  <p>Using the Json Jackson parser I have populated the List with this data.</p>
  
  <pre><code>List&lt;Advertisement&gt; advertisements = mapper.readValue(url, new TypeReference&lt;List&lt;Advertisement&gt;&gt;(){});
  </code></pre>
  
  <p>Now I want to populate the jTable, I have used the NetBeans GUI builder to create frame and the table. The table name is advertisementList_JT. So far what I have tried is this snippet of code found in a simillar question here on the site.</p>
  
  <pre><code>DefaultTableModel model = new DefaultTableModel();
          for (Advertisement adv : advertisements) {
              Object[] o = new Object[3];
              o[0] = adv.getName();
              o[1] = adv.getPublication_starts();
              o[2] = adv.getPublication_ends();
              model.addRow(o);
          }
          advertisementList_JT.setModel(model);
  </code></pre>
  
  <p>With this snippet the table when I start the application just goes gray and nothing happens, looked thru the debugger and no errors either.</p>
