Grouper Developers Forum

[Chris Hyzer <>]

Btw, I assume you are referring to the web.xml and the UI... the grouper web 
service webapp also has a web.xml...  and since it isn't struts it is a 
little different.

I added more information to that section of the wiki.  Do you have specific 
questions?

https://wiki.internet2.edu/confluence/display/GrouperWG/Customising+the+Grouper+UI#CustomisingtheGrouperUI-web.xml

A web application web.xml file is a key configuration file and any site 
wishing to customise the Grouper UI will need to modify it.  The web.xml is a 
J2EE deployment descriptor which configures the Servlets (how URLs are mapped 
to Java classes), the filters (pre/post logic around servlets), j2ee security 
(if not done in apache or somewhere else), listeners (for j2ee events), 
custom tag libraries (how some tags in JSPs map to java classes), etc.  
Things you might need to customize are filters (e.g. a new way to do 
authentication / authorization), security (do you want the servlet container 
to manage authentication / authorization?), custom tag libraries (are you 
using a new library in JSP extensions?), etc.
