    Description

      I'm using the xjc ant task to generate the java classes for a DTD file but i'm getting this error when running the task:

      I've configured the ant task like this:

      <target name="generate.java">
      <xjc schema="src/main/dtd/Tapestry_4_0.dtd" target="${output.dir}">
      <dtd/>
      </xjc>
      </target>

      I'm attaching the DTD file.

      Thanks.
