<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

request.setAttribute("contextPath", path);

request.setAttribute("basePath", basePath);

%>

2    <script type="text/javascript" src="${contextPath}/platform/common/tree/dtree.js"></script>

 <script type="text/javascript">

  var basePath = "${basePath}";
