I cannot make ant to run a simple xdoclet task.
I can't find whats wrong:

...
    <target name="ejbdoclet"
               depends="init"
               description="generates ejb classes">

        <taskdef name="ejbdoclet"
            classname="xdoclet.ejb.EjbDocletTask"
      classpath=".;C:/java/eclipse3m2/plugins/org.jboss.ide.eclipse.xdoclet.core_1.2.0/xdoclet-ejb-module-1.2b3-dev.jar">
        </taskdef>
       
        <ejbdoclet sourcepath="${dest.dir}"
                  destdir="${dest.dir}"
                  ejbspec="2.0">
   
        </ejbdoclet>

    </target>

I get:

BUILD FAILED
file:C:/java/eclipse3m2/workspace/tutorial/build.xml:13: taskdef class
xdoclet.ejb.EjbDocletTask cannot be found

The file is there and it contains the task.
Whats wrong?
