org.geoserver.platform.GeoServerResourceLoader

GeoServerResourceLoader
public class GeoServerResourceLoader extends DefaultResourceLoader (Code)
Manages resources in GeoServer.

The loader maintains a search path in which it will use to look up resources. The GeoServerResourceLoader.baseDirectory is a member of this path.

Files and directories created by the resource loader are made relative to GeoServerResourceLoader.baseDirectory .

 
 File dataDirectory = ...
 GeoServerResourceLoader loader = new GeoServerResourceLoader( dataDirectory );
 loader.addSearchLocation( new File( "/WEB-INF/" ) );
 loader.addSearchLocation( new File( "/data" ) );
 ...
 File catalog = loader.find( "catalog.xml" );
