Exception: java.lang.ClassNotFoundException: mettler**

我在jsp文件中使用的applet标签下面

**<applet name="mettler" code=mettler archive="RXTXComm.jar,mettler.jar" width="100" height="30"></applet>**

在上面的异常中，mettler也是我的类名和jar名。我将这些jar文件保存在WEB-Inf / lib文件夹下。

如果我在我项目的web文件夹下的jsp中使用这个applet标签工作正常，但是如果我在web / com中使用这个applet标签/在jsp中读取那么这不起作用。

请指导我可能出现的问题以及可以做些什么？

从jar调用applet类时java.lang.ClassNotFoundException
