Error in Sending Email Task using connector Id "mail-send"

Tushar · March 15, 2017, 12:11pm

Hi,

I am trying to send an email notification during a process. Seeing the pizza example I implemented a service task as below

but I am getting an error while initiating this task as below:

Hi Tushar,

Did you follow the Install and How to use it? sections of the mail connector documentation?

Tushar · March 16, 2017, 5:19am

Yes I followed it…a jar was missing in lib folder…I added it so that issue got resolved…
but after that new error came up while starting the process…
The process could not be started. :
Cannot find mail configuration at: classpath:/mail-config.properties

but I have added “mail-config.properties” file in src/main/resources location as shown in pizza mail example and nowhere in that sample its mentioned to define classpath:/mail-config.properties as it is a default one.

Can you help?

Regards,
Tushar

Philipp_Ossler · March 16, 2017, 7:09am

Hi Tushar,

the documentation of the pizza examples says that you must copy this config file to the application server config folder. In case of tomcat, this is server\apache-tomcat-8.0.24\conf.

That means you have one config for all applications if you use a shared process engine.

Does this help you?

Best regards,
Philipp

Tushar · March 16, 2017, 7:11am

I have copied the mail-config.properties file to “conf” folder also…
and have created Environment Variable : “MAIL_CONFIG” in my docker container…but still I am facing the same issue…

Regards,
Tushar

Philipp_Ossler · March 16, 2017, 7:24am

Hi Tushar,

please make sure that you set the env variable at the right place. For me, it work when I set the env var in the start-camunda.bat script.

set "MAIL_CONFIG=%CATALINA_HOME%\conf\mail-config.properties"

Best regards,
Philipp

Tushar · March 16, 2017, 11:58am

Hi Philipp,

I have added the environment variable as
MAIL_CONFIG=“$CATALINA_HOME/conf/mail-config.properties” in my Container’s bin/catalina.sh file (which starts my camunda server in the container)
I have copied mail-config.properties file to conf folder also.
I have same mail-config.properties file in my src/main/resources folder also.

Still I am getting error as :

Hi Tushar,

do you export the env variable via

export MAIL_CONFIG="$CATALINA_HOME/conf/mail-config.properties"

?

Tushar · March 16, 2017, 1:04pm

I put it without export…after ur post…I added the export and that error got resolved…

but after that a new error came

Hi Tushar,

this sound’s odd. Do you use the Camunda distribution? Which version?

Best regards,
Philipp

Tushar · March 17, 2017, 8:42am

I am using camunda 7.6.0

Philipp_Ossler · March 20, 2017, 7:21am

Hi Tushar,

maybe this is not caused by the extension directly. Can you try to send a mail without the extension? For example using Java Mail.

Best regards,
Philipp

radovan · May 10, 2017, 7:12am

Hi Philipp,

where to set env variables if I’m running Tomcat as a service?

Philipp_Ossler · May 10, 2017, 1:00pm

Hi @radovan,

I didn’t try it out yet.

What system do you use? (win/linux)

Maybe you can find an answer on

Best regards,
Philipp

pithvajignesh · June 23, 2017, 6:09pm

Hi Tushar,

Have you had you resolve this error because right now I am getting the same error.
PFB snapshot.

If any solution for this problem please suggest.

Thank you,
Jignesh Pithva.

Tushar · September 5, 2017, 12:31pm

Do you have mail-config.properties file in your src/main/resources location of workspace???

Asaf_Shakarzy · November 16, 2017, 7:17am

You need javax.mail-1.5.5.jar,

Put it under camunda-7.x.x/server/apache-tomcat-8.x.xx/lib

(If still not working, remove other mail*.jar)

adat · January 3, 2018, 4:54pm

I have the text emails going through fine, but html is not going through. Any idea how to get this working?

adat · January 9, 2018, 5:23pm
