org.apache.naming.resources
Class DirContextURLConnection

java.lang.Object
  extended by java.net.URLConnection
      extended by org.apache.naming.resources.DirContextURLConnection

public class DirContextURLConnection
extends java.net.URLConnection

Connection to a JNDI directory context.

Note: All the object attribute names are the WebDAV names, not the HTTP names, so this class overrides some methods from URLConnection to do the queries using the right names. Content handler is also not used; the content is directly returned.
