Class VirtualDirContext

java.lang.Object
  extended by org.apache.naming.resources.BaseDirContext
      extended by org.apache.naming.resources.FileDirContext
          extended by org.apache.naming.resources.VirtualDirContext
All Implemented Interfaces:
javax.naming.Context, javax.naming.directory.DirContext

public class VirtualDirContext
extends FileDirContext

Extended FileDirContext implementation that will allow loading of tld files from the META-INF directory (or subdirectories) in classpath. This will fully mimic the behavior of compressed jars also when using unjarred resources. Tld files can be loaded indifferently from WEB-INF webapp dir (or subdirs) or from META-INF dir from jars available in the classpath: using this DirContext implementation you will be able to use unexpanded jars during development and to make any tld in them virtually available to the webapp. Sample context xml configuration: <Context docBase="\webapps\mydocbase"> <Resources className="org.apache.naming.resources.VirtualDirContext" virtualClasspath="\dir\classes;\somedir\somejar.jar"/> </Resources> This is not meant to be used for production. Its meant to ease development with IDE's without the need for fully republishing jars in WEB-INF/lib
