eclipse - 服务器 Tomcat v7.0 无法启动

Question

我正在尝试更新 xml.file，但 Tomcat 一直在使用 Eclipse Kepler 崩溃我已经尝试在 2 台不同的 PC 上安装 Tomcat 7，但我不断收到相同的错误消息。我已经卸载并重新安装了 Eclipse 和 Tomcat，但还是一样。导致机器崩溃的xml文件中有代码。我有 1 个名为 index.jsp 的文件和另外 1 个名为 login.jsp 的文件

我尝试用/loginpage 替换 url-pattern loginpage 和斜杠但我得到了同样的错误。

在更新前有效的代码下方:

<?xml version="1.0" encoding="UTF-8"?>

下面的代码在更新后不起作用:

Answer 1

来自你的堆栈跟踪

Caused by: java.lang.IllegalArgumentException: JSP file login.jsp must start with a '/ 

标记 <jsp-file> from oracle docs says,

The full path to a JSP file within the Web application, relative to the Web application root directory.

Rhand answer提到的链接，来自该链接

The must start with a forward slash (/) if the JSP is in the application's root directory.

只需更改为

<jsp-file>/login.jsp</jsp-file>  

还有一件事，来自 web.xml working before update 你有

<url-pattern>/HelloTest</url-pattern>  

并且在 web.xml after update 你有

<url-pattern>HelloTest</url-pattern>  //missing /  
             ↑   

改正

<url-pattern>/HelloTest</url-pattern>
