Re: [Geotools-gt2-users] How to load a WCS capabilities document

[Justin D. <jde...@op...>]

Hi Jon,

If you have implemented the bindings correct, what you should get back 
from the parser should be the parsed capabilities document as an EMF object.

If you look at the WFS datastore you will notice it does this with the 
1.1 version of the protocol. Take a look at:

http://svn.osgeo.org/geotools/branches/2.5.x/modules/plugin/wfs/src/main/java/org/geotools/data/wfs/v1_1_0/WFS_1_1_0_Protocol.java

At the parseCapabilities() method.

Given that I've got bindings ready etc (which I haven't yet, still trying to figure that out) how do I go from my WCS1_1_1.GetCapsRequest (based on the WMS equivalent) to a response containing the capabilities document?  I've implemented the createResponse method, which creates a WCSGetCapabilitiesResponse which currently has an empty constructor.

I haven't seen the Schema class mentioned in any of the XML documentation so don't know how this is generated and/or used.  WFS on the other hand is treated as a DataStore, so I assume I can't really use that as a guide.  In either case, I can't find how making a request links with all the binding stuff.  There's a missing step in my understanding.
