How can I bring into JOSM a Esri Map Service?
For example:
http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer
Googling around I found How can I create an adapter between the ArcGIS REST interface and WMS or TMS? but what if the Esri map service does not have WMS or TMS enabled?
