freemarker 可以使用jsp标签，但只有你用了他的 freemarkerservlet，这个功能才能有效。如果你想生成静态文件那么这样就不行了
使用jsp标签的方法 使用心得
<#global hm=JspTaglibs["/WEB-INF/struts-html.tld"]>
<@hm.form action="logon.do" method="post">
<@include_page path= "/error.jsp"/>
可以这样来支持jsp标签
也可以支持jsp:include 这个标签
其本质是在model中添加了 对jsptaglibs和tabinclude 的标记
这是 freemarkerservlet 中 对templateModel的初始化 从以下红色代码可以看出，想要自己处理jsptaglibs 而不去调用它的servlet 只需要在自己的model中添加上这个值对就可以了，应用环境 servlet
需 要注意的一个问题 使用include这个标签是 由于传入的是request和response这两个参数，include来的内容会写入到response中，而不是自己指定的out中，所以这部分可 能需要进行一些修改，如果只是其用来做表示层 那么很容易（本来就是这么做的）
