Error hot redeploying shiro using jetty-maven plugin
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.

Thanks for letting us know Pete! Hopefully this helps someone else
until the Jetty team can fix that feature in the 9.x release.

Alright, so I switched to version 8 of the jetty-maven-plugin and
everything is working now. It appears that jetty 9 doesn't reload
ServletContextListeners correctly at this time.
Thanks for prompting me to spend a little more time with this Les
(sometimes all it takes is a nudge) :)

Re: Error hot redeploying shiro using jetty-maven plugin
Posted by Pete Poulos <pe...@gmail.com>.
Hi Les,
Thanks for getting back to me. Your reply prompted me to dink around with
this a bit more. I just created a stub ServletContextListener to see
whether jetty calls "contextInitialized" again after it recreates the
WebEnvironment during a reload and it appears that the
ServletContextListener.contextDestroyed(ServletContextEvent) gets called,
but that ServletContextListener.contextInitialized(ServletContextEvent) is
not called again.
That being the case, I think it's safe to assume, for now, that this is a
jetty issue and not a Shiro issue. I'll be sure to post any work around I
find here in case someone else comes across this problem in the future.

Re: Error hot redeploying shiro using jetty-maven plugin
Posted by Les Hazlewood <lh...@apache.org>.
Hi Pete,
Did you figure out what was happening here?
Shiro's default web integration requires a WebEnvironment instance be
present in the ServletContext. This is referenced by the ShiroFilter at
runtime. It appears that the WebUtils.getRequiredWebEnvironment is not
finding the expected WebEnvironment instance. Perhaps Jetty is wiping out
the ServletContext and creating a new one without Shiro's knowledge?
