You can check that the Web Extensions are correctly set up. If your application development language is PHP, go to this URL in a web browser:
http://localhost:8008/mapserver2015/mapviewerajax/ajaxviewer.php?WEBLAYOUT=Library://ATest.WebLayout (Apache) or http://localhost/mapserver2015/mapviewerajax/ajaxviewer.php?WEBLAYOUT=Library://ATest.WebLayout (IIS)
If your application development language is ASP.NET, go to this URL in a web browser:
http://localhost/mapserver2015/mapviewerajax/ajaxviewer.asp?WEBLAYOUT=Library:/ATest.WebLayout
If your application development language is JSP, go to this URL in a web browser:
http://localhost:8008/mapserver2015/mapviewerajax/ajaxviewer.jsp?WEBLAYOUT=Library://ATest.WebLayout
Because the web layout ATest does not exist in the Infrastructure Map Server repository, you should see the following error:
Resource was not found: Library://ATest.WebLayout
This error is returned by the AJAX Viewer script. This shows that the Web Server Extensions are correctly enabled to receive and process requests.
