java.lang.NoClassDefFoundError: Could not initialize class org.com.hibernate.HibernateUtil

Question

This is my hibernate util code

public class HibernateUtil {

private static final SessionFactory sessionFactory = buildSessionFactory();

private static SessionFactory buildSessionFactory() {
    try {
        // Create the SessionFactory from hibernate.cfg.xml
        return new AnnotationConfiguration().configure().buildSessionFactory();
    } catch (Throwable ex) {
        System.err.println("Initial SessionFactory creation failed." + ex);
        throw new ExceptionInInitializerError(ex);
    }
}

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}
}

this is my 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">

<hibernate-configuration>

<session-factory>

    <!-- Database connection settings -->
    <property name="connection.driver_class">
        oracle.jdbc.OracleDriver
    </property>
    <property name="connection.url">
        jdbc:oracle:thin:@127.0.0.1:ABC
    </property>
    <property name="connection.username">abc</property>
    <property name="connection.password">***</property>

    <!-- JDBC connection pool (use the built-in) -->
    <property name="connection.pool_size">3</property>

    <!-- SQL dialect -->
    <property name="dialect">
        org.hibernate.dialect.Oracle10gDialect
    </property>

    <!-- Enable Hibernate's automatic session context management -->
    <property name="current_session_context_class">thread</property>

    <!-- Disable the second-level cache -->
    <property name="cache.provider_class">
        org.hibernate.cache.NoCacheProvider
    </property>

    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">true</property>

    <!-- Drop and re-create the database schema on startup -->
    <property name="hbm2ddl.auto">update</property>

    <mapping class="org.com.tables.User_Details" />
</session-factory>

</hibernate-configuration>

and this is the error

Could not initialize class org.com.hibernate.HibernateUtil... What's the package name of your util class ? — Vrushank

I think hibernet lib is not added properly. Please check that first. — Ketan Bhavsar

What kind of package name is "org.com.hibernate"?! In any case, if that's your class, it, or one of its dependencies, isn't being deployed. I'm surprised there's no "caused by" in the stack trace--are you sure there isn't? — Dave Newton

You can download jars related to hibernate at

http://sourceforge.net/projects/hibernate/files/hibernate3

unzip it and check whether the following files are added to your lib folder

Anttr-2.7.6.jar
asm.jar
asm-attrs.jar
cglib-2.1.3.jar
commons-collections-2.1.1.jar
commons-logging-1.0.4.jar
ehcash.jar
dom4j-1.6.1.jar
hibernate3.jar    <--Check this version of your jar
jta.jar
log4j-1.2.3.jar

To run hibernate related programming and among all the jars hibernate3.jar is the main file..

Along with the hibernate jars you must include one more jar file related to the type of database(mysql,oracle,etc..) you use..

Try using proper versions of jar before you execute your program...some versions of jars are not supported to run...and the latest one is recommended...

If someone is facing the same problem who are using Glassfish server you have to do the following,

Go your Glassfish installation path and add your database's jdbc driver under the path glassfish/domains/domain1/lib/
Restart your Glassfish server.

You haven't provided the package name in your HibernateUtil class. If no package is defined the class will belong to default package and you cannot get the HibernateUtil class from org.com.hibernate.HibernateUtil
