Looks like some jars are missing, ie the spring-hibernate.jar (from the SpringDAO/ORM lib) and the spring-mock from the Spring Testing lib.
Having said that, I created a new user lib for these, added them (pointed to ME_HOME/com…springframework/data/1.2/lib).  This made most of my errors go away.  the one that remains is in the spring applicationContext.xml file.  It claims it still can’t find:
Severity    Description    Resource    In Folder    Location    Creation Time
2    Class ‘org.springframework.orm.hibernate3.HibernateTransactionManager’ not found    applicationContext.xml    AssetmgmtPersistence/src/conf    line 75    August 30, 2005 10:26:02 AM
2    Class ‘org.springframework.orm.hibernate3.LocalSessionFactoryBean’ not found    applicationContext.xml    AssetmgmtPersistence/src/conf    line 49    August 30, 2005 10:26:02 AM
These two classes are part of the spring-hibernate.jar (which is visible on my classpath.  from a java source file I can navigate the classes in this package via the import statement).
Here is the one of the sections in my applicationContext.xml:
    <bean id=”transactionManager”
        class=”org.springframework.orm.hibernate3.HibernateTransactionManager”>
        <property name=”sessionFactory”>
            <ref local=”sessionFactory” />
        </property>
    </bean>
As part of my upgrade, I removed the M3 version of ME, then installed fresh on ME4.
If I figure anything out, I’ll post again.

EDIT: Added applicationContext.xml fragment.
