Hi, It seems like there is no built in support for logging from within an Eclipse RCP plug-in. So I wrote my own appender and pointed to it from my logback.xml 14:14:04,992 |-ERROR in ch.qos.logback.core.joran.action.AppenderAction - Could not create an Appender of type [foo.RCPAppender]. ch.qos.logback.core.util.DynamicClassLoadingException: Failed to instantiate type se.ericsson.baseband.logging.RCPAppender at ch.qos.logback.core.util.DynamicClassLoadingException: Failed to instantiate type foo.RCPAppender I've seen other people who have trouble with this when using ecilpse plug-ins and bundles due to different class loaders. I have however not found any proper solution to this. How would I make logback find my appender?

Is it possible to make logback log to the existnig workspace log, so that the logs show up in the "Error Log" view in the GUI? BR David
