    <p>I have a list of data which I got from my Json file using Json Jackson, how can I populate jTable from this list?</p> <pre><code>[{"id":1,"name":"Bambola","description":"Opis...","contact_number":"022\/349-499","email":"","address":"Svetosavksa 23","geo_latitude":"44.96868000000000","geo_longitude":"20.28140000000000","created_at":"2013-06-24 14:15:08","updated_at":"2013-06-24 14:15:08","deleted_at":null,"publication_starts":"1991-05-24 01:00:00","publication_ends":"1991-05-24 01:00:00"},{"id":2,"name":"Master","description":"Opis...","contact_number":"022\/349-123","email":"","address":"Svetosavksa 24","geo_latitude":"44.96653000000000","geo_longitude":"20.28170000000000","created_at":"2013-06-24 14:15:08","updated_at":"2013-06-24 14:15:08","deleted_at":null,"publication_starts":"0000-00-00 00:00:00","publication_ends":"0000-00-00 00:00:00"},{"id":3,"name":"Tritel","description":"Opis...","contact_number":"022\/321-499","email":"","address":"Svetosavksa 25","geo_latitude":"44.96654000000000","geo_longitude":"20.28170000000000","created_at":"2013-06-24 14:15:08","updated_at":"2013-06-24 14:15:08","deleted_at":null,"publication_starts":"0000-00-00 00:00:00","publication_ends":"0000-00-00 00:00:00"}] </code></pre> <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>

    2. COThe basic code you posted looks fine, but we don't know the context of how the code is invoked. If the frame is grey then I would suggest that you don't actually add the table to the frame. Maybe you have instance and local variables. Add some debug statements to you code see if you code is even being executed.

    3. CO@mKorbel: Why don't you like the DefaultTableModel? Most tables don't need a custom table model.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
