Issue with camunda mail connector


Using Tomcat im getting this error : “cant find classpath:/”. There is in normal location resources/ just like pizza example.


Hi @Orestes_Febles,

can you please describe your deployment.
Where is your config properties located?

If you use a shared process engine (e.g. camunda tomcat distro) then you should put the config properties in the conf folder of the tomcat and set the environment variable to %CATALINA_HOME%\conf.

Note that it’s currently not possible to put the config properties in the process application.

Best regards,


Hi Philip, thanks for your answer. Im putting the in lib folder of tomcat and it works. But set the environment variable to %CATALINA_HOME%\conf?

Thanks again


Hi @Orestes_Febles,

usually, you will put all configuration files in the tomcat conf folder. So if you put the in this folder then you must set the MAIL_CONFIG environment variable.

Does this work for you?

Best regards,


It doesnt work for me … None of the examples (pizza and printer) shows a piece of code changing MAIL_CONFIG environment variable of de connector. Do you have some example?

Thanks again Philipp


Hi @Orestes_Febles,

if you use the tomcat disto then you can adjust the script start-camunda.bat / and set the environment variable MAIL_CONFIG to %CATALINA_HOME%\conf before calling the start script (i.e. /server/apache-tomcat-8.0.24/bin/startup.bat).

Does this help you?

Best regards,



Hi I think I’m facing thesame problem as orestes.

Error Message:
No connector found for connector id ‘mail-send’

I have the .properties file already in /server/apache-tomcat-8.0.24/conf so I think my problem is being caused by the startup.bat file(I dont really know how to perform the required changes). Here is what it currently looks like
