I do this in the Ant build by filtering the properties file when you 
build the .war file or copy to the webapps directory.

Here's an example from my build.xml:

     <!-- Copy any resource or configuration files -->
     <target name="resources">
         <filter token="TOMCATHOME" value="${tomcat.home}"/>
         <filter token="TESTHOST" value="${test.host}"/>
         <filter token="SOAPHOST" value="${soap.host}"/>
         <copy todir="WEB-INF/classes" includeEmptyDirs="no" 
filtering="true">
             <fileset dir="WEB-INF/src">
             <patternset>
                 <include name="**/*.conf"/>
                 <include name="**/*.properties"/>
                 <include name="**/*.xml"/>
             </patternset>
             </fileset>
         </copy>
     </target>

And in the properties file:

# Host name part of SOAP server URL
soap.server:@SOAPHOST@

etc.
