Invalid multiple configuration file warning -------------------------------------------
Key: LBCLASSIC-159 URL: http://jira.qos.ch/browse/LBCLASSIC-159 Project: logback-classic Issue Type: Bug Components: Other Affects Versions: 0.917 Environment: Resin webapp Reporter: Hontvári József Assignee: Logback dev list
I receive strange warnings in the status info. It says that logback.xml, which in this case comes from a file and not from the classpath, occurs multiple times. The file is specifies and logged using absolute path, so even relative paths cannot cause the warning. Logback configuration file is specified by the system property "logback.configurationFile". It is done by the Resin application server, somehow it is able to supply different properties for different web applications. I don't think this is important, however. Maybe I am doing something wrong, but at least the message doesn't help. 20:36:34,236 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [file:/C:/Progra~1/mireka/conf/logback.xml] at [file:/C:/Progra~1/mireka/conf/logback.xml] 20:36:34,236 |-WARN in ch.qos.logback.classic.LoggerContext[default] - Resource [file:/C:/Progra~1/mireka/conf/logback.xml] occurs multiple times on the classpath. 20:36:34,236 |-WARN in ch.qos.logback.classic.LoggerContext[default] - Resource [file:/C:/Progra~1/mireka/conf/logback.xml] occurs at [file:/C:/Progra~1/mireka/conf/logback.xml] 20:36:34,236 |-WARN in ch.qos.logback.classic.LoggerContext[default] - Resource [file:/C:/Progra~1/mireka/conf/logback.xml] occurs at [file:/C:/Progra~1/mireka/conf/logback.xml] 20:36:34,236 |-WARN in ch.qos.logback.classic.LoggerContext[default] - Resource [file:/C:/Progra~1/mireka/conf/logback.xml] occurs at [file:/C:/Progra~1/mireka/conf/logback.xml]
