I apologize in advance for being a complete Hibernate newb, but the library I'm using for a project uses hibernate in the background for its persistence.
The library is is JBoss JBPM 3.1.4, though I'm using the library without JBoss. It's using hibernate 3.1, connecting to a MySQL db. Connection parameters in hibernate.xfg.xml are as follows:
Code:
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://xxx.xxx.xxx.xxx:3306/db</property>
<property name="hibernate.connection.username">user</property>
<property name="hibernate.connection.password">pass</property>
Everything works just fine when I run my project in Eclipse. I haven't had any connection problems since I started the project. When I export my project to a jar and run it on the command line, though, I suddenly get an exception that suggest a datasource problem.
Code:

Exception in thread "main" org.hibernate.HibernateException: Could not find datasource
Output from the same spot when it runs successfully in eclipse:

To my untrained eye it looks like it could be a configuration problem, since it seems to be either not finding the datasource that's configured for the project or trying to use the wrong datasource.
Any suggestions would be greatly appreciated.
