Eclipse: connecting and configuring Hibernate

Question

I'm new to eclipse. I'm trying to work with Hibernate. Java ee IDE version Juno , and Hibernate Tools version 3.5.1. In Database Development of the IDE i've created a a data source, and tested the connection, and it works fine. Then I have created a Hibernate configuration file hibernate.cfg.xml Then I have created a Hibernate console configuration When i try to refresh the console configuration or when i try to create the reverse engineering file i have the error "An internal error occurred during : Fetching children of TestHiber01. plugin org.eclipse.core.jobs. All the error log is :

The hibernate.cfg file is:

<session-factory>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.password">XXXXX</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mydb</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
</session-factory>

What does it mean? Why can't connect to the database?

Hibernate Tools 3.5.1 depends on Eclipse Indigo. You have hit a compatibility issue.

When I use the JBoss Juno update site, I see this version of Hibernate Tools available for installation: Hibernate Tools 3.6.0.Alpha1-v20120910-1507-H32. Here is the corresponding JBoss issue.
