在用Jbpm3.2发送邮件时候，需要修改Mail中的send 方法，用到过的可能都发送过
public static void send(Properties mailServerProperties, String fromAddress, List recipients, List bccRecipients, String subject, String text) { // if ( (recipients==null) || (recipients.isEmpty())) { // log.debug("skipping mail because there are no recipients"); // return; // } // log.debug("sending email to '"+recipients+"' about '"+subject+"'"); // Session session = Session.getDefaultInstance(mailServerProperties, // null); // MimeMessage message = new MimeMessage(session); // mailServerProperties.put("mail.transport.protocol","smtp"); // mailServerProperties.put("mail.smtp.port","25"); // mailServerProperties.put("mail.smtp.host", "127.0.0.1"); if ((recipients == null) || (recipients.isEmpty())) { log.debug("skipping mail because there are no recipients"); return; } log.debug("sending email to '" + recipients + "' about '" + subject + "'"); // Session session = Session.getDefaultInstance(mailServerProperties, // null); Session session = null; String auth = JbpmConfiguration.Configs.getString("jbpm.mail.smtp.auth");// 这一行作者贴出的有笔误吧？我改成了"jbpm.mail.smtp.auth" if (auth != null && auth.equals("true")) { mailServerProperties.put("mail.smtp.auth", auth); String user = JbpmConfiguration.Configs.getString("jbpm.mail.smtp.user"); String password = JbpmConfiguration.Configs.getString("jbpm.mail.smtp.password"); JbpmAuthenticator jbpmAuthenticator = new JbpmAuthenticator(); jbpmAuthenticator.init(user, password); // session = // Session.getInstance(mailServerProperties,jbpmAuthenticator); session = Session.getDefaultInstance(mailServerProperties, jbpmAuthenticator); } else { session = Session.getDefaultInstance(mailServerProperties, null); } MimeMessage message = new MimeMessage(session); try { if (fromAddress != null) { message.setFrom(new InternetAddress(fromAddress)); } Iterator iter = recipients.iterator(); while (iter.hasNext()) { InternetAddress recipient = new InternetAddress((String) iter .next()); message.addRecipient(Message.RecipientType.TO, recipient); } if (bccRecipients != null) { iter = bccRecipients.iterator(); while (iter.hasNext()) { InternetAddress recipient = new InternetAddress( (String) iter.next()); message.addRecipient(Message.RecipientType.BCC, recipient); } } if (subject != null) { message.setSubject(subject); } if (text != null) { message.setText(text); } message.setSentDate(new Date()); Transport.send(message); } catch (Exception e) { throw new JbpmException("couldn't send email", e); } }

修改后，重新编译，打包。这里我是把源码源码修改后编译Mail.class放到对应的jar文件覆盖以前的Mail.class文件
粗略的记录了下，相信碰到类似的问题的朋友，希望对你们有用。
