JBOSS:EJB如何修复java。朗。反思。未声明的HrowableException？

1 年，4 月 Questions & Answers 9036

在bean中，我尝试列出使用此方法的所有文章

public List<Article> listerLesArticles() {
    javax.persistence.Query req = manager.createQuery("select * from Article");
    return req.getResultList();
}

当我调用该方法时，从客户机

public void lister() {
    List<Article> arr = epicerie.listerLesArticles();
    System.out.println(" ");
    Iterator<Article> iterator =  arr.iterator();
    while (iterator.hasNext()) {
        Article unArticle=iterator.next();
        System.out.println(unArticle.getCode());
    }
    System.exit(0);
}

但是我得到了这个Exception：
