If you have several instances of Tomcat, you ought to have different
server.xml files for each instance.
You could put a <GlobalNamingParameter> entry into server.xml that
identifies the server. You can get this value out using JNDI at runtime.
The Tomcat 4.1 sample server.xml files contain an example of an Integer
value in the GlobalNamingResources:
<GlobalNamingResources>
<!-- Test entry for demonstration purposes -->
<Environment name="simpleValue" type="java.lang.Integer" value="30"/>
.
.
.
</GlobalNamingResources>
I would imagine that later versions of Tomcat (5.x) would have the same
capability, and that you could adopt this technique to suit your needs.
