Solved: Cannot Run the WebDynPro Application

Former Member · ‎01-13-2005

Hi,

I want to be able to deploy and run a Webdynpro application.

I have created a simple Webdynpro application with just a text view in it.

My application deploys successfully.

But upon execution it shows an error that the application failed to delegate.

SAP J2EE Engine 6.30 SP 03

NWDevStudio 2.0.5

An error has occurred:

"Failed to process the request."

Error stacktrace:
