Problem at json from web url

i using the json jquery in the WebApplication Java with this method and working:

  1.   jQuery.ajax({
         type: "GET",
         url: "webresources/generic",
         dataType: "json",
       success: function(e){
         alert("yes");
      },
      error: function(e){
          alert("no");
      }
    });

  1.       jQuery.ajax({
      type: "GET",
      url: "http://localhost:8080/WebApplication21/webresources/generic",
      dataType: "jsonp",
      success: function(e){
          alert("yes");
      },
      error: function(e){
