HTML中嵌入的Java小程序在发送电子邮件时挂起浏览器

java javascript

HTML中嵌入的Java小程序在发送电子邮件时挂起浏览器,java,javascript,applet,jakarta-mail,Java,Javascript,Applet,Jakarta Mail,我正在尝试创建一个网站，当有人打开它时，它会给我发送电子邮件。它存储在本地，所以我不能使用php。我决定使用Javaapplet，在做了很多工作之后，Firefox的applet出现了一些严重的问题，它几乎可以正常工作。小程序已完全加载、初始化、启动并对html按钮作出反应 我使用的是Javamail 1.4.4，Firefox和Opera两种浏览器的反应都是一样的，大约20秒后，它们再次正常工作，但邮件没有发送。这是堆栈跟踪： DEBUG: setDebug: JavaMail version

我正在尝试创建一个网站，当有人打开它时，它会给我发送电子邮件。它存储在本地，所以我不能使用php。我决定使用Javaapplet，在做了很多工作之后，Firefox的applet出现了一些严重的问题，它几乎可以正常工作。小程序已完全加载、初始化、启动并对html按钮作出反应

我使用的是Javamail 1.4.4，Firefox和Opera两种浏览器的反应都是一样的，大约20秒后，它们再次正常工作，但邮件没有发送。这是堆栈跟踪：

我还读到，我可以签署我的小程序，但它会调用一个弹出窗口，每次我的小程序加载，这不是一个选项，因为它必须有点隐藏

知道我做错了什么吗

如果您认为在这里使用小程序太复杂，请告诉我更好的方法。据我所知，JavaScript不能发送电子邮件，我没有服务器，所以我不能使用php或类似node.js的东西，所有其他发送信息的库都需要用户登录

欢迎加入恶意代码编写者俱乐部，其中恶意代码包括跟踪。您与浏览器w.r.t.新网络连接的同源策略相冲突，这意味着您可以连接到的唯一不需要签名的地方是为原始页面提供服务的主机。

一个发送电子邮件但必须隐藏一点的小程序？听起来很邪恶。如果您实现了这一点，请告诉我们如何实现，这样我们就可以在Oracle中发现一个安全漏洞并加以修复。这个网站是一个礼物。它将有一个视频，这是应该带回记忆。最后，我会请这个人为我开门。但是为了让我知道什么时候来，什么时候这个人真的在看，我需要电子邮件。如果这是邪恶的，那么我很抱歉。
