Java JDBC classes
Hello Community!
I am working on a tutorial (Adobe Experience Manager Help | Persisting Adobe Experience Manager data in a relational database ) and have a question.
At following section, seemed like I need add some application logic to the CQJDBCProject.
I still new to the AEM and I just want to know how to make a form and store/retrieve the data to/from MySQL.
So, I don't mind using default class. As the note mentioned, there is a default class but when I open the page, it jumped to unsupported versions of AEM.

I know I'm using AEM 6.3 and this is tutorial for 5.5 / 5.6.
Does anybody know newer version of this tutorial or have the jar file I need to carry on this tutorial?
Thanks!
Ryu
