Hi Toby,
I've just realised that I probably over-wrote the app with a new

my recollection is that I tried it a few times over a couple of days

Then I added a new attribute in the JDO class, and then set value to

If you're calling print or println many times in your servlet, then it makes
sense, although the resource savings you net may not be significant.
In general, it's acceptable to use the default PrintWriter.

Pretty much, except kind() is a method for Model classes, not loaders. Like
this:

The above kind() method makes more sense (in the model instead of the

Thx for the answer, especially the correction on the transaction

Thinking out loud here:
When you use that encoded string format you can use it wherever you'd use Key.
The apparent advantage of using the encoded string format is that your dto
isn't exposing GAE's Key. With the encoded string your service layer can be
oblivious about GAE's Key, without
41 matches
