Hi,
I'm trying to use reverse engineering to generate the POJOs, XML, DAO, and so on, and when I run Hibernate Code Generation shows me the following error message:

org.hibernate.console.HibernateConsoleRuntimeException: Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class

with the following stack trace:

... 6 more


I have installed on my computer:
- Eclipse Luna
- Apache Tomcat v7.0
- Struts2
- Hibernate Tools.
- Libraries hibernate: I tried 3.6 i 4.3
- Use the SGDB PostgreSQL 9.3

I have also tried to delete the Hibernate libraries and only had the Hibernate Tools but still gives the same error.
Even just leaving the Hibernate3 and JDBC driver library for PostgreSQL


I would appreciate help solving this.
Thank you.
