以下的代码片段演示了一个servlet，它例示(instantiates)一个bean并且用由浏览器发送的Form数据将它初始化。此后bean被加入request,而这一要求被送到JSP页面（Bean1.jsp）,JSP通过request取得并做进一步处理。 public void doPost (HttpServletRequest request, HttpServletResponse response) { try { govi.FormBean f = new govi.FormBean(); String id = request.getParameter("id"); f.setName(request.getParameter("name")); f.setAddr(request.getParameter("addr")); f.setAge(request.getParameter("age")); //use the id to compute //additional bean properties like info //maybe perform a db query, etc. // . . . f.setPersonalizationInfo(info); request.setAttribute("fBean",f); getServletConfig().getServletContext().getRequestDispatcher ("/jsp/Bean1.jsp").forward(request, response); } catch (Exception ex) { . . . } } 在将它从通过useBean操作中的缺省的请求范围，即scope首次执行后，即可在JSP文件的Bean1.jsp处理fBean。
