Hi,
I'm not sure if this is a jetty issue or an issue with shiro, but I am
trying to use the Jetty-Maven plugin for development and one of the
key features I want is Jetty's hot redeployment when files are
changed. However, Shiro is throwing the following exception when jetty
attempts to reload the application and I am not certain what can be
done to correct this.
[Scanner-0] ERROR org.apache.shiro.web.servlet.AbstractFilter - Unable
to start Filter: [No WebEnvironment found: no
EnvironmentLoaderListener registered?].
java.lang.IllegalStateException: No WebEnvironment found: no
EnvironmentLoaderListener registered?
