处理HTTP状态500

Question

In my JSP page I use this script:

<script type="text/javascript">
$("#birthDate").datepicker({ dateFormat: 'dd/mm/yy' });
$("#update").click(function (e) {
    var res = true;
    var alertMsg = "";
    $(".required").each(function (index) {
        if (this.value == null || this.value.length == 0) {
            alertMsg += this.name + " can't be empty! 
";
            res = false;
        }
    });

    if (res) {
        var response = $("#updateForm").submit();
        Window.location.reload();
    } else {
        alert(alertMsg);
    }
})

But, requested resource is not available, and I get this exception:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

How can handle this exception, so that on my page displays the error message?

Answer 1

You should see the actual response from your remote side. Most probably you'll see some boilerplate HTML saying your resource wasn't found, you are not authorized, or something similar instead of the actual WS response. This can happen when the WS server is hidden behind an Apache front end, which is misconfigured to assume you are a browser.
