OpenSAML user discussion

[Paul Mazzuca <>]

I have been trying to sign a SAMLAssertion however after compiling, when I 
run 
the test program I get the exception below.  I thought that perhaps I did not 
have the JCE package but the jar files are in the java 1.4.2 directory. Has 
anyone else come across this exception? Any ideas?

org.apache.xml.security.signature.XMLSignatureException: empty
