I have a weird issue with logback configuration. My project is packet into jar files, server side and client side. Client side is run as an applet in a browser. Server side works fine, but client cannot find its configuration file (I believe so). My custom configuration doesn't work. I set log level to INFO in the configuration file logback.xml which is in the root folder of the jar, but still see DEBUG logs in Java console. Logback's internal info: 11:20:08,924 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.groovy] 11:20:08,982 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback-test.xml] 11:20:09,042 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.xml] Seems like this is somehow related with my applet, or any applet.
