What part is deprecated? The Embedded class itself? Why not just switch-over to using the Tomcat class?

It will probably be easier to spot a place where you've missed something important (or have it out of order) than to just look at the stack trace above and try to debug Tomcat in order to determine the original mistake. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with undefined - http://www.enigmail.net/ iEYEAREIAAYFAlDHUbIACgkQ9CaO5/Lv0PD+kQCfQ0i2evO0hn7g0E66MlpHpy4Q jfsAnjOqNnKIHZRlK/zuDsr4VssZQVZR =josl -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
