Cybersource Testing Tool # Java utility that we used before when we were debugging the TLS 1.2 issues.
It needs to be compiled with JDK 1.8 - ideally the same one that runs in production and then run like:
java -Djavax.net.debug=ssl:handshake:verbose SSLPoke api.cybersource.com 443 replace api.cybersource.com with whatever the cybersource endpoint needs to be.
If the utility responds with ‘Successfully connected’, it was able to handshake with the SSL server and establish the secure connection.
The idea / motivation # In order to run VisualVM from predefined configuration you need to point the app to the user directory. This directory takes about 20MB, but 90% of the the content is actually generated or repeated.

Part of the beauty of JSP development is the easy of trying out the change. All you have to do is edit the JSP file, save it and reload the page. Yesterday I got caught by surprise by not being able to do exactly that. I saw some strange behaviour in an EL expression used JSP tag. As it was nothing ATG specific, I decided to try it out in plain old Tomcat rather than full ATG application. So I located the instance of Tomcat 5.5 (I always have couple of Tomcats lying around) and being lazy, I decided to inject the change into out-of the box jsp-examples Web application that comes with it.
I first time discovered Ruby back in 2006 (yes, I know, I was late to the game), and immediately fell in love with it. The dynamic nature of the language, the consistency, pure esthaetics and practicality certainly changed the way how I saw software development and programming languages.
Since that time, I made several attempts to integrate Ruby into my professional life and make it part of the toolbox. It was cool to play with Ruby in my spare time, but I wanted to use it on projects whose main development language/platform was mainly Java. Use it as scripting, glue language. Use it as toolkit language to e.g. generate test data, access databases, convert files, build projects and maybe even build a piece of Web applications (admin apps for example).
