OpenSAML user discussion

["Prasanna Krishna" <>]

Hi Chad -

Probably I was not clear.

I meant a similar thread where Perez found the exception
https://mail.internet2.edu/wws/arc/mace-opensaml-users/2007-06/msg00019.html

I was getting this exception but once I picked up the latest xalan & xerces 
from apache site this exception no longer occurs but when I 'step in' in 
eclipse at bootstrap() method, it drills down till a point where validation 
of XML is being done.  Surprisingly though I have put an exception block & 
printing stack trace nothing is reported (which earlier was being reported 
when using older versions of xerces/xalan).

I thought probably any of the libraries required may be missing but I 
wouldn't find NoClassFound too in the console.

When I said it doesn't do anything I meant, it skips all the statements 
after bootstrap() statement in my method and comes out of the program 
without reporting anything.

The examples I pasted in my mail is to just provide an info that xerces & 
xalan of apache endoresed folder are indeed being picked up.

My assumption is, at few places classes from apache xerces being picked up 
but at few other places classes from sun is picked up.

Hope I could provide better info.

Regards
Prasanna Krishna
