bouncycastle 运行错误？

myeclipse 10.0
新建一个 java project.
JRE选javaSE-1.6

需要的3个jar包：bcmail-jdk16-146.jar，bcprov-ext-jdk15on-147.jar，bcprov-jdk16-146.jar
调用顺序也是如此。

按照http://blog.163.com/11_gying/blog/static/4067301220134293350972/文章写的。

下列程序出现如下问题：

why? --------------------编程问答-------------------- 看异常应该是JAR不对，是不是jar不是你的操作系统的？(32 or 64位)

猜测

--------------------编程问答-------------------- 应该是调用的JAR版本不一致造成。

比如：前一版本有setSerialNumber(Long l)方法，后面版本又去掉了，而调用的地方还没有相应的变化。

但是只要JAR版本一致没有问题，那就应该不会出现这样的严重错误。再或者是你放了2个版本的JAR再程序里，造成这种问题。 --------------------编程问答-------------------- 你的包放错了，应该放bcmail-jdk16-146.jar，bcprov-ext-jdk15on-147.jar或者bcprov-jdk15on-147.jar ，bcprov-jdk16-146.jar。下载资源网址：http://central.maven.org/maven2/org/bouncycastle/[size=16px][/size]
