Right now, I am doing this EJB tutorial: http://programming.manessinger.com/tutorials/an-eclipse-glassfish-java-ee-6-tutorial/#heading_toc_j_23 , but instead of GlassFish I use JBoss 7.0, and instead of DerbyDB I use PostgreSQL and Hibernate as persistence provider. My problem is, that I can’t deploy the EAR and test the webservices (this is where I am in that tutorial ATM), because JBoss gives me following error:
ERROR [org.jboss.msc.service.fail] (MSC service thread 1-7) MSC00001: Failed to start service jboss.persistenceunit."JEETutorialEAR.ear/JEETutorialEJB.jar#JEETutorialEJB": org.jboss.msc.service.StartException in service jboss.persistenceunit."JEETutorialEAR.ear/JEETutorialEJB.jar#JEETutorialEJB": Failed to start service

I have PostgreSQL JDBC driver added in project path. And I did, what is advised here: http://jan.zawodny.pl/blog/2011/07/jboss-7-postgresql-9 sans datasource configuration (I guess that is done by Eclipse during starting-up the server).
You need to manually deploy the driver e.g. in standalone mode by copying it into
$JBOSS/standalone/deployments/ . There is no need to package it as a module.
In future versions of AS7.1 it will be possible to use the classical -ds.xml files again for creating datasources. But that is only a comment 🙂
