Error in context path

I Tried a Struts2 Login application having following class as Action class..

    package com.actions;

    import com.dao.EmpDao;
    import com.hibernate.employees;
    import com.opensymphony.xwork2.ActionSupport;
    import javax.servlet.http.HttpServletRequest;
    import org.apache.struts2.interceptor.ServletRequestAware;

    public class EmployeesAction extends ActionSupport implements ServletRequestAware {

    public HttpServletRequest request;
    private int employeeNumber;
    private String firstName=null;
    employees e=new employees();
    @Override 
    public String execute() throws Exception{

        String contextPath = request.getContextPath();
        System.out.println("Context Path " + contextPath);
        EmpDao empDao=new EmpDao();
        if(empDao.validate(getEmployeeNumber(), getFirstName()))
            {
             return SUCCESS;
            }
        else{
         this.addActionError("Invalid Credentails");
        }
         return ERROR;
    }

    public int getEmployeeNumber() {
        return employeeNumber;
    }

    public void setEmployeeNumber(int employeeNumber) {
        this.employeeNumber = employeeNumber;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    @Override
    public void setServletRequest(HttpServletRequest hsr) {
        throw new UnsupportedOperationException("Not supported yet.");
    }
