Applet表示，尽管已确认该类不存在，但该类不存在如何指定默认的类路径？

问题描述

Applet在大多数浏览器中不再起作用，因此我尝试改为在本地运行WebTransceiver.jar ...例如https://www.allstarlink.org/portal/webtransceiver.php?node=28238在页面源中具有applet描述符：

<applet id="WebTransceiver" height="400" width="440" codebase="https://www.allstarlink.org/portal/" archive="WebTransceiver.jar" code="WebTransceiver.class" mayscript>
  <param name="debug" value="0"/>
  <param name="user" value="allstar-public"/>
  <param name="pass" value="allstar"/>
  <param name="host" value="something:4569"/>
  <param name="callingNo" value="something...."/>
  <param name="callingName" value="something"/>
  <param name="callSign" value="mycallsign...."/>
  <param name="permissions" value="all-permissions" />
</applet>

具有应该可以让我的帐户连接的属性。我将其放入与WebTransceiver.jar相同目录中的文件“ apprun”中，然后运行：

appletviewer ./apprun

现在出现错误：

$ appletviewer ./apprun 
Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on

java.lang.ClassNotFoundException: WebTransceiver.class

显然拥有此类：

更新 -似乎必须删除codebase = ... url，然后它将在本地运行。奇。但是它仍然无法正常工作。
