java - j2ee tomcat 中启动 java.util.concurrent.ExecutionException 时子容器失败

Question

我的 J2EE 简单项目有问题。在此应用程序中，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)，但我总是收到此错误。这是我的堆栈跟踪:

也许有人可以帮我解决这个问题吗？

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 映射不允许在映射定义中出现多个点，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);

}
