i>Next</i> the Wizard don't go to the next step. At the bottom the following message is shown up: <i>Resolving References finished in 30 sec with: Not All References could be resolved</i>

I think this have sth. to do with CAF because after I click on Next the following Message is shown: <i>Refreshing DCs of SC 'CAF' finished in 0.3s with: Refreshing children of SC: CAF</i> and after that the posted message above is shown.

I think I have to add in the <i>Web Dynpro DC Dependencies</i> a dependency to a CAF DC.

Do anybody know which CAF-DCs I have to add and which <i>Dependency Details</i> I have to configure?

I tried this with DCs: <i>caf/runtime/ear</i> and <i>caf/core/ear</i> with Dependency Details: <i>Build, Deploy and Run Time</i>. But same result.

Hi Armin,

If you want to implement CAF DC in Webdynpro then you should be using the DC “caf/eu/gp/api”. The dependency details for the same would be build time, Deploy time, Runtime.

Also you need to add Webdynpro References --> Library reference --> caf_eugp~api.

This link should guide you..

In NW CE the above specified components would be in different SC's. You can find the above mentioned DC and Reference in the GP-CORE SC.

Hello,

first of all:

With SAP NW CE it is not possible to add Library references in Web Dynpro:

"The usage of Web Dynpro references (expect JCO references) for Web Dynpro development components has been deprecated; it is no longer allowed to create new references or edit existing ones. If you need to create a new reverences or change an existing one you should define DC dependency of type "At Runtime" to the required DC project."

Independent of the text above: With DC “caf/eu/gp/api” it doesn't work. This is the DC to implement Web Dynpro as Callable Objects for Guided Procedures.

I need the Reference for CAF.
