我已经尝试过重新部署、更新项目、清理并重新启动、重新安装glassfish工具、重新安装glassfish、重新安装eclipse

/PeeDeeWebFrontend
版本：

GlassFish服务器开源版本4.1.1（构建1）

Eclipse Jee Neon.1发行版（4.6.1）构建id:20160913-0900

JSF2.2.14版本15。2016年11月（原为2.1）

JAVA_VERSION=“1.8.0_102”OS_NAME=“Windows”OS_VERSION=“5.2” OS_ARCH=“amd64”

Maven 3（我想）

Java EE 7u2来自

我使用JavaEE7U2安装来配置我的项目
由于我对JSF、Glassfish、JSP和其他web开发工具完全不熟悉，所以我不知道为什么它不起作用，因为有几个示例建议它是这样的。有没有人能给我一个答案，或者告诉我为什么这不起作用

注意：我正在使用Glassfish工具在Eclipse中运行服务器
，因为我在自己身上找到了答案，下面的代码没有抛出运行时错误，只是一个编译器警告：

<input jsf:id="submit" name="submit" value="Register" type="submit"> <f:ajax render="@all" listener="#{registrationBean.register}" /> </input>

将其更改为：

<h:commandButton value="Submit" action="#{registrationBean.register()}" />

这解决了我的问题，找到并调用了EqualsValidator
在“流程验证”阶段，分别应用呈现和验证程序
有些渲染是隐式的：

javax.faces.Boolean

javax.faces.Byte

javax.faces.Character

javax.faces.Short

javax.faces.Integer

javax.faces.Long

javax.faces.Float

javax.faces.Double

javax.faces.BigDecimal

javax.faces.biginger

这意味着它们将自动应用于字段。因此，如果您有一个bean属性“int”和一个绑定该属性的值输入，并在其上加上一个字母，然后提交该值，则会自动应用隐式javax.faces.Integer并抛出一个异常。此时，如果您在该输入上有一个验证器，它将永远不会被调用
例：

什么不起作用？是否调用了
System.out.println
？您是否清理、构建和重新部署了所有内容？@ImproveAnything问题是什么？您粘贴了所有代码，但忽略了问题所在。
