I am making a database search GUI for a CCG. I have a large GUI with JTextFields, JComboBoxes, JButtons, etc. When the user presses search, the program queries the MySQL database based on input from the user and displays the results in a JTable. The search is working great and returning the correct information. However, the final column of the database is a String that contains the file name of an image (png) for each record. I am having trouble getting the table to display the last column as an Image.

try {
            Class.forName("com.mysql.jdbc.Driver");
            conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/" + dbName, dbUsername, dbPassword);
            Statement sqlState = conn.createStatement();
            String selectStuff = "SELECT * FROM ...";
            rs = sqlState.executeQuery(selectStuff);
 
            Object[] tempRow;
 
 
// --------------------------------------------------------------
//             ImageIcon testIcon = new ImageIcon("test.png");
// --------------------------------------------------------------
 
            while(rs.next()){
                tempRow = new Object[] {rs.getString(3), rs.getString(4), rs.getString(10), rs.getString(6),
                    rs.getString(5), rs.getString(7), rs.getString(8), rs.getString(9), rs.getString(11),
                    rs.getString(12), rs.getString(13), rs.getString(14), rs.getString(15), rs.getString(16),
                    rs.getString(17), rs.getString(18), rs.getString(19),  rs.getString(42) };
                dTableModel.addRow(tempRow);
 
            }
}

The final column "rs.getString(42)" is the String that I want to turn into an ImageIcon.

Even when I try to manually set the value as an Icon by adding...
ImageIcon testIcon = new ImageIcon("test.png");
...and changing...
rs.getString(42)
 
to
 
testIcon
...I still can't get it to work. The last column of the table just spits out "test.png".

I've searched all over the internet and tried overriding the getColumnClass, but I had no luck there either.

I'm able to read in the String of the filename from MySQL. How do I get Java to recognize/convert this to an ImageIcon?
