Class ContextScanningResourceProvider

java.lang.Object
  com.evermind.server.deployment.ContextScanningResourceProvider

All Implemented Interfaces:

ResourceProvider

public class ContextScanningResourceProvider
extends java.lang.Object
implements ResourceProvider

A ResourceProvider implementation that acts on a generic JNDI namespace, useful for providers who supply a namespace access mechanism. The properties are those of the namespace, save two special properties:
resource.names - An optional comma separated list of resource locations (JNDI names) that are to be exposed. Useful if the context doesnt support browsing (.list(...)).
resource.types - An optional comma separated list of resource types that are to be handled, useful if you dont want to use all the resources from the provider (for instance if hooking up to a foreign app-server's namespace and just wanting to use the JMS resources, ie ignoring DataSources).
