applet NullPointerException
[英]applet NullPointerException
问题描述
I've been working on a game in an applet. 
我一直在applet中开展游戏。 In Eclipse it has been working completely fine, but when I sign it and load it in my browser, it throws a NullPointerException, without any further information. 在Eclipse中它已经完全正常工作，但是当我签名并在浏览器中加载它时，它会抛出NullPointerException，而没有任何进一步的信息。 What can I do? 我能做什么？

You don't give very much information here, but I can make a guess that you are calling getAppletContext and it is returning null, because the browser's java implementation is broken. 你在这里没有提供太多的信息，但是我可以猜测你正在调用getAppletContext并且它返回null，因为浏览器的java实现被破坏了。 Try the applet viewer, and try a different browser, and see if it works there. 尝试applet查看器，尝试使用其他浏览器，看看它是否有效。

That happen to me once. 这发生在我身上一次。 You'll need to go to: 你需要去：
- Configure Java. 配置Java。
- Security. 安全。
- Exception List 例外清单
- Edit the list adding the directory of your applet. 编辑添加applet目录的列表。
- Security.
This, I think, should fix the problem! 我认为，这应该解决问题！
