OpenSAML user discussion

Hi, I'm new to OpenSAML.  Is the following transform algorithm supoorted?

 <ds:Reference URI="">
 <ds:Transforms>
  <ds:Transform 
Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"; /> 
  <ds:Transform Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315"; 
/> 
  </ds:Transforms>
  <ds:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"; /> 
  <ds:DigestValue>t95ULiFsNt1EcC7CgeWeV3C/TBM=</ds:DigestValue> 
  </ds:Reference>
  </ds:SignedInfo>

I've been getting "org.opensaml.InvalidCryptoException: 
SAMLSignedObject.verify() detected an invalid signature profile" error from 
calling SAMLResponse.verify(Certificate).  Does that mean the transform 
algorithm is not supported?

thanks,
