我在 Netbeans 7.1.2 中创建了一个 Java Web 服务，并设法通过 netbeans 创建了一个 Java 客户端来测试它，并且它工作正常。然后我尝试创建一个 jQuery 客户端但失败了。
jQuery客户端代码是：
$.ajax({
type: "POST",
url: "http://luke-test.j.layershift.co.uk/ClubInService/getHello",
data: "{val:luke}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccessCall,
error: OnErrorCall
});
function OnSuccessCall(response) {
$tmp = "";
$.each(response, function(index, element) {
$tmp += element + ";";
});
alert($tmp);
}
function OnErrorCall(response) {
$tmp = "";
$.each(response, function(index, element) {
$tmp += element + ";";
});
alert($tmp);
}
我试图调用的函数是：
@WebMethod(operationName = "getHello")
public String getHello(@WebParam(name = "val", targetNamespace =
"http://clubinservice/") String val) {
return "Hello " + val + "!";
}
使用 jQuery 使用 Java Web 服务时，我收到此错误并且不知道这意味着什么：

如果有帮助，请随意尝试并使用 Web 服务上的功能。任何帮助都会很棒！

在意识到我应该使用 JSON.stringify 之后：
function OnSuccessCall(response) {
alert(JSON.stringify(response));
}
function OnErrorCall(response) {
alert(JSON.stringify(response));
}
我收到了不同的错误消息：
{"readyState":0,"responseText":"","status":0,"statusText":"error"}
$.post("http://luke-test.j.layershift.co.uk/ClubInService/getHello",
{val: "John"},
function(data){
alert(JSON.stringify(data));
}, "json")
.error(function(data){alert(JSON.stringify(data));});
它还返回了错误消息：
{"readyState":0,"responseText":"","status":0,"statusText":"error"}
