  Jython 2.5.4rc1<br>
  Django 1.4.5<br>
  Django_jython-1.3.0  </p>
  
  <p>I am trying to follow the tutorial @ <a href="https://docs.djangoproject.com/en/1.4/intro/tutorial01/" rel="nofollow">https://docs.djangoproject.com/en/1.4/intro/tutorial01/</a></p>
  
  <pre><code>django-admin.py startproject mysite
  </code></pre>
  
  <p>worked fine and I now have my project structure. But then</p>
  
  <pre><code>jython manage.py runserver
  </code></pre>
  
  <p>generated a gigantic traceback error. Here are just excerpts from the start, middle and end.<br>
  It begins:</p>
  
  <pre><code>Traceback (most recent call last):

  <p>This is definitely not what is to be expected. I can imagine that it is some kind of configuration problem, but I have no idea what.</p>
  
  <p>Many thanks in advance for all assistance.</p>
