OSB Conversion of Soap Service to JSON

Question

Hi All,
     I have a SOAP service that returns a list of employees which needs to be exposed in JSON format. I have nearly implemented this using XMLBeans by doing the following.
In the message flow of OSB, the JSON request is converted into XML and a Service Callout is made to the SOAP service which returns the Employees list in the response. The SOAP response is then assign to the variable 'responseXML' and then a Java callout is made to convert the 'responseXML' to JSON response. The Java callout method is as below. The XMLObject parameter passed from the OSB is a XMLfragment instead of the full XML document.
public static String employeeListResponseXmlToJson(XmlObject xml) {
        System.out.println("employeeListResponseXmlToJson() called with: " + xml.toString());
               ObjectWriter writer = EmployeeServiceMapperFactory
                .getEmployeeListWriter();
        EmployeeListResponse employeeListResponse =  new EmployeeListResponse();
        ArrayList <au.gov.vic.ambulance.pojo.Employee> employeeList = new ArrayList<au.gov.vic.ambulance.pojo.Employee>();
        String json = null;
        try {
            EmployeesDocument doc = EmployeesDocument.Factory.parse(xml.newXMLStreamReader());           
            if (doc instanceof EmployeesDocument) {
                EmployeesDocument employeesDoc = (EmployeesDocument) doc;
                Employees source = employeesDoc.getEmployees();               
                for (Employee emp: source.getEmployeeArray())
                    au.gov.vic.ambulance.pojo.Employee employee = new au.gov.vic.ambulance.pojo.Employee();
                    employee.setEmployeeNumber(emp.getEmployeeNumber());
                    employee.setFirstName(emp.getFirstName());
                    employee.setMiddleName(emp.getMiddleName());
                    employee.setLastName(emp.getLastName());
                    employee.setPreferredName(emp.getPreferredName());
                    employee.setPreviousLastName(emp.getPreviousLastName());
                    employee.setTitle(emp.getTitle());
                    employee.setHireDate(emp.getHireDate());                  
                    employeeList.add(employee);
                employeeListResponse.setEmployeeArr(employeeList);
                json = writer.writeValueAsString(employeeListResponse);
        } catch (XmlException e) {
            e.printStackTrace();
        } catch (JsonGenerationException e) {
            e.printStackTrace();
        } catch (JsonMappingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        return json;
The XML in the 'responseXML' variable is a as below
<Employees xmlns:es="http://abc.com/employee>
    <Employee>
    </Employee>
    <Employee>
    </Employee>
</Employees>
The XML after Java callout is made from OSB is a as below.
<xml-fragment>
    <Employee>
    </Employee>
    <Employee>
    </Employee>
</xml-fragment>
Why is OSB not passing the entire XMLDocument? Please suggest and help.
Thanks

Answer 1

Use the JSON libraries like jackson, Gson etc. to convert the from java collection to json that would be much easier. I recently done the same in my webservices.
