I'm just noodling - haven't tried this. Your mileage may vary, void where prohibited, etc., etc., etc. How about: 1. use Parameter in context.xml to set the logging level: <Parameter name="LoggingLevel" value="DEBUG" override="false"/> 2. Write a servlet context listener to read the parameter 3. Set the logging level accordingly Place the servlet context listener as the first one in your web.xml so the new logging level is set before any other logging occurs. This way your log4j.xml doesn't have to change, and you can just use an appropriate $CATALINA_BASE/conf/Catalina/[hostname]/[appname].xml to set the desired logging level. This seems as if it should work. . . . just my two cents /mde/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (MingW32) iQEcBAEBAgAGBQJUEHZvAAoJEEFGbsYNeTwte+YH/12yWANWhJ2+6MwCKHkdWh5G AQi20L9LVdjTtWYx+vpZvktqiDSNvYAUTTx2+AJaolo9puqsaSLf5kfR1hTgbGy8 sMrBPLbJY1qY4uZruK5ISPc1I3nbo2j/uDtSpClbfMSGKLUIqcISiCxYwwcb/u5f UUGXSorSddwCEE2i5Sk8wHpYMcEjRDXa99t6qR5I4Xe6Tb9KG8rJ9yfiB1//snwO bOGmroKgYRB1sz7cM2xffZNW+3GzN/Z8py0GqdR07+sEDMTYpvVcW0Iu1ebmUtU6 Aw2QTcK9pu4kU+Q2DA7vOycXTdG/8XgFOnQCvhXWRvy63iR1pXiz6KNCZ6qBkrk= =nU9F -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
