OpenSAML user discussion

[Christina Cunningham <>]

Hi Håkon,

I am having problems building the opensaml jar from svn with this patch. 
I have checked out the latest copies and rebuild the java-xmltooling and 
java-openws projects too. The stacktrace is below. Am I missing something?

+ Error stacktraces are turned on.
