Can't fix error in Beginner Hibernate Program [duplicate]

This question already has answers here:
Invalid syntax error "type= MyISAM" in DDL generated by Hibernate
(7 answers)
Closed 2 years ago.
I've just started learning Hibernate, and attempted the example at https://www.javatpoint.com/example-to-create-hibernate-application-in-eclipse-ide , with slight modifications. I received a huge error log -

This is my POJO class -

public void setFirstName(String firstName) {

}
public void setLastName(String lastName) {

}

Finally, the class with the data manipulation functionality -

public class FunctionalityImplementer {
public static void main(String[] args) {
StandardServiceRegistry ssr = new StandardServiceRegistryBuilder().configure("hibernate.cfg.xml").build();
Metadata meta = new MetadataSources(ssr).getMetadataBuilder().build();
SessionFactory factory = meta.getSessionFactoryBuilder().build();
Session session = factory.openSession();
Transaction t = session.beginTransaction();
Employee e1 = new Employee();
e1.setId(1);
e1.setFirstName("Elon");
e1.setLastName("Musk");
session.save(e1);
t.commit();
System.out.println("Successfully saved");
factory.close();
session.close();
}
}
The mysql-connector-java-5.1.48-bin.jar file has been added to the classpath. So have all the other jars specified in the example I'm attempting.
Please let me know what the problem is.

It turned out the solution was there on StackOverflow, albeit under a different heading:
Invalid syntax error "type= MyISAM" in DDL generated by Hibernate
Long story short, change the dialect in hibernate.cfg.xml to org.hibernate.dialect.MySQL5Dialect and things will run fine.

hibernate throwing multiple errors at a time

I am a newbie in hibernate and I was trying to implement an application which could create a table on its own using hbm2ddl mapping but my Java application is throwing multiple errors at once.

Session session=sessionFactory.openSession();
session.beginTransaction();
session.save(teacher);
session.getTransaction().commit();
}catch(Exception ex){
}
}
}

}

}
}

Eclipse Project
PostgreSQL Database

Hibernate is trying to create entity in hibernatedemo schema. You need to create that schema in database. I did not see your configuration that is pointing to hibernatedemo schema. The cfg.xml is generated by MyEclipse Hibernate tools. Check that configuratioon.
How to create schema in PostGreSQL Link
CREATE SCHEMA IF NOT EXISTS schema_name
After creating schema try again to start your application

You can simply add that tag to your config xml file
<property name="hibernate.hbm2ddl.auto">update</property>

I have installed MySQL and its username is root and password is 2323
What is wrong?

Seems a typo to me,is your Mysql listening on port 33606
"jdbc:mysql://localhost:33606"
It should be (default,if you have not changed) 3306,please verify.
This may be the reason your are getting
Exception in thread "main" org.hibernate.exception.JDBCConnectionException: Error calling Driver#connect

Your actual error is
Communications link failure: The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
please check the below link, may help you.
Solving a "communications link failure" with JDBC and MySQL

If you're getting org.hibernate.exception.JDBCConnectionException: Error calling Driver#connect or Communications link failure then it means you're unable to connect to DB. It could be because of you may not be using the right driver or your database is not reachable. Here are few steps which can be used to identify the issue. You can refer this post for detail explanation.
IP address or hostname in JDBC URL is wrong.
Hostname in JDBC URL is not recognized by local DNS server.
Port number is missing or wrong in JDBC URL.
DB server is down.
DB server doesn't accept TCP/IP connections.
DB server has run out of connections.
Something in between Java and DB is blocking connections, e.g. a firewall or proxy.
To solve the one or the other, follow the following advices:
Verify and test them with ping.
Refresh DNS or use IP address in JDBC URL instead.
Verify it based on my.cnf of MySQL DB.
Start the DB.
Verify if mysqld is started without the --skip-networking option.
Restart the DB and fix your code accordingly that it closes connections in finally.
Disable firewall and/or configure firewall/proxy to allow/forward the port.
