Create POJO based JAX-WS WebService easily with Jdeveloper 12.1.3

Hello All

In this post, I am talking about creating a simple JAX-WS web service using Jdeveloper 12.1.3 .
JAX-WS is a Java API for XML Web Services and we can create a JAX-WS easily with Jdeveloper IDE
Idea is to create a web service that shows Employees list with their name, designation, salary and department name so for this, I am going to use POJO Java Class

Let's implement it

Creating JAX-WS WebService

• Create a Java Desktop Application





• Give a name to application
  
  
  
• Create a Java Class in project 






• Here I am creating a Java Bean class to hold Employee Details variables




Java Code of EmpBean Class



public class EmpBean {
    public EmpBean() {
        super();
    }

    /**Constructior to add new Employee detail
     * @param name
     * @param desig
     * @param salary
     * @param dept
     */
    public EmpBean(String name, String desig, Integer salary, String dept) {
        super();
        this.name = name;
        this.designation = desig;
        this.salary = salary;
        this.departments = dept;
    }

    //Employees Details Variables
    private String name;
    private String designation;
    private Integer salary;
    private String departments;

    //Accessors
    public void setName(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void setDesignation(String designation) {
        this.designation = designation;
    }

    public String getDesignation() {
        return designation;
    }

    public void setSalary(Integer salary) {
        this.salary = salary;
    }

    public Integer getSalary() {
        return salary;
    }

    public void setDepartments(String departments) {
        this.departments = departments;
    }

    public String getDepartments() {
        return departments;
    }
}



• Create another class to hold Employees data and make use of bean class to add all information




Java Code of Employees Class



import java.util.ArrayList;
import java.util.List;

public class Employees {
    public Employees() {
        super();
    }
    //List to store Employees
    private List<EmpBean> empList = new ArrayList<EmpBean>();

    public void setEmpList(List<EmpBean> empList) {
        this.empList = empList;
    }

    public List<EmpBean> getEmpList() {
        //Add items in list onlt if it is empty
        if (empList.size() == 0) {
            empList.add(new EmpBean("Ashish Awasthi", "Software Engineer", 10000, "Project"));
            empList.add(new EmpBean("Shanto Mathew", "Software Engineer", 10000, "Product"));
            empList.add(new EmpBean("Gourav Raj", "Project Manager", 30000, "Project"));
            empList.add(new EmpBean("Bharat Lal", "Team Lead", 20000, "Product"));
        }
        return empList;
    }
}



• Now to create WebService add @WebService annotation just before class name and import javax.jws.WebService package





• Click on yellow bulb icon and select Configure project for web services and in dialog select with support for JAX-WS Annotations 







Click on Ok and your project is configured for WebServices and a Web.xml file is created

Testing WebService

• Right click on WebService class and select Test WebService





• This option starts integrated WebLogic server and initiates HTTP Analyzer after deploying WebService. Here you can see I have selected getEmpList method and click on Send Request button and it shows result in right window
