java - 使用 Java 7 启动 JNLP 时出现 NoSuchAlgorithmException

Question

升级到 Java 7 后，启动远程 jnlp 时，我在 Java 控制台中看到以下异常:

java.security.KeyStoreException: WIExplorerMy not found

此外，显示“错误。点击查看详细信息”的错误屏幕会出现约 2 秒，然后消失。

除此之外，一切似乎都正常运行。

对于 Java 6，一切都按预期工作。

如何解决？

Answer 1

我认为一些最新的 Java 7 更新已经废弃了一些加密方案，因此如果您在使用 Java 6 时使用其中一个，那将是一个完全正常的异常。

查看此 list of enhancements and changes for Java 7 :

Weak cipher suites deprecated

Per RFC 4346, RFC 5246, and RFC 5469, some cipher suites have been made obsolete and should not be used. These obsolete suites are all disabled by default in SunJSSE. For details, consult the cipher suite lists in the documentation about the SunJSSE provider.

也就是说，这可以解释 NoSuchAlgorithmException，但错误消息似乎提到了有关丢失 keystore 的内容，因此这可能是无关的，我们需要您提供 SSCCE或任何足够接近的东西。
