For example, for the log config, use this in web.xml:
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>${log4j.configLocation}</param-value>
</context-param>
<context-param>
<param-name>log4jRefreshInterval</param-name>
<param-value>15000</param-value>
</context-param>
<context-param>
<param-name>log4jExposeWebAppRoot</param-name>
<param-value>false</param-value>
</context-param>
Then execute your server with
-Dlog4j.configLocation=~/.myconfig/log4j.xml. Include another
log4j.xml in the deployed application, just in case (it will be
applied if the overriden location was not found).
With spring you can also <import location="${mail.location}"/>, which
works with -d properties.
This is the spring solution, but most probably you can arrange
something similar with JEE or Guice. I think Grails is shipped with
something similar.
