造成原因：java.lang.NoClassDefFoundError：org / bouncycastle / asn1 / ASN1ObjectIdentifier

我创建了applet，并将bouncycastle类用于数字证书。

我对Java 8 101进行了一些更改并签署了这个jar

但更改后将抛出以下异常。

堆栈跟踪：

请帮助我解决这个问题。

解决

多亏了我所有的尝试，但没有找到任何解决方案。最后，我在下面尝试了一下，并且成功了。

我为我做了以下更改及其工作。

在lib文件夹中添加了新的jar文件版本为bcprov-ext-jdk15on-1.47.jar，并在MANIFEST.MF中为此jar文件创建了条目

在MANIFEST.MF中进行更改后，我已经为我签名了bcprov-ext-jdk15on-1.47.jar和applet.jar文件。

谢谢。
