Filtering with Maven 2

[Dhruva Reddy]

I am working with a Java web application and trying to filter resources for 
inclusion in the WAR file.  This application runs in Tomcat.

There is one file in particular, context.xml, which resides in 
src/main/webapp/META-INF/context.xml.  I have the following in pom.xml:

<build>
  ...
  <filters>
    <filter>${user.home}/.m2/container.properties</filter>
  </filters>
  <resources>
    <resource>
      <directory>src/main/webapp</directory>
      <filtering>true</filtering>
    </resource>
  </resources>
  ...

Without the above, the WAR contains META-INF/context.xml, as is necessary.  
However, when I have filtering turned on as above, I find the following in the 
WAR:

META-INF/context.xml (this copy is not filtered)
WEB-INF/classes/META-INF/context.xml (this copy is filtered as expected, but of 
course the file is in the wrong place)

I am using Maven 2.0.8.  Is it possible to filter this way, or is there 
something else I need to do for WAR files (like look at the WAR plugin)?

Thanks,
Dhruva
