That suggestion fixed it. I was using 1.0.9 which I thought was the most recent. Replacing with 1.0.13 fixed the problem. From: Logback-user [mailto:logback-user-bounces@qos.ch] On Behalf Of Tony Trinh Sent: Tuesday, 22 October 2013 2:01 p.m. To: logback users list Subject: Re: [logback-user] logback receiver configuration issue The error messages in your config indicate that you're using an old version of logback that doesn't support the "receiver"/"port" elements, which were introduced in 1.0.12. Verify that your classpath is pointing to logback 1.0.12 or newer.
