Webdynpro runtime problem

[Former Member]

Hi ya,

I am trying to run a simple Webdynpro example and I get this error shown below. I have searched for possible solutions on the forum but most of them I see are related to versioning of NWDS and J2EE Engine stacks. Currently I am running this application on NWDS stack 11 and J2EE Engine stack 9. Can I have possible solutions related to patching of NWDS to work with J2EE Engine stack 9 or upgrade of J2EE Engine stack 9 to 11? If so please tell me where from I can download and run my application.

Thanks in advance for this problem

Please post the complete stacktrace.

I guess it's the usual problem: NWDS SP > J2EE SP

Yes, that confirms my guess.

Ensure that NWDS and Web AS have the same SP number.

HI,

I think you have to upgrade your J2E engine to the same level as your NWDS.

I am not sure if you can download it just like that.Contact the support desk using your OSS number.
