将jsf项目转换为facelets 2.0的问题

时间:2011-10-20 15:00:19

标签: java jsf facelets

我遇到了将项目从我认为 jsf 1.1或1.2转换为使用facelets 的jsf 2.0的问题。

我已经阅读了很多关于如何做到这一点的问题,我仍然遇到问题。我遇到的问题是 jsf标签没有呈现为html标签

我是JSF的新手,仍然试图掌握它。

            A very common problem in configuring
            MyFaces-web-applications is that the Extensions-Filter is
            not configured at all or improperly configured. This
            parameter will check for a properly configured
            Extensions-Filter if it is needed by the web-app. In most
            cases this check will work just fine, there might be cases
            where an internal forward will bypass the Extensions-Filter
            and the check will not work. If this is the case, you can
            disable the check by setting this parameter to false.

答案 0 :(得分:2)

此链接可能能够解释您的配置问题。 http://facelets.java.net/nonav/docs/dev/docbook.html#gettingstarted-setup-web

另外,在使用更复杂的代码库之前,我建议从教程或示例项目开始。

答案 1 :(得分:2)

那么,你想在Facelets上使用JSF 2.0吗?我想你还希望能够使用旧的JSP文件吗?

通过混合使用JSF 1.x和JSF 2.x声明来解决问题中的web.xml怪物是很难的。关键点是删除javax.faces.DEFAULT_SUFFIX(您错误地设置为.jsp)并更改FacesServlet上的*.xhtml映射。

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

此外,您的ExtensionsFilter可以更好地映射到FacesServlet的单个servlet映射。

<filter-mapping>
    <filter-name>extensionsFilter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

这样Facelets文件必须正常工作。如果foo.xhtml不存在,但确实存在foo.jsp,那么它将在*.xhtml网址格式后面提供。
