这是我的代码,点击本网站上的简单登录按钮

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;    
import org.openqa.selenium.WebDriver;    
import org.openqa.selenium.firefox.FirefoxDriver;    

public class Reports {

    public static void main(String[] args) {

        WebDriver driver = new FirefoxDriver();
        driver.get("https://platform.drawbrid.ge");
        driver.manage().timeouts().implicitlyWait(2, TimeUnit.SECONDS);
        driver.findElement(By.xpath(".//*[@id='_loginButton']")).click();

    }
}

我收到以下错误:

线程"main"中的异常org.openqa.selenium.ElementNotVisibleException:元素当前不可见,因此可能无法与命令持续时间或超时交互:2.05秒

我正在尝试安装node-java允许 Node.js 连接到现有JavaAPI 的模块。这是我用来安装此模块的命令：

须藤 npm 安装 java -g

这是我收到的错误的堆栈跟踪：

我是学习 Java Servlet 的新手。我正在尝试使用生成两个输入字段“用户名”和“全名”的简单 html 表单通过 POST 查询（Apache Tomcat v8.0）传递参数。然而，代码运行良好；我希望 'UserName' 和 'FullName' 显示在单独的新行上，我不能通过在 println() 函数中使用“/n”来实现。这是我的 POST 查询代码。

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    response.setContentType("text/html");
    PrintWriter out= response.getWriter();
    String User_name = request.getParameter("UserName");
    String Full_name = request.getParameter("FullName");
    out.println("\nHello from POST method!");
    out.println("\nYour UserName is: " +User_name);
    out.println("\nYour FullName is: " +Full_name);
}
