Exception when creating the signature using OpenSAML lib

[Yaowen Tu]

Thanks Brent. Are you suggesting simply use:
            prepareSignatureParams(signature, signingCredential, null,
null);?

I have tried this, and after creating a signed object, when I try to
validate it, I got this exception:

org.opensaml.xml.validation.ValidationException: Apache XMLSignature does
not exist on SignatureImpl
    at
org.opensaml.security.SAMLSignatureProfileValidator.validateSignatureImpl(SAMLSignatureProfileValidator.java:70)
    at
org.opensaml.security.SAMLSignatureProfileValidator.validate(SAMLSignatureProfileValidator.java:56)
    at com.actuate.server.saml.SAML.validateSignature(SAML.java:202)

So should I try to create a "XMLSignature" manager or try to resolve this
problem?
