       OK, forgive me for possibly being dense here but why is it if I
put a couple of printlns in like so:
               File dbf = new File("data/shape/zt25_d00.dbf");
               File sp = new File("data/shape/zt25_d00.shp");
               File shx = new File("data/shape/zt25_d00.shx");
               EsriLayer el=new EsriLayer("PUKE", dbf.toURL(),
sp.toURL(), shx.toURL());
               EsriGraphicList egl=el.getGeometry(sp.toURL(), shx.toURL());
               OMPoly op=(OMPoly)egl.getOMGraphicAt(326);
               System.out.println(op.getLat());
               System.out.println(op.getLon());
       The values ouputted for both lat/lon are 0? I am just trying to
get these so as to position the label.
