[udig-devel] Workaround for UDIG-909

[Mark Presling <mark@xxxxxxxxxxxx>]

Hi all,

As a workaround for UDIG-909 I have decided to create my own 
WFSDataStore to query for features. I do this by reading the URL from 
the WFS layer that I want to query and creating a new WFSDataStore using 
the following code:

           FeatureSource origFeatureSource = layer.getResource(FeatureSource.class, null);
           
           WFSDataStoreFactory fact = new WFSDataStoreFactory();
           java.util.Map params = new HashMap();
           params.put(fact.URL.key, layer.getGeoResource().getIdentifier());
           params.put(fact.PROTOCOL.key, Boolean.TRUE);
           params.put(fact.TIMEOUT.key, new Integer(6000));
           
           DataStore ds = fact.createNewDataStore(params);
           FeatureSource featureSource = ds.getFeatureSource(origFeatureSource.getSchema().getTypeName());
           
           logger.info("Searching for features using query: " + newQuery.toString());
           FeatureCollection results = featureSource.getFeatures(newQuery);


This works well, but I'm convinced there must be a better way of 
retrieving the WFS parameters from the existing datastore, or even that 
there may be some sort of Util class floating around that can clone 
DataStores.

Any ideas?

Thanks,
Mark
