[Middlegen-user] Help with Exception

[Ntburt]

Newby Question.

I'm trying to run Middlegen to generate some EJBs, but I keep getting this
exception (which occurs when I click the "Generate" button):

[middlegen] java.lang.ClassNotFoundException:

I'm using 2.0-b1, which I understand is the most recent working version.
I'm sure this is something obvious and stupid on my part, but I'm just not
seeing the problem.


Thanks,

Nat
