问题描述

我需要抛出404并将访问者带到特定页面.我正在尝试以下代码:

I need to throw 404 and take visitor to a specific page. I am trying with following code:

            FacesContext facesContext = FacesContext.getCurrentInstance();
            ExternalContext externalContext = facesContext.getExternalContext();                
            externalContext.setResponseStatus(HttpServletResponse.SC_NOT_FOUND);
            externalContext.setResponseHeader(Common.LOCATION, "browse_by_category.xhtml?category=CATEGORY_ALL");
            facesContext.responseComplete();

404发生，但是没有重定向到Browse_by_category.xhtml页面. 任何帮助将不胜感激.
