Question

I am new to web service and I am exploring one particular idea regarding this topic.

Supposed I have a java class like below

public class Department{
    private int id;
    private String name
    private List<Employee> employees;
    //getters and setters
}

I want to create a Web Service method and I wanted it to expose the data
to follow a certain schema when I call this web service. This will basically
be the SOAP response schema.

<department>
    <id />
    <name />
    <employees type="list">
        <employee>
            <emp_id />
            <name />
        </employee>
        .
        .
    </employees>
</department>

The web service method will just find a department given a department id input parameter.
The output should follow the schema above

@WebService
public class Service{
    @WebMethod
    public Department getDepartment(int id){
      //code
    }
}

Is this possible?

Answer 1

You need to annotate your POJO class with proper JAXB annotations.

Here is an example :

@XmlAccessorType(value = XmlAccessType.NONE)
public class Department {


    @XmlElement
    private Long id
    @XmlElement
    private String name 
    @XmlElement
    private List<Employee> employees;

    // +accessor methods

} 

Also annotate your Employee class in the same manner.

And use

@WebService(name = "departmentServiceSOAP", targetNamespace = "/namespace")
@javax.jws.soap.SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
public interface DepartmentService {
    @WebMethod
    public Department getDepartment(Long id);
}
