  </code></pre>
  <p>Have no idea why im getting that exception</p>
  <p><strong>EDIT1</strong>
  here is principal.Cliente</p>
  <pre><code>public class Cliente {
      private String name;
  
      public Cliente(String name) {
          this.name= name;
      }
  }
  </code></pre>
  <p><strong>EDIT 2</strong>
  removed a bunch of useless code to make it look cleaner</p>
