Sample code:
String responseStr = "largeB64EndodedStrhere";
Base64 decoder = new Base64();
byte[] thebytes = decoder.decode(responseStr);
logger.info(new String(thebytes));
Artifact artifact = OpenSAMLUtils.buildSAMLObject(Artifact.class);

Exception in thread "main" java.lang.NullPointerException
at no.steras.opensamlbook.OpenSAMLUtils.buildSAMLObject(OpenSAMLUtils.java:48)
at no.steras.opensamlbook.sp.ConsumerServlet.main(ConsumerServlet.java:262)

btw: I bought your book! Very well put written and helpful!

Do you get this when you run my project or is this your own code?

[scanlonjts]

Minor modification made to IDPConstants (new URL for our IDP)
Minor modifcation to SPCredentials - updated keystore / password and alias

This is main method added into ‘consumer servlet’ to just test out error that I was seeing on response coming back (from our own IDP)

oh - forgot to mention this as well -

it looks like the requestParameter name coming back has been updated in Saml2 --- looks like it is supposed to be: SAMLRequest
not SamlArt

It sound like you are trying to send the response directly to the SP from the, IDP. The whole SAMLResponse is in the URL parameter, right? This app accepts artifacts that is then exchanged for a SAML response over SOAP

I have Base64 encoded SAML Response, how can i extract attributes in this approach?
Recently i had gone through your book OpenSAML v3 . Unfortunately I did not find anywhere how to extract attributes if Protocol binding is HTTP POST. can anyone direct me?
