Many WAR's and one common operation

Question

Hi,

I have to modify content of many WAR start pages to add some functionality. I can't use filters to modify cause filter needs to be placed in Web Archive. The same with servlet etc. Any clue how to do this?

You could modify the global web.xml of the container. This will affect all applications:

This document defines default values for *all* web applications
loaded into this instance of Tomcat.  As each application is
deployed, this file is processed, followed by the
"/WEB-INF/web.xml" deployment descriptor from your own applications.

Alternatively you could implement a Valve which you'll install in server.xml for a specific host (which will be running all the wars).
