Digital Certificates - figure 2-43

In figure 2-41, the numbering of the steps is wrong, the step from Sally to Bob should be numbered step #5 (instead of step #3).

The X.509 Digital Certificate Structure - code snippet fig 2-45

CertificateFactory certFactory = CertificateFactory.getInstance("X509");
String caCert =
"[...]www.geotrust.com/resources/root_certificates/certificates/" +
"GeoTrust_Primary_CA.pem";

should read:
CertificateFactory certFactory = CertificateFactory.getInstance("X509");
String caCert =
"[...]cacerts.digicert.com/GeoTrustPCA.crt.pem";

// seems that I am not allowed to include URLs in the description
// as GeoTrust is now DigiCert.

Corda GitHub repository at https://oreil.ly/GOX5s points to https://github.com/corda/cordapp-template-java. The template example has been refactored to bind initiator and responder into one file and now exchanges signedTransaction.

The example code matching the book is available at https://github.com/masteringcorda/masteringcorda

masteringcorda.com is no longer available.

Typo: partyA.send_api_request_get should be partyA.send_api_get_request

The obligation code @ https://github.com/corda/samples-java/tree/master/Advanced/obligation-cordapp has been refactored so the url should now be:

partyA.send_api_get_request('/api/iou/issue-iou?amount=9525&currency=USD&party=''O=ParticipantC,L=Paris,C=FR''')

note use of double ' to enclose the Corda X500 Name

The obligation code now specifies a PUT rather than GET request for issue-iou.

Either change pycorda core.py file to offer a put method or obligation file

samples-java/Advanced/obligation-cordapp/clients/src/main/java/net/corda/samples/obligation/server/MainController.java

to accept a GET request instead of PUT.
