This is specific to Tomcat, but Tomcat will do System variable replacement
while parsing web.xml. So you would do something like:
<init-param>
<param-name>foobar</param-name>
<param-value>${myapp.foobar}</param-value>
</init-param>
Then each of the 4 just have to include a -Dmyapp.foobar=value when starting
up Tomcat.
