Problem when trying to execute web service model in WDPJ application

116 Views

Hi,

I am working on Netweaver CE 7.2. I have registered a Business Object Data Services web service into the the Service Registry.

In NWDS, I have created a Web Service model based on the WSDL imported from the SR. I imported the Web Service in the controler using the template function and have created an basic view with a button to call the service.

When I try to execute the WSDL operation, I get the following error:

Error 500:
javax.xml.rpc.ServiceException: Configured BindingData 90e45aff-04cf-4495-9a78-95db20badf99 is not compatible with those available in the Webservice clinet framework. Configured BindingData has operation Ping operations, which is not found in the Webservice client framework configuration.

Another thing is that when I try to test the Web Service from the WSNavigator, if I select the service from the SR I can successfully test it. But, when I try to search a web service from a Provider System and test it, the registered Web service is found but I cannot test it: I get the following error:

java.lang.NullPointerException: while trying to invoke the method java.util.List.iterator() of an object loaded from field com.sap.engine.services.webservices.espbase.query.WSInterfaceImpl.portTypeWsdls of an object loaded from local variable 'this'

Does anyone have an idea about where the problem may come from ?

Thanks in advance for your help,

Thibault
