How to perform Ant path mapping in a 'war' task?

I have several JAR file pattern sets, like

<patternset id="common.jars">
 <include name="external/castor-1.1.jar" />
 <include name="external/commons-logging-1.2.6.jar" />
 <include name="external/itext-2.0.4.jar" />
     ...
</patternset>

I also have a 'war' task containing a lib element:

<lib dir="${src.dir}/jars">
  <patternset refid="common.jars"/>
  <patternset refid="web.jars"/>
     ...
</lib>

Like this however, I end up with WEB-INF/lib containing the subdirectories from my patterns:

WEB-INF/lib/external/castor-1.1.jar
WEB-INF/lib/external/...

Is there any way to flatten this, so the JAR files appear at the top-level under WEB-INF/lib, regardless of the directories specified in the patterns? I looked at mapper but it seems you cannot use them inside lib.

I was dissatisfied with having to manually generate a WAR directory or declare library subdirectories, so I came up with this. Seems to work, obviously you'll need to adjust it to your own needs:

<war destfile="build/output.war" webxml="${web.dir}/WEB-INF/web.xml">
    <fileset dir="${web.dir}" />
    <mappedresources>
        <fileset dir="${lib.dir}" includes="**/*.jar" />
        <chainedmapper>
            <flattenmapper/>
            <globmapper from="*.jar" to="WEB-INF/lib/*.jar" />
        </chainedmapper>
    </mappedresources>
</war>

You can try to use mappedresources element (Ant 1.8+) 

<mappedresources>
  <!-- Fileset here -->
  <globmapper from="external/*.jar" to="*.jar"/>
</mappedresources>

http://ant.apache.org/manual/Types/resources.html#mappedresources

If you have a typical web project it is better to split the web-app libraries and general-purpose libraries in different folders and leave WEB-INF/lib to have only those needed at runtime. This way you'll avoid collisions and also your project will look much clearer to other developers.
