Hibernate says database.table doesn't exist

The Situation
Ok, so I am learning Hibernate(from 2 days so pardon any blunder), I am using mysql database and just trying tocreate a table Employee and make an entry in database(A demonstration).
Here are the codes
POJO:
package com.sopra.pojo;
import javax.persistence.*;
#Entity
#Table(name = "EMPLOYEE")
public class Employee {
#Id
private int Id;
private String firstName;
private String lastName;
private int salary;
public int getId() {
return Id;
}
public void setId(int id) {
Id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public int getSalary() {
return salary;
}
public void setSalary(int salary) {
this.salary = salary;
}
}
hibernate.cfg.xml which is in src
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.org/dtd/hibernate-configuration-3.0.dtd">

EmployeeDBManager.java
package com.sopra.pojo;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class EmployeeDBManager {
public static void main(String[] args) {
Employee e = new Employee();
e.setFirstName("Salim");
e.setId(672);
e.setLastName("Shamim");
e.setSalary(266);
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
session.persist(e);
tx.commit();
session.close();
}
}
The Error
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'test.employee' doesn't exist
I've tried
use this in cfg file : <property name="hibernate.hbm2ddl.auto">update</property>
What is interesting is when I manually create the table in mysql using workbench, hibernate does drops it as when i use drop command it says the table doesn't exists.
I can't figure out where the glitch might be(newbie and internet didn't helped).
Please mention any additional details required in comments.
Please help!
Thanks.

I made it worked, I am not sure if it's a proper answer but since it got it working I am posting it as an answer.
I made two changes
I was using hibernate version 5.2.12 so I changed it to 4.2.0 and added jars from two more folders which earlier I hadn't (In summary I have now imported Jars from :optional, provided & required folder in hibernate user library)
I overlooked a url mistake which was
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.org/dtd/hibernate-configuration-3.0.dtd">
In the dtd url I have not added www. It should have been
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">`
So, my mistake.
Anyway, comments regarding improving this answer and why it made it work are deeply appreciated.

add different auto option of hibernate,
Use instead of create , update or create-drop
<property name="hibernate.hbm2ddl.auto">update</property>
or
<property name="hibernate.hbm2ddl.auto">create-drop</property>

org.hibernate.exception.JDBCConnectionException: Cannot open connection

for testing purpose i wrote very small code,which repeatedly throws exception related to jdbc driver.
package sally;
import org.hibernate.Session;
import org.hibernate.Transaction;
public class MainClass {
public static void main(String args[]){
try{
Session session=HibernateUtil.getSession();
Transaction tx=session.beginTransaction();
Employee ee=new Employee("abx","asd",2000);
session.save(ee);
tx.commit();
}catch(Exception e){
e.printStackTrace();
}
}
}
This is my ben/pojo class for mapping
package sally;
public class Employee {
private int id;
private String firstName;
private String lastName;
private int salary;
public Employee() {}
public Employee(String fname, String lname, int salary) {
this.firstName = fname;
this.lastName = lname;
this.salary = salary;
}
public int getId() {
return id;
}
public void setId( int id ) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName( String first_name ) {
this.firstName = first_name;
}
public String getLastName() {
return lastName;
}
public void setLastName( String last_name ) {
this.lastName = last_name;
}
public int getSalary() {
return salary;
}
public void setSalary( int salary ) {
this.salary = salary;
}
}

can any body tell whats wrong here???
this is db column list : first_name last_name salary.

You need to put the mysql JDBC driver JAR on your classpath

name for the driver class must be updated as well as server time zone (for me this is insane but it has to be done

Hibernate tutorial. Connection refused: connect

I want to learn how Hibernate works, so found this tutorial. But i get this error:

I found out, that many people have the same issue with the same tutorial. For example link, or another link.
Another issue is, that it takes far to long to show the error after starting the programm(40 sek).
Here is my main class:
package mypackage;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;

public class StoreData {

// creating seession factory object

// creating session object
Session session = factory.openSession();
// creating transaction object
Transaction transaction = session.beginTransaction();
Employee e1 = new Employee();
e1.setId(115);
e1.setFirstName("Elvis");
e1.setLastName("Presley");
session.persist(e1);// persisting the object
transaction.commit();// transaction is committed
session.close();
System.out.println("successfully saved");
}catch (HibernateException ex) {
ex.printStackTrace();

And this are my jars and all files.
Someone knows what is the issue here?

in your Hibernate configuration file, mapping is commented, and
<property name="hibernate.hbm2ddl.auto">create_drop</property>
is supposed to be update, not create_drop

I was facing the same error. In my case with another hibernate maven tutorial, I just forgot to run the service like this:
mvn exec:java -Dexec.mainClass="org.hsqldb.Server" -Dexec.args="-database.0 file:target/data/tutorial"

how to resolve ==> org.hibernate.exception.GenericJDBCException: Could not open connection

when i execute my Main class i get this execution
cant figure out the issue point
the error comes in the line

I believe you need to reset your database password. Follow this link to do the same:
http://dev.mysql.com/doc/refman/5.1/en/resetting-permissions.html
or the user priviliges are not correct. Follow this to set priviliges:
