Hello,

When I make the following call:

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

I get the following exception:

Initial SessionFactory creation failed.java.lang.ClassCastException: org.hibernate.type.StringType cannot be cast to org.hibernate.type.VersionType
Exception in thread "main" java.lang.ExceptionInInitializerError

at util.HibernateUtil.<clinit>(HibernateUtil.java:17)

Anyone have any ideas why this is happening and how I can fix it?

I am new to Hibernate, and I am just trying to get a feel for it. I used the Hibernate Tools for Eclipse to generate my POJO's from a small simple database. However I cannot get base the first step of getting a SessionFactory.

Also, being new, I am finding Hibernate difficult to get a handle on and working. I am used to just using JDBC and SQL. I never had to mess with XML or what not. I am willing to go through the pain of learning because it supposed to make my life easier in the long run, however the pain of learning is getting pretty high.

Any help is appreciated, Thanks...

Looks like you are trying to map some string to a version type column. Maybe it's wrong configuration mapping file, or wrong class definition.

Yeah I can read the exception too, however, as I stated, this was all autogenerated by the Hibernate Eclipse Tools plugin. Since (1) it is autogenerated code or XML and you should never modify autogenerated code, and (2) it doesn't say what mapping, or table/column is having the problem, so I cannot even verify where the problem is in the autogenerated code or XML to begin with, so cannot provide much more info that I provided in the orignal post.

I haven't created anything by hand except for the class with the main method and it cannot get past the first time.

So, either the autogeneration tool doesn't work or has bugs, or something else is wrong.

Ah sorry, I have no experience with this autogeneration tools.
