title: Jaybird java.lang.NoClassDefFoundError
body: <p>Probably I'm asking a common question but I really don't get what I'm doing wrong and what I could forget when I try to connect with my Firebird DB through Jaybird. I've added the <strong>Jaybird.jar</strong> to my Java build path but still getting an error  <strong>java.lang.NoClassDefFoundError</strong>.</p>
  
  <p>Here is my simple code:</p>
  
  <pre><code>public class DBHelper {
  
  
      public void tryConnect() {
         try {
             Class.forName("org.firebirdsql.jdbc.FBDriver");
         } catch (ClassNotFoundException cnfe) {
             System.out.println(cnfe.toString());
             System.out.println("org.firebirdsql.jdbc.FBDriver not found");
         }
     }
  }
  </code></pre>
