Re: [Gwt-openlayers-users] Fwd: OpenStreetMap in gwt-OpenLayers

[Jon B. <man...@go...>]

I use OSM and gwt-openlayers successfully using the following code.  This is
for the Mapnik rendering but the same can be done for Osmarender.  I don't
think I needed to download anything extra to do this, it just worked out of
the box.

MapOptions defaultMapOptions = new MapOptions();
defaultMapOptions.setControls(new JObjectArray(new JSObject[] {}));
defaultMapOptions.setProjection("EPSG:900913");
defaultMapOptions.setDisplayProjection(new Projection("EPSG:4326"));
defaultMapOptions.setMaxExtent(new
Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34));
defaultMapOptions.setNumZoomLevels(19);
defaultMapOptions.setUnits("m");

MapWidget mw = new MapWidget("100%", "100%", defaultMapOptions);
 mw.getMap().addLayer(OSM.Mapnik("Mapnik"));

Obviously, the key line is the last line :-)
