Question

我创建了applet并使用bouncycastle类进行数字证书。

我已经对java 8 101进行了一些更改并签署了这个jar

但更改后会抛出异常。

请帮我解决这个问题。

Answer 1

已解决

感谢所有人我尝试了很多东西，但没有找到任何解决方案。最后我尝试了下面的工作。

我做了以下更改并为我工作。

新的jar文件版本是lib文件夹中的bcprov-ext-jdk15on-1.47.jar，并在MANIFEST.MF中为这个jar文件创建条目

在MANIFEST.MF进行了更改之后，我已经签署了 bcprov-ext-jdk15on-1.47.jar 和 applet.jar 文件，并为我工作。

感谢。

Answer 2

你使用的是什么版本的充气城堡？你尝试过最新版的吗？还请检查您的jdk是32位还是64位。希望这会有所帮助。
