Re: How to not persist an object

(I've inherited this issue from Dan, but I'm still a beginner here, so be 
gentle)

Todd: I'll look into the "transient" keyword since I've never seen that 
before.

Sean: I have a couple of questions:

In your example, what exactly are you sending to Open-AMF?
Are we sending Foo? Or FooInfoBean?

And how do Foo and FooInfoBean relate to each other?

Thanks,

Leif
