作者简介：高科华，南京航空学院计算数学专业硕士，有十年以上的企业信息化工作经验。目前的研究兴趣,J2EE企业应用、ERP软件研发、数据仓库系统研发。
1. 按照“ 用JBuilder2005开发spring MVC应用”一文建立基本的spring应用
2. 增加JDOM、Dom4J类库
3. 源文件如下,详细解释请看spring参考文档

HttpServletRequest req,
HttpServletResponse resp) throws Exception {
/*

wordList.add("hello");
wordList.add("world");
map.put("wordList", wordList);
return new ModelAndView("home", map);
}
}

e.setText(nextWord);
root.addContent(e);
}
// convert JDOM doc to a W3C Node and return
return new DOMOutputter().output(doc);
}
