title: How to make Eclipse see .jar dropin
body: <p>I have put a .JAR file in my c:/eclipse/dropins folder. This should give me a new option on the context sensitive menu.</p>
  
  <p>It does not.</p>
  
  <p>I can't tell whether this .JAR is even being loaded - can someone help?</p>
  
  <p>The error log does not mention the JAR</p>
  
  <p>This is not a JAR created by me. It is a plugin "UCDetector" I have downloaded from the web.</p>
  
  <p>Does anyone have experience of using UCDetector?</p>
