Java mapping - java.lang.UnsupportedClassVersionError

Hello gurus,

I'm new to java mapping and trying to test a simple one. When I try to test my mapping in an operational mapping, I get this error.

I used aii_map_api.jar, also imported it to ESR and developed the mapping as we used to in PI 7.0, but trying to run it in PI 7.1. I do not know what has changed, links to java mapping in PI 7.1 will also be appreciated.

Regards,

Gökhan
