在调试JSP时，我在哪里可以找到变量值？

Question

调试类似以下的JSP时，在IntelliJ中：

<c:when test="${not useBuiltScripts}">
    <script src="/static/js/jquery/dist/jquery.min.js" type="text/javascript" charset="utf-8"></script>
    <script src="/static/js/modernizr/modernizr.js?v=1.7" type="text/javascript" charset="utf-8"></script>
    <script src="/static/js/simpleFade.js" type="text/javascript" charset="utf-8"></script>
    <script src="/static/js/jcarousel/dist/jquery.jcarousel.js" type="text/javascript" charset="utf-8"></script>
    <script src="/static/js/prettyCheckboxes.js" type="text/javascript" charset="utf-8"></script>
    <script src="/static/js/sr-beauty-tips/jquery.bt.min.js" type="text/javascript" charset="utf-8"></script>
    <script src="/static/js/colorbox/jquery.colorbox.js" type="text/javascript" charset="utf-8"></script>
    <script src="/static/js/functions.js" type="text/javascript" charset="utf-8"></script>
</c:when>

当我在该行上有断点时，我应该在哪里查找useBuiltScripts的当前值？

我试过捣乱，但无济于事。
