我在eclipse动态项目中运行一个Score and Score预留服务类，我创建了一个Web服务并运行它，但它给出错误代码The package javax.xml.namespace is accessible from more than one module: <unnamed>, java.xml。不知道如何处理此输出

记分班

package startAgain;

import javax.xml.bind.annotation.*;
@XmlType
@XmlAccessorType(XmlAccessType.FIELD)
public class Score {
public int wins, losses, ties;
}

ScoreServies类

package startAgain;

import javax.ejb.*;
import javax.jws.*;
@Stateless
@WebService
public class ScoreService {
private static Score score = new Score();
public Score updateScore (int wins, int losses, int ties) {
    score.wins = wins;
    score.losses = losses;
    score.ties = ties;
    return score;
}
@WebMethod(operationName="resetScore")
public void reset() {
score.wins = score.losses = score.ties = 0;
}
        public Score getScore() { return score; }
        public int increaseWins() { return score.wins++; }
        public int increaseTies() { return ++score.ties; }
        public int increaseLosses() { return ++score.losses; }
        public int getWins() { return score.wins; }
        public int getTies() { return score.ties; }
        public int getLosses() { return score.losses; }

}

有关清除此程序包的任何帮助javax.xml.name空间错误，谢谢
