I 'm having problems with service tasks in activiti

[gabriel_segall1]

Hello , I 'm having problems with service tasks in activiti. My goal is to use the CMIS Alfresco api in a task service . But whenever I run the process the following message appears "couldn't instantiate class org.alfresco.repo.workflow.activiti.listener.ScriptExecutionListener".

I already put the .jar files in the WEB- INF / lib folder .

Can someone help me?

org.alfresco.repo -> that's an Alfresco class. Only runnable in Alfresco.
