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

Question

所以我尝试在 JNLP 中运行一个项目，该项目使用外部 jar 来提供加密。运行 JNLP 时出现以下异常

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)

at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)
at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

以及以下包装的异常

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

问题是 jar 被指定为 JNLP 文件

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

如果没有 jar，项目启动得很好，但需要加密的部分会失败，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
