PostgreSQL - empty database - install.demo.db does not exist

created by wishmaster7 in jBPM - View the full discussion

Hello everybody,

 

I have downloaded the last version of jBPM (5.4.0), unzipped it, launched "ant install.demo", installed a local PostgreSQL database and follow the documentation to create the database with the matching user and configured jBPM to connect to this database. At the end of "3.7.3 Quickstart", when I want to reinstall the demo, it says BUILD FAILED - target "install.demo.db" does not exist in the project "jBPM.install".

 

At this point, I have a database called "jbpm5" with a user called "jbpm5", and a database called "task" with a user called "task". But they are empty. Then I launch Eclipse, create a new jBPM project with "a more advanced process including human task and persistence", and when I run the testProcess() method of the jUnit test class, it gives me an error ending by :

I think the problem comes from the missing "install.demo.db" task in the ant file. I've searched if a script exists to create the tables in my database, but found nothing.

 

Could someone please tell me what I have to do to create the required tables and sequences? Or, if I'm totally wrong, where is the problem?
