Hi Martin/All ... Got it going.Finally could send mails. Had to provide auth details(javamail session properties) in my jbpm.cfg.xml file. - for sending mails using smtp hosts(other than localhost) ... we need to provide the details like mail.smtp.host, mail.smtp.port, mail.smtp.auth, mail.smtp.user, password in a properties file or individually in jbpm.cfg.xml file. - Without providing these details,we can send mails only to the localhost.Can verify this by using the http://localhost:8080/jbpm-mail/inbox (to use this,first we need to deploy jbpm-mail war on tomcat) Martin,Thanks for your time and support.
