Error while attempting to send mail

[sagyer]

Hello,

I am trying to send a mail from my jbpm workflow using the mail-node.

Here is my processdefinition.xml

<?xml version="1.0" encoding="UTF-8"?>
<process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="SendMail">

 <start-state name="start-state1">
 <transition to="mail-node1"></transition>
 </start-state>

 <mail-node name="mail-node1" to="[e-mail]">
 <subject>TestJBPM</subject>
 <text>Sent using a mail node.</text>
 <transition to="end-state1"></transition>
 </mail-node>

 <end-state name="end-state1"></end-state>

</process-definition>

I have added the element :

<string name="mail.smtp.host" value="172.25.8.13" />

to config/jbpm.cfg.xml

I get the error below :

I also tried changing src/jpdl/org/jbpm/default.jbpm.cfg.xml as well to modify the relevant element to

<string name="mail.smtp.host" value="172.25.8.13" />

I have tried sending a mail using java code using this smtp address. It works.

I am using jBPM version 3.2.2

Kindly help.

A little clarification :

I also tried changing src/jpdl/org/jbpm/default.jbpm.cfg.xml as well to modify the relevant element to

<string name="mail.smtp.host" value="172.25.8.13" />

The above change doesn't help; I get the same error as in the above post.

seems to have nothing to do with jBPM. Can you send email from java at all?

Yes, I can send mail from java from the same machine. Here is the code that sends the mail. I have tested this code and it works :

 public static void main(String[] args) throws AddressException,
 MessagingException {

 String smtpHost = "172.25.8.13";

 String from = "[e-mail]";
 String to = "[e-mail]";
 String cc = "[e-mail]";
 String bcc = "";
 String message = "Test Mail";
 String subject = "Test Subject";

 Properties props = new Properties();
 props.put("mail.smtp.host", smtpHost);
 Session session = Session.getInstance(props);

 // Instantiate a message
 Message msg = new MimeMessage(session);

 // Set message attributes
 msg.setFrom(new InternetAddress(from));
 InternetAddress[] address = { new InternetAddress(to) };

 msg.setRecipients(Message.RecipientType.TO, address);
 if (!("".equals(cc))) {
 InternetAddress[] addresscc = { new InternetAddress(cc) };
 msg.setRecipients(Message.RecipientType.CC, addresscc);
 }
 if (!("".equals(bcc))) {
 InternetAddress[] addressbcc = { new InternetAddress(bcc) };
 msg.setRecipients(Message.RecipientType.BCC, addressbcc);
 }
 msg.setSubject(subject);
 msg.setSentDate(new Date());

 // Set message content
 msg.setText(message);
 // ////////////////////////////////////////

 // Send the message
 Transport.send(msg);

 System.out.println("Sent mail successfully");

 }

afaik jBPM does the same, so no idea why there is a connection reset. Does your mailserver log anything?

[kukeltje]

oh and is the sending from java from the same machine as where jBPM runs on?

[sagyer]

Yes, the code is working from the same machine.
