Subject cvs commit: xml-axis/java/samples/stock GetQuote2.java
Date Wed, 28 Aug 2002 19:25:10 GMT
dug         2002/08/28 12:25:10

  Added:       java/samples/stock GetQuote2.java
  Log:
  (forgot a file)
  
  Add a Java Transport/Binding.
  This will allow people to switch between native Java calls and SOAP
  calls by just switching the WSDL, Port or URL.  The URL is assumed
  to be of the form:   java:<classname>    ie. java:org.apache.Foo
  This does call all of the client-side chains but since it does not
  create a server object it does not call the server side chains.
  If you want that then you can use the Local Transport.
  This isn't 100% there yet - for example this only handles RPC for now.
  Stubbed in code for Msg but i'm running into problems with the Op.Desc.
  stuff.
