You're right about Parameter/context-param but I'm not sure all
standards conforming servlet containers are guaranteed to provide an
'external override' behaviour.
If the resource entry in web.xml is insufficient to fully configure the
resource, they'll have to provide some form of mechanism for this.
You might also want to read:
http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html#web.xml_configuration
and

I got it to work by removing the env-entry from web.xml.
You have to add override=false to your Environment element. It is
tricky, but it is documented
http://tomcat.apache.org/tomcat-6.0-doc/config/context.html#Environment_Entries
BTW, I think Parameter (context-param in web.xml) are easier to
use. Note that it requires override=false as well.

Why not do your initialisation in the Servlet.init() method?

Hello,

RE: [tomcat-6.0.33] META-INF/context.xml Environment not working
I got it to work by removing the env-entry from web.xml. I believe
this is a regression because it works correctly under 5.5.17. Under
5.5.17 it finds the env entry with or without having defined in web.xml.
Under 6.0.33 having the env entry defined in web.xml *prevents* it from
finding it.
