Error in Activiti 5.3 Administrator under Tomcat

[mascaroni]

I installed Activiti 5.3 and all components are fine except the Activiti Administrator.

While invoking the activiti Administrator in activiti 5.3 under  Tomcat, I get the following error:
javax.servlet.ServletException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'adminApp': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: org.activiti.administrator.service.AuthenticationService org.activiti.administrator.AdminApp.authenticationService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'authenticationService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.activiti.engine.IdentityService org.activiti.administrator.service.AuthenticationServiceImpl.identityService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngine': FactoryBean threw exception on object creation; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is org.h2.jdbc.JdbcSQLException: Connection is broken: "session closed" [90067-132]

I assume you have changed the databaser of your demo setup?

The administrator app has its own config which must be updated separately.

Where can I find the configuration steps for the Administrator?

Administrator uses the Spring configuration, so look in the WEB-INF for the Spring config XML and change the database there.
