OpenSAML user discussion

Håkon,
Glad that the problem turned out to be a typo and that you got it working.

I just wanted to note for the record that both approaches to registering
new object providers are correct.  It can be done programatically, as
Manuela indicated, or it can be done declaratively, as Håkon did in an
xmltooling configuration file.  However, you don't need to do both - one
or the other is sufficient.  If you are using our DefaultBootstrap
process to init the library, probably the more typical way would be to
use the declarative, config file method.

Also, it isn't necessary (and by standard Java conventions probably
isn't advisable) to put extension objects in the org.opensaml package
namespace, nor is it necessary to declare new object providers in one of
the existing object providers config files (e.g.
saml2-protocol-config.xml), which if you were using an eventual binary
distribution of OpenSAML would mean cracking open the library jar file
and editing the files and repackaging.  Instead you can and should use
config files (external to the OpenSAML jar) which contain only the
desired extension objects, validator suites and other config info, and
then load those for example by either overriding DefaultBootstap to
additionally load that config file, or by using the XMLConfigurator
load() methods directly.

Thanks,
Brent
