David,
I'm confused as to which operation actually works. An accessor
method (the getter) is used to fetch data from the database and the
mutator method (the setter) is used to assign data to objects which
eventually put the data into the database. At any rate, I would
recommend that you take a look at the tests in src/tests/jdo to see
how they handle BLOBs.
