Database configuration problem

[danielporter]

Hi there,

I'm trying to configure activiti to use PostgreSQL. I have Postgres running on a remote server at port 5432. I copy pasted the 3 db creation scripts into PgAdmin and ran them on a database named "activiti". I'm getting a long list of exceptions, of which I'm only posting part. The main part seems to be "Driver must not be null." I found another post (https://forums.activiti.org/content/change-dbproperties-mysql-issue) that says this is probably a database configuration issue. I'm looking at my database conf file and don't see what's wrong. I wonder if someone here could point me in the right direction. Following is the database conf and part of the error.

File db.properties:
db=postgres
jdbc.driver=org.postgres.Driver
jdbc.url=jdbcostgresql://server:5432/activiti
jdbc.username=postgres
jdbc.password=postgres

Error:
"org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'demoDataConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: protected org.activiti.engine.IdentityService org.activiti.explorer.conf.DemoDataConfiguration.identityService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'identityService' defined in class path resource [org/activiti/explorer/conf/ActivitiEngineConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.activiti.engine.IdentityService]: Factory method 'identityService' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngine' defined in class path resource [org/activiti/explorer/conf/ActivitiEngineConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.activiti.engine.ProcessEngine]: Factory method 'processEngine' threw exception; nested exception is java.lang.RuntimeException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngineFactoryBean': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: Driver must not be null

Hi,

Which activiti version do you use?

Regards

5.19.0.2. But after banging my head on this for three days, it turns out I was not specifying the name of the driver correctly: It should be org.postgresql.Driver and not org.postgres.Driver. Doh.
