LS2J don't work

I have a WebService Client Java Library named AntaresWSClientJ.I have a Lotus Sript Library named AntaresWSClientLS2J. It consume AntaresWSClientJ by LS2J(*javacon).

When debugging LS code, i get a ClassNotFoundException: AntaresWSClient, at line:

Set AntaresWSClientClass = jSession.GetClass(“AntaresWSClient”)

This worked for me on Lotus Domino 7…, bout not on 8.5…

Any idea?

Thanks
