Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError

[wappers]

I am trying to get Hibernate 3 working from Spring, I currently get this exception under Tomcat 5.5:

root cause 

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/springapp-servlet.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError

This is particularly useless as is does not give me the missing class name. Any ideas what it could be/why it does not give me a class name? Should I be supplying a class name somewhere but I am not?

	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="mappingLocations">
			<value>/WEB-INF/test.hbm.xml</value>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
				</prop>
			</props>
		</property>
	</bean>

Do you have spring.jar and hibernate.jar in your classpath?

[wappers]

I have hibernate3.jar and spring.jar, plus spring-hibernate.jar on my class path. As I was setting up this I have had other NoClassDefFoundError exceptions, but they have always given me the class names, e.g. for dom4j. Which enables me to add the jar, but now I do not have the name of the missing class.

[wappers]

I imagine this error would be an error in the class loader, not supplying the classname in the exception.

The jars are in tomcat/common/lib/

Found a way past his, I moved all of the other jars from the application lib directory to common/lib, not sure which one it was though.
