Smartcard 0x6f00转换Javacard可共享接口时出错

Smartcard 0x6f00转换Javacard可共享接口时出错,smartcard,javacard,Smartcard,Javacard,我尝试对两个不同的包使用SIO（可共享接口对象），以便将来更新小程序的业务逻辑。 我正在使用eclipse，我启动了两个不同的JavaCard应用程序，ClientSIOApplet和ServerSIOApplet。ClientSIOApplet中有一个名为appClient的包，ServerSIOApplet中有一个名为appServer的包。 此外，ClientApplet.java和ServerAppBankInterface.java是appClient和中的类 appServer中有S

问题是：

我在铸造接口时遇到问题：

ServerAppBankInterface bankInterface = (ServerAppBankInterface) sio;
在ClientApplet.java中

如果我删除该行中的Try Catch，我将收到0x6F00错误，

服务器小程序将提供该类型的可共享接口

appServer.ServerApplet <- appServer.ServerAppBankInterface <- javacard.framework.Shareable

appServer.ServerApplet以下是更新的代码
在我这边的JCIDE上运行良好

    你的意思是我应该在一个包中同时包含applet和一个项目？如果是，那么服务器小程序中的数据是否在删除客户端小程序后删除？也就是说，一个包中不同小程序的上下文是否不同？不，只有您的共享界面需要在
    appServer
    包的范围内。我无法使用两个应用程序获得最佳结果。因此，我尝试了一个javacard应用程序和一个名为pkgSIO的包，其中包含两个名为APPClient和AppServer的小程序以及一个名为ServerAppBankInterface的接口，AppServer实现了它。现在我得到了我想要的结果。删除AppClient并在预装包中再次安装后，我可以访问以前保存的数据。非常感谢您的帮助。还有一个问题，如果我有两个应用程序，其中两个包的名称相同，那么我应该为applet AID和package AIDs定义什么？app1-->打包（AID=0102030405）-->AppletClient（AID=010203040501）app2-->打包（AID=010203040506）-->AppletServer（AID=0102030405001）
