所以，我几乎只是从eclipse中的servlet，jsp和apache tomcat开始。我正在做一个已经工作的项目，我不小心打开了一个html表单（用post发送数据到java方法）和eclipse里面的web编辑器（它不支持斯洛文尼亚字母ščćžđ，并且ecnoding搞砸了Uppon在默认编辑器中打开并修复混乱的编码，无法保存文件。它给了我一个USB编码的弹出窗口以及它如何需要为utf 8所以我只是单击是然后apache将加载否只是形式和方法，它甚至不会打开整个网站（索引等）..当我尝试在网上找到一些其他固定的，它给了我404,500和一堆其他错误..检查现在它甚至不会运行（我找到了web.xml文件中的问题 - 当它注释掉时，服务器运行但当然没有运行..）..
以下是错误消息：
