Dods: Null pointer exception in taskdef

In ant with task def I get the following.

relevant lines in build.xml are...


    <taskdef name="dods" classname="org.enhydra.ant.taskdefs.Dods" 
classpathref="xmlc.classpath"/>
    ...

    <!-- ========================================================= -->
    <!-- DODS: generate database manuplation java class            -->
    <!-- ========================================================= -->
    <target name="dods" depends="prepare" if="dods.doml">
        <dods domlFile="${dir.project}/${dods.doml}"
                    outputDir="${dodsbuild.dir}"
                    action="dods:java"
                    templateset="standard"/>
        <copy todir="${dir.classes}">
           <fileset dir="${dodsbuild.dir}/classes" />
        </copy>
    </target>

The error is...

Any ideas?
