[resolved] MessagingException caused by SSLException in tSendMail

[bluishjoe]

Hello, I'm facing following weird error.
Platform: Talend Open Studio 4.2.3
I create a simple job with a tSendMail component with minimal settings, no SSL, no STARTTLS.
I export it as an autonomous job and run it on Ubuntu server. It works.
Then I export it as a web service (WAR) and deploy it on the same Ubuntu server on Tomcat 6. In this case I get:

Exception in component tSendMail_1
javax.mail.MessagingException: Could not connect to SMTP host: xxx.xxx.xxx.xxx, port: 25;
  nested exception is:

Maybe is something connected with Tomcat or with the web services? Note that if I run the same job on Tomcat on another machine (but also with a different SMTP host) it works...
I'm going mad. Any help will be greatly appreciated!

Hi
Try to check the option STARTTLS and test again.
Best regards

Thanks for the reply.
I checked and unchecked the option STARTTLS, but no difference in the result.
Finally I solved the problem with a tJava, which sends the email.
Its imports (needs 2 tLibraryLoad for mail.jar and activation.jar):

import java.io.*;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

Its code:

//build and send the email
Properties props = new Properties();
props.put("mail.smtp.host", context.SMTP_HOST);
Session mail_session = Session.getDefaultInstance(props, null);
Message msg = new MimeMessage(mail_session);
msg.setFrom(new InternetAddress(context.MAIL_FROM));
Vector<String> recipients = new Vector<String>();
recipients.addElement((String)globalMap.get("mailcom"));
recipients.addElement((String)globalMap.get("mailcli"));
InternetAddress[] addressTo = new InternetAddress;
for (int i = 0; i < recipients.size(); i++)
	addressTo = new InternetAddress((String)recipients.elementAt(i));
msg.setRecipients(Message.RecipientType.TO, addressTo);
msg.setSubject(context.MAIL_SUBJECT);
msg.setSentDate(new Date());
Multipart mp = new MimeMultipart();
MimeBodyPart mbp = new MimeBodyPart();
mbp.setContent(context.MAIL_TEXT, "text/html");	    
mp.addBodyPart(mbp);
//add attachments
File attachments_folder = new File(context.ATTACHMENTS_SOURCE_FOLDER);
if (attachments_folder!=null){	//attachments folder exist
	File[] files = attachments_folder.listFiles();
	if (files!=null){
		for(File file : files){
			if (file.isFile()){
				mbp = new MimeBodyPart();
				DataSource source = new FileDataSource(file);
				mbp.setDataHandler(new DataHandler(source));
				mbp.setFileName(file.getName());
				mp.addBodyPart(mbp);   //add bodypart to the multipart
			}
		}
	}
}
msg.setContent(mp);
Transport.send(msg);
