You are not using classpath-based config-file-loading, so it should not be a problem[*]. > 2. We are observing weird things in rolling the files hourly.

Because log4j.jar is in each application's class loader, they CAN have different in-memory configurations. [*] While this will work, why would you ever want multiple applications to have their logging configuration all tied together? Why not separate the logging configuration into one config-per web application? OR are you trying to unify all logging into the same file(s )? - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAlxtdSUACgkQHPApP6U8 pFhxow//T+5ALVYJcljqLxykHND7ZSy9NHf0+a+jnWzlDO5S6oO+bxjso9raJZYC jUG4nhBwuAtD5MWyS04t0UedYUBP+n1iw4aAGs7PrhFgPxLiHZpMOTBBaeDSYgny bI+7GuqOhkiauPA8Jb6guE8SkrT18d9X+k7xzy6puYgqbTws0iwk2yEmSV+KNtXy 0EsVC20KGhU9pCdD7MLSpYX8PaM8sctazxSSVMygL9Ed03WKkJ6BRPavq4ao1uGg V0ZlTQb7f9PRPOXOQzoAlsaWNTCVRKQES82/HHJE/uJG5tg7jnQ5Syjs53FyfVwH 0AtfNpJiOI4LES5ejR7E5JZ8Lx0/J41XwsPO5hOmYaiHHs35EFtozCETNNwjYxcb 245z++YsBw0bnBDRpAFi5Kq5UL8ludo0CqDTfKQSIqrMoNHoiULm4U3niGl2P01w O8k2KrwqtYWu77esh+TpJpXTTaLnEhCc+YWFGWnER3w8WAOHitvjbmAi21gL3NIG 3PJEFEdrNMaoI2h3SkK+DJzuVVJRmXRMV2wduX4+3qGW6l31Jo3ihFiDDdXyGB+b jtpU1JHYfYP+ck8mEXgOvI6RXZEG7R8Ef7ectYuKdhRRpE+S9wx1llZminsxY/fr 0apA+L6paBo9R7EGxJVt237wx/L+tRnfF5raLZoAJrkks7SkWgE= =sjai -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
