I think you forgot to include the hibernate.jar in the lib directory.

I was doing permutation and combination. There were so many class not found errors. With hibernate3.jar included the error coming is


org.hibernate.HibernateException: Dialect class not found: class org.hibernate.dialect.MySQL5InnoDBDialect



<property name="databasePlatform" value="class org.hibernate.dialect.MySQL5InnoDBDialect"/>

since you suffer from library problems, maven will serve you very well.

Yes i will Try Maven but i did not think it would be such a mess trying tie all these 3 together. I am seeing the dialect class being present in Hibernate3.jar and not being picked up

Strange and frustrating :)
