Question

我将Tomcat 8.5与Eclipse集成，但是当我启动服务器并转到http://localhost:8080或http://localhost:8080/psite（使用index.html配置的Eclipse项目）时，我每次都会收到404错误。

我试图＆＃34;切换位置＆＃34; - 没有工作。
＆＃34;服务器配置＆＃34; Eclipse（Neon）上缺少服务器概述屏幕中的部分。
在Window-＆gt; Preferences-＆gt;运行时环境下：我使用＆＃34;搜索＆＃34;找到Tomcat安装目录。如果我使用＆＃34;添加＆＃34; ＆＃34;下一个＆＃34;按钮是perma-greyed-out，我无法配置路径。
日志文件夹中没有创建日志。
使用安装程序安装tomcat，在那里配置JRE路径。当我使用tomcat核心提取的zip而不是安装程序时，会发生相同的行为。
更新 - 如果我从cmd启动Tomcat，我可以访问localhost：8080就好了（感谢Sasikumar） - 但是我的Eclipse出了什么问题？我需要重新安装吗？

Answer 1

当您从eclipse启动tomcat时，它会更改CATALINA_BASE：

-Dcatalina.base=C:\Users\Nadav\Desktop\Workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0

这样，你永远不会在eclipse中运行管理器应用程序：它完全是空的。默认情况下，您部署了一个空的ROOT应用程序。现在，我怀疑您尚未在“服务器”视图中将您的应用添加到服务器（右键单击您的tomat并选择＆＃34;添加或删除＆＃34;）。控制台输出应该提到在这种情况下部署了psite。您还可以访问catalina基本文件夹并查看应用的 wtpwebapps 文件夹。

Answer 2

试试这个。

确保您已使用server view>add或Run As-＆gt;在服务器上运行

将项目 psite 添加到tomcat8.5

现在让package explorer（或）项目资源管理器找到Server文件夹。

展开它，然后在tomcat8.5的文件夹中找到server.xml。

现在打开sever.xml，在文件末尾确保您已完成此配置。

<Context docBase="psite" path="/psite" reloadable="true" source="org.eclipse.jst.j2ee.server:psite"/>

如果没有停止服务器修改它并启动服务器然后尝试。
