[weld-issues] [JBoss JIRA] (WELD-718) register Weld Servlet listener in web fragment

Fri, 12 Jul 2013 04:56:31 -0700

Martin Kouba commented on Feature Request WELD-718

I don't think using web-fragment.xml will help a lot.

Right now Weld implements two listeners:

  • WeldListener/WeldInitialListener should always be registered as the first listener, before any other (application) listeners
  • WeldTerminalListener should always be the last registered listener (see also WELD-1269)

So basically there are two major issues:

  • Listeners defined in web.xml must be always processed before any of the web-fragments
  • There can only be one <ordering> element in a web-fragment.xml, so that it's not possible to satisfy both requirements (first and last listener)

See also the Servlet spec "8.2.2 Ordering of web.xml and web-fragment.xml".
