cas proxy configuration

[Edward Chen]

I am going to install CAS 2. I browsed
http://www.yale.edu/tp/auth/cas20.html for the following code. But I
don't know where I insert the following code to. go to cas's web.xml or
deployerConfigContext.xml or application's web.xml?????

  <cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'>
    <cas:authenticationFailure code="...">
	*/Optional authentication failure message/*
    </cas:authenticationFailure>
  </cas:serviceResponse>

On success, the document node contains a subelement with its own
marked-up content:

  <cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'>
    <cas:authenticationSuccess>
	<cas:user>*/NetID/*</cas:user>
    </cas:authenticationSuccess>
  </cas:serviceResponse>
