Calling a Java application

The application clock.vxml prompts the user to ask for the time of day or today's date. The <object> element calls the applet clock.java, which returns the time or date. The grammar clock.grxml supports the application.

/**
 * Class Clock represents a clock maintaining both time of day and
 * current date. Applications can call setMode to determine the mode
 * to return the clock value in. The mode can be DAY, DATE, MONTH, TIME.
 * The default mode is DATE. After setting the mode the application can
 * call getCurrent to obtain the current clock value for that mode.
 * If the application doesn't call setLocale the default local is used.
