Could not update Activiti database schema: unknown version from database

[shuchi]

Hi,

I am using Spring container to initialize process engine but when I start my tomcat server, I get the following exception:

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngine': FactoryBean threw exception on object creation; nested exception is org.activiti.engine.ActivitiException: Could not update Activiti database schema: unknown version from database: '5.16.4.0'

Are you testing on an existing database? Which version of the Activiti Engine JAR are you using?

Best regards,

I got this also when I started playing around with activiti (for the first time last week). I had two versions of activiti jar (5.14 and 5.16).
As luck would have it, i ran the scripts from 5.16.. but deployed 5.14.

To see which one your database is built for
<code>
select * from ACT_GE_PROPERTY where name_ = 'schema.version';
</code>

hope this helps
