Javamail发送带附件的邮件适用于Windows，但不适用于Linux

在Tomcat 6.0上使用Javamail发送带附件的电子邮件时遇到问题。Javamail发送带附件的邮件适用于Windows，但不适用于Linux

在我的机器上使用Tomcat服务器发送邮件时（Windows 7 64），它工作正常。我已经用本地smtp服务器和一个Gmail账户作为中继来测试它。但是，当我的远程Tomcat服务器（运行linux）发送邮件时，收到的邮件乱七八糟，没有主题，附件显示为文本（原始为pdf文件），并且一些邮件标头与邮件混合在一起。我尝试过使用在Windows上测试时使用的相同方法：尝试使用本地smtp服务器，然后使用gmail作为中继。它在两种情况下都不起作用。

我也尝试更改我的本地JavaMail库，并使用远程服务器上的相同内容（从服务器复制到我的机器），但运行本地的结果始终相同。电子邮件以预期的方式收到。

当我发送电子邮件时，它会发送另一份副本给我，所以我可以跟踪发生了什么。在日志下面展示了两种邮件（原件和复印件），运行使用嵌入在我的j2ee.jar JavaMail的本地测试时（请参见下面的其他细节）JAVAMAIL输出：

在我的远程服务器上，我们有上下文/ WEB-INF/lib中的JavaMail库。我们拥有一个mail.jar和一个包含JavaMail的j2ee.jar。另外，在tomcat文件夹中还有另一个mail.jar（可以在日志中看到）和另一个包含Javamail的j2ee.jar。

我试着用最近的一个替换服务器的/WEB-INF/lib/mail.jar，但日志甚至没有改变。在我的本地测试中使用来自服务器的.jars会产生正确的结果。

请注意，我的服务器不显示一些应该存在的调试行。

下面是用来发送电子邮件的代码：

Properties props = new Properties(); 
props.put("mail.smtp.debug", "true"); 
props.put("mail.smtp.auth", "true"); 
props.put("mail.mime.charset", "ISO-8859-1"); 
props.put("mail.smtp.starttls.enable", "true"); 
props.put("mail.smtp.starttls.required", "true"); 
props.put("mail.smtp.host", smtpHost); 
props.put("mail.smtp.port", Integer.toString(port)); 
this.session = Session.getInstance(props, 
    new javax.mail.Authenticator() { 
     protected PasswordAuthentication getPasswordAuthentication() { 
     return new PasswordAuthentication(usr, pass); 
     } 
}); 

MimeMultipart mp = new MimeMultipart("mixed"); 
MimeBodyPart txtPart = new MimeBodyPart(); 

if(this.message == null){ 
    if(this.session != null){ 
     this.message = new MimeMessage(this.session); 
    } else { 
     throw new Exception(""); 
    } 
} 

this.session.setDebug(true); 
this.message.setFrom(new InternetAddress(this.from)); 
this.message.setRecipient(Message.RecipientType.TO, new InternetAddress(this.to)); 
this.message.setSubject(this.subject); 

txtPart.setDisposition(Part.INLINE); 
txtPart.setText(text); 
mp.addBodyPart(txtPart); 

for (int i = 0; i < this.attach.size(); i++) { 
    MimeBodyPart filePart = new MimeBodyPart(); 
    File file = (File) this.attach.elementAt(i); 
    FileDataSource fds = new FileDataSource(file); 
    DataHandler dh = new DataHandler(fds); 
    filePart.setFileName(file.getName()); 
    filePart.setDisposition(Part.ATTACHMENT); 
    filePart.setDescription("Attached file: " + file.getName()); 
    filePart.setDataHandler(dh); 
    mp.addBodyPart(filePart); 
} 

this.message.setContent(mp); 

Transport.send(this.message);

任何进一步的细节需要，请询问。

感谢您的考虑！

尝试从应用程序中删除j2ee.jar;其中包含某些JavaMail类的旧版本，这可能与mail.jar中的较新版本冲突。

（j2ee.jar的仅作为一些在编译时使用;它不应该在运行时使用）

它并没有奏效。我将JavaMail 1.4.5复制到/ WEB-INF/lib /并删除了j2ee.jar。 JavaMail调试输出保持不变，就好像我没有删除j2ee.jar并将新的JavaMail复制到应用程序库。我误解了Tomcat安装中的j2ee.jar，但我可以确认那里有一个mail.jar，里面有JavaMail 1.3.1类。我需要确保删除该文件能够解决问题，因为我们公司在该服务器上有其他产品，并且我不知道是否删除该mail.jar（在tomcat安装内）会中断任何应用程序。谢谢！ – b020 2012-04-27 20:00:56

还有一个Tomcat选项可以让你的应用中的类优先于服务器中的类;这可能有助于这里。 – 2012-04-27 23:17:23

我找不到任何关于此的内容。也许我在搜索中使用了错误的关键字。你能指点一下如何改变这个选项的方向吗？ – b020 2012-04-30 18:03:38
