Spring MVC + Hibernate not doing anything to the DB, no exceptions thrown

Question

I'm at a loss for a solution. I've been playing with Spring MVC and Hibernate, and I had established a connection with my database, pulling data, no problem.

I added an @Entity, and maybe done some other changes, and now Hibernate won't do anything. By anything, I mean there is no SQL executed (as shown in the tomcat logs, using the show-sql option of hibernate). There is also no exceptions thrown at all, and Hibernate even tells me it has updated the DB schema (which it has not, since no tables have been created.).

I have checked that the getAllArticles() method gets called during runtime using a debugger.

I really don't know what to check now, if someone has any idea I'll be grateful forever.

Thank you !

Answer 1

Could be copy-paste, but your hibernate session factory bean is scanning com.test for hibernate entities instead of com.last.
