TOMCAT - HTTP状态404 [英] TOMCAT - HTTP Status 404

问题描述

我在eclipse中设置我的服务器，当我运行它时，控制台打印：

  mai 02，2013 4:05 ：13 PM org.apache.catalina.core.AprLifecycleListener init 
 INFO：在java.library.path中找不到基于APR的Apache Tomcat Native库，它允许生产环境中的最佳性能：C：\Program文件\Java\jre7\bin; C：\WINDOWS\Sun\Java\bin; C：\WINDOWS\system32; C：\WINDOWS; C：\WINDOWS\system32;ç ：\WINDOWS; C：\WINDOWS\System32\Wbem; c：\Program文件（x86）\Microsoft应用程序虚拟化客户端; c：\Program文件（x86）\打开文本\\ \\bin; C：\WINDOWS\System32\WindowsPowerShell\v1.0\; C：\Program Files\ThinkPad\Bluetooth Software\; C：\Program Files\ThinkPad\Bluetooth Software \syswow64 ;; C：\Program Files（x86）\Intel\OpenCL SDK\2.0\bin\x86; C：\Program文件（x86）\Intel\OpenCL SDK\2.0\bin\x64; C：\Program Files\Java\jre7\bin; C：\WorkspacePPL\apache-maven-3.0。 4\bin ;.

但是，如果我浏览 http：// localhost：8080 我得到：

  HTTP状态404  -  / 
 ------------------------------------------- -------------------------- 
类型状态报告
消息/ 
描述请求的资源不可用。 
  

我应该看到Tomcat的欢迎页面。

解决方案

1. 点击在窗口>显示视图>在服务器视图中右键单击服务器，选择属性。


2. 在常规面板中，单击切换位置按钮。


3. 位置：[工作区元数据]应替换为其他内容。


4. 双击打开服务器的概述屏幕


5. 在服务器位置选项卡中，选择使用Tomcat位置。


6. 保存配置并重新启动服务器。 $ b

在启动服务器之前，您可能需要按照上述步骤操作。因为服务器位置部分变灰 - 无法访问。

I set up my server in eclipse and when I run it the console prints:

mai 02, 2013 4:05:13 PM org.apache.catalina.core.AprLifecycleListener init

but then, if I browse http://localhost:8080 I get:

HTTP Status 404 - /
---------------------------------------------------------------------
type Status report
message /
description The requested resource is not available.

While I should see the Tomcat welcome page.

If I run Tomcat outside of eclipse I can reach the welcome page.

解决方案

1. Click on Window > Show view > Server or right click on the server in "Servers" view, select "Properties".
2. In the "General" panel, click on the "Switch Location" button.
3. The "Location: [workspace metadata]" should replace by something else.
4. Open the Overview screen for the server by double clicking it.
5. In the Server locations tab , select "Use Tomcat location".
6. Save the configurations and restart the Server.

You may want to follow the steps above before starting the server. Because server location section goes grayed-unreachable.
