I am new to WS I am trying to learn and create a RESTful WS in Eclipse IDE.I have followed couple of tutorials from Youtube. I am not able to find any around setting up your environment.On google I followed different posts and learnt about how to set up my env. However I am still failing to get the project deployed successfully.
Please excuse for the stupid question but I am not able to figure out how to resolved this.
I am using Jersey 1.17.1 library and Tomcat 7 server. My deployment is failing. Please help
Below are the artifacts of my project: My Class:
package com.service.user;
import javax.ws.rs.*
@Path("/user/service")
public class UserServices {
@PUT
@Path("/create")
public void creatUser()
{}
@GET
public void getUser()
{
System.out.print("Inside the getUser Method");
}
@POST
public void updateUser()
{
System.out.print("Inside the Update user Method");
}
@DELETE
public void deleteUser()
{}
}

In the process of trying to resolve the error I came across some posts which said that I need Maven. Have converted my project to Maven Project and below is my pom.xml
