I have embedded an applet (jar file)in a html page

现在，当我尝试访问网页时，出现以下错误。

<APPLET CODE="com.xxx.tru.ReadNFCSerialNumber" NAME="Read" ID="Read" MAYSCRIPT alt="Photo Id"   ARCHIVE="\test.jar, \ojdbc14.signed.jar, \ojdbc14_g.signed.jar" WIDTH="100%"  HEIGHT="100%"  HSPACE="1"  VSPACE="1">
</APPLET>




load: class com.xxx.tru.ReadNFCSerialNumber not found.

我究竟做错了什么？？

Web 浏览器正在尝试从 URIhttp://localhost/popit/POPit/com/xxx/tru/ReadNFCSerialNumber.class而不是 jar 文件加载您的类。该ARCHIVE属性的内容对我来说看起来很可疑。它真的应该是一个逗号和空格分隔的列表吗？此外，文件名前面的反斜杠看起来很可疑：

ARCHIVE="\test.jar, \ojdbc14.signed.jar, \ojdbc14_g.signed.jar"

我建议您研究修复该ARCHIVE属性，然后查看 Web 浏览器是否会按照您的意愿从 jar 中加载类文件。

缺少 CODEBASE 属性。只是一个想法。代码库
