[Geoserver-devel] Read-only feature determination

In trying to test the DB2 transaction support in GeoServer, I'm getting a message like "feature COUNTIES is read-only" but it isn't obvious what GeoServer is looking at to make this determination? I've looked at the Java trace and the various datastore/feature definition XML files but don't see anything obvious.

What is GeoServer looking for?

Normally it makes this call based on if the DataStore returns a FeatureSource or FeatureStore implementation.
