那些遇到过的问题

获取 - jsf2的错误"...工厂javax.faces.context.FacesContextFactory的备份".在grails插件项目中

WIL*_*MAN 3 grails plugins jsf-2

在开发模式下运行grails 2.01和tomcat(正常的STS开发人员下载)

我试图运行jsf插件,但它不会在grails 2中工作

所以对于我来说,我试图构建我自己的本地插件,将其构建为本机v2插件,并在途中了解插件项目.已经解构(慢慢)grails jsf2插件并一点一点地重建它并随着我去学习

我的问题如下 - 我在本地构建了我的插件 - 称为'wwjsf'

我已经完成了doWithWebDescriptor闭包 - 但是当我运行插件时我得到一个错误 - 并且服务器不会呈现.xhtml文件 - 任何此类请求都会出现同样的错误.

我已将最新的mojarra jsf 2.1.7 api/impl文件包含到我的项目构建路径中 - 这是在grails 2.01中嵌入的默认tomcat的错误

我已经在闭包中完成了web.xml的转储,以便查看.我在谷歌上查找错误,它说你必须设置facesConfigureListener - 我有,我已经检查了xml中的faces服务器元素,我觉得它看起来不错.

另外我在WEB-INF下面放了一个空的faces-config.xml(我会担心如何在以后使用该插件的项目中创建它),并且正如一些谷歌警告说我必须拥有WEB-INF/lib目录中的jsf文件 - 我手动创建了/ lib并将我的jsf 2.1.7 api/impl jar复制到其中 - 带和括号

如何摆脱嵌入式tomcat服务器中的此错误？有点卡住了,直到我能通过这个问题

非常感谢dev论坛上的任何人的帮助(道歉第一部分不想格式化,即使我在每行之前放了四个空格......)最终web.xml配置看起来像:

当我遇到这个错误时(我使用maven和嵌入式jetty以及spring和jsf2),我在web.xml上添加了这个 

 <listener>
        <listener-class>com.sun.faces.config.ConfigureListener</listener-class> 
    </listener>

错误消失了.
