NoSuchMethodError: openSession() while migrating Hibernate

Question

I'm doing Hibernate migration.

Just changed Hibernate.3.jar to Hibernate.4.3.1.jar which gave me 2 errors

1)Why Hibernate STRING can not be resolved?

2)While calling sessionFactory.openSession()

java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/Session;

Did research and found the link

java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session

But the I'm not using Spring in my project and it's plain hibernate. Still the error exists .. Any help or Idea on this ?

Thanks for any clue.

I imagine the error is the same _`SessionFactory.openSession` no longer returns an `org.hibernate.classic.Session`, rather it returns an `org.hibernate.Session`_. If you control the class `com.nextenders.other.HibernateFactory` you will need to refactor it. If you do not you will need to revert to Hibernate < 3.6. This many break **loads** of things if you were referring to `Session` by the previous package in other places. — Boris the Spider, Feb 12 '14 at 11:42
@BoristheSpider Then It would be an compile time error right ? — Suresh Atta, Feb 12 '14 at 11:53
Yes. Unless you have something fishy going on, like compiling against different versions of libraries. I have had that a few times in Maven (for example) when there are dependency clashes. — Boris the Spider, Feb 12 '14 at 11:59

Really weird as Boris pointed.

I just deleted Hibernate3.jar from lib folder and done.

What happened so far is I just removed Hibernate3.jar from classpath and not deleted it. Actually there is no need to delete it, Since I disconnected it from classpath. Even after I clean the project it still pointing to same old jar. After the deletion of that jar, it's working fine.

It's compiled with HIbernate4.3.jar and running with Hibernate3.jar . So incompatibilty as pointed in Docs of NoSuchMethodError

Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.
