Ant build file 4 OJB:ojbdoclet fileset dir refer to an jar file (or jar in classpath) - JDBC JAVA

Hi, i've created this Ant build file for OJB Project:

Code:

<project name="OJB" default="init-db" basedir="..">

      <target name="repository-files">
          <property file="./lib/build.properties"/>
          <taskdef name="ojbdoclet"
            classname="xdoclet.modules.ojb.OjbDocletTask"
            classpathref="build-classpath">
          </taskdef>
          <ojbdoclet destdir="./ojb">
              <fileset dir="./src"/>
              <ojbrepository destinationFile="repository_user.xml"/>
              <torqueschema databaseName="${torque.database.name}" destinationFile="project-schema.xml"/>
          </ojbdoclet>
      </target>
      
<target name="init-db" depends="repository-files">
    <!-- Torque's build file -->
    <property name="torque.buildFile"
              value="lib/build-torque.xml"/>
............
............
............

and it works fine!! it generate all necessary code and it generate correctly all annotated classes's db tables on <fileset dir="./src"/>.

But, if i generate a .jar including a class annotated with OJB comments and i include it in my project classpath, how i can set the "fileset dir" to permit at ANT to read the annotated class on .jar file??

Thanks,
Mirko
