You can also say
<input type="submit" name="p_action" value="Save">
<input type="submit" name="p_action" value="Done">
<input type="submit" name="p_action" value="Next">
<input type="submit" name="p_action" value="Previous">
and in the servlet say
public class AppConstants{
// constants class
public final static String PREVIOUS = "Previous";
public final static String DONE = "Done";
...
}
String action = request.getParameter ("p_action");
if (p_action != null){
if (p_action.equals(AppConstants.PREVIOUS)){
// do something
} else if ..
}
