After installing the JavaDB plugin for eclipse version 4.3.2, I unzipped the core and ui folders and put their contents under eclipse/plugin directroy.
unfortunately, clicking on a project, and adding apache derby nature lead for nothing! No packages is added to the project, and no control panel is available for the apache derby! I can repeat the process 10s times and nothing happened.
I'm new with the environment, help me out!
Ps; you should be able to see packages added to eclipse java ee kepler.
