I have two questions that I hope y'all can help me with. Here's a little
background on why I'm bothering y'all. We've got a bunch of java interfaces
being used via RMI, now we want to expose them via web services, too. We do our
own authentication, so I was thinking the easiest thing is to have the client
call the authentication method, and then pass the resulting authentication
token as a header arg-that way the existing java interfaces don't need to
change.
Question 1) I'm also not such a smartie about wsdl. (I'm sure you're wondering
if I'm a smartie about anything ;-) ) The WSDL for my service is below. It
works just fine with WSDL2Java, and the generated Java client stubs do just
what I want them to. However, when I Add Web Reference in .NET, it gives an
error, "the element attribute is not allowed on encoded message parts". If I
change the part specification from "<wsdl:part element="intf:authToken"
name="auth_header"/>" to "<wsdl:part type="intf:authToken"
name="auth_header"/>", it says "The datatype 'authToken' is missing.", and
WSDL2Java says the same thing. If I undo that change and change the operation
to be literal, then it says that "The combination of style=rpc with use=literal
is not supported." If I change it to style=document, it says "Unable to import
operation 'getExchangeRate'. Specified cast is not valid."
Would someone take pity on the noob and help me with my WSDL?
Question 2) I know virtually nothing about c#, but someone gave me a test
program that calls a web service. I was able to figure out how to add my web
service to the environment, and add a call to it from the little program, but
what do I do about header args? Could someone help me figure how to pass a SOAP
header argument on the call? Or will this problem be magically solved once I
can successfully import the web service? Here's the code I have:
FirstSOAPTest.CurrencyService.CurrencyWebServiceService curServ = new
FirstSOAPTest.CurrencyService.CurrencyWebServiceService();
// The value of a proper authToken is in this.textBoxAuthReturn.Text
double s = curServ.getExchangeRate();
The WSDL is what was generated by Axis, and then I added the bits about a
header arg (the parts I added are surrounded by blank lines). Here's my WSDL:
