title: NoClassDefFoundError in simple .jar file
body: <p>I'm trying to create a simple .jar file out of my project. The project is made of two .class files - the main class which uses the secondary class to generate a GUI. The main class is the actual "main" class that runs while the second class is just a class file with it's methods and it's also an <em>extension</em> of JFrame and imports javax.swing and java.awt.event.*.</p>
  
  <p>I use Jar to bundle it all up. I add a manifest file (with a new line character) which points to the primary file with the main method. The Jar file thus has two .class files and a folder with the manifest.txt in it. When I use javaw.exe to run it, nothing happens at all. So I try to run it in the command line and I get a NoClassDefFroundError about the secondary class.</p>
  
  <p>I noticed I get the same kind of error when I try to compile and run the second class in JCreator - no wonder, it doesn't have a main method, it's just a class file. When I run the main file from JCreator, everything works fine.</p>
  
  <p>Any ideas?</p>
