The WSDL describes a Web service.
The Web service is an application that exposes an API that communicates via
It doesn't provide a browser interface.
This URL:
is called SOAPAction. It isn't an operation. It is a URL that gives the SOAP
server a hint about how to process incoming messages. You must include this
value in the SOAPAction HTTP header in your input message.

The WSDL contains a portType (an interface) called "ApplicationIdPortType"
with an operation called "GetApplicationId".
It defines a binding for that portType that supports SOAP over HTTP using
RPC/encoded format.
A service that implements that binding is available at

You must use HTTP POST to post a SOAP message to
The format of your SOAP body input message is defined by the
"ApplicationId.GetApplicationIdInput" message element.
The format of the returned SOAP body output message is defined by the
"ApplicationId.GetApplicationIdOutput" message element.

There are lots of tools available for lots of different languages to help
you build a client application.

You can find a browser tool that will invoke your service for you here:

  actually I am more of a networking guy, so thanks for your responses.
quite new to XML.

  so here is the WSDL URI  http://www.imason.com/applicationid.rem?wsdl.

  Now this is supposed to contain an ApplicationID.

  HTTP GET gives me the WSDL document in a browser.

  I perused this document to get the info. in there there is an operation
name called:

  seems to contain a query like string in Server side scripting, called

  So I type in this URL to contact the web service to return me a SOAP
message that will contain the ApplicationID.

  But I get a "Page Not Found" Message.

  so ?   any clues ?

    Vel didn't say that the "WSDL URI" was the URI for the WSDL namespace...

    If the URI is actually the URL of the WSDL file, then you can do an HTTP
GET, and you will get the WSDL document. The WSDL document is an XML
document. You can display/print it and read it. You can parse it with an XML
parser. You can navigate it with XPath. You can access and manipulate it
using a WSDL API such as JWSDL.

    What information are you looking for, and for what purpose?

      The W3C TAG [1] has an issue [2] to come up with a recommendation for
what sort of document should be served if you do an HTTP GET on an XML
Namespace URI. You might imagine that the URI could resolve to the WSDL file
itself, but since it’s an XML Namespace, there might be other documents that
are also associated with that namespace, e.g., an XML Schema.

      simple question;

      if someone has given me a WSDL URI and asked me to get an information
from it, how do I proceed ?
