Re: [Geoserver-users] Geoserver extension to use custom schema when crateing new data store

   Hi Norman.
   Usually in Store factories it's used an URL typed parameter to parse the 
"url" user input as we see on Shapefile one:

   public static final Param URLP =
               new Param(
                       "url", URL.class, "url to a .shp file", true, null, new 
KVP(Param.EXT, "shp"));

   Since Java URL class support only few well known protocols by default (http, 
file, jar...) you could need implement a custom handler for your new URL 
protocol in first place.
   Good old BalusC explains how to create one in this link:
   https://stackoverflow.com/a/26409796/3662679
   Now if this stuff is too much overhead and you don't need over-complicate, 
you could use a generic String typed parameter and parse/validate it
   on your factory class:

   public static final Param CUSTOM_URL =
               new Param(
                       "url", String.class, ...

   Subject [Geoserver-users] Geoserver extension to use custom schema when 
crateing new data store
   Hi,
   We developed a Geoserver extension to provide real time raster image
   data from IBM PAIRS (ibmpairs.mybluemix.net) repository.

   As part of the cleaning up of our extension, we would like to introduce a
   custom Connection schema ( "ibmpairs") specific to our plugin. This schema
   would appear and be accepted in the 'Connection' field of Geoserver's
   "create new datastore" dialog as indicated in the attached/embedded image:

   
<http://osgeo-org.1560.x6.nabble.com/file/t384375/ibmpairsschema_geoserver_create_store.png>

   Presently, we use the http schema as a workaround, Geoserver internally
   verifies the schema and URL. If I try a custom schema or url which is not
   visible the Geoserver code internally atempts to verify the Connection and
   rejects it. Somehow we need to register our new schema with Geoserver and
   get a callback to intercept this Geoserver code that verifies the new
   Connection. How do we do this?

   (Our plugin is based on public class PairsFormatFactory implements
   GridFormatFactorySpi and implements extensions of public class PairsFormat
   extends AbstractGridFormat implements Format {...} and public class
   PairsCoverageReader extends AbstractGridCoverage2DReader implements
   GridCoverage2DReader {...} and is otherwise working.
