Lotus Using Web Services in IBM Lotus Domino 8 Applications Sample Questions:

1. Sofie has created a LotusScript Domino Web service. She can compile successfully, and she can generate WSDL that appears to be correct. But the Web service is not returning the expected values. Sofie is considering adding messagebox statements within the Web service code in an attempt to help debug. Will messagebox statements return any output that she can examine?

A) No.Messagebox statements are front end calls. A messagebox statement in a back end routine will result in an abend.
B) No.Messagebox statements only display to UI. Since a Web service executes in the back end, the messagebox statements are ignored and produce no output.
C) Yes.Messagebox statements within a LotusScript Web service will write output to the server log. Sofie can browse the log to see these messages.
D) Yes.Messagebox statements within a LotusScript Web service are returned to the Web service consumer as WS_FAULT String values.

2. What statement needs to be added to the Options section of a LotusScript Web service in order to use special data types such as STRINGARRAY_HOLDER and XSD_DATETIME?

A) %INCLUDE "lsxsd.lss"
B) Nothing. These classes are available by default to aLotusScript Web service.
C) Use "wstypes"
D) %INCLUDE "wstypes.lss"

3. The WSDL files generated by Domino Web services typically contain the following namespace definition: xmlns:xsd="http://www.w3.org/2001/XMLSchema" What does this namespace relate to?

A) It defines common data types, such as string and integer.
B) It defines the elements in the basic WSDL structure, such asportType and binding
C) It does nothing. It is simply there for support of older Web services clients.
D) It defines the SOAP elements that are used in the request and response, such as header and body

4. Gill has written the following LotusScript Web service class: Class GetNum Private i As Integer Public Sub New(i As Integer) Me.i = i End Sub Public Function getInt() As Integer getInt = i End Function End Class He has set the PortType class properly, but he keeps getting an error when he tries to save the Web service. Why is he getting the error?

A) BecauseLotusScript Web services aren't allowed to have a "New" sub with parameters
B) Because the "Me" statement is not valid within Web service code
C) Because the Class was not defined to be "Public"
D) BecauseLotusScript Web services aren't allowed to have a "New" sub

5. Frances has a Web services client that generates the following SOAP message when calling a Domino Web service that has been written in LotusScript: <?xml version='1.0' encoding='UTF8'?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <SOAP-ENV:Body><ns1:GETPERSONINFO xmlns:ns1="urn:DefaultNamespace"SOAPENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> <PNAME xsi:type="ns1:PERSONNAME"><FIRSTNAME xsi:type="xsd:string">Billy Bob</FIRSTNAME> <LASTNAME xsi:type="xsd:string">Brubaker</LASTNAME> </PNAME> </ns1:GETPERSONINFO> </SOAP-ENV:Body> </SOAP-ENV:Envelope> Based on the structure of this message, which of the following represents the possible signature of the LotusScript function that implements the "GetPersonInfo" method?

A) Function GetPersonInfo (pname As PersonName, firstName As String, lastName As String) As PersonInfo
