在j2ee tomcat中启动java.util.concurrent.ExecutionException期间子容器失败

我在J2EE中的简单项目有问题。在这个应用程序中，我添加了简单的登录表单（连接到数据库并检查登录名和密码），但我总是得到这个错误。这是我的Stack Trace：

也许有人可以帮我解决这个问题？

答案 0 :(得分：1)

您在日志中有明确的定义：

Caused by: java.lang.IllegalArgumentException: Invalid <url-pattern> facebookConnect.servlets.Login in servlet mapping

Url映射在映射定义中不允许多个点，请检查tomcat使用的代码来验证映射：

private boolean validateURLPattern(String urlPattern) {

    if (urlPattern == null)
        return (false);
    if (urlPattern.indexOf('\n') >= 0 || urlPattern.indexOf('\r') >= 0) {
        return (false);
    }
    if (urlPattern.startsWith("*.")) {
        if (urlPattern.indexOf('/') < 0) {
            checkUnusualURLPattern(urlPattern);
            return (true);
        } else
            return (false);
    }
    if ( (urlPattern.startsWith("/")) &&
            (urlPattern.indexOf("*.") < 0)) {
        checkUnusualURLPattern(urlPattern);
        return (true);
    } else
        return (false);

}

答案 1 :(得分：0)

错误很明显：

  

java.lang.IllegalArgumentException: Invalid <url-pattern> facebookConnect.servlets.Login in servlet mapping

检查servlet映射（web.xml文件）。 url-pattern元素需要URI模式，顾名思义，而不是Java类。

示例：

<servlet>
    <servlet-name>Servlet</servlet-name>
    <servlet-path>package.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet</servlet-name>
    <url-pattern>/hello</url-pattern>
</servlet-mapping>
