Cannot connect to Informix using Hibernate

I'm trying to connect to Informix database using Hibernate 5.2.10, but the program doesn't respond and gets stuck without throwing any error message.
I can't find anything from the console . Any suggest on what mistake I made? I'm new to Hibernate
hibernate.cfg.xml

}

I did a quick test with 5.2 and the latest jdbc driver and it appears to work fine for me. I'm using your HiberanateUtil and a similar Hibernate config file:

Only way I get something like a 'hang' is if I get an exception during the open session(). I forced one compiling the method with an old Hibernate version library (3.x) which doesn't have 'classic' methods:

As yours, 'last' INFO message is "Connection obtained from JdbcConnectionAccess" , but after that I'm also getting the nosuchmethod exception. I have to press control+c to get out.
Maybe your exceptions are been sent somewhere else ;)
EDIT
This is the code I'm using to test it directly from the console, should be everything you need to run it.

Thanks for trying to help me out. The issue got resolved after I removed this property from hibernate config file.

Hibernate, data is not inserting into table

I'm a newbie to hibernate. I'm trying to insert data into table. It's only creating the tables but not inserting the data into table. I'm not sure where I'm doing wrong.
Any help would be appreciable.
UserDetails:
package org.com.etown.onetoone;

import javax.persistence.GeneratedValue;

#Id #GeneratedValue(strategy = GenerationType.AUTO)
private int userid;
private String userName;
public int getUserid() {
return userid;
}
public void setUserid(int userid) {
this.userid = userid;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}

Change
#GeneratedValue(strategy = GenerationType.AUTO)
To
#GeneratedValue(strategy = GenerationType.IDENTITY)
I am not sure , but it will work I think.
Edit
AUTO Indicates that the persistence provider should pick an
appropriate strategy for the particular database.
IDENTITY Indicates that the persistence provider must assign primary
keys for the entity using database identity column.
SEQUENCE Indicates that the persistence provider must assign primary
keys for the entity using database sequence column.
TABLE Indicates that the persistence provider must assign primary keys
for the entity using an underlying database table to ensure
uniqueness. Refer to the API here
http://docs.oracle.com/javaee/5/api/javax/persistence/GenerationType.html

Table created but not visible in database while using hibernate

application wizard
SQL command prompt ---showing account locked because of repeated wrong passwords, which is working fine in application wizard.
Everything seems to be right even in log info it is showing the table is created and data is inserted on the same, but I am unable to see the table and data in database.Can anybody suggest the possible reason.

Hibernate working with queries

Started to learn hibernate. Doing everything by tutorial, but when I try to do simple select, nothing happens. Сan't understand what the problem is.

As far as I remember, the newer version of hibernate do not support <mapping class= .../> in the hibernate configuration file any longer.
Can you remove that and instead try with
cfg.addAnnotatedClass(User.class) in your HibernateUtil static block.
On a different note, you may want to consider using the latest approach of building the sessionFactory as Configuration way is deprecated. Refer to Native Bootstrapping section for more information.

May be nothing in data base for Users table.First Insert some data. Then check.

Check user exists in database using hibernate

I am new in hibernate
I have a UserDAO class and a method to determine whether user exists in a specific table or not.
This is my users table in hb3 database:
And this is my class:
public static void main(String[] args) {
System.out.println(userExistsinDB("ABC"));
}
public static boolean userExistsinDB(String username) {
String queryStr = "Select * from users where username=" + username; // since username is unique
SessionFactory sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
Query query = session.createSQLQuery(queryStr);
System.out.println(query.getFirstResult());
session.getTransaction().commit();
session.close();
sessionFactory.close();
return false;
}
But the result is null in query.getFirstResult() , Why?
I have ABC username in users table.

Try this:
org.hibernate.Query query = session.createQuery("from users where username = :username");
query.setParameter("username", username);
query.uniqueResult();

You should use parameterized query. It returns null because string literals should be enclosed by quote notation.
