Import a Java Bean from a different DC

[Former Member]

Hi,

we have imported a java bean model in a web dynpro DC and the java bean is located in a different (Enterprise Application) DC.

The import worked well, but when we run our web dynpro application, we get the following error:

[code]com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to create delegate for component net.dsb.zhsgui.prototype.view.hilfeland.HileLandExampleComp. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)

This hints, that the Java Bean code is not found at runtime. Do we have to declare a dependency in Web Dynpro to that Enterprise DC and if so, how can it be done?

Any help to this topic is appreciated.

Kind regards.

Hello,

right click on dynpro project, select "Properties". Select "Web Dynpro References"->"Sharing references", add name of your enterprise application (including vendor, e.g. "sap.com/enterpriseApplication").
