body: <p>When I executing the following code: </p>
  
  <pre><code>public static void main(String[] args) {
      try {
          FirefoxDriver driver = new FirefoxDriver();
          driver.get("http:www.yahoo.com");
      } catch (NoClassDefFoundError ex) {
          System.out.println("error: " + ex.getStackTrace());
      }
  }
  </code></pre>
  
  <p>I'm facing the following error: </p>
  
  <blockquote>
    <p>error:[Ljava.lang.StackTraceElement;@80f4cb</p>
    
    <p>Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/base/Function</p>
