尝试让小程序在实时服务器上工作
我构建的小程序在本地主机上运行良好,但是当我将其上传到服务器并查看 url 时,我收到这些 java 小程序错误: 在传输文件时,我是否可能错过了让小程序正常工作的额外步骤?

The applet I build runs well off my localhost but when I upload it to server and look at url I recive these java applet errors: Are there extra steps I may have missed to get the applet to work when transferring files?

您确定上传正确吗?
错误消息“不兼容的魔法值”显示无效的类文件。
您还可以检查是否可以从 URL 检索类文件而不会出现错误?如果服务器返回错误,则会出现类似的 Java 错误。尝试使用curl 或类似的东西检索类文件。
Are you sure the upload was correct?
The error message " Incompatible magic value" shows an invalid class file.
Can you also check, that the class file can be retrieved from the URL without error? If the server returns an error, a similar Java error will occur. Try to retrieve the class file with curl or something similar.
