How do I get context-params that are set in the web.xml file?

[beeky]

I hope the subject says it all but here's a reiteration.  The sample
web.xml in TOMCAT_HOME/doc/appdev shows how to set and access
<context-params>.  The current docs on ServletContext do not seem to
have a method to get context params.  <init-params> on a per servlet
basis work as described but I have several values that all servlets must
access.

Thanks in advance,
