190-756 Using Web Services in IBM Lotus Domino 7 Applications Brain Dump

Demo Question 5.

Roberto is trying to create a Domino Web service to return an array of 3 String values containing Employee information. As a start, he is hard coding some values to test his code. But when he examines the generated WSDL, Roberto does not see an array being returned from this Web service. What is the problem? Class GetEmpData Function getData() As Variant Dim empData(0 To 2) As String empData(0) = "This is the Name" empData(1) = "Here is the ID" empData(2) = "This is the Phone" getData = empData End Function End Class

A. The GetEmpData class is declared without the word Public. so it is a private class. The code within the class will return an array if the class is declared using: Public Class GetEmpData
B. The empData array should be declared as a Variant, since the getData function is returning a Variant value. Mixing the data types as in the sample code yields unpredictable results when generating the WSDL.
C. The getData function should be declared to return a String, since the empData array is declared as a String. Mixing the data types as in the sample code yields unpredictable results when generating the WSDL.
D. The getData function is returning a Variant. This does not provide enough information for the generated WSDL to interpret the data type. If Roberto declares the empData array in a separate class, then the getData function can return this other class, which will map to a complexType WSDL element.
