In which cases does the container CHECK the web.xml

When does the container CHECK the web.xml ?

a) Will web.xml be checked when the URL has a .html at the end
b) Will web.xml be checked when the URL has a .jsp at the end

Or is it that the container always checks the web.xml whenever a URL is accessed.

The container reads the web.xml at startup. (it might also do it when the web.xml file is modified, but that's container dependant). It won't check it for every request. That would be a performance killer.

Hi Christophe,

On a related note , do you know which containers (servers) e.g. tomcat , weblogic etc supports runtime modification of web.xml and how does it actually happens do they expose JMX webpage or it simply modification using text editor.

I.e. Tomcat 7 does support web.xml (context) reload.
It was reloaded after I made some changes in external text editor.

Cheers!
