    Error while attempting to send mail

    Sagar Yerunkar Newbie

      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="sagar.yerunkar@lntinfotech.com">
       <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.
