Hello,

I am using camunda bpm in java application . I am using jython-standalone-2.5.2 as a dependency in pom.xml in maven project.
when I run the application in IDE the script is running without problems.
But when I run the application from command line using java -jar application.jar I get the following error:

org.camunda.bpm.engine.ScriptEvaluationException: Unable to evaluate script: ImportError: No module named re in <script> at line number 1

Hi,

how is your jython path configured. Is the re module part of it?

Cheers,

I didn’t do any configuration. Can you tell me the configurations that I need to make?
