title: theme studio for jscookmenu
body: <p>I'm trying to run <a href="http://tapestry-jsmenu.sourceforge.net/theme-builder/" rel="nofollow">theme studio for jscookmenu</a>, by double-clicking the file <code>js-cook-menu_2.30.jar</code>. But when I do that, I get the following message:</p>
  
  <p><em>"Failed to load Main-Class manifest attribute from C:\dev\tapestry-jsmenu_2.30\js-cook-menu_2.30.jar"</em></p>
  
  <p>After searching on the internet, I found that it is necessary to specify a <code>main</code> class in the file <code>manifest.mf</code> of a jar file in order to run it. I thought that if I modified <code>js-cook-menu_2.30.jar</code> and I add a <code>manifest.mf</code> specifying a class with a <code>main</code> method, I could run the program.</p>
  
  <p>I looked on the source code provided with the downloadable package, but no success.</p>
  
  <p>Could someone help me with this? </p>
