unable to test restful web service

Question

I am creating a simple restful service and testing it using soapui. Everytime I am getting error : 500 : Internal server error. At server logs it shows class not found . Adding jars it starts conflicting. I think it is jar issue only but do not know exact jars.

web.xml :-

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>Service</display-name>
 <servlet>
        <servlet-name>Jersey REST Service</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>com.sun.jersey.config.property.packages</param-name>
            <param-value>com.service</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey REST Service</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>  
</web-app>

jars:-

com.springsource.org.objectweb.asm_2.2.3.jar
jersey-client.jar
jersey-core.jar
jersey-gf-server.jar

Java Code:-

package com.service;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

@Path("/cal/")
public class RestService {

    @GET
    @Path("/one/")
    @Produces("application/xml")
    public String sanction(){               
        return new Sanction().servesRequest();
    }
}

wadl path :- http://localhost:8090/Service/rest/application.wadl

I have tried changing jars, changing jersey servlet class name, eclipse, netbeans and many more but unable to get it on floor.

you may be having duplicate jars in class path http://stackoverflow.com/questions/8805249/exception-while-accessing-jersey-rest-webservice — kuhajeyan, Jul 14 '15 at 08:16
@kbird As I mentioned in my question this is jar issue but I am unable to know the required versions of which jars. — Harshit Bansal, Jul 14 '15 at 11:19

This was the jar issue. I was downloading jars from https://jersey.java.net/download.html which contains 3 folders namely api,ext,lib but I was not using all jars from these folders by mistake. I also had to change web.xml as these jars are for jersey2.19 so the new web.xml is like

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>Service</display-name>
 <servlet>
    <servlet-name>REST Web </servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.service</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>REST Web </servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>

</web-app>
