title: decompile and recompile tomcat-coyote.jar
body: <p>I need to debugg tomcat-coyote, in order to modify Cookies.class and CookieSupport.class.
  I've used Java Decompiler for extracte and modify the source code.</p>
  
  <p>After this, I recompile my folder (tomcat-coyote) with this commande: </p>
  
  <blockquote>
    <p>jar cf tomcat-coyote.jar tomcat-coyote</p>
  </blockquote>
  
  <p>But when i start my localhost with my new tomcat-coyote in the lib folder, the server doesn't run, and I got this error:</p>
  
  <blockquote>
    <p>Server Tomcat 7 failed to start.</p>
  </blockquote>
  
  <p>is it-some have already faced the problem?</p>
  
  <p>thanks in advance</p>
