Hi All ... I am trying to send a mail from my work flow. I am using Eclipse plugin to build and deploy my workflow. processdefinition.xml file looks like this | <?xml version="1.0" encoding="UTF-8"?> | | <process-definition | xmlns="urn:jbpm.org:jpdl-3.2" name="mailing"> | | <swimlane name="SL_bert"> | <assignment actor-id="bert"></assignment> | </swimlane> | | | <start-state name="SN_Mailing"> | <transition name="N_MailAction_SendMail" to="N_MailAction_SendMail"></transition> | </start-state> | | <node name="N_MailAction_SendMail"> | <event type="node-enter"> | <mail name="M_MailAction" to=&quot;someid(a)gmail.com&quot; template="jbpm.mail.templates.xml"> | <subject>Subject: Mail action - mail</subject> | <text>Text: This mail is of type- mail actions</text> | </mail> | </event> | <transition name="EN_Mailing" to="EN_Mailing"></transition> | </node> | | <end-state name="EN_Mailing"></end-state> | | </process-definition> | I am using mail action inside the event to send a mail. When i try to deploy the process following Exception is thrown.
