TableExamplepublic class TableExample extends Object implements LayoutManagerA a UI around the JDBCAdaptor, allowing database data to be interactively
fetched, sorted and displayed using Swing.
NOTE: This example uses a modal dialog via the static convenience methods in
the JOptionPane. Use of modal dialogs requires JDK 1.1.4 or greater. |

void | activateConnectionDialog()Brigs up a JDialog using JOptionPane containing the connectionPanel.
If the user clicks on the 'Connect' button the connection is reset.

null, ConnectOptionNames, ConnectOptionNames[0]) == 0) {
