Question

我需要打包和分发使用java和DigitalPersona One-touch指纹SDK制作的指纹小程序。

目前，applet已经过测试并使用Netbeans 8

编译到jar中

要分发小程序，需要打包和签名，因为我一直在寻找互联网上似乎没有帮助

如何签署jar文件？
如果我在本地使用自生成密钥对jar文件进行签名，它是否可以在客户端浏览器中使用？

在Netbeans将applet编译为jar之后，我只是将它复制到html的同一目录中并在浏览器中调用它，如下所示：

<applet id="fpa"
    code="SensorApplet" archive="FingerprintApplet.jar"
    width="300" height="400">
</applet>

applet运行时出现以下错误

java.lang.noclassdeffounderror: com/digitalpersona/onetouch/capture/event/DPFPDataListener

Answer 1

How do i sign the jar files?

If I put that exact question into Google, the top hit is Signing JAR Files.

If I sign the jar files with self generated key locally, will it work in client browser?

Short answer, no. Long answer, nope. But even with a valid code signing certificate, it won't work in Chrome (they've removed all support for applets) and soon(?) won't be supported in IE or FF (at all - same deal as Chrome).

The only hope to get this applet on-screen for general users is to:

Sign it with a CA issued code signing certificate.
Launch it free floating (not embedded in a browser) using Java Web Start.

我找到了问题的解决方案

我能够让这个Applet在Firefox浏览器中运行，虽然它会弹出三个安全对话框，我只需要检查＆＃34;我接受......＆＃34;然后单击“运行”

我简单地将Netbeans配置为在编译applet时使用自签名证书对Jar进行签名。

然后我将所有jar库包含在applet的archive参数中，如下所示

<applet id="fpa"
    code="SensorApplet" archive="FingerprintApplet.jar, Jarlib1.jar, Jarlib2.jar, Jarlib3.jar"
    width="300" height="400">
</applet>
