Hi all.

I was testing my web dynpro app, and it has worked very well and suddenly it let work and gives a '500 Internal Server Error'. And the error is:

Application error occurs during processing the request.

Did you upgrade some components on your J2EE engine lately? There is obviously a version mismatch between the Web Dynpro runtime and the licensing runtime component.

Hi,

It sounds as if your WebAS license has expired. If this is the case you can restart the J2EE engine via the SAP Management Console, but it will stop working again after half an hour.

Basically, you need to install a new license key. Enter quick link "likey" in the SAP Portal to request a license.

Hope this helps,
