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

我创建了applet并使用bouncycastle类作为数字证书

我对Java8101做了一些更改，并在这个jar上签名

但更改后将抛出以下异常

请帮我解决这个问题。

您使用的是什么版本的bouncy castle？你试过最新的吗？还请检查您的jdk是32位还是64位。希望这有帮助。

多谢大家 我尝试了很多东西，但没有找到任何解决办法。最后我尝试了下面的方法，效果很好

我做了以下的改变和它对我的工作

添加的新jar文件版本是lib文件夹中的bcprov-ext-jdk15on-1.47.jar，并在MANIFEST.MF中为此jar文件创建条目

在MANIFEST.MF中进行更改后，我已签署了bcprov-ext-jdk15on-1.47.jar和applet.jar文件及其对我的工作

谢谢。

Classloader找不到

org.bouncycastle.asn1.ASN1ObjectIdentifier

。您是否在小程序部署中包含了

bcprov-jdk15on.1xx.jar

？是的，我添加了这个。请检查小程序描述符类加载器未找到

org.bouncycastle.asn1.ASN1ObjectIdentifier

中的相应设置。您是否在小程序部署中包含了

bcprov-jdk15on.1xx.jar

？是的，我添加了这个。检查小程序描述符中的适当设置。请接受此解决方案以指示其他人此问题已解决…这是我案例的解决方案请接受此解决方案以指示其他人此问题已解决解决了…这就是我的案子的解决方案
