java - EJB 2.1 类转换异常

Question

下面是我的代码

Properties localProperties = new Properties();
      localProperties.setProperty("java.naming.factory.initial", "com.sun.enterprise.naming.SerialInitContextFactory");
      localProperties.setProperty("java.naming.factory.url.pkgs", "com.sun.enterprise.naming");
      localProperties.setProperty("java.naming.factory.state", "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");
      localProperties.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
      localProperties.setProperty("org.omg.CORBA.ORBInitialPort", "3700");
      InitialContext localInitialContext = new InitialContext(localProperties);
      SanityAutomationAvailabilityMain localSanityAutomationAvailabilityMain = (SanityAutomationAvailabilityMain)localInitialContext.lookup("ejb/com/cw/wad/sanity/ejb/session/interfaces/SanityAutomationAvailabilityMain");

我使用上面的代码得到了一个类广播异常。知道我可能做错了什么吗？谢谢。

您尝试转换为 (SanityAutomationAvailabilityMain) 并得到类转换异常，那么无论您尝试转换的值是什么类型，都与 SanityAutomationAvailabilityMain 不兼容。
