That may be, but then there is this discussion:

In any case, I've done everything I think I need to do and it still doesn't work.  I'd be happy for someone to show me what I've done wrong, but barring that I'd still have to say, in my case, it doesn't work.

The "lazy" exception was due to Hibernate creating OneToMany annotations for fields in one table that were referenced by other tables.  These references could not be serialized and caused the exceptions.  

The references were created by Hibernate during the reverse engineering process because I had specified a foreign-key in other tables that pointed back to the first table.  I removed the foreign-keys from my MySQL DB schema and the problem went away.  The only drawback I can find on my end is that I need to add code to verify I don't have abandoned rows with links to rows that don't actually exist in other tables.  Being a C programmer originally, I'm used to writing all my own checks like this, so it's not that big a deal.  At least now I can pass back the serialized objects that represent db rows.

FWIW, I'm now passed this issue and trying to get access to the DB from a Schedulable.  Like my Web Services class, injection does not seem to work there either.  Unlike my Web Services class, I can't seem to find a work around in the schedulable because I don't know how to create a transaction and the method for retrieving the UserTransaction I used in the WS class doesn't work in a schedulable.
