Apache derby plugin for eclipse <p>After installing the <a href="http://archive.apache.org/dist/db/derby/db-derby-10.3.1.4/" rel="nofollow noreferrer">JavaDB plugin</a> for eclipse version 4.3.2, I unzipped the core and ui folders and put their contents under eclipse/plugin directroy.</p> <p>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.</p> <p>I'm new with the environment, help me out!</p> <p>Ps; you should be able to see packages added to eclipse java ee kepler.</p> <p><img src="https://i.stack.imgur.com/6aAOL.png" alt="enter image description here"></p>
