I keep a text file for notes when I'm developing and many times something
frustrating is very simple to fix. By default the lazyInitialization filter
is commented by default because it messes with one of the tests. If you
pull sets of child objects e.g. on a JSP most likely you will get this error
when an action is called to pull the children. Go to web.xml and you'll
find a filter to fix this there. Uncomment the filter specific to Hibernate
or JPA.
My text file notes:
