Did you download version 0.3, or something else? And just in case, what platform are you running on?
I followed the link on "Running the example...", but taking a closer look I see it is pointing to the 0.2 URL
I replaced the 0.2's with 0.3's and have download that zip file. I'll give that a try.
I'm running this in Vista.
Oh, sorry 'bout that. The link has been fixed in the 0.3 document.
I also just downloaded the examples from http://www.jboss.org/file-access/default/members/dna/downloads/0.3/jboss-dna-0.3-gettingstarted-examples.zip, unzipped them, and ran "mvn install" and the projects built and all unit tests passed. I was even able to run the example applications.
Let us know what you find out and if you have any more problems.
After downloading the 0.3 version, everything is working now.
