What is the difference between MapObjectsJava Edition and ArcGIS Engine Java?
MapObjectsJava Edition is a collection of Java components to develop GIS applications but is much smaller in scope than the Engine API. MapObjectsJava Edition is intended for lightweight GIS applications with limited functionality. The ArcGIS Engine Java provides a much more comprehensive collection of functionality, including support for rasters, 3D visualization, the geodatabase, and usage of map documents created in ArcGIS Desktop.
