I think this was brought up on the list before, but that was just a 
mistake in the README.txt that made it's way into the release 
distribution (wasn't updated from the alpha/beta/RC phases).  OpenSAML 
2.1.0 is a fully supported released version of the software.

That's very strange.  This might be caused if you are trying to used the 
opensaml-2.0.0.jar with the newer versions of openws and xmltooling from 
OpenSAML 2.1.0.  I would suggest re-downloading the latest tarball or 
zip and making sure you have a consistent set of all 3 libraries in the 
OpenSAML stack.  That would be:

opensaml-2.1.0.jar
openws-1.1.0.jar
xmltooling-1.0.1.jar

And make sure to remove any other versions of those 3 jars from your 
classpath.
