我想在TomEE Plus和Eclipse中使用一個帶有web應用程序項目的EJB項目。我可以在Web應用程序項目中使用無界面Bean，但是當我創建新的EJB項目時，在Web應用程序上配置構建路徑以包含EJB項目，TomEE將無法啓動。如何在TomEE Plus/Eclipse中使用Web應用程序項目創建/設置/使用EJB項目？
我將TomEE設置爲在Eclipse的TomEE屬性的服務器位置窗格中使用Tomcat安裝。如果我不這樣做，我甚至無法訪問與Servlet相同的包中的EJB。
的代碼很簡單：
package mypackage;
import java.io.IOException;
// Package containing remote interface and bean implementation
// Remaining imports omitted
import beans.* ;
@WebServlet("/HelloServlet")
public class HelloServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
@EJB
HelloSBNoI hb ; // The bean located within this project (same package as servlet)
@EJB
HelloBeanRemote hbfejb ; // The bean located in an ejb project
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html"); ;
response.getWriter().write("Hello From Servlet <br />");
response.getWriter().write("Hello From EJB in same package" + hb.from());
response.getWriter().write("<br />Hello From EJB in different project" +
hbfejb.sayHelloEJB());
}
}
和這裏的TomEE試圖啓動，但未能：

我花了幾個小時試圖弄清楚什麼看起來像一個簡單的配置錯誤！
