ESS Web Dynpro Error

Hello All,

I'm running into problem running ESS Web Dynpro application via SAP Portal.

Current set-up is:

-SAP NetWeaver Enterprise Portal 6 SP9

-WAS Java 6.40 SP9

The SLD is configured and I've maintained the JCo connection mentioned in documentation. I've tested the connections for both meta data and the data itself. The connection work fine. The portal has been configured includes creating system in landscape etc. The problem is when I try and run the Web Dynpro in portal I get the following error:

Any ideas anyone?

The general rule is that you cannot run a Web Dynpro application build with a NWDS that has a newer version than the Web AS.

That's because the newer NWDS may generate code that uses runtime features not supported by the older Web AS.

In your example, there is a new interface IWDEventId that is not known to the SP9 Web AS.
