Netbeans MVC Swing JTable ResultSet 数据插入

Question

I'm new to Java, Swing and programming, but I need to make an application. I'm using NetBeans for development and here's my question:

If I drag and drop the JTable to my frame and select custom code for the table, I get this code:

appView.java

tblViewData = new javax.swing.JTable();

tblViewData.setModel(new javax.swing.table.DefaultTableModel(
    new Object [][] {

    },
    new String [] {
        "ID", "Reference No", "Name", "Description"
    }
));



jScrollPane1.setViewportView(tblViewData);

What I want to do is populate new Objects[][] with data that I fetch from the appController using ResultSet and the values I set in the appModel for variables ID, Ref, Name and Desc.

Here's a sample code of an insert I attempted to see if I could display a row of data:

    new Object [][] {
        { new Integer(model.getID()), model.getRef(), model.getName(), model.getDesc() }
    },

This code returns a 0 in the first column of the row.

Am I approaching this problem wrong?

Thanks for the help.

Well I have no idea what the "appController" or "appModel" are. Maybe these are IDE dependent classes? Instead of using the IDE to generate your SQL code I suggest you write your own code and populate the table yourself.

There are plenty of examples on the forum showing how to load a JTable with data from a ResultSet . Just search for examples using those two class names as your keywords.

Or you can check outTable From Database which shows how you can use the DefaultTableModel to load rows of data from the ResultSet .
