I am trying to get Hibernate 4.3 to work with my MySQL database. I am already able to use the Hibernate Code Generation tool in Eclipse and I am also able to connect to the database using the Hibernate Configurations tool.
However when I try to run code in my Main class that queries the database I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: javax/transaction/SystemException

The code in my HibernateUtil.java file is:
import org.apache.commons.lang3.SystemUtils;
import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
public class HibernateUtil {
private static final SessionFactory sessionFactoryBalie = new Configuration().configure("mysql_balie.cfg.xml").buildSessionFactory();
public static SessionFactory getSessionFactoryBalie() {
return sessionFactoryBalie;
}
}
The mysq_balie.cfg.xml file looks like:
<?xml version="1.0" encoding="UTF-8"?>

I am unable to figure out where the error might be. All help is welcome. Thanks.
you are missing jta.jar
with maven add this dep:
<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
</dependency>
or download from maven repository and add to your CLASSPATH
Above answer is correct for Maven application. But in normal applications you just add a jar file called jta-1.1.jar.
-->If your using 3.x version, that is available under your downloading hibernate distribution jar's folder path called lib/required/jta-1.1.jar.
-->If your using hibernate 4.x version, that is available under distribution folder path called dlist/lib/provided/jta-1.1.jar
If you are not using Maven/Gradle, the easier way is to download whole bundle instead of jar file one by one.
Go http://hibernate.org/orm/downloads/ and download the latest library, extract the jar from the required
folder.
