You'll need to partition the data at the application level. We don't provide

lightweight version of this, but ultimately it'll be up to your application
to decide who has the rights to see which data.

I'd recommend Google Guice. Your web.xml becomes a stub, and
you can write beautiful module configurations such as:

}

There is no problem presented here with the "enhancer" complaining.

Hi Ikai,
Effectively the code you provided seems to work but not exactly as I

Before 1.2.8, I was able to send an html email with inline images
using the previous code.
Now the image is sent as an external attachment.
It's really sad we can't send nice html messages with images anymore.

Hey no problem. All is well. We can determine the class by the key

if(key.getKind().
