I'm working with a set of webapps running on Tomcat 6.0.20 that use java.util.logging (aka JDK1.4 Logging) for legacy reasons. Since the webapps each have their own logging configuration, I followed the instructions on the Tomcat logging page ( http://tomcat.apache.org/tomcat-6.0-doc/logging.html) and started using ClassLoaderLogManager. Things work great at startup, but we have some code that modifies the logging.properties file for a webapp and then calls LogManager.getLogManager().readConfiguration(), expecting that to reload the file. Neither that method nor the readConfiguration(InputStream) version seem to have any effect, but the changes to the file work if I restart Tomcat. Any suggestions? Does it sound like I'm doing something wrong or missing a step? Thanks, Matt
