Solved: Error in the Tutorial Car Rental application

Former Member · ‎07-28-2005

Hi! I developed the Car Rental tutorial on J2EE applications provided with SAP Documentation. I completed the project completely (and deployed it succesfully), but get an error when I add a new reservation. The error is the following:

500 Internal Server Error

SAP J2EE Engine/6.40

Application error occurs during processing the request.

Details:
