See examples of domain-specific tasks that a business user would find useful to have available in the process designer: Enhance customer data;Validate Personal ID against Official State Service;Check customer health plan;Calculate tax… Continue reading Delivering domain logic with Custom Tasks

As expected as default over any REST communication, when the integration via client and Kie Server is done via REST, there is no guarantee on the delivery or retry of this message. The initialization of Kie Services Client requires an instance of org.kie.server.client.KieServicesConfiguration. When using the REST approach, we should create the instance of KieServicesConfiguration… Continue reading Consuming business assets via REST

How to configure notification for Human Task in jBPM

Karina Varela

Great post from Sudhish Nair, an expert on process and rules automation.

TechBlogs

jBPM provides options to configure notification emails to be send to any user if the human task is not started or not completed.

We will start with configuring JavaMail sessions via JNDI so that infrastructure for mail is handled.

We would be using “jbpm-server-7.37.0.Final-dist” version for this example.

Configure Mail Session in wildfly

In the standalone configuration for jBPM we need add below configurations.

Configure Socket binding for smtp-port

        <outbound-socket-binding name="mail-notification-smtp">
            <remote-destination host="smtp.gmail.com" port="465"/>
        </outbound-socket-binding>

host -: host name of SMTP server

port -: port no of SMTP server.

Configure Mail-Session in Mail subsystem

            <mail-session name="notification" jndi-name="java:/notificationMailSession" from="youremailid@gmail.com">
                <smtp-server outbound-socket-binding-ref="mail-notification-smtp" ssl="true" username="youremailid@gmail.com" password="yourPassw0rd"/>
            </mail-session>

from -: From address for your emails (Valid email account on SMTP server).

username -: username for the email account

password -: password for the email account.

Add below system property to standalone.xml file.

    <system-properties>      
       <property name="org.kie.mail.session" value="java:/notificationMailSession"/>
    </system-properties>
