Create a WebCtxLoader given the ENC scoping class loader.

Parameters:

encLoader -

 public  void addLifecycleListener(LifecycleListener listener) 
{

}

 public  void addPropertyChangeListener(PropertyChangeListener listener) 
{

}

 public  void addRepository(String repository) 
{
      if( repositories.contains(repository) == true )
         return;
      repositories.add(repository);
      setClassPath();
}

 public LifecycleListener[] findLifecycleListeners() 
{
      return new LifecycleListener[0];
}

 public String[] findRepositories() 
{
      String[] tmp = new String[repositories.size()];
      repositories.toArray(tmp);
      return tmp;
}

 public ClassLoader getClassLoader() 
{
      return ctxLoader;
}

We must pass the wrapped encLoader as tomcat needs to see a unique class loader that is distinct from the thread context class loader seen to be in effect when the web app is started. This is due to how it binds contexts using the DirContextURLStreamHandler class.
