Hi

The Error log is not enough to find the mistake.

Can you add the whole Error log.

Hi,

Which version of alfresco you are using? . From Alfresco 4.0 Activity is by default Workflow Engine, to use JBPM you need to enable it.

Thanks,
Vandana

This is how I enabled jbpm workflows in 4.2.b©

file: alfresco-global.properties

#enable jbpm
system.workflow.engine.jbpm.definitions.visible=true
system.workflow.engine.jbpm.enabled=true
