How to edit a JTable row?

I want a tutorial or a method so that I can highlight a row in a Jtable which grabs its data from a mysql db , then click on edit button so it launches a form that I can use to edit the row and then save. I used a method that worked but it threw a lot of exceptions so I think it's a bad design.

Edit : I don't want to use binding yet . I want to write basic code that I can understand.

Edit 2 : Here's what I call to get the key I use in editing query .. I highlight the row and call this function :

int id = ((Number) model.getValueAt(jTable1.getSelectedRow(), 0)).intValue() ;

the function body wasn't written by me It's part of ResultSetTableModel file

 public Object getValueAt( int row, int column )
      throws IllegalStateException
   {
      // ensure database connection is available
      if ( !dbConnection.isConnectedToDatabase() )
         throw new IllegalStateException( "Not Connected to Database" );

      /开发者_如何学Go/ obtain a value at specified ResultSet row and column

      try
      {


          getResultSet().absolute( row + 1 );
         return getResultSet().getObject( column + 1 );
      } // end try
      catch ( SQLException sqlException )
      {
          System.out.println("Exception from here dude");
         sqlException.printStackTrace();
      } // end catch

      return ""; // if problems, return empty string object
       } // end method getValueAt

A resultset closed exception is thrown here and I know the reason is because I used the same resultset before to fill the table . So I want a different alternative.

See How to Use Tables. But it would be helpful if you could show your code.

If your problem is that your application throws a SQLException then you need to show your SQL-query and your database schema for that table.

See Table From Database. The "Table From Database Example" shows how you can create a DefaultTableModel from data in a ResultSet so you don't have to worry about this.
