Hi,

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:

    <bean id="mySessionFactory"

        <property name="sessionFactory" ref="mySessionFactory"/>
    </bean>
</beans>

Is there any dependency or configuration I am missing? If I use hibernate without spring I don't get the ClassDefNotFoundException.
