@PathParam getting null value

Thank you for your help even if you just read it.

Problem: return value is null why? Have checked many forums and everything seems to be fine, but isn't.

package pack.bb;

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

@Path("path")
public class test {
    @GET
    @Path("{sorted}")
    public String getsortedContactList(@PathParam("list") String list) //throws SQLException
    {
        System.out.println("GET list: " + list);
        return "get " + list;
    }
}

I am using this using localHost 8080 

"localHost:8080/testCap/api/path/aaaa"

This is web.xml file. I think it is correct because I was using it in other projects

        <param-name>com.sun.jersey.config.property.packages</param-name>
        <param-value>pack.bb</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
        <servlet-name>Jersey REST Service</servlet-name>
        <url-pattern>/api/*</url-pattern>
  </servlet-mapping>
</web-app>

After running I get this result in console:

GET list: null

It should be

@Path("/{list}")
public String getsortedContactList(@PathParam("list") String list)

Instead of {sorted}. The first @Path identifies the section in the url and @PathParam then tells which variable is used for it, so they have to match. The last one, variable name, can be anything.
