[dna-users] Building DNA Question

[Ben Abernathy]

Hi,

I'm not sure if this should go to the users list or the dev list, but
I'm having some trouble building DNA. I checked out trunk from svn and
am using maven version 2.0.9 and jdk 1.5. I'm wondering if I'm having
a JDK 1.5/1.6 version issue because I get the stack trace inserted at
the end of this email. Is there a wiki page or something describing
how to successfully build DNA?

Thanks in advance,

Ben
