http://esritomcat:8080/ServiceHandler/

Test environment:
I have created the virtual directory for map server (cache) as "http://test.domain.com/arcgis/server/arcgiscache"

While running the java application i am getting in the source of the page as
EsriMapSourceTile("http://test.domain.com/arcgis/server/MapServiceName.........")
I am able to see the map tiles in the web.

QA environment.
Similarly i have given the virtual directory as "http://qa.domain.com/arcgis/server/arcgiscache"

But in the web page source i am getting "EsriMapSourceTile("http://esritomcat:8080/ServiceHandler/...." Also, it is showing the blank screen.


Solution:

Check the host file entry.. there should be an entry of qa.domain.com in the host file.. (c:\windows\systesm32\drivers\etc)
