Jsf SimpleCRUD登录失败

我正在使用的平台：

• 软呢帽20
• mariadb-5.5.34-2.fc20.x86_64
• www.Eclipse.org上的Eclipse开普勒服务发布
• ApacheTomee plus 1.6.0

我正在实现一个示例

我正在尝试使用登录界面。我的问题是login.xhtml网页正确获取用户名和密码，但是

public void login(ActionEvent actionEvent) 

java对网页登录按钮的响应不正确。特别是，该网页没有说明用户名和密码的正确性。要查看应该发生什么，请参见上一链接中的交互式示例。 取而代之的是我电脑上发生的事情的简短视频

为了了解发生了什么，我将一些控制台输出放在JavaBean中，我发现getter/setter方法正在工作，唯一不工作的方法是

public void login(ActionEvent actionEvent) 

确实是印刷品

System.out.println("Entering in public void login(ActionEvent actionEvent)");

不会出现在控制台中

Login.xml

里面是什么（2）：

我上载了两个conf目录，以便您可以查阅它们

要将TomEE配置为使用JAAS操作，我要求： 所以我用这种方式在Eclipse中配置了TomEE

• 我在apache-tomee-plus-1.6.0-JAAS/conf/server.xml中添加了JAAS标记
• 在中添加了login.config和login.properties apache-tomee-plus-1.6.0-JAAS/conf/

视频控制台：

将commandButton标记的属性改为

actionListener

而不是

action

应该可以解决问题。

你能发布你的web.xml文件吗？你可以在帖子中找到Github链接：-）我在这里再次粘贴它尝试将commandButton标记的属性改为

actionListener

填写答案，而不是

操作

@Omar，这样我就可以给你打绿色分数了

<p:commandButton value="Submit" update="msgs" action="#{loginController.login}" icon="ui-icon-check" style="margin:0" />

<p:commandButton value="Submit" update="msgs" action="#{loginController.login}" icon="ui-icon-check" style="margin:0" />
