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.
//Main Class

// TODO Auto-generated method stub
try{
Teacher teacher=new Teacher();
teacher.setName("abc");
SessionFactory sessionFactory=new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
Session session=sessionFactory.openSession();
session.beginTransaction();
session.save(teacher);
session.getTransaction().commit();
}catch(Exception ex){
}
}
}
//POJO Class
import javax.persistence.*;
#Entity
#Table(name="xyz")
public class Teacher {

}

}
}

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.

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

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>

Hibernate exception when create table

I just started creating project in Hibernate, and I have problem at the begining.
While I try create a simple table I get these errors:

And i can't find solution. Strange is i get warning about deprecation of org.hibernate.ejb.HibernatePersistence, but i can't use it. I use org.hibernate.jpa.HibernatePersistenceProvider as is shown below.
Anything strange thing is error about no table named "User". Of course is not there, I want to create it!
Additionaly I am using Intellij Idea 14 if its important.
Tere are my class and config file:
persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" version="2.1">
<persistence-unit name="NewPersistenceUnit">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<properties>
<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/gmlDatabase"/>
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
<property name="hibernate.connection.username" value="lukasz"/>
<property name="hibernate.connection.password" value="p4ssw0rd"/>
<property name="hibernate.archive.autodetection" value="class"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hbm2ddl.auto" value="create-drop"/>
</properties>
</persistence-unit>
</persistence>
User.java:
#Entity
public class User {
#Id
#GeneratedValue
private Long id;
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
and Main.java:
public class Main {
public static void main(String[] args) {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("NewPersistenceUnit");
EntityManager entityManager = entityManagerFactory.createEntityManager();
User user = new User();
user.setName("Janek");
entityManager.getTransaction().begin();
entityManager.persist(user);
entityManager.getTransaction().commit();
entityManager.close();
entityManagerFactory.close();
}
}

I don't believe using create-drop will update an in-place schema to re-add the table that you dropped. Try:
<property name="hbm2ddl.auto" value="update"/>
This is create a schema if one doesn't exist, and attempt to modify an existing one to match the mapping you have defined.
Also see this,
Hibernate hbm2ddl.auto possible values and what they do?

First of all check permissions of user (in this case yours is "lukasz"), be sure that you have create database permission. If user doesn't have permission , you can use this command ;
GRANT ALL PRIVILEGES ON * . * TO 'lukasz'#'localhost';

A Couple things stand out to me.
It looks like the exception is coming from an attempt to insert into the user table. From the stack trace it looks like it's being thrown when you call persist. You also say you're trying to create the user table. Unless I've been misusing EM.persist() all these years, it won't create a table, it will just insert/update that record in the table. You need to actually go into your SQL and create the user table. Something like
CREATE TABLE gmlDatabase.User (
id NUMBER,
name VARCHAR(255)
);
Specific syntax may vary depending on what database software you are using
If the table isn't going to have the same name as the hibernate class name you'll need to add a name field to the #Table annotation.
#Table(name="user_table", schema="gmlDatabase")
public class Table {
...
I don't think you'll actually need that in this case, though. It looks like you want the class and table to both have the name "User".
Finally, try listing the specific class under the persistent-unit tag in your persistence.xml Something like
<persistence-unit name="NewPersistenceUnit">
...
<class>com.pkg.otherpkg.User</class>
</persistence-unit>

Add a #Table(schema="gmlDatabase") to the Entity
UPDATE
I guess Hibernate creates an AUTO_INCREMENT for the primary key in the User table? If so you've to set the GenerationType to IDENTITY.
#GeneratedValue(strategy=GenerationType.IDENTITY)

Ok, I partly solved problem.
Partly, because I have to manually create table and correct columns.
This is log, but it isn't so hopefully.

I rolling back every changes in my code, and now it look like in first post.
Now question is why hibernate doesn't create this table?

Error while connecting to DB with hibernate

I am trying to learn Hibernate. And this is my first program, however I cannot figure the problem out while compiling. I use Postgresql, which is already opened to the connection.
This is the model:
package org.javabrains.koushik.dto;
import javax.persistence.Entity;
import javax.persistence.Id;
#Entity
public class UserDetails {
#Id
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;
}
}
Test class:
package org.koushik.hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.javabrains.koushik.dto.UserDetails;
public class HibernateTest {
/**
* #param args
*/
public static void main(String[] args) {
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("First User");
#SuppressWarnings("deprecation")
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
session.save(user);
session.getTransaction().commit();
}
}
And the hibernate.cfg.xml:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

I think the problem is hilarious, sorry for that but it is just starting point for me.

In your configuration
<property name="connection.url">jdbc:postgresql://host:5432/hibernatedb</property>
I do not think this url is correct. At least you can try jdbc:postgresql://localhost:5432/hibernatedb or some other end point.
Because the error log suggests that the problem is "Caused by: java.net.UnknownHostException: host"

At least you can try jdbc:postgresql://localhost:5432/hibernatedb or some other end point.
Like:
jdbc:postgresql://localhost:5433/hibernatedb
See your
/etc/postgresql/9.x/main/postgresql.conf
(in my case by default: port = 5433).
