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="someid(a)gmail.com"
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.

Please let me know if I have done anything wrong?
What all configurations are involved in successfully executing a mailing workflow
process?
Kindly help.
Thanks in advance.
