Hibernate saving object

**solomon_13000** · May 2nd, 2011, 12:24 AM

Below is the code to save an object inside a MySql database:

test. java
-----------

Code:

import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name="test")
public class test implements Serializable{
	
	private static final long serialVersionUID = 1L;
	private String data;

	public String getData() {
		return data;
	}

	public void setData(String data) {
		this.data = data;
	}
}

database.java
----------------

Code:

import java.sql.SQLException;
import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.SQLQuery;
import org.hibernate.Session;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.orm.hibernate3.HibernateCallback;
import org.springframework.orm.hibernate3.HibernateTemplate;

public class database {
	public static void main(String[] args){
	   ApplicationContext ctx = new ClassPathXmlApplicationContext("database.xml");
       HibernateTemplate hibernate = (HibernateTemplate)ctx.getBean("hibernateTemplate");
       
       System.out.println(hibernate.executeFind(new HibernateCallback() {
    	   @Override
    	   public Object doInHibernate(Session session) throws HibernateException, SQLException {
    		   test a = new test();
    		   a.setData("john");
    		   session.save(a);
    		   SQLQuery query = session.createSQLQuery("select * from test");
    		   return query.list();
    	   }
		}).size());
   }
}

However, I am getting the following unpleasant message:

Please [ code][/code ] tags

that way your code/stacktrace/xml remains readable.

Have you registered your entity with the sessionfactory, judging from the stacktrace you haven't.

**solomon_13000** · May 2nd, 2011, 06:33 AM

Is this what you meant:

Code:

<property name="annotatedClasses">
<list>
    <value>org.test.entity.test</value>
</list>
</property>

Regards.

**Marten Deinum** · May 2nd, 2011, 07:37 AM

Please use [ code][/code ] tags !!!

!!!

Yes... Make sure that the package etc. are correct.

I did try that. However the following information was displayed:

Code:

Caused by: org.springframework.beans.factory.BeanCreationException:

I recall this wonderful case, was cumbersome to detect the cause

I did include libraries such as asm.jar, asm.attrs-jar and cglib-2.1_3.jar in my project.

The problem is about the asm versions, which has some conflicts with other dependency, I could say with Spring (not 100% sure), the error is not very clear like you see, in such days I was working with Core 3.0.2

Which Spring Core version you are using?

My solution was downloading from the Spring Repository many asm versions until to get one that work fine

Try it

HTH

**solomon_13000** · May 3rd, 2011, 11:10 AM

I'm using spring-framework-2.5.6.SEC02.

**solomon_13000** · May 3rd, 2011, 11:25 AM

To solve the problem I replaced asm.jar with asm-1.5.1.jar. Now it works!!

**dr_pompeii** · May 3rd, 2011, 11:28 AM

Good!

, I told you, I recall clearly this problem

BTW from where you get such jar?

**solomon_13000** · May 4th, 2011, 09:33 PM

I google for the jar file. Is it ok to post the link here?.
