Camunda Cycle installation

radovan · November 16, 2017, 10:15am

Hello all,

I’m running Camunda 7.7.0 on Tomcat as service.
I tried to install Cycle but it doesn’t work.

Steps I did:

Created MS SQL database and tables with script
Added cycle to webapps
Modified \webapps\cycle\META-INF\context to my SQL datasource

Is anything more needed?

Catalina output below. There is some problem - Failed to read candidate component class.
How to fix that?

When I remove camunda-bpm-mail-core-1.1.0.jar from lib then it start properly.
But I need that library for sending emails. Is there any problem with configuration?

Matthijs_Burke · November 16, 2017, 11:52am

Hi @radovan,
please note that Cycle is a separate webapp and we don’t recommend to deploy it together with the other Camunda BPM platform components.

For details, see the User Guide and the Installation Guide.

Hope this helps.

Best regards,
Mat

I followed installation guide.
I don’t understand why is there problem with the library. Does Cycle use this library?

I know it’s separate webapp. But it’s not possible to run more webapps with Tomcat?
So I need to have another instance of Tomcat running for Cycle?
