hibernate.dialect=org.hibernate.dialect.MySQLDialect

Seems that form engine tables were not created

Are you using an existing schema or letting Activiti create the tables?

Hello, thanks for your response.

Yes, I let Activiti create the tables. I only created a user that has access to the activiti database and linked its credentials in the activiti-app.properties file.

I replaced the H2 configuration with MySQL for Hibernate as you pointed me and re-executed tomcat and now, the databases are correctly linked !

In the db.properties from activiti-rest, there wasn't any definition of Hibernate for H2 in the demo. Should I add the same MySQL configuration as for activiti-app ?

No that's not needed for activiti-rest since it doesn't use Hibernate. Is all working fine now?
