希望最新的Java运行时（1.5或1.6）是支持使用Internet Explorer Web堆栈下载.jar文件的applet插件吗？我问的原因是我在Fiddler看不到请求。更多背景 - 我正在尝试解决此错误：

您可以将JVM配置为使用Fiddler进行联网：http://www.fiddlerbook.com/fiddler/help/hookup.asp#Q-JavaTraffic

Answer 2

//指定代理设置
  sysProperties.put（ “ProxyHost的”， “为myhost”）;
  sysProperties.put（ “proxyPort”， “MyPort上”）;
  sysProperties.put（“proxySet”，“true”）;

如果你知道“myhost”和“myport”是什么意思，那就太好了。

尝试使用localhost或127.0.0.1仍然不适合我： - （

Java Applets，Internet Explorer和Fiddler
