I’m sure that many hours must have been spent by Spring/Hibernate users trying to figure out why they are getting the table not mapped exception when they are sure that have mapped the table. Well the problem can be fixed if you take care of the case (upper vs. lower case). Suppose that the name of your table is user and the name of the your class is User.Here is the crux of the problem:This is the wrong version that leads to the not mapped exception:getHibernateTemplate().find("from user");Here is the correct version:getHibernateTemplate().find("from User");You see the problem is that in the hibernate version of the SQL, you are expected to use the name of your class and not the name of the table. Typically, the name of the table is all in lowercase and the name of the class starts with an uppercase. Yep programming can be very frustrating.
