java.lang.ClassNotFoundException[JavaFx-ObjectProperty]

我在aws服务器上的tomcat上设置了一个Web服务

该代码引发一个异常：

23-Jan-2015 08:44:07.941 SEVERE [http-nio-8080-exec-4] null.null javafx/beans/property/ObjectProperty

位于scrabble.webService.ScrabbleWS.createScrabbleGame（ScrabbleWS.java:151）
位于scrabble.webService.ScrabbleWS.createGame（ScrabbleWS.java:84）

客户端调用构造函数来创建新游戏：

public final class GameManager {


private Board board;
private LettersBank bank;
private String gameName;

private Player[] players;
private final ArrayList<String> resignedPlayers;
private int currentPlayerIndex = 0;

final private ObjectProperty<Player> currentPlayerProperty; <<<<

final private BooleanProperty gameFinishedProperty;
private boolean isLastRound = false;
private boolean isEndGame = false;

public GameManager() {
    this.computerFinishedPlayingProperty = new SimpleBooleanProperty();
    this.gameFinishedProperty = new SimpleBooleanProperty(false);
    this.currentPlayerProperty = new SimpleObjectProperty<Player>();
    this.board = null;
    this.gameName = "";
    this.resignedPlayers = new ArrayList<String>();
    this.bank = new LettersBank();
    computerFinishedPlayingProperty.set(false);
}

行中写了什么？72？gameEngine=new GameManager（）；aws服务器上运行的java版本是什么？

？您是对的，它是java 6。如何在aws上使用java 8制作tomcat服务器？您使用的是aws EC2 Linux吗？
