Jaspersoft email are not working with TLS 1.2

Products

• Clarity PPM On Premise

Issue/Introduction

Following changes have been made in the Jaspersoft Server:

• In ../WEB-INF/applicationContext-report-scheduling.xml
  • <prop key="mail.smtp.starttls.enable">true</prop>
• In ../WEB-INF/js.quartz.properties
  •  report.scheduler.mail.sender.protocol=smtps
• It is however noticed that the following error is obtained, in the jasperserver.log. Emails are not sent out.
  • javax.net.ssl.SSLException: Unsupported or unrecognized SSL message

Environment

• Jaspersoft 9.0.0
• Clarity 16.3.2

Resolution

Note:

• This is one possible configuration. The other configuration is to use SMTPS from the beginning itself. That configuration is not dealt with here.

Change smtps to smtp, so that the initial handshake happens over the SMTP port. The connection is then upgraded to use SSL, by using the STARTTLS command.

Note: As a prerequisite the Start TLS will only work if the SMTP server has authentication set and that it shares the username and password. Without this setting, the remaining configuration as stated here shall not work, this has been confirmed by Tibco. 

Summary changes are as below:

• In ../WEB-INF/applicationContext-report-scheduling.xml
  • <prop key="mail.smtp.starttls.enable">true</prop>
• In ../WEB-INF/js.quartz.properties
  •  report.scheduler.mail.sender.protocol=smtp
