<pre wrap="">Hello,I am very new to this.I am using firefox and SAML tracer to watch the transactions with the idp and sp for my java web app running on tomcat. I can see a successful assertion come back to my sp from the idp, but then when the sp is processing I see the nullPointerException below. Can you please recommend ways to troubleshoot?

That's not a Shibboleth SP (obviously), and it's a bug in the code, not a runtime troubleshooting matter unless you're the one writing the SP of course.</pre>

Looking at the line numbers in the code, I suspect that the client
code isn't checking that something is actually signed before trying
to validate the (non-existent) signature. I.e. the Assertion or
Response's getSignature() is returning null, and that null return is
being incorrectly passed into the method
SignatureValidator#validate(Signature).<br>
