Sorry about the double post guys.  I had 
emailed from a different account and wasn't sure if it would show up or not, so 
I resent using the account from which I had registered to the list.

  Subject: java.lang.NullPointerException 
  when initializing AbstractSAXSource
  
  I've got a class that extends 
  AbstractSAXSource.  My class's constructor is called with the 
  parameters:
   
  Environment 
  ComponentManager
  Logger
  and others...
   
  The first time that this class is instantiated 
  once the j2ee (Jboss) system has been started, it runs fine.  No 
  problem.
   
  However, subsequent calls to instantiate the 
  AbstractSAXSource result in a java.lang.NullPointerException.  The 
  frustrating thing is that that is all the information.  It does not tell 
  me what is null.  I have checked each of the three parameters  
  before calling the super-constructor (super == AbstractSAXSource), and all 
  three parameters are not null.
   
  Is there any way for me to get more information 
  out of this?  Wow, it's really frustrating.  Has anyone here had 
  problems like this?
   
  Unfortunately, I am an avalon/cocoon newbie, 
  and  just inherited this application with little documentation.  I 
  would really appreciate any pointers you all could give me on how to resolve 
  this problem.
   
  thanks,
  Collin
