Getting Null Values while testing SOAP Web Service using SOAP UI

Question

I am trying to test SOAP Web Service using SOAP UI. but getting null values even passing those in soap ui while accessing parameters of request in our java method which has mapped endpoint to the operation.

Please find the code as below:

    @PayloadRoot(namespace = NAMESPACE_URI, localPart = "UserList")
        @ResponsePayload
        public JAXBElement<UserListResponse> UserListRequest(@RequestPayload JAXBElement<UserListRequest> request) throws Exception {

            System.out.println("Enters into UserList()");

            try {


                UserListRequest userListRequest = request.getValue();



   System.out.println("Number:"+userListRequest.getNumber());//Getting Number is null even passing passing in SOAP UI



      System.out.println("ID:"+userListRequest.getHeader().getCorrelationID()); //Here also getting java.lang.NullPointerException
//As i am not getting why soap Ui values are not binding and object reference is coming to userListRequest.
                if(userListRequest.getReference().equals("C")) {
                    userListRequest.setNumber(userListRequest.getNumber());
                }
            }
            catch(Exception e) {
                e.printStackTrace();
            }
            return null;
        }

Request XML:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:prim="http://COM.SERVICES.WebServices/UserServices">
   <soapenv:Header/>
   <soapenv:Body>
      <prim:UserList>
         <!--Optional:-->
         <prim:XMLRequest>
            <!--Optional:-->
            <prim:Header>
               <!--Optional:-->
               <prim:MessageID>2</prim:MessageID>
               <!--Optional:-->
               <prim:CorrelationID>2</prim:CorrelationID>
               <!--Optional:-->
               <prim:SystemID>2</prim:SystemID>
               <!--Optional:-->
               <prim:RequestorID>2</prim:RequestorID>
            </prim:Header>
            <prim:Reference>C</prim:Reference>
            <!--Optional:-->
            <prim:Number>1120521877477751</prim:Number>
            <!--Optional:-->
            <prim:Usercount>51</prim:Usercount>
         </prim:XMLRequest>
      </prim:UserList>
   </soapenv:Body>
</soapenv:Envelope>

I am unable to get why it is giving null . Can anyone please help me on this issue to resolve.

I would advise you to learn about debugging Java in general. When it comes to your mistake, I think it comes from there:

if(userListRequest.getReference().equals("C")) {
    userListRequest.setNumber(userListRequest.getNumber());
}

Your userListRequest's reference is likely null, thus you are trying to call:

if (null.equals("C"))    {
    // Your treatment

To tackle the problem, put the oracle (= static member) on the left of your comparison:

if ("C".equals(userListRequest.getReference()))    {
  userListRequest.setNumber(userListRequest.getNumber());
}

It won't make your reference not null, but it won't crash anymore.

EDIT

For your null issue while binding SoapUI to Java, check this answer which may help you find out what the problem is. It may come from your model itself. Now that you posted your request, we can see that the Reference object is there, in the XML Tree:

UserList
    XMLRequest
        Reference

From what I see there, it should look like this:

userList.getXMLRequest.getReference();

However, you try to retrieve:

userListRequest.getReference();

I don't know how you wrote your POJO model, but something is off there. Try to check if this architecture is correctly implemented, before anything else.
