How can I access a JAX-RS resource? - jax-rs

Question

I've created a simple JAX-RS resource class for my Java EE based project. I am trying to get a response back from the server but when I access my url I get an error back. This is the class that I wrote:
#Path("/rest")
public class RestResource {
#GET
#Produces(MediaType.APPLICATION_JSON)
public String create(String name)
{
return "print my string";
}
}
I cannot figure out what I'm doing wrong.
Do I have to define a new servlet in my web.xml? Is there something wrong with my current one?
<?xml version="1.0" encoding="UTF-8"?>

I managed to fix my problem by using RESTEasy. Here is my updated web.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
metadata-complete="false">
<session-config>
<session-timeout>30</session-timeout>
</session-config>
<display-name>crud-app</display-name>
<!-- Activate the JSF 2.0 servlet -->
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Tell the context which URLs to send through JSF -->
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<!-- Auto scan REST service -->
<context-param>
<param-name>resteasy.scan</param-name>
<param-value>true</param-value>
</context-param>
<!-- this need same with resteasy servlet url-pattern -->
<context-param>
<param-name>resteasy.servlet.mapping.prefix</param-name>
<param-value>/rest</param-value>
</context-param>
<listener>
