這個 ejb 異常是什么意思？

Question

我試圖執行使用 EJB 的應用程序，但出現了以下異常：

javax.ejb.EJBException: java.rmi.MarshalException: CORBA MARSHAL 1330446346 Maybe; nested exception is:

有誰知道，如何解決？ 我有 glassfish 4 和 jdk 1.7.0_60。

申請代碼：

package com.apress.javaee6.chapter06;

import javax.ejb.*;

public class Main {
    
    @EJB
    private static BookEJBRemote bookEJB;
    
    public static void main(String[] args) {
        Book book = new Book();
        book.setTitle("The Hitchhiker's Guide to the Galaxy");
        book.setPrice(12.5F);
        book.setDescription("Scifi book created by Douglas Adams");
        book.setIsbn("1-84023-742-2");
        book.setNbOfPage(354);
        book.setIllustrations(false);
        
        bookEJB.createBook(book);
        
    }
}

該錯誤消息表明您正面臨由JDK 1.7_55和JDK 1.7_60引起的此錯誤。 要解決它，您必須降級到JDK 1.7_51 ，安裝JDK 8或等待不會導致此錯誤的較新版本的JDK 7 。

無論如何，您嘗試做的事情以這種方式是不可能的。 您不能在普通 Java 類（不受容器管理的類）中使用@EJB 。

如果要使用 bean，則必須通過 JNDI 檢索它。 查看GlassFish EJB 常見問題解答以了解這是如何完成的。
