None of the other solution worked for me.

Even if I don't think its the best practice, I Had to add it into the code like this

configuration.addAnnotatedClass(com.myOrg.entities.Person.class);

here

public static SessionFactory getSessionFactory() {
    Configuration configuration = new Configuration().configure();

    configuration.addAnnotatedClass(com.myOrg.entities.Person.class);

    StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
            .applySettings(configuration.getProperties());
    SessionFactory sessionFactory = configuration.buildSessionFactory(builder.build());
    return sessionFactory;
}

It means your table is not mapped to the JPA  Either Name of the table is wrong  Maybe case sensitive   or you need to put an entry in the XML file   Happy Coding

If you are using the JPA annotations to create the entities and then make sure that the table name is mapped along with  Table annotation instead of  Entity   Incorrectly mapped     Entity name  DB TABLE NAME   public class DbTableName implements Serializable                       Correctly mapped entity     Entity  Table name  DB TABLE NAME   public class DbTableName implements Serializable

If you by any chance using java for configuration  you may need to check the below bean declaration if you have package level changes  Eg  com abc spring package changed to com bbc spring     Bean     public SessionFactory sessionFactory              LocalSessionFactoryBuilder builder   new LocalSessionFactoryBuilder dataSource               builder scanPackages  com abc spring         Comment this line as this package no longer valid          builder scanPackages  com bbc spring            builder addProperties getHibernationProperties              return builder buildSessionFactory

Another solution that worked   The data access object that actually throwed this exception is  public List lt Foo gt  findAll         return sessionFactory getCurrentSession   createQuery  from foo   list        The mistake I did in the above snippet is that I have used the table name foo inside createQuery  Instead  I got to use Foo  the actual class name   public List lt Foo gt  findAll         return sessionFactory getCurrentSession   createQuery  from Foo   list      Thanks to this blog  https   www arundhaj com blog querysyntaxexception-not-mapped html

In Apache Derby DB  refrain from using table names as  user  or so because they are reserved keywords on Apache Derby but will work fine on MySql   In the Query  you must specify the name of the Entity class that you want to fetch the data from in the FROM clause of the Query   List lt User gt  users session createQuery  from User   list      Here  User is the name of my Java Entity class Consider the casing of the name as in Java it matters

There is one more chance to get this exception even we used class name i e   if we have two classes with same name in different packages  we ll get this problem    I think hibernate may get ambiguity and throws this exception  so the solution is to use complete qualified name like com test Customerv   I added this answer that will help in scenario as I mentioned  I got the same scenario got stuck for some time
