I am using CF 2023 to create a POC SAML SSO to get to an SP. I am using xmlsec-2.3.5.jar and have jdk-17.0.13. I am getting this error when i do this. Any help is appreciated.

digestMethod = signatureFactory.newDigestMethod("<http://www.w3.org/2001/04/xmlenc##sha256>", JavaCast("null", "java.lang.Object"));
            writeOutput("Created DigestMethod (SHA-256)<br>");
            // Create Transforms
            transforms = createObject("java", "java.util.ArrayList").init();
			writeOutput("Initialized transforms<br>");
           // Enveloped Signature Transform
            transforms.add(signatureFactory.newTransform("<http://www.w3.org/2000/09/xmldsig##enveloped-signature>", JavaCast("null", "java.lang.Object")));
            writeOutput("Added Enveloped Signature Transform<br>");

I am getting the error on: transforms.add(signatureFactory.newTransform("http://www.w3.org/2000/09/xmldsig##enveloped-signature", JavaCast("null", "java.lang.Object"))); Error: The newTransform method was not found. Type: Object Detail: Either there are no methods with the specified method name and argument types or the newTransform method is overloaded with argument types that ColdFusion cannot decipher reliably. ColdFusion found 2 methods that match the provided arguments. If this is a Java object and you verified that the method exists, use the javacast function to reduce ambiguity. Java stack trace:

CF 2023 has built-in support for SAML. Right? Have you tried that? Full discloser - I have not tried it and am not running CF 2023. But for a simple POC I would start with that first. Integrate SAML and LDAP support with ColdFusion Administrator
