TL DR Want some Java assist with hooking up to some truly local database ( no use of server tech ), or if you're able to make code, which will work. All it needs to do is query the DB ( MS Access, although could be transformed ), and output a JSON string. See EDIT2 for additional specificity.
EDIT: Before anybody states JDBC I looked with the lessons ( began reading through thorough ), but many from it appears to become targeted towards server tech, which i've no use of.
EDIT2: Appears most the solutions to date are needing a set up of some type that we regrettably canrrrt do ( and unsuccessful to say, and so i apologize ). However, this is exactly what is presently getting used and I'd like an answer similar for Java that will allow it to be more mix-browser compatible instead of being HTA only (link: https://launchpad.net/accessdb )
Anyway, any assistance could be greatly appreciated. I'm able to continue developing with ActiveX ( when i realize that creates the machine and I am 99% sure they'll keep using Ie, but, would really like some versatility ).
