Subject Re: Can't get hellopjpa from examples working.
Date Tue, 12 Apr 2011 02:09:01 GMT
Hi Joep,

You're posting to the right forum. The stack indicates that there's a
problem with a connection. Have you changed anything in the sample related
to the database?

I just downloaded a fresh copy and I wasn't able to reproduce the problem
(Oracle Java 1.6.0_24 on Linux).
