In the Appeon Code Examples demo, the “EJB Component Lookup failed" error message displays when the NVO calls function of EJB component.
Cause: The environmental variable is too long.
Solution: Reinstall Appeon Server.
Before the installation, be sure to shorten the path for the environmental variable. Another option is moving some driver files from the %EAServer%\java\lib folder, and moving them back after the installation.
