我已经用它撞了我的头好几个小时了，我不知道为什么会发生这种事

最近，我们开始了从JBoss4.2.3到JBoss6 Final的过程。我们使用的是JSF1.2。我已经成功地将应用程序改编成新的JBoss（主要是通过从WEB-INF/lib中删除一些JAR并对WEB.xml进行一点修改），应用程序启动得很好

问题是一些EL表达式没有得到解决，而另一些表达式得到了解决。我在日志中也得到0个异常或警告

我有一个名为“mapContext”的bean，它是在一个JSFXML配置文件中定义的。它被创造得很好。在我的JSF页面上，我有：

<h:inputHidden id="mapContextId" value="#{mapContext.webContextId}" />
（日志中有很多）

但是关于selectionPointSymbol或selectionPointSymbol4（根本没有定义这样的bean！）没有单独的日志，它们只在标准标记中使用

服务器日志中仍然没有错误或警告：(

更多细节：简单测试

仍然不知道发生了什么，因为没有日志表明有任何问题。

JSF默默地返回空白字符串，如果在EL代码段中没有定义“代码> MaultValue。< /P>

您是否绝对确定mapContext已正确配置？在迁移过程中很容易丢失它。

请确保以下事项：

  • 在
    /WEB-INF/lib
    中没有特定于servletcontainer的库，如
    el-*.jar
  • web.xml
    声明符合Servlet3.0规范（JBoss6支持）
  • web.xml
    不包含指向不同（显然不存在）EL实现的
    com.sun.faces.expressionFactory
    上下文参数
在我的问题中添加了更多细节。您是如何告诉JSF bean应该以该名称公开的？所有@Named内容在JSF 2.0进入绝对基础之前都不可用。一个带有#{mapContext}的页面应该在beans toString中结束。在那里放一个断点以确定。Thorbjørn，我在我的帖子中添加了一些有趣的细节。请查看。哦，伙计，非常感谢！！web.xml附带了旧规范，仍然在使用2.4！
