Is there a way to draw (and reproject) a gradicule with the WMS....short of
creating a feature dataset the mimics a gradicule?

Thanks Again,
Steve

No, but there is some code that might get you started. It'd be great if we could just add a graticule layer in, and I think the basics are done, but no integration to geoserver. There's a JIRA at: http://jira.codehaus.org/browse/GEOT-600 that has the code to do it, and a user on the list included a sample on how to use it:

Here its the code for using the module:

          MapLayer ml = null;

         GraticuleFeatureCollection gfc = null;

         try
         {
             Groperties g = new
Groperties("org/geotools/graticule/graticule-spacer.properties");
             GraticuleSpacer gs = new
GraticuleSpacer(org.geotools.referencing.crs.DefaultGeographicCRS.WGS84, new
GraticuleSpacer.DdmSpacings(g).getSpacings());
             gfc = new GraticuleFeatureCollection(gs);
             gfc.setViewport(envelope);
             gfc.setDeviceSpace(rectangle);
             ml = new DefaultMapLayer(gfc.collection(), style);
             gfc = null;
             gs = null;
             g = null;
         }
         catch(Exception ex)
         {
             ex.printStackTrace();
         }

If you're interesting in integrating in to GeoServer let me know and I'll think on how we should go about doing so...

Using Tomcat but need to do more? Need to support web services, security?
