How To Instantiate a EnvelopeEditorFactory/EnvelopeEditor??

[Andrew Yang <An...@Sun.COM>]

I tried to create an instance of EnvelopeEditorFactory (from which I can create an instance of EnvelopeEditor) by:

------------------------------------
try
{
   Class aClass = Class.forName("org.apache.soap.transport.EnvelopeEditorFactory");
   EnvelopeEditorFactory factory = (EnvelopeEditorFactory)aClass.newInstance();
   Properties props = new Properties();
   props.put("EnvelopeEditorFactory",
          "org.apache.soap.transport.EnvelopeEditorFactory");
   EnvelopeEditor editor = factory.create(props);
}
catch(Exception e)
{
   ...
}
------------------------------------

An exception is thrown that complains 
   "Cannot instantiate class: org.apache.soap.transport.EnvelopeEditorFactory"

Do you have any ideas? How should I create an EnvelopeEditor instance? 

Thanks in advance!
