[OpenLayers-Users] Newbie: accessing Arcweb data

[Richard Duivenvoorde]

Hi Stewart,
I'm not familiar with Arcwebservices, what kind of url's are you talking 
about? Can you give an example?

Openlayers implements different kind of 'layers' for different kinds of 
datasources. Some examples of current datasources: OGC-WMS, OGC-WFS, 
Minnesota Mapserver, TMS, Google Maps, Virtual Earth, GML, KML, geoRSS 
etc etc.
If you can make your webservice talk one of those 'dialects', it should 
be possible to use Openlayers as a client for your service. If your 
service uses a different protocol/standard, it's not trivial to 
implement it.

In the examples directory
http://www.openlayers.org/dev/examples/
you can find some examples with different 'datasources', eg:
http://www.openlayers.org/dev/examples/multiserver.html

I think HTTPRequest is meant to be a base class for other layers which 
use http-request: Grid extents HTTPRequest, WMS extends Grid etc.

Regards,
Richard Duivenvoorde
