java - Firefox 52.4.1 上的 Java Applet “ClassNotFoundException”

问题描述

我们需要在 Firefox 52.4.1（与 Java Applet 兼容的最新版本）和 Internet Explorer 11 上运行使用 Java 8 Applet（生病）的旧 Web 应用程序。

该小程序基于 Java 8 并由 Apache Tomcat 服务器分发。它经过签名和混淆（Proguard）。

用户通过智能卡的 SSL 相互身份验证连接到网站（客户端需要 PKCS11 模块才能从智能卡获取证书）。SSL 相互身份验证也通过 Java Applet 完成。

所有证书都由添加在每个浏览器、Windows 和 Java 证书存储中的权限签名。

这里的HTML代码：

<object classid='clsid:8AD9C840-044E-11D1-B3E9-00805F499D93' id='AsapiObject'>
    <param name='archive' value='../../../applet/myapplet.jar'/>
    <param name='code' value='main.package.Main'/>
    <param name='name' value='My Applet'/>
    <param name='mayscript' value='true'/>
    <comment>
        <applet id='AsapiApplet'
                name='My Applet'
                archive='../../../applet/myapplet.jar'
                code='main.package.Main'
                MAYSCRIPT="MAYSCRIPT">
        </applet>
    </comment>
</object>

（遵循https://docs.oracle.com/javase/8/docs/technotes/guides/jweb/applet/using_tags.html#applet的建议）

它在 IE 11 上运行良好，在 Mozilla Firefox 52.4.1 上运行良好。两者都使用相同的JRE。

在 Mozilla Firefox 52.4.1 上，我有一个 Java 异常：

java.lang.ClassNotFoundException: main.package.Main
    at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)

在这个例外之前，我有一个handshake failure exception：

我认为 Firefox 没有从智能卡正确导入客户端证书。

编辑：Java 控制台中还有另外两条有趣的行：

security: Accessing keys and certificate in Mozilla user profile: null
security: JSS is not configured

通过增加调试模式（-Djavax.net.debug=all），我看到：

IE浏览器：

*** ServerHelloDone

[read] MD5 and SHA1 hashes:  len = 4
0000: 0E 00 00 00                                        ....
ssl: KeyMgr: getting aliases: [XXXXXXX (verified: OK), YYYYYYYYYYYYYY]

...

火狐浏览器：

*** ServerHelloDone
[read] MD5 and SHA1 hashes:  len = 4
0000: 0E 00 00 00                                        ....
Warning: no suitable certificate found - continuing without client authentication
*** Certificate chain
<Empty>
***

我尝试/检查了很多东西：

检查 IAS_PKCS11 模块是否正确安装在 Firefox 上：

试图禁用plugins.click_to_play（https://support.mozilla.org/fr/questions/933135）
检查参数顺序<applet>（Java Applet 中使用 <object> 标记的 ClassNotFoundException）
清除缓存，添加 JRE 参数，重新安装 JRE ... ( https://support.mozilla.org/fr/questions/945083 )
已启用security.enterprise_roots.enabled（https://support.umbrella.com/hc/en-us/articles/115000669728-Configuring-Firefox-to-use-the-Windows-Certificate-Store）
使用<embed>或 <object>代替 <applet>。
在 Java 配置中的高级安全参数中尝试了很多组合
禁用了一些安全检查（CRL 等）。
编辑：根据JDK-6975851、JSS doc、NSS 版本，我使用VS2019 + Windows Kit 10 工具和库、Java 8 构建了基于NSS 3.28.3和NSPR 4.13.1的 JSS_4_4_20170313。我已经安装了 DLL 文件（jss4. dll、libplc4.dll、libnspr4.dll、libplds4.dll）在 Mozilla Firefox 目录和 jre_path/lib/ext 目录中的 jss4.jar。在所有这些努力之后没有成功...... :(

我真的需要帮助。

任何想法？（我不能将小程序切换到另一个东西 - 我没有这个选择）
