Question

I am using hibernate as ORM when i checked my logs (catalina.out)

I am getting this warning so many times

WARN   (org.hibernate.jdbc.JDBCContext:333) - afterTransactionCompletion() was never called

Can any one please help me to solve this warning…?

what is the meaning of that warning and when it occurs ??

Answer 1

In the file JDBCContext.java source file is the following comment

/**
 * We cannot rely upon this method being called! It is only
 * called if we are using Hibernate Transaction API.
 */

This means, the method afterTransactionCompletion() normally is called by the hibernate transaction API, for example Session.flush() or Transaction.commit(). It seems somewhere in your program it can happen a transaction is not ended regularly. We can’t tell you where, because we don’t know your code.
