Hi Antoine,

Thanks for your reply.

The "base.path" defined is as given below
    <path id="base.path">
      <dirset dir="${prd.classes}"/>
      <dirset dir="${src}/../tmp/cs/www/classpath"/>
        <!-- sdk classes -->
      <fileset dir="${prd.lib}">
          <include name="**/*.jar"/>
      </fileset>
        <!-- Third part libraries -->
      <fileset dir="${prd.lib.thirdparty}">
          <include name="**/*.jar"/>
      </fileset>
        <!-- JRE libraries -->
      <fileset dir="${env.JAVA_HOME}/jre/lib">
          <include name="**/*.jar"/>
      </fileset>
    </path>

 Please suggest me what should I have to do?


Thanks,
_Vino
