SOAPAction is required in SOAP 1 1 but can be empty         See https   www w3 org TR 2000 NOTE-SOAP-20000508   Toc478383528   The header field value of empty string      means that the intent of the SOAP message is provided by the HTTP Request-URI    Try setting SOAPAction

If its a SOAP 1 1 service then you will also need to include a SOAPAction HTTP header field   http   www w3 org TR 2000 NOTE-SOAP-20000508   Toc478383528

When soapAction is missing in the SOAP 1 2 request  and many clients do not set it  even when it is specified in WSDL   some app servers  eg  jboss  infer the  actual  soapAction from  xsd import namespace   wsdl operation name   So  to make the inferred  actual  soapAction match the expected soapAction  you can set the expected soapAction to  xsd import namespace   wsdl operation name  in your WS definition   WebMethod action      for Java EE   Eg  for a typical Java EE case  this helps  not the Stewart s case  National Rail WS has  soapAction  set     WebMethod action    http   packagename of your webservice class com methodName    If you cannot change the server  you will have to force client to fill soapAction

We put together Web Services on Windows Server and were trying to connect with PHP on Apache   We got the same error   The issue ended up being different versions of the Soap client on the different servers   Matching the SOAP versions in the options on both servers solved the issue in our case

I have come across exactly the same problem when trying to write a client for the National Rail SOAP service with Perl   The problem was caused because the Perl module that I m using  SOAP  Lite  inserts a     in the SOAPAction header      SOAPAction   http   thalesgroup com RTTI 2008-02-20 ldb  GetDepartureBoard    This is not interpreted correctly by  NET servers  I found this out from Example 3-19 in O Reilly s Programming Web Services with SOAP   The solution was given below in section 3-20  namely you need to explicitly specify the format of the header with the  on action  method   print SOAP  Lite   - gt  uri  urn Example1     - gt  on action sub sprintf   s  s           - gt  proxy  http   localhost 8080 helloworld example1 asmx     - gt  sayHello  name    - gt  result     n n     My guess is that soapclient com is using SOAP  Lite behind the scenes and so are hitting the same problem when talking to National Rail    The solution is to write your own client so that you have control over the format of the SOAPAction header     but you ve probably done that already
