title: Cannot resolve dependencies with maven
body: <p>I can't seem to do anything with maven because it can't download its dependencies. When I try to run a sample application from <a href="http://openejb.apache.org/ejb3-tutorial.html" rel="nofollow">http://openejb.apache.org/ejb3-tutorial.html</a> it gives me some errors:</p>

  <p>Why can't I download the repositories?</p>
  
  <p>UPDATE: never mind. My boss told me I can't do it because of proxy setting of the company. Anyway, I just want to study ejb the fastest way without using maven if possible?</p>
