Hi kruti,

Hope ur problem is solved, in case if its not, just add the required libraries in ur buildpath.To run hibernate pgm properly, u need to add the required libraries in the projects buildpath.

Hi Faaud,

You can resolve your problem below problem
------------------------------------------
Exception in thread "main" java.lang.NoClassDefFoundError: net.sf.cglib.core.DebuggingClassWriter$1
------------------------------------------

by doing this:

You have add cglib-2.1.3.jar file into your class file.

OR

If you are working with eclipse 3.0 or 3.1 then this jar file should be added to user library.

OR

go to PROJECT - > PROPERTIES -> JAVA BUILD PATH -> LIBRARIES -> Add External Jars ->
define the path for this jar file.

Now i think you woun't get any error.

Inserting Record
Hibernate: insert into CONTACT (FIRSTNAME, LASTNAME, EMAIL, ID) values (?, ?, ?, ?)
Could not execute JDBC batch update

Posted by panbil on Thursday, 02.28.08 @ 14:59pm | #50403

At the time of working with this example:
- table gets created in database
- but no record is inserted

The given below is the solution for the Porblem:

In your FirstExample.java, the transaction should be started explicitly and after saveing your contact details transaction should be commited explicitly.


write below lines before the doing anything with your contact class.
-----------------------------------------------
tx = session.beginTransaction();

//Create new instance of Contact and set values in it by reading them from form object
System.out.println("Creating New Contact detail.");
Contact contact = new Contact();
System.out.println("providing contact details");
contact.setId(6); // Primary key has to be unique for every record inserted!
contact.setFirstName("subnesh");
contact.setLastName("sharma");
contact.setEmail("subnesh@gmail.com");
session.save(contact);
tx.commit();
System.out.println("Contact saved into database successfully");
------------------------------------------------


or

rather then making changes in your FirstExample.java (use same code as privided in this tutorial), you can add new property to hibernate.cfg.xml file with below code:

<property name="hibernate.connection.autocommit"> true </property>
------------------------------------

Its really nice example to the things in a repid way. Understandable and more focus is on "how to do mappings".
Good work done

As some other developers suggested to do some changes in the code, i made them and then got the data in database.

Thanks again buddy :)

Posted by Subnesh on Wednesday, 02.27.08 @ 11:19am | #50277

hi i run that program. the output in the console came as shown in the tutorial. but when i cheak the database nothing is inserted in that. did any one cheaked it. please give me suggestion. because i am new to hibernate and to java

Posted by sandeep on Tuesday, 02.26.08 @ 06:35am | #50098

Thank you. It is good to start with. I started with this example, faced some problems, but finally I got through.

Posted by vishvadeep on Wednesday, 02.13.08 @ 21:08pm | #48167

Thanks for providing source code, of hibernate
its working fine...

only small modification is in hibernate.cfg.xml
we need to include
<property name=
"connection.autocommit">true</property>

Thanks
Shrinivas

Posted by shrinivas on Wednesday, 02.13.08 @ 11:15am | #48116

I think you need these statements in your hibernate.cfg.xml. so that it commits in the database

<!-- Set AutoCommit to true -->
<property name="connection.autocommit">
true
</property>

I believe there are 2 errors in this tutorial.

1) You have to create the "hibernatetutorial" database in MySQL. The command is "create database hibernatetutorial" The hibernatetutorial database is referenced in file hibernate.cfg.xml in line "<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hibernatetutorial</property>".

2) Since this tutorial was written a while ago, I'm using a different version of MySQL than the author of this tutorial, and the default behavior of MySQL may have changed since then. At first executing FirstExample.java would create tables Contact, Book, and Insurance, but no records were inserted in any of the tables. The problem is that we need to begin a transaction, then save the session, and then commit the transaction.

As posted by nidhin:

The following line need to be added right after session open in try block of FirstExample.java

org.hibernate.Transaction tx = session.beginTransaction();

Also tx.commit(); need to be added after saving session at the end of try block to get the record in to the database.

I modified the class to the following, and it works for me.


package roseindia.tutorial.hibernate;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;


/**
* @author Deepak Kumar
*
* http://www.roseindia.net
* Hibernate example to inset data into Contact table
*/
public class FirstExample {
public static void main(String[] args) {
Session session = null;
org.hibernate.Transaction tx = null;

try {
// This step will read hibernate.cfg.xml and prepare hibernate for use
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
session =sessionFactory.openSession();
tx = session.beginTransaction();

//Create new instance of Contact and set values in it by reading them from form object
System.out.println("Inserting Record");
Contact contact = new Contact();
contact.setId(6); // Primary key has to be unique for every record inserted!
contact.setFirstName("John");
contact.setLastName("Doe");
contact.setEmail("noemail@yahoo.com");
session.save(contact);
tx.commit();
System.out.println("Done");
}catch(Exception e){
System.out.println(e.getMessage());
e.printStackTrace();
if (tx != null) {
System.out.println("Rolling back transaction");
tx.rollback();
}
} finally {
try {
// Actual contact insertion will happen at this step
session.flush();
session.close();
} catch (Exception e){
e.printStackTrace();
}

}

}
}

The hibernate tutorial which you have displayed is understandable. It makes even a fresher to understand things better.

