SLF4J error

sarra1 — Wed, 19 Jun 2013 14:17:26 GMT

I tried to follow the instructions, (Activiti in action) to deploy A book order process with a script and user task, but when I run the BookOrderTest.java ; nothing works :———–SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".SLF4J: Defaulting to no-operation (NOP) logger implementatio

That doesn't look like an SLF4J error, it just states you have no logger configured and it's defaulting to the No-op logger. You need to configure a bridge to get more logging info. You can find info about this here: http://activiti.org/userguide/index.html#loggingConfiguration

The problem seems to be you have no Activiti tables in your database: "no activiti tables in db"

To fix that, you need to either run the database scripts that are packaged in the activiti-engine module here https://github.com/Activiti/Activiti/tree/master/modules/activiti-engine/src/main/resources/org/activiti/db/create

or you can set the databaseSchemaUpdate to true in the processEngineConfiguration. This is documented in the userguide. Beware: this option will try to create the database tables itself. I obviously don't know your database setup and policies for that kind of stuff, so pick the option that suits you best.
