ClassNotFoundException thrown by Hibernate buildSessionFactory

ClassNotFoundException thrown by Hibernate buildSessionFactory - java

I am learning hibernate for the first time so unable to find the error.
The student007 table is created in the database then i executed the client class. By analyzing the error what i understand is there is a problem with the sessionfactory part. also there is an error with the oracle driver saying class not found exception
student.hbm.xml

The exception message says it all: Could not load requested class : oracle.jdbc.oracleDriver
So the first thing I check if you misspelled the name of the driver and you really do. The class names starts with upper-case letters.
The correct name of the driver should be: oracle.jdbc.OracleDriver.

How to fix the error "INFO: HHH000206: hibernate.properties not found"

I tried to test whether the hibernate configuration is working properly. I tried, but I got an error:
INFO: HHH000206: hibernate.properties not found
To do this, first I made, hibernate.cfg.xml file as follows:

So, when I run this test class, I get an exception. The hibernate.cfg.xml file is also in main/resources path. I am not able to figure out the problem.
I already tried going through this and other links having same problem: how to fix the error: "INFO: HHH000206: hibernate.properties not found"?
And my output after running the program is:

I do not know if there is error in hibernate.cfg.xml. I am not being able to figure it out.

org.springframework.beans.factory.BeanCreationException: error in creating factory bean

I am new to Spring and while setting all the bean for spring orm configuration, I am getting this error: org.springframework.beans.factory.BeanCreationException

Could not instantiate persister org.hibernate.persister.entity.JoinedSubclassEntityPersister

I am getting the following error while trying to connect to mysql using hibernate. I have a Super class Employee and three subclasses: SoftwareEmployee, HardWareEmployee and Admin.I also have two xml files: hibernateisapersubclass.cfg.xml and employeeisapersubclass.hbm.xml. I am trying to populate data in 4 different table using 'joined-subclass' tag in my xml. Please help.

hibernate 5.2.2: ManyToOne first example

the system that I'm implementing is composed of:
Eclipse Neon 4.6 + maven (integreted) + Hibernate 5.2.2 + Mysql (i use MySql Workbench 6.3)
algorithm:
I tried to create this java application on eclipse:
a student entity and an address entity (the some address can be used for many students)
info:
I created only a htmanytoone schemas on mysql, and I want hibernate it to take care of creation and management of the entities on.
I hope there are no problems of continuity (I modified the code several times )
My project on eclipse:
Package Explorer
Student.java:
package withMaven.hibernateMaven1;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
#Entity
#Table(name = "student")
public class Student {
private long studentId;
private String studentName;
private Address studentAddress;
public Student() {
}
public Student(String studentName, Address studentAddress) {
this.studentName = studentName;
this.studentAddress = studentAddress;
}
#Id
#GeneratedValue
#Column(name = "student_id")
public long getStudentId() {
return this.studentId;
}
public void setStudentId(long studentId) {
this.studentId = studentId;
}
#Column(name = "student_name")//, nullable = false, length = 100)
public String getStudentName() {
return this.studentName;
}
public void setStudentName(String studentName) {
this.studentName = studentName;
}

If you want to use mysql, you have to Change this lines:
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost/htmanytoone?useSSL=false</property>

Guys I am new with Hibernate and I am struggling to make a hello world app work. Below I will post the exception I am getting as well as my code - with the hope maybe someone can spot other errors which I have and save me from "future" troubles.
Code:
package org.arpit.javapostsforlearning;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
#Entity(name = "User_table")
public class User {
#Id
int userId;
#Column(name = "User_Name")
String userName;
String userMessage;
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;
}
public String getUserMessage() {
return userMessage;
}
public void setUserMessage(String userMessage) {
this.userMessage = userMessage;
}
}
This:
package org.arpit.javapostsforlearning;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
public class HibernateMain {
public static void main(String[] args)
{
Configuration configuration=new Configuration();
configuration.configure();
configuration.addClass(org.arpit.javapostsforlearning.User.class);
ServiceRegistry sr= new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
SessionFactory sf=configuration.buildSessionFactory(sr);
User user1=new User();
user1.setUserName("Arpit");
user1.setUserMessage("Hello world from arpit");
User user2=new User();
user2.setUserName("Ankita");
user2.setUserMessage("Hello world from ankita");
Session ss=sf.openSession();
ss.beginTransaction(); //saving objects to session
ss.save(user1);
ss.save(user2);
ss.getTransaction().commit();
ss.close();
}
}

Here is also screen shot of my App

Take a look to: <mapping class="User.hbm.xml"/>. But you using resource. You are able to use class when you saying that map me class for that, but you want to map resource. So just use
<mapping resource="User.hbm.xml"/>

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

ClassNotFoundException thrown by Hibernate buildSessionFactory - java

The exception message says it all: Could not load requested class : oracle.jdbc.oracleDriver So the first thing I check if you misspelled the name of the driver and you really do. The class names starts with upper-case letters. The correct name of the driver should be: oracle.jdbc.OracleDriver.
