Yes, you have not registered an XMLSignatureFactory provider
implementation.
The easiest workaround is to just instantiate and specify the service
provider implementation (bundled with Apache XMLSec) as a parameter as
follows:
XMLSignatureFactory factory = XMLSignatureFactory.getInstance("DOM", new
org.jcp.xml.dsig.internal.dom.XMLDSigRI());
Alternatively, you can register the provider in the java.security file,
or use the java.security.Provider API. See
http://java.sun.com/javase/6/docs/technotes/guides/security/crypto/CryptoSpec.html#ProviderInstalling
"Registering a Provider" for more details.

I'm trying to validate a signature using xmlsec 1.4.1 and am getting the

The code is:
NodeList nl = doc.getElementsByTagNameNS(XMLSignature.XMLNS,
"Signature");
if (nl.getLength() == 0) {
throw new Exception("Cannot find Signature element");
}
DOMValidateContext valContext = new DOMValidateContext(pk,
nl.item(0));
XMLSignatureFactory factory =
XMLSignatureFactory.getInstance("DOM");
...
Any ideas?
