Question

我的项目使用JSF 2.1，RichFaces 4.1和GlassFish 3.1.2。我在web.xml中注册了一个过滤器。
问题：如何过滤自动包含在项目中的JSF和RichFaces（例如javax.faces.resource / richfaces-queue.js.xhtml）的资源？

的web.xml

JSFAuthenticationFilter

public class JSFAuthenticationFilter implements Filter {

    // ... variables

    @Override       //initialize
    public void init(FilterConfig filterConfig) throws ServletException {
        // ... do something
    }

    @Override      //filtering URI
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        HttpServletRequest httpRequest = (HttpServletRequest) request;
        HttpSession httpSession = httpRequest.getSession(true);
        HttpServletResponse httpResponse = (HttpServletResponse) response;
        String servletPath = httpRequest.getServletPath();

        //excluded data for the filtration (/javax.faces.resource/richfaces-queue.js.xhtml and other)
        if (isURLExcluded(servletPath)) {
            chain.doFilter(request, response);
            return;
        }

        //processed data to filter (/login.xhtml and /index.html)
        if (isURLIncluded(servletPath)) {
            // ... do something
        } else {    //for errors page
            httpResponse.sendError(HttpServletResponse.SC_NOT_FOUND, MessageFormat.format("Error message: page:{0} not found", servletPath));//404
            chain.doFilter(request, response);
            return;//redirect -> errorPage.xhtml
        }
    }

    @Override
    public void destroy() {
        // nothing to do here
    }
}

问题＃1：如果浏览器地址栏输入路径 HTTP：///myapp/javax.faces.resource/richfaces-queue.js.xhtml 窗口将打印包含资源的所有文本

问题＃2：要检查我使用regexp的Excluded资源。如果输入有效地址，例如 http：///myapp/javax.faces.resource/richfaces2-queue.js.xhtml 窗口将打印：

解析XML时出错：找不到元素地址： HTTP：///myapp/javax.faces.resource/richfaces2-queue.js.xhtml 第1行，第1个字符：

不会重定向到页面 ErrorPage.xhtml ，而且GlassFish日志中没有信息。请告诉我，让我过滤资源并切换到错误页面？
