title: Java equivalent of OpenLayers
body: <p>I am looking for a Java library to display map data from various sources, including shapefile, WMS, WFS, Google Maps, possibly ArcIMS, etc. It seems like OpenLayers is the closest thing to what I want, except it's a JavaScript library, and I'm writing a Swing application.</p>
  
  <p>GDAL looks promising, but as far as I can tell there won't be Java bindings until "sometime" in the future.</p>
  
  <p>Just to be clear, I am looking for a single Java API that I can use to display maps from a number of map servers/sources.</p>
  
  <p>Does anyone know if anything like this exists, and if not, where to go from here? Should I build this API on top of GeoTools? Or...</p>
