调用RESTful Web服务时jQuery getjson不起作用

Question

I'm trying to call a restful webservice from my jsp page.

The restful web service is working fine and it is displaying the json data. The problem is with the client.
The client is not able to get the web service data.

I tried many ways but nothing worked.

This is the script:

function getEmployeeDetails() {
    alert("Hai");
    alert($("#empid").val());
    $empid = $("#empid");
    alert("eval-->" + $empid.val());
    $.getJSON("http://localhost:8080/RestfulWS/restful/employee/" + $empid.val(), displayResult);

}

function displayResult(data) {
    alert("data" + data);

    $("#fname").val(data.firstName);
    $("#lname").val(data.lastName);
}​

and the HTML

<form id="form1">
    <h2>Employee Details</h2>
    <table>
        <tr>
            <td>Employee ID : </td>
            <td><input type="text" id="empid" size="10"/> <input type="button"  value="Get Details" onclick="getEmployeeDetails()" /> </td>
        </tr>
        <tr>
            <td>FirstName : </td>
            <td><input type="text" id="fname" readonly size="30"/></td>
        </tr>
        <tr>
            <td>LastName :  </td>
            <td><input type="text" id="lname" readonly size="30"/></td>
        </tr>        
    </table>
</form>​

I am running the above code on tomcat with the port 19090.

Ok, Read HTTP access control , Cross-Origin Resource Sharing
