如何解决JCOP J3A系列卡是否支持int数据类型？
我正在使用最新的Eclipse Jcop工具进行Java卡小程序开发。我需要在卡中存储大整数值，因此我在Applet中使用了INTEGER数据类型（int）来保持平衡。它正在编译，没有任何错误，但是在将CAP文件上传到Jcop J3A081卡时出现错误6A80。我已经尝试了GP 2.1.1，GP 2.2.1，JDK 2.2.2，JDK 3.0.4库的所有组合，但遇到相同的错误。
J3A / J2A系列卡是否支持int数据类型变量和JCint库？如果是，该如何解决？
Applet源代码：
注意：如果我删除int数据类型变量和JCint引用，则不会出现错误。

否，这些卡不支持int类型。要完全确定，只需向NXP索取数据表或用户手册，如果没有，请直接问他们。
如果您想支持更大的数据类型，那么这当然是可能的，但是您必须自己对其进行编程。在那种情况下，将对象存储在持久性内存中的事实当然不会有任何帮助，而是it can be done。
否则，这取决于您需要哪种整数支持。仅加法或减法就很容易在逐个字节的基础上实现。出于加密目的，您可能需要更深入地研究。有时，您还可以使用现有的API（例如DH密钥协议）来执行例如模幂。例如，有一些库可以执行椭圆曲线计算（需要大整数）。
