Hi Charlie / Brooks,
Sorry for the delay in response.
Brooks, I did end up splitting the big chunk into simpler statements like
this *SignatureElement =
docElement.getElementsByTagNameNS(SignatureSpecNS,"Signature").item(0);
*
Charlie, Good explanation and thats what I thought about my init method,
that its calling with right parameters and it should be fine. Anyway, I read
somewhere that easy way to resolve init issue is by doing some array
creation etc. See my sample code below because I use that and now my error
is gone. Or Perhaps, I needed to instantiate* ** Init = CreateObject("Java",
"org.apache.xml.security.Init"); *before calling another class which was
giving the error. Like you said, sometimes it has to do with missing class.*
*Here is the new code which is working fine now without errors unless I am
missing something obvious which you can point me to. Let me know if you see
something weird in this code. Charlie, if you wanna say something about that
array code below then thats fine. I would love to know your take on it. :-)
<cfscript>
xmlResponse= tokenXML;
docElement= XmlParse(variables.xmlResponse).getDocumentElement();
SignatureConstants=CreateObject("Java",
"org.apache.xml.security.utils.Constants");
SignatureSpecNS=SignatureConstants.SignatureSpecNS;
xmlSignatureClass =
CreateObject("Java","org.apache.xml.security.signature.XMLSignature");
*SignatureElement =
docElement.getElementsByTagNameNS(SignatureSpecNS,"Signature").item(0);
Init = CreateObject("Java", "org.apache.xml.security.Init");
emptyArray = ArrayNew(1);
initMethod=Init.GetClass().GetMethod("init",emptyArray);
initMethod.invoke(Init,emptyArray);
xmlSignature = xmlSignatureClass.init(SignatureElement,"");*
keyInfo=xmlSignature.getKeyInfo();
X509CertificateResolverCN =
"org.apache.xml.security.keys.keyresolver.implementations.X509CertificateResolver";
keyResolver=CreateObject("Java",X509CertificateResolverCN).init();
keyInfo.registerInternalKeyResolver(keyResolver);
x509cert = keyInfo.getX509Certificate();
isValid = xmlSignature.checkSignatureValue(x509cert);
</cfscript>
Thanks,
