Hibernate version: 3.0rc1
Eclipse 3.1m5
hibernate-tools-3.0alpha1.tar.gz
Database: mysql 3.23.58

Hi you all. I've got a problem with using hibernate-tools-3.0alpha1.tar.gz. The first and unsigninficant part is that when I try to save hibernate.cfg.xml file and an error shows up: "SaveFailed: Null". After that the file is saved however I can't understand where whis error comes from.

The worse thing is that I hava one ohter error which prevents me of using "Hibernate Artifact Generator". OK, I use the pluging from hibernate-tools and create a hibernate.cfg.xml file. After that I want to generate some hbm.xml files for the classes I have. However when try to do it this error comes:

Error under artifact generation
Reason:
org.hibernate.console.HibernateConsoleRuntimeException: problems while loading databse driverclass (org.gjt.mm.mysql.Driver)


Any ides how to fix this?

I have the same problem.

I'm running Eclipse 3.1M6.

My bad, checked again. I didn't add the Oracle Driver jar in the conf

i also have this problem when i create hibernate Reverse engineering file.
i have checked the classpath

org.hibernate.console.HibernateConsoleRuntimeException: Problems while loading database driverclass (oracle.jdbc.driver.OracleDriver)
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

please help me, thanks

so did you do the same as the previous solution ? Rememebering to add the jdbc drivers to the console configuration classpath ?
