I explored that suggestion. The class failing to load is
org.hibernate.SessionFactory, and the class attempting to load it is
HibernateGrailsPlugin. The former class is confirmed in a jar in
WEB-INF/lib, and the latter is a .class file in WEB-INF/classes. It seems
like this should work.
The details:
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'pluginManager' defined in ServletContext resource
[/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested
exception is
org.codehaus.groovy.grails.exceptions.NewInstanceCreationException: Could
not create a new instance of class [HibernateGrailsPlugin]!
