Hi,

First check the DC if it is defined usage of other DC's.

in WebDynpro Eplorer

Expand <DCName>> WebDynproComponents<CompName>> UsedWebDynproComponents>

If yes, Check if the used DC's are built and deployed into server or not once,

Regards

Hello!

I face the same problem with Failed to create delegate for component:

com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to create delegate for component

XXX.YYY.ZZZ..ume.Ume. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)

Caused by: java.lang.reflect.InvocationTargetException

Caused by: java.lang.NoClassDefFoundError: com.sap.tc.webdynpro.model.webservice.gci.WSTypedModelClass

I think this started after upgrading from 7.01 SP3 to SP5, but I'm not sure.

What was it that solved your issue?

*I found the error. My ProjectProperties.wdProperties did not contain the references it needed.*

Hi,

If the DC is dependant on any other DC try deploying the Used DCs first.

Check if all the Library/ Sharing References required are mentioned correctly.

Lastly try changing the Component Name and redeploying the application.

Thanks

hi ,

first check whether u have made the dependencies perfectly to ur component .

then go to the development Infrastructure perspective , righr click ur component -->Sync /Create project -->Sync Used Dcs

select all the components and build the components .

finally deploy the dependent components and then deploy ur Component .

Thanks and Regards
