Loading a custom WSDL for Axis2 Service

There are cases where we have to go with Contract First Approach when implementing Axis2 services. In such a case we will have a WSDL that we want to expose via the service rather than allowing the engine to generate one.
This can be done by setting useOrignalWSDL parameter to true in services.xml as below.

<parameter name="useOrignalWSDL">true</parameter>

But there are some musts that we should do to load the given WSDL.

1. We have to make sure that our WSDL file is inside META-INF folder.
2. We should make sure that the same service name is used in both the WSDL and the services.xml
ex:
In WSDL
<wsdl:service name="MyService">

In services.xml
<serviceGroup>
        <service name="MyService">
        ....
        </service>
      </serviceGroup>
3. We should name the WSDL file as service.wsdl or <service-name>.wsdl
      ex:
      If our service name is MyService the WSDL should be either service.wsdl or MyService.wsdl
4. We have to set useOrignalWSDL=true in services.xml
5. The WSDL should be valid.
