问题是 “请求的资源（/main_servlet/）不可用。”

以下是源代码：

context.xml：

<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/main_servlet"/>

main_servlet.java、context.xml和web.xml的代码仅由NetBeans自动生成。我真的不明白为什么找不到来源。

非常感谢你

尝试使用以下URL访问您的代码：

http://(servername)/main_servlet/main_servlet 

      where (severname) is the name of the server on which your app is running.

这是必要的，因为您已经将应用程序上下文和servlet URL模式定义为“/main\u servlet”

或者-更好的解决方案是将应用程序上下文更改为其他类似“MyApp”的内容

非常感谢。我已经解决了！哦，谢谢。我已经打勾了！
