title: How to convert a (.JAR) file to UML?
body: <p>Please I have a .JAR file, i would like simply to convert this file to a UML. 
  I have (NetBeans 6.9.1) and (Eclipse IDE for Java Developers) both installed on my machine. </p>
  
  <p>Any suggestions are greatly appreciated! </p>
  
  <p>Thanks in advance!</p>
  
  <p>P.S: Using some search engines, i found (JAR2UML) plug-in for eclipse but sadly i failed in installing it.</p>
