Hi,

I'm currently trying to use JBPM 4.1 on tomcat with struts and mysql. I have a problem during the initialization of ProcessEngine. There is a connection time out exception. I think it is trying to connect to mysql but mysql is running and responding so I don't know what is going wrong.

Tomcat Log :
Le serveur a rencontré une erreur interne () qui l'a empêché de satisfaire la requête.
