Try adding this to CATALINA_OPTS: -Djava.security.debug=all This will give you a whole bunch of information about what the SecurityManager is doing, including dumping errors when security checks fail. If you only want to see failures (which is usually the case), try this: -Djava.security.debug=access:failure If you want to know the full range of options in your environment, run: java -Djava.security.debug=help Hope that helps, - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlB1diIACgkQ9CaO5/Lv0PARYACeNGI54lL44lGSbOOArxtZ3sYB 0A8An2CM1W90Yh08C0yNMc1n8wmcR/7D =O6NC -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
