Spring & hibernate configuration (using maven): java.lang.ClassNotFoundException: org.hibernate.cfg.Configuration

Question

I am trying to include spring and hibernate in an application running on a Weblogic 10.3 server. When I run the application in the server, while accessing an TestServlet to check my configuration I get the following exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mySessionFactory' defined in class path resource [spring-config/HorizonModelPeopleConnectionsSpringContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org.hibernate.cfg.Configuration

I have checked my application and the hibernate jar file is included and it contains the class it says its missing: org.hibernate.cfg.Configuration.

The application is built with maven. These are the dependencies of the JAR file using spring and hibernate:

    <!-- Frameworks -->
    <!-- Hibernate framework -->
<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate</artifactId>
  <version>3.2.7.ga</version>
</dependency>
<!-- Hibernate uses slf4j for logging, for our purposes here use the simple backend -->
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-log4j12</artifactId>
      <version>1.5.2</version>
</dependency>
<!-- Hibernate gives you a choice of bytecode providers between cglib and javassist -->
<dependency>
  <groupId>javassist</groupId>
  <artifactId>javassist</artifactId>
      <version>3.4.GA</version>
</dependency>
    <!-- Spring framework -->
<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-orm</artifactId>
  <version>2.5.6</version>
</dependency>

At first I thought it could be an issue with the versions in the spring and hibernate libraries, so I have tried with different ones, but still I couldn't find anywhere where it says which library versions are compatible,. just got that Spring 2.5.x needs hibernate >=3.1

And this is my Spring config file:

</beans>

            spring-orm-2.5.6.jar
            spring-tx-2.5.6.jar

Is there any dependency or configuration I am missing?

If I use hibernate without spring using (with the same libraries) I don't get the ClassDefNotFoundException:

import java.net.URL;

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


public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            URL hibernateConfigURL = HibernateUtil.class.getClassLoader().getResource("hibernate-config/hibernate.cfg.xml");
            return new Configuration().configure(hibernateConfigURL).buildSessionFactory();
        }
        catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

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

That makes me think that is not a problem with the hibernate library not being properly picked. The Spring libraries seem to be picked properly as it starts to build the beans from the ApplicationContent. Could it be an issue of these two libraries not seeing each other?

Have you checked to make sure that there are no hibernate or Spring JARs located elsewhere on the webapp's classpath, perhaps as a part of a shared/server-wide library? — matt b

I first thought that could be the reason as I was initially deploying in a server with loads of libraries, but later I deployed into another server (integrated in oracle's JDeveloper IDE) which I believe (but not 100% sure) it doesn't contain any spring or hibernate and still got the same error. Do you know any application or utility to check if a jar or class is already in the same class loader in order to be 100% sure? — Marcos Carceles

My guess is that your application is not using the Spring JARs inside the webapp but the one provided by WebLogic and those can't "see" the Hibernate JAR inside the war.

To tell Weblogic to look into the war file, provide a WEB-INF/weblogic.xml with prefer-web-inf-classes set to true (this is required for Hibernate anyway because of the ANTLR version bundled in WLS):

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90" xmlns:j2ee="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">
  <context-root>/myApp</context-root>
  <container-descriptor>
    <prefer-web-inf-classes>true</prefer-web-inf-classes>
  </container-descriptor>
</weblogic-web-app>

again +1, and again my point is why isn't this the default setting :) You see - too many classpath problems arise from this, and you almost always have to use this (or similar) settings. Application servers are released more rarely compared to to small upgrades in bundled libraries.

Pascal Thivent Over a year ago

@Bozho I get your point but still, a parent first classloader strategy is what I would expect (using another strategy = know what you're doing).

Bozho Over a year ago

yes, you would expect it. And will know which setting to change in 99% of the cases. Others will not expect it :) That said - in what case actually it makes sense to have the bundled library loaded, instead of the one in the application?

Pascal Thivent Over a year ago

@Bozho servlet.jar, hibernate.jar in JBoss, etc :) It's actually a way to protect people from themselves. My point is that if you don't want to use the provided JAX-WS implementation, or the Spring supported version, etc then I think it makes sense to have to explicitly configure your application for this. It's a way to say I know what I'm doing, I'm responsible of my mistakes.

Bozho Over a year ago

here's the difference I think - servlet.jar and hibernate.jar are of different nature. servlet.jar is something that is "provided", because the server implements a certain version of the servlet api. And even if you put servlet-3.0.jar, it won't work. But hibernate is another thing - you don't (or shouldn't) rely on the container for that.

You have missed the hibernate-core dependency...example in the docs.

http://docs.jboss.org/hibernate/stable/core/reference/en/html/tutorial.html#tutorial-firstapp-mvn

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
    </dependency>

Hi, my first approach was to use org.hibernate:hibernate-core:3.3.2-GA instead of hibernate-3.2.7.ga.jar. Both already include the missing class, shouldn't it be anough with any of either?

i had compile 'org.hibernate:hibernate-core:4.1.9'

i replaced it with compile 'org.hibernate:hibernate-core:3.3.2.GA'

this is gradle syntax, converting to maven isnt difficult

In addition to your answer @Rafeeq, this did the trick should incase you are using Maven dependency on pom.xml

<dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-core</artifactId>
            <version>3.3.2.GA</version>
        </dependency>
