在 JNLP 中加载 bcprov-jdk15on-1.50.jar 时出现问题

Question

所以我正在尝试使用运行 JNLP 中的一个项目，该项目使用外部 jar 来提供加密。当 JNLP 为运行时，我得到以下异常

com.sun.deploy.net.FailedDownloadException: Unable to load resource: http://localhost:8080/../lib/bcprov-jdk15on-1.50.jar
at com.sun.deploy.net.DownloadEngine.actionDownload(Unknown Source)

以及下面的包装异常

java.io.IOException: invalid SHA1 signature file digest for org/bouncycastle/...

jar 是问题被指定为 JNLP 文件

<jar href="lib/bcprov-jdk15on-1.50.jar"/>

在没有 jar 的情况下，项目启动得很好，但是需要加密的部分失败了，所以我相当有信心这是 JNLP 规范的问题。关于修复有什么想法吗？

Answer 1

从 jar 的 meta-inf 中删除签名并重新签名
