我自己写了个ThemeServlet，用RequestDispatcher，将请求根据theme设置转发到相应skins目录
/pages/greeting.jsp => /skins/default/greeting.jsp
/pages/greeting.jsp?theme=blue => /skins/blue/greeting.jsp

其中/pages是ThemeServlet处理的目录：


    <servlet-mapping>
        <servlet-name>themeServlet</servlet-name>
        <url-pattern>/pages/*</url-pattern>
    </servlet-mapping>

如果是和struts action结合，这样映射
/greeting.do =(actionForward)=> /pages/greeting.jsp =(forwarded by themeServlet)=> /skins/default/greeting.jsp
也很正常

但是，如果用struts tiles，却不能显示内容？


home.jsp:
<tiles:insert definition="homeLayout">
 <tiles:put name="top" value="/skins/default/greeting.jsp" />
 <tiles:put name="bottom" value="/greeting.do" />
</tiles:insert>

*top部分，能正常插入greeting.jsp的内容，bottom部分不行

应该怎么修改ThemeServlet呢？


ThemeServlet.jsp

    private String trapFolder = "/pages";
    private String skinsFolder = "/skins";

    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        String uri = request.getRequestURI();
        String context = request.getContextPath();
        String path = uri.substring(context.length());
        if (path.startsWith(skinsFolder)) {
//            RequestDispatcher rd = request.getRequestDispatcher(path);
//            rd.include(request, response);
            return;
        }
        
        path = path.substring(trapFolder.length());
        
        String themeName = request.getParameter("theme");
        if (themeName == null || themeName.length() == 0)
            themeName = "default";
        
        
        String page = skinsFolder + "/" + themeName + path;
        
        RequestDispatcher rd = request.getRequestDispatcher(page);
        rd.include(request, response);
    }
