回答1:

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
