Hi Guys,

  First of all I have to admit that I am pretty new to this mono
  world. My problem is the following: I have a Web Service developed
  under VS2003 and it works fine on a Windows server with IIS. I have
  deployed this WS on a Linux machine that runs Apache and Mono, but
  when I try to invoke one of its methods I always get a

  "System.Web.Services.Protocols.SoapHeaderException: Object reference
   not set to an instance of an object"

   What is the problem with? Can anyone help me to find the solution?

Thanks in advance!
Peter Neumann
