Whatever configures your DataSource must take those values and use them in a meaningful way. What code reads those values and configures your DataSource? Go read that code and see whether it cares about the trust store and other parameters you are trying to send it. - -chris -BEGIN PGP SIGNATURE- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAlsW8IIACgkQHPApP6U8 pFhwSxAAyolyp7SZWmpzxkM0+6HSj+tRaFTsGdMLAdPF0vg0Pd3tWzQcbpQeOeRl t+gjWHKwmO351HZVKzj5oV+o+luvlGMZbvL+ZLqv42o1RSYYBKShRnHHE21XxPlA 0yZjNQS+2wnAfxK7WM7UeGRUdaHDUrEzzx3fe5GmWUsZ+/lfBgDsu+z654WSl3ey V3NF9alctewmOXjHdNT0T6pWjBP+zF7qzv6SOXkatvoiEqi43QXg+cPZ//W01654 kBvsbv5A5iXNXi0nlcfUs+j1KWsKxQbEsmu5T7tTowHuguWTH9NqKJzkSfuRdUjj 5lX96/nJc/LQ163C6WQrb7yh+ZQ2c/iIRiqPdpoQ9rPR8t71Q5/EwtX/jDDoBI66 JowyiqDFN9otmDCT4rLmEF2iurzbaxTDmf+NRQUG54aS96tAGgGOnzY8soqxvi/+ PB8dAiQnbwcgAz+C0lDoRH/O3zjLcjY3kj2LO0l4dUHLwEB4DUDMwTZVq6U9baRO nQGql5HqD2Zn3U5f1b7ECRGBGxykdDXDGbYsFo6XWIDThmscc2Vxk1xI3fFJzxOd YofYRR9PktLAaiLI8uip+t+vS92GIam/Cq31lhHJ4L/mtYqStj/r7HVGdryqJIbT cbaoLzQ6sAd8tnr6gjmyPOWzDLC/Q+723Aw6S2DuhKraMb6RDpA= =MlNL -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
