            model.addAttribute("details ", details );
            return "Status";
        }

    }

    <html>
    <body>
            <h2>Spring MVC and List Example</h2>

        <c:if test="${not empty details}">

                    </tr>

                        <td>${listValue.lastChecked}</td>
                    </tr>

So you need to make another GET request to the same URI. A clean way that doesn't depend on JavaScript is using a form:

<form>
    <button type="submit">Load</button>
</form>

If you dont't specify an action-attribute on the form element, the GET request is made to the same URI as the current page (in HTML5). In HTML4 the action attribute is required, so you can use the following:

<form action="<c:url value="/status" />">
    <button type="submit">Load</button>
</form>

If you need to display the same JSP page, then regardless actual URL, you can use something like:

<button onclick="window.location.href=window.location.href;">Load</button>

Also it can be slightly shorter, but please note, that it won't work for old IE versions.

<button onclick="window.location.reload();">Load</button>

<button onclick="window.location.href='/status'">Load</button>

if your jsp has form you can submit form to action='/status' url
