Simple, set the layout manager for panel as BorderLayout or simple add the JScrollPane (pane) directly to the frame, which uses a BorderLayout by default

Take a look at Laying Out Components Within a Container for more details

cool..you do not need to write so many lines of code to display a file.Just download the jar file rs2xml and add it to your project library.

Note: This will be useful if you are using netbeans

How to use it?

  • create the table in backend
  • download rs2xml jar file
  • Add it to the project library
  • drag the jtable from the swing controls to your jframe

Now write the following code as follows:

write ur query:

        ps=con.prepareStatement("select * from register");       
        ResultSet r=ps.executeQuery();
        jTable1.setModel(DbUtils.resultSetToTableModel(r)); //display the register table
