启动 tomcat 服务器时出现 404，并且在 java 库路径上找不到 Tomcat 本机库答案

【问题标题】：404 on starting tomcat server and Tomcat Native Library not found on java library path启动 tomcat 服务器时出现 404，并且在 java 库路径上找不到 Tomcat 本机库

【问题描述】：

所以我在 Eclipse 中在 win 32 位环境中启动了一个 Tomcat 网络服务器。我在指向localhost:8080/HippoWebApp 时找不到404 webapp。该页面有一些信息：

The requested resource (/HippoWebApp/) is not available.

Eclipse 控制台说：

Nov 30, 2012 10:56:49 AM org.apache.catalina.core.AprLifecycleListener init

INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Java\jdk1.6.0_26-32\bin;C:\WINDOWS\Sun\Java\bin;C:\WINDOWS\system32

我做错了什么？我阅读了 APR，它似乎是它的 harmless warning

在.settings/org.eclipse.wst.common.component中设置上下文路径的文件

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

【问题讨论】：

标签： sql-server apache tomcat http-status-code-404

【解决方案1】：

APR 警告不是 HTTP 404 的原因。您能否发布整个 Tomcat 启动日志？应用程序是否正确启动？设置上下文路径了吗？

如果我没记错的话，上下文路径是在 .settings 文件夹中的文件 org.eclipse.wst.common.component 中设置的。
