This appears not to work per the instructions in the readme. After trying on two machines I get the same error.
ERROR 14 Sep 2011 14:35:21 org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'setupSessionFactory' defined in class path resource [KB:commonsApplicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Hibernate Dialect must be explicitly set
I ran the setup.sh and mysql is running. The password in the wflow/app_datasource-default.properties is correct and I tested that I can connect from the command line.
