Using ProM within a Docker container

NiceNick

Hello,

I'm running a script (using ProM CLI) that takes as input a CSV file, mines it with HeuristicsMiner and exports the result as a BPMN file.

I created a directory with the ProM Framework + packages and altered the ProM.ini file to fetch the packages from this new directory. When I start the script everything works perfectly, but when I run the container I get the following:

Start plug-in BPMN XML 2.0 export

Can anyone help me with this issue, please?

Best regards.

Does anyone have an idea how to fix this? I've tried X11 Forwarding, VNC server and about everything I can find on this topic and nothing works.

Best regards.

HI,

You can try to provide the BPMN export plug-in a null context instead of your regular CLI context. If provided a regular context, this plug-in will try to visualize a BPMN diagram to obtain graphical information like positions and such. This visualization throws an exception in your case, so you want to avoid it. If provided a null context, it will avoid it. Of course, there will then be no positions and such in the exported BPMN file.

Kind regards,

Eric.

Thanks for your answer hverbeek!
It helped me a lot.
