How to read JNDI resources?
Using tomcat 4.3.1 I have included the following in server.xml
<GlobalNamingResources>
<Environment name="config_file" type="java.lang.String" value="test"/>
</GlobalNamingResources>
In a servlet loaded on startup I try to read in the property
InitialContext ic = new InitialContext();
Context ctx = (Context) ic.lookup("java:comp/env");
String configFilename = (String)(ctx.lookup("config_file"));
This code throws a NamingException. Where have I gone wrong?
Thanks
Andrew

Thank you, I appreciate your reply. I didn't have a context entry so I
added a minimal one (copied from the /examples one) before proceeding
further as shown below.
<Context path="/xxx" docBase="xxx" debug="0" reloadable="true"
crossContext="true" />
Unfortunately tomcat doesn't start now. I get a 'Document base
C:\Development\Java\jakarta-tomcat-4.1.31\webapps\xxx does not exist or
is not a readable directory'
So I added a direcory xxx. Now tomcat starts ok but it doesn't unpack
the xxx.war. Again I'm probably making some very simple mistake but
can't see the problem or an answer in the docs or by googling...

You need to include a <ResourceLink> element in your context.
