   * debian/rules
     - Update JAVA_HOME to correspond to default-jdk.
     - Remove unnecessary reference to ant-launcher jar file.
+    - Add DEB_ANT_BUILDFILE and set it to the build.xml in j3d-core.
+    - Remove DEB_BUILDDIR.
     - Use cvs export instead of checkout. Doesn't need user interaction.
     - Use the release tag instead of getting latest files in cvs.
       Release tag is derived from upstream version.
