Solution
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
Problem
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 at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at org.jboss.logging.Logger.getMessageLogger(Logger.java:2248) at org.jboss.logging.Logger.getMessageLogger(Logger.java:2214) at org.hibernate.cfg.Configuration.<clinit>(Configuration.java:184) at be.comp.permanenties.HibernateUtil.<clinit>(HibernateUtil.java:15) at be.comp.dao.balie.ZitdagenDAOMySQL.findByMaCode(ZitdagenDAOMySQL.java:31) at be.comp.permanenties.Main.main(Main.java:19) Caused by: java.lang.ClassNotFoundException: javax.transaction.SystemException at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 8 more ``` 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"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <!-- Development --> <property name="hibernate.connection.url">jdbc:mysql://127.0.0.1:3306/balie?autoReconnect=true&useUnicode=true&characterEncoding=iso-8859-1</property> <property name="hibernate.connection.username">username</property> <property name="hibernate.connection.password">password</property> <property name="hibernate.default_catalog">db</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property> <!-- JDBC connection pool (use the built-in) --> <property name="hibernate.connection.pool_size">1</property> <!-- Enable Hibernate's automatic session context management --> <property name="hibernate.current_session_context_class">thread</property> <!-- <property name="hibernate.current_session_context_class">org.hibernate.context.internal.ThreadLocalSessionContext</property>--> <!-- Disable the second-level cache --> <property name="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</property> <!-- Echo all executed SQL to stdout --> <property name="hibernate.show_sql">true</property> <!-- Drop and re-create the database schema on startup --> <property name="hibernate.hbm2ddl.auto">update</property> <!-- List of XML mapping files --> <mapping resource="be/comp/model/balie/Zitdagen.hbm.xml"/> </session-factory> ``` I am unable to figure out where the error might be. All help is welcome. Thanks.