Develop a hibernate application in eclipse:

step1: Selec the new project (java project)
right click choose build path under this configure build path. A properties of ur project window open, then click libraries add the jars then choose order and export , select all then click ok.

step two: right click ur project select new then other then click hibernate.cfg.xml then type the database url and driver and username and password details.After that run the hibernate.cfg.xml file automatically created by eclipse.

step 3: create a hibernate reverse engineering xml file (same as step 2) it is for create hbf and pojo files creation automatically.(u can configure the database table in this step)

Hi all,
the only point missing on this page is that we also need mysql db installed to run this tute. The required JDBC drives are already in the lib dir.
If you are having problems in running this tute or don't want to use eclipse or mysql then the tutorial on hibnernate's website is for you. It uses hipersonic db and no IDE.

Hi All,

Just want to add something. I did this example and it work for me until now. It’s just initially I get confused with database. So people please create database hibernatetutorial. That is in mysql and if there is password there then open then mentioned that in your hibernate.hbm.xml file. After doing so it will give exactly same result as shown above.
Hope it helps

Cheers.

Hi all

It is a fine site for develpers so carry on your efforts to facilitate them.

Thanks a lot.

Oh dear is it not possible to show a first example without eclipse?

It will be fine but has nothing to do with hibernate. If you had several problems, eclipse is also a point of failure.

Posted by Madhu on Tuesday, 07.24.07 @ 21:27pm | #21856

May be you have sent some constraints in the table which restricts your program not to add these enteries in the table, check if you have set autoincrement for your primary key and adding the same key again or get the stack trace using e.printStackTrace() in the catch block to get more generic error details.

Posted by Nesaver on Thursday, 05.24.07 @ 17:30pm | #17160

Here is the solution. In FirstExample.java, Before printing "Inserting Record", we need to create the transaction as "Transaction t = session.beginTransaction();". Then, after the line "session.save(contact)", we need to add the line "t.commit();". After, that we can enjoy the output. The Record will be get inserted in the table.

Posted by Mohanaraj Jagadeesan on Wednesday, 05.23.07 @ 17:57pm | #17098

I got the output printed on the screen exactly what is there in this page. But, the record is not getting inserted in the table. Please do the needfull help.Kind Regards, Mohanaraj. J

Posted by Mohanaraj Jagadeesan on Wednesday, 05.23.07 @ 16:21pm | #17088

I too got the same problem. Now its solved.

solution :
==========

1. place your hibernate.cfg.xml file and the other xml file in your source folder in your project.

for example: if your project name is "hibernateproject" then you will find src folder in your project tree which is the source folder and is mentioned at the time of creating your new project in Eclipse.

2. for null pointer: check all .jar files in your projects classpath whether you have everything or not..

i am sure if you have done this then you dont have any problem..

bye
Murali :)

Posted by MURALI KRISHNA on Saturday, 05.19.07 @ 19:29pm | #16566

Also Added
session.connection().commit();

Now my records are inserted successfully...

And this tutorial is simply superb for the beginners too.

What might be the possible reason that. I've configured the xml files in the same way as mentioned in tutorial. But we have to give password to acces the database. So i gave password also in the xml file.

hi ....
Fantastic job out there...
really its a good tutorials

Posted by keshav on Friday, 03.9.07 @ 14:32pm | #11237

Hi Renjith,

Hibernate is driven by XML configuration files to map classes to the database and eliminate need for respective SQL so you will not find this query in a code. It handles all create-read-update-delete operatioin using simple API no SQL.

To insert your data, you need to add two lines here.
session =sessionFactory.openSession();
Transaction tx = session.beginTransaction();
.
.
.
session.save(contact);
tx.commit();

Regards,
Sachin.

Posted by sachin on Thursday, 03.8.07 @ 18:32pm | #11163

to insert data into the Database add the following code:

1) import transaction class

import org.hibernate.Transaction;
2) add the below line after
your session =sessionFactory.openSession();


Transaction tx = session.beginTransaction();

3) add the below line after
this statement session.save(contact);

tx.commit();

4) save, compile and run as java application.

good luck

Hi,
This is for the first time in my life that i am using Hibernate. I followed the above steps mentioned and then executed the program. I came to see that the program executed succesfully.
I also got a message in the "Console" of Eclipse that,

"Hibernate:insert into contact(FIRSNAME,LASTNAME,EMAIL,ID) values(?,?,?,?)"

Then i checked the database and found that the table "Contact" was created succesfully. But it was empty and the specified values haven't inserted into it.

So i tried to find out where this "insert" statement is being mentioned. But it was in vain.

Can anyone suggest the reason for that problem and where can i find this "insert" query?

Is it possible for the user to specify the query. If yes, where?

Hi ,
Those who could not insert data to the database, add the transaction support as shown below. It works for me

session =sessionFactory.openSession();
Transaction tx = session.beginTransaction();
.....................
.....................
session.save(contact);
tx.commit();
//session.close();

Posted by Dileep on Sunday, 02.11.07 @ 10:54am | #7313

to avoid the nullpointerexception you have to add the following .jar-files to the "java build path" - libraries:

* hibernate3.jar
* all from the subdirectory /lib
* mysql-connector-java-5.0.4-bin.jar (jdbc-driver)
* the JRE of course :)
