maven-war-plugin error /

[Marco Mistroni <mm...@gmail.com>]

hi all
 i m experiencing some errors with Maven2 war plugin
situationis like this

i am trying to use maven2 with an existing project (developed in RAD)
heres' the project structure

webProject
  |---- JavaSource
     |--------com ...
     |--------mw
          |___resources
             |____ appresources.properties
          |___configurations
             |____ myPopulator.xml
  |___ WebContent
     |__ WEB-INF
     ...misc jsp files

now, my problem is that , in the mw directory,  the   'resources' directory
files should go under  WEB-INF\classes and the
      configurations/myPopulator.xml should go under WEB-INF
i m tyring to use maven2 filtering, i want to avoid use ant tasks..
here's the excerpt

<plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-war-plugin</artifactId>
          <configuration>
        <warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
        <webResources>
           <resource>
                 <directory>${basedir}/JavaSource/ngenmw</directory>
                 <excludes>
                    <exclude>**/dataSourcePopulator.xml</exclude>
                 </excludes>
           </resource>
           <resource>

<directory>${basedir}/JavaSource/ngenmw/configurations</directory>
                 <targetPath>WEB-INF</targetPath>
                 <filtering>true</filtering>
           </resource>
        </webResources>
          </configuration>
  </plugin>

according ot docs of maven war plugin, i can do the above... but when i
launch mvn it results in the following exception

[INFO] Executed tasks
