Hi Seth,
With XACML 2.0, I was using the 1.0 namespace in the
policy and request xml files.
I no longer get the NullPointer exception for
condition.
The revised (for 2.0) policy and request files are
attached.
I get the below exception:
================================================================================
ExpressionHandler.getFunction root.getAttributes() :
FunctionId="urn:oasis:names:tc:xacml:1.0:function:anyURI-is-in"
ExpressionHandler.getFunction
root.getAttributes().getNamedItem('FunctionId') :
org.apache.crimson.tree.AttributeNode@1e152c5
java.lang.IllegalArgumentException: illegal parameter
