/** | |
* QMan resource metadata exchange. | |
* We cannot resuse the preexisting classes directly because the wsdl of the service instance | |
* is retrieved using a file path. | |
* Since the owner resource (QManWsResource) is dynamic (I mean, its interface is dynamic), the corresponding | |
* WSDL cannot defined at compile time but needs some changes when the resource is created. | |
* As part of that, the WSDL template found under wsdl folder is modified with the additional properties of the given | |
* resource. The metadata exchange capability must include those properties too. | |
* | |
* Note that this capability is appliable only to a QManWsResource. | |
