LocalSessionFactoryBean - Could not instantiate bean class

Question

Hello,
I am facing a problem with the instantiation of the LocaSessionFactoryBean in a sample Spring 3.0.4 - Hibernate 3.2.6, WebLogic 10.3.3 and Oracle 10g. I am run an web application using JDeveloper 11.1.1.3.0 with the integrated WebLogic Server 11gR1. Trying to make the existing web application that is currently running on Oracle Web Server to run on WebLogic.
I have gone through other LocalSessionFactoryBean related postings but could not find any solutions for my problem.
Here's the server.log during web application deployment and startup -
org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'pocDaoTarget' defined in class path resource [spring-chbs.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'sessionFactory' defined in ServletContext resource [WEB-INF/xml/spring/spring-j2eeservices.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationExcepti on: Could not instantiate bean class [org.springframework.orm.hibernate3.LocalSessionFac toryBean]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError

Any help would be greatly appreciated.

Hi Raphael,
Thanks for your response.
The last part of the console log output during run –

[Application AppServerConversion deployed to Server Instance IntegratedWebLogicServer]
Target URL -- http://127.0.0.1:7101/CFMSWeb/login.jsp
Is one of the above folder - C:\Documents and Settings\tariq.ahsan\Application Data\JDeveloper\system11.1.1.3.37.56.60\o.j2ee\drs\AppServerConversion\MaWebWebApp.war (MaWebWebApp.war is a folder) part of the IntegratedWebLogicServer deployment? Do you mean the spring and possibly the hibernate jars need to be in the WEB-INF/lib under the above folder path?
Thanks
