Struts2表单验证不起作用

我使用netbeans 8和struts 2 xml字段验证（tomcat7）来创建一个web应用程序。形成。当我点击提交按钮而没有填写表格时，成功页面显示为空白，没有任何错误。我是否错过了将LoginAction-validation.xml连接到表单的步骤？也许我需要更新的插件？我在表单验证我的库文件夹下面的：Struts2表单验证不起作用

你有代码中有很多拼写错误/错误。修复它们并查看它是否有效。 –

正如你可以在the Apache DTD directory中看到的那样，没有像xwork-validator-2.3dtd这样的东西（在扩展中也有一个错字）。最新XWork的验证器是1.0.3，它是一个你应该使用：

<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.3//EN" 
      "http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">

也提醒始终使用的库相同的版本，例如2.3.15.3（或更好2.3.16.1）到处
