OpenSAML user discussion

[Brent Putman <>]

Your JAXP implementation is too old, apparently.

http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/parsers/DocumentBuilderFactory.html#setSchema(javax.xml.validation.Schema)


"Throws:
   UnsupportedOperationException - For backward compatibility, when 
implementations for earlier versions of JAXP is used, this exception 
will be thrown."

I don't think it's the null that's the problem, it's the use of 
setSchema period.  You need to supply a newer implementation of JAXP, 
for example Xerces.
