Re: [jetty-users] Jetty provides HttpService API ?

[Cristiano Gavião <cvgaviao@xxxxxxxxx>]

Hey Hugues,

When I heard about web-bundle I just think:  if in the web.xml there is 
a listener session and jetty reads it, so probably it should create 
those listeners programmatically somehow... :)

My need of a Servlet ContextListener setup was because I'm trying to 
integrate apache shiro security in my application and it needs to setup 
a filter and a listener. I could extend the vaadin-osgi add-on to use 
ExtendedHttpService and setup the filter, but couldn't find a way to 
provide a listener...

My knowledge in such subject is not that much, but I think that I figure 
out your tip, thanks...

regards,

Cristiano
