Hi,
Who knows how to enable/establish email notifications in Flowable.
It will be great if as soon as a task is assigned to someone Flowable will be send a email notification to a user.
Best regards,
Zholaman
Hi,
this can be done by implementing a TaskListener.
Take a look in the docs here; TaskListeners

Yvo
Hi yvo,
I am sorry, maybe I didnāt expresse myself correctly.
I mean how Flowable can send email, how it can know what mail server/port to use and where I can point these settings.
Thank you in advance for your help!
Best regards,
Zholaman
Hi.
Do you mean how to configure the mail server settings on the engine?
If you provide the engine configuration yourself then something like this;
<!-- mail server configurations --> <property name="mailServerPort" value="5025" /> <property name="mailServers"> <map> <entry key="myEmailTenant"> <bean class="org.flowable.engine.cfg.MailServerInfo"> <property name="mailServerHost" value="localhost" /> <property name="mailServerPort" value="5025" /> <property name="mailServerUseSSL" value="false" /> <property name="mailServerUseTLS" value="false" /> <property name="mailServerDefaultFrom" value="flowable@myTenant.com" /> <property name="mailServerUsername" value="flowable@myTenant.com" /> <property name="mailServerPassword" value="password" /> </bean> </entry> </map> </property>
If youāre using the Flowable UI apps then you can configure it as described here UI apps docs
F.e. in the flowable-ui-apps.properties;
email.host=
email.port=
email.useCredentials=
email.username=
email.password=
Is this what you are looking for?
Regards,
Yvo
Dear yvo,
yes, it is what I am looking for!
Thank you a lot!
Best regards,
Zholaman
Dear yvo,
I have set the below options (in flowable-task->flowable-ui-app.properties) but it seems not working. Before to write the post I have checked an access to the mail server by telnet:
email.host=192.168.0.1
email.port=25
email.useCredentials=false
email.username=johnny.depp (also tried: johnny.depp@company.com)
email.password=pass
Also how I can explicitly to point mail protocol f.e. SMTP, IMAP etc
Thanks!
Best regards,
Zholaman
Hi
Based on the information provided I cannot tell what the reason is that it isnāt working.
Perhaps your mail server needs SSL / TLS ā¦
Youāre using the properties for the Task UI app. These are there for convenience. If you want more control on configuring the email server settings use a custom engine config.
Weāre using Apache Commons Email for sending emails.
Also; the build in support is for SMTP not IMAP. (IMAP is not for sending but for receiving)
Hope this help.
Yvo
Dear yvo,
our mail server use SMTP without SSL/TLS.
I tried to find any information about email sendings in Tomcat logs but no success, so if you have a time I will be appreciate to get any help/advice relating to this challenge.
Let me ask, how to custom engine config and use it in the Flowable?
Thanks!
Best regards,
Zholaman
I really need more info on what youāre doing in orde to help.
If youāre using an EmailTask and somethings goes wrong sending the email the execution fails an exception is logged.

Dear yvo,
I am using above settings (in flowable-task->flowable-ui-app.properties), also I tried to assign a task to some AD users (by flowable-task WEB UI), that is all I am doing.
I do not use āEmailTaskā, I do not know how to use it.
Please correct me if I am wrong, the Flowable should send a notification (to user email address) as soon as user get a task, is not it ?
Thank you for log example!
Best regards,
Zholaman
Hi
This is not something that works automatically.
It has to be either modeled in the process or implemented in a TaskListener or implemented in the Task App.

Yvo
Hi Yvo,
I got it, thanks a lot!

Hi, please i justa want to know where to find that configuration file?
In the docs under Configuration - here?
So where can i find flowable.cfg.xml file to configure
A quick search of the sources says here.
Hi Zholaman,
I have a similar requirement. I am creating a task say āātask 1ā which after completion goes to email task . I configured email task by providing to , from and subject on flowable-modeler UI. In āātask 1ā, i am providing a task listener with event ācompleteā and giving Expression āEmailā . But when i try to complete āātask 1ā, its gives internal server error and does not get completed. How to resolve this could you help.
Thanks in advance.
