Re: [J2] Evaluation of Spring Framework

[Scott T. Weaver]

It's fixed now.  I forgot to set PreferencesProvider's init-method in 
the jetspeed-spring.xml.  The start() method simply calls 
PreferencesImpl.class, which causes the ClassLoader to pre-load the class.

Great job Scott and David!
As we are using Spring within our own portlets you can guess I'm +1 on 
using Spring!

But, I'm having problems running J2 again after initial deployment 
using Spring. If I stop Tomcat and start again I'm presented with the 
following stack trace (in jetspeed.log):
