CAS Client Integration Instructions

[Marvin Addison]

I wrote up some instructions based on 
http://www.ja-sig.org/products/cas/client/client-java/index.html.  A 
developer on another team just tried following them today, and ran into 
problems.  I took the Spring XML from that page verbatim, and our 
experience today suggests it is broken in at least a couple of ways:

1) The beans namespace declarations didn't work for us
2) There is no constructor for Cas20ProxyTicketValidator that takes 6 
arguments in the 3.0.0 client download.

Studying the source and trial and error allowed us to correct what 
appeared to be wrong, and we got a working configuration.  I'm curious, 
however, about the instructions I started from.  Has 
acas at tp.its.yale.edunyone followed those instructions with success?  Are 
there other instructions that are more current?  If not, I'd be happy to 
document what worked for us if someone could point to a spot.

Tangentially, reading the Spring XML in those instructions reminded me 
of other Spring XML configuration files I've studied in the CAS 
distribution.  I have a general recommendation:  for beans that have 
multiple argument constructors, provide comments above each one with at 
least the data type and name of the argument.  I've had to correlate 
with source on more than one occasion trying to figure out which 
constructor argument went to what property, and such comments would have 
saved me the trouble 9 out of 10 times.
