Setting Environment Variable for Tomcat 6 Servlet

[Alyssa Kwan]

Hi All,

I'm using Ubuntu's default installation of Tomcat 6. I'm deploying a ROOT.war, 
and trying to set an environment variable specific to it, i.e. accessible from 
System.getenv() in the Servlet.init(config).

According to the docs 
(http://tomcat.apache.org/tomcat-6.0-doc/config/context.html), I can specify 
this in a Context element in conf/Catalina/localhost/ROOT.xml. I've created 
that with these contents:

<Context>
 <Environment name="FOO" value="bar" type="java.lang.String" override="false"/>
</Context>

And I've deployed the webapp as usual, i.e. to webapps/ROOT.war.

Server.getenv("FOO") in the Servlet.init(config) still returns null. What am I 
missing?

Thanks!
Alyssa
