Strange WSDL warning during validation in Eclispe: "wsdl:operation was not a request/response or one-way operation"

Question

I'm writing a WSDL file and I can't get rid of this warning from the Eclipse validator:

WS-I: (BP2208) wsdl:operation was not a request/response or one-way operation.

This is the WSDL source I wrote:

<?xml version="1.0" encoding="UTF-8"?>

            </input>
        </operation>
    </binding>

    <service name="MyServices">

        </port>
    </service>

</definitions>

Here you can find the complete WSDL file: https://dl.dropboxusercontent.com/u/33459047/StackOverflow/Master.wsdl

I believe that the source of the problem is the operation "updateManager", but I don't know how to fix it. Can someone help me please? Thank you in advance.

An endpoint can support 4 types of operations. From the WSDL specs:

WSDL has four transmission primitives that an endpoint can support:

• One-way. The endpoint receives a message.
• Request-response. The endpoint receives a message, and sends a correlated message.
• Solicit-response. The endpoint sends a message, and receives a correlated message.
• Notification. The endpoint sends a message.

The WS-I Profile seems to have a rule for supporting only two of them. From WS-I, Test Assertion: BP2208:

Context:
For a candidate wsdl:operation in a wsdl:portType definition

Assertion Description:
The wsdl:operation element is either a WSDL request/response or a one-way operation (no Notification or Sollicit-Response).

Failure Message:
wsdl:operation was not a request/response or one-way operation.

Your updateManager operation is a Notification and from here your warning.

Clearing the error depends on you interoperability compliance needs. You can either ignore the warning (and then your service won't be 100% interoperability compliant) or you can fix it by changing the operation type (which depends on your application).
