Question

How does the Java Web ADF handle cached ArcGIS Server services that have been added to the map?

Answer

The Java Web Application Developer Framework (ADF) allows multiple resources to be added to the map that is displayed in the browser. Any combination of ArcIMS, ArcGIS Server, Web Map Server (WMS), and ArcWeb services can be added to the map. When dealing with ArcGIS Server services, the Java Web ADF differentiates between those that have generated map cache and those that have not generated map cache. In all cases the cache is used. Of the two scenarios below, the first generally runs slower.

1. If the cached ArcGIS Server service is above a layer that does not have cache, then it asks the MapServer server object container (SOC) for that resource and the MapServer uses the cache in generating an image.

2. In all other situations the Java Web ADF retrieves the cache directly or accesses it through the cache tile handler.
