What might cause NoResultsException: Error calling Web Service 'EMRWebServiceConn': java.lang.NullPointerException

Question

I am trying to call a soap web service but I get the following error:

[line: 15] WrappedException: Wrapped com.qvera.qie.exception.NoResultsException: Error calling Web Service 'EMRWebServiceConn': java.lang.NullPointerException

Relevant code:

...

var value = qie.callSOAPWebService(

   "EMRWebServiceConn",

   "WebserviceSoapBinding",

   "GetMed",

   soapEnvelope,

   false,

   parameterMap,

   60000);

...

Relevant WSDL:

...

  <wsdl:binding name="WebserviceSoapBinding" type="tns:Webservice">

    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>

    <wsdl:operation name="GetMeds">

      ...

    </wsdl:operation>

    <wsdl:operation name="GetAllergies">

      ...

    </wsdl:operation>

    <wsdl:operation name="AddMed">

      ...

    </wsdl:operation>

...   

 

Answer 1

Check to make sure the binding and operation are supported.  Looking at the above example the operation should be "GetMeds" instead of "GetMed"
