All Implemented Interfaces:
CacheLoader, org.jboss.system.Service

public class RmiDelegatingCacheLoader
extends DelegatingCacheLoader

DelegatingCacheLoader implementation which delegates to a remote (not in the same VM) TreeCache using the Java RMI mechanism. If configured via an XML configuration file, the remote TreeCache delegated to is this cacheloader's cache's coordinator. If configured programmatically, this cacheloader may delegate to any remote cache that has been appropriately bound. This CacheLoader expects three configuration properties: host, port and bindName. If the host propety is not specified, it defaults to localhost; if the port property is not specified, it defaults to 1098; if the bindName property is not specified, it defaults to the cacheloader's cache's cluster name.
