1. Re: Email Service Task - "Cannot find work item handler for Email"
josdel Mar 21, 2014 5:24 AM (in response to minamesephy)Hi Tali,
You should register the workitem Handler for Service Tasks. For email service task
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
ksession.getWorkItemManager().registerWorkItemHandler("Notification", new NotificationWorkItemHandler());

swiderski.maciej Apr 24, 2014 12:47 PM (in response to lakshjee)check section 5.4.4.2 of configuration in docs. There are few ways you can select to register handlers where the simplest one is to edit CustomWorkItemHandlers.conf finale that is inside kie-wb/WEB-INF/classes/META-INF

Thanks for your quick response. I have edited my CustomWorkItemHandlers.conf as follows. But still get the same error. Please assist me since i am a newbie.
[
"Log": new org.jbpm.process.instance.impl.demo.SystemOutWorkItemHandler(),
"WebService": new org.jbpm.process.workitem.webservice.WebServiceWorkItemHandler(ksession),
"Rest": new org.jbpm.process.workitem.rest.RESTWorkItemHandler()
;
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
ksession.getWorkItemManager().registerWorkItemHandler("Notification", new NotificationWorkItemHandler())

5. Re: Email Service Task - "Cannot find work item handler for Email"
swiderski.maciej Apr 25, 2014 1:37 AM (in response to lakshjee)you should define another mapping for handler and not put code into the conf file e.g.
"Email" : new org.jbpm.process.workitem.email.EmailWorkItemHandler("host", "port", "user", "password")

swiderski.maciej Apr 25, 2014 2:22 AM (in response to lakshjee)check your server log as there might be reason why it cannot send email. Please make sure that you specified correct settings for your mail server in the conf file - replacing host with actual host name or IP address of your mail server, and same for port, user and password.

swiderski.maciej Apr 28, 2014 1:30 AM (in response to lakshjee)that means you have not specified body of your email that should be set on the email task. Please populate all the fields for Email task and try again.

lakshjee Apr 28, 2014 2:15 AM (in response to swiderski.maciej)Thanks for your prompt response.
Now i get following message i think it os because of im working in a secured network environment.
- java.net.UnknownHostException: smtp.gmail.com
at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java
:178) [rt.jar:1.7.0_11]
at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:157) [rt.jar:1.
- 7.0_11]
Does this work if I change my network environment?
Thank you.

12. Re: Email Service Task - "Cannot find work item handler for Email"
swiderski.maciej Apr 28, 2014 3:43 AM (in response to lakshjee)yes, that is pure communication error caused by your network settings as the external server cannot be found, make sure you can access that server from the machine where jbpm is running and that should solve the issue.

14. Re: Email Service Task - "Cannot find work item handler for Email"
rafaelcba Jul 23, 2014 5:38 PM (in response to minamesephy)Hi swiderski.maciej!
Is possible to pass the Work Item Handler constructor's parameters through the Task DataInputs?
For example the Email Handler constructor receives: host, port, user and password parameters. But they are static in the CustomWorkItemHandlers.conf descriptor. Would be nice if the Handlers could be injected in runtime or be able to set the parameters througn Task DataInput values.
