title: Error: Could not find or load main class in Eclipse
body: <p>I'm having trouble running a project in Eclipse 4.2. I have a Java program with one class titled Conversion.  Eclipse builds the project fine.  I'm able to run the program from the command line by navigating to /bin/ in the project's folder that's in the workspace and typing <code>java Conversion</code>.</p>
  
  <p>However, when I try to run the program from Eclipse, I am shown <code>Error: Could not find or load main class Conversion</code> in the console.</p>
  
  <p>The project name is <code>10.12.12: Project</code>.</p>
