Hi Anne,
Thanks for your response.I am attaching with this mail the HelloWorld
Service and axis2 client.Its a simple HelloWorld service and I am using end
point reference to access this service.There is no wsdl for it.Kind Regards Kashif Saleem -----Original Message----- From: Anne Thomas Manes [mailto:[EMAIL PROTECTED] Sent: Sat 3/25/2006 3:45 PM To: [email protected] Subject: Re: problem in accessing python Hello World Service Please post the WSDL. Based on the error messages, I'm guessing that the server is not expecting the <example1:HelloWorld xmlns:example1="http://example1.org/example1";> element to appear in the message.
