com.ibm.websphere.servlet.error.ServletErrorReport：java.lang.NoClassDefFoundError：org.hibernate.impl.SessionFactoryImpl

Question

I am unable to create the session factory object. When I put the log statement line by line, code is failing at HibernateUtil.createSessionFactory() method. Can you please help where am I going wrong here ? I am attaching all the relevent code which I am using.
I think the error is misleading as it suggests the error as
1. "ClassNotFoundException: org.objectweb.asm.Type" inspite the availability of asm-1.5.3.jar.
2. com.ibm.websphere.servlet.error.ServletErrorReport: java.lang.NoClassDefFoundError: org.hibernate.impl.SessionFactoryImpl
All the hibernate 3 related jar files are in classpath Below are the code

Answer 1

You need the class org.hibernate.impl.SessionFactoryImpl.class in your project. Try to import hibernate-3.0.5.jar in your classpath.

Answer 2

The issue was not with the jar files but the folder name in which all the jars were present. May be WAS7 does not consider space as part of folder name. We renamed jar folder name used by the shared library from "SPRING HIBERNATE AND ADAMS" to "SPRING_HIBERNATE_AND_ADAMS" (space replaced with underscore) and everything started working fine.
