Can you share your pom, the command you use to run, and any shiro integration code? My first guess would be that you need slf4j libs on your classpath.
Thanks, Jared James Whetstone <[email protected]> wrote: I've built an example web app using maven that is dying during initialization and I can't figure out how to address the error. I'm using jetty 7.4.2 and Shiro 1.1.0. My example app is using jetty embedded.
