Class JWSClassLoader

java.lang.Object
  java.lang.ClassLoader
      org.apache.axis.utils.JWSClassLoader

public class JWSClassLoader
extends ClassLoader

Class loader for JWS files. There is one of these per JWS class, and we keep a static Hashtable of them, indexed by class name. When we want to reload a JWS, we replace the ClassLoader for that class and let the old one get GC'ed.

Author:: Glen Daniels (gdaniels@apache.org), Doug Davis (dug@us.ibm.com)
