title: Jadclipse plugin installation issues
body: <p>I have installed the JAD plugin for eclipse.  I just downloaded the jar and put it in eclipse plugin folder and then downloaded the executable files from <a href="http://www.varaneckas.com/jad/%20and%20picked%20the%20first%20one%20as%20i%20am%20running%20winows%20-7" rel="nofollow">here</a>.</p>
  
  <p>After extracting the zip file, I see now jad.exe and double clicked it. I am not sure if any thing wrong in the installation step, but in eclipse I see jadeclispe in eclipse editor.</p>
  
  <p>When I open a class file, I see the following error</p>
