Why jboss service failed to start and why I have 404 error with my rest?

Question

I am new at restful web services. I wanted to write some code where I want when i write this url http://localhost:8080/EmployeeService-0.0.1-SNAPSHOT/rest/emp/get/101 to get my Employee that i inserted manually. This is my Employee class: k

@XmlAccessorType(XmlAccessType.NONE)
@XmlRootElement(name = "employee")
public class Employee {
    public String empID;
    public String name;
    public String email;
    @XmlElement(required = true)
    public String getEmpID() {
        return empID;
    }
    public void setEmpID(String empID) {
        this.empID = empID;
    }
    @XmlElement(required = true)
    public String gettname() {
        return name;
    }
    public void setname(String firstname) {
        this.name = firstname;
    }
    @XmlElement(required = true)
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public Employee(String empID, String firstname, String email) {
        super();
        this.empID = empID;
        this.name = firstname;
        this.email = email;
    }
 public Employee(){}
}

This is my rest service:

 @Path("/emp")
public class EmployeeService {

    @GET
    @Path("/get/{empID}")
    @Produces(MediaType.APPLICATION_XML)
    public Employee getEmployee(@PathParam("empID") String empID){
        Employee employee = new Employee();
        employee.setEmpID("101");
        employee.setname("Mirela");
        employee.setEmail("vujicic.mirela95@gmail.com");
        return employee;
    }

this is my web.xml:

This is my error in console:

EDIT: I have solved problem with jboss. Now my only problem is that I receive 404 when I write url that I wrote above. When I start my index.jsp it works but when i run my rest it giving me 404.

And when i write http://localhost:8080/EmployeeService-0.0.1-SNAPSHOT/rest/emp/get/101 i get 404-not found. Could someone plese help me with these mistakes?

Answer 1

Have you configure your rest endpoint? Or where does /rest/ comes from?

Example:

@ApplicationPath("/rest")
public class JaxRsActivator extends Application {
}
