小程序导致的WeightingScale问题
小程序导致的WeightingScale问题
提问于 2017-10-03 18:01:27
在我们的应用程序中，我们加载applet从机器的串口和USB端口读取数据。小程序代码在过去这么多年中运行良好，但当我们迁移到IE 11.0.44版本时，浏览器在加载小程序时挂起了2到3分钟。这会引起问题。
下面是Java控制台的日志文件。你能帮我们解决这个问题吗？使用JRE版本1.7.0_80-B15JAVA HotSpot(TM)客户端VM的Java插件10.80.2.15

当小程序未正确加载或存在某些通信问题时，我们会收到classnotfound异常错误。
