Jboss Javamail:javax.net.ssl.SSLHandshakeException:sun.security.validator.validator从VPS发送邮件时发生异常

jboss

Jboss Javamail:javax.net.ssl.SSLHandshakeException:sun.security.validator.validator从VPS发送邮件时发生异常,jboss,seam,jakarta-mail,vps,sslhandshakeexception,Jboss,Seam,Jakarta Mail,Vps,Sslhandshakeexception,我有以下问题。我有一个SeamWeb应用程序，它的特点是电子邮件合成和使用Javamail发送。该应用程序在我的本地JBoss应用程序服务器中发送邮件，但在我的myhosting.com VPS中安装的JBoss服务器上无法工作。我读到这个问题可能是因为我试图连接的web服务器或URL没有来自授权CA的有效证书，但我运行了一个实用程序（），它允许我验证证书，并且它们看起来很好（我正在连接到Gmail） 设置会话属性的相关代码如下所示： props.put("mail.smtp.auth", "t

我有以下问题。我有一个SeamWeb应用程序，它的特点是电子邮件合成和使用Javamail发送。该应用程序在我的本地JBoss应用程序服务器中发送邮件，但在我的myhosting.com VPS中安装的JBoss服务器上无法工作。我读到这个问题可能是因为我试图连接的web服务器或URL没有来自授权CA的有效证书，但我运行了一个实用程序（），它允许我验证证书，并且它们看起来很好（我正在连接到Gmail）

设置会话属性的相关代码如下所示：

props.put("mail.smtp.auth", "true");
props.setProperty("mail.smtp.starttls.enable", "true");
我了解到问题的另一个原因可能是使用mail.smtp.starttls.enable将其设置为true，但是如果我省略第二行或将属性设置为false，则代码（在我的本地服务器或VPS中）根本不起作用

我不知道问题是否与myhosting提供的mail2web邮件服务有关（请看下面我提供的两个日志中的第9行，这是事情开始不同的地方）。以下是本地Javamail日志和VPS的服务器日志（后者显示了我收到的错误）：

我应该怎么做才能消除这个错误？

问题解决了，它既不是网络问题，也不是代码问题。我们使用的是javamail-1.4，升级到1.4.4版后，问题就消失了。

您可以在（现在的版本是1.5.5）升级库javax.mail.jar并添加代码：

MailSSLSocketFactory sf = new MailSSLSocketFactory();
sf.setTrustAllHosts(true); 
props.put("mail.smtp.ssl.trust", "*");
props.put("mail.smtp.ssl.socketFactory", sf);
您是否从VPS本身运行上述实用程序？它的信任库似乎有问题。是的，更新库是解决方案。通过使用Apache Commons Email，我们将所有这些“在这里和那里放置属性，手工完成所有操作”抛在脑后。它比java mail好吗？它构建在JavaMail之上：“Commons Email旨在提供发送电子邮件的API。它构建在java mail API之上，旨在简化。”（）。它允许你用更少的LOC和更少的麻烦发送邮件。
