XJC in Apache Ant

Due to some reason I cannot define a new XJC task via

<taskdef name="xjc" classname="com.sun.tools.xjc.XJCTask">
    <classpath>
        <fileset dir="${lib.dir}" />
    </classpath>
</taskdef>

Lucky! I found a workaround:

<target name="xjc">
    <exec executable="xjc">
        <arg value="-d" />
        <arg value="${xjc.dir}" />
        <arg value="${schema.dir}" />
    </exec>
</target>

It fits my needs!
