Tomcat-404找不到页面问题

Question

当我使用eclipse启动Tomcat9，然后导航到http：//localhost:8080时，它会给出404页的not found并抛出错误：“origin server dot find a current representation for the target resource or is not welligen to display that ixist”。但是，当我转到tomcat目录并使用Tomcat9w.exe启动进程，然后执行http：//localhost:8080时，页面会完美显示。可能有什么问题？

I see the tomcat server in eclipse is started without any problem but can not reach to default website..

THanks

您的“http 404：File not found”可能意味着您的Eclipse项目中缺少一个“index.jsp”。

从Eclipse运行Tomcat与从命令提示符（或者作为Windows服务）运行Tomcat不同。

即使您指向同一个Tomcat安装(Eclipse>Services>Add)，Eclipse也将从“tomcat9w.exe”这个不同的子文件夹中执行。

您可以在发布的日志中看到这一点:c:\users\vijay\eclipse-workspace\.metadata\.plugins\org.eclipse.wst.server.core。试着从两种方式开始，并比较“catalina_base”。

谢谢你的补充信息。具体地说：

>

问：这是成功启动Tomcat，对吗？可能是运行Tomcat9w.exe的结果，对吗？

除非Tomcat“找不到”请求的资源，否则您将无法获得HTTP 404。在这里，该资源是“/”。这意味着它希望找到一个“索引文件”，如“index.html”、“index.jsp”或等效文件。

对于Eclipse项目，这意味着“webapp”文件夹根目录中的“index.jsp”。

问题：

问：上述陈述1）和2）正确吗？

问：您的tomcat9w.exe“启动是否打印CATALINA_BASE和port#？如果是，请将它们复制/粘贴到您的原始文章中。

问：您的Eclipse日志是否打印任何错误消息？如果是的话，请将它们复制/粘贴到你原来的帖子中。
