尝试在Tomcat上部署我的Web应用程序的war文件时，获取HTTP Status 404错误 [英] Getting HTTP Status 404 error when trying to deploy war file of my web application on tomcat

问题描述

我已经在Eclipse中使用JSP创建了一个名为JSP_web_application_01的Web应用程序，我在ubuntu 12.04 LTS。我在WebContent目录下有index.jsp文件。我使用命令提示符创建了.war文件，为了部署它，将其放在tomcat的webapps文件夹中，并使用sudo $ CATALINA_HOME / bin / shutdown.sh命令停止tomcat，并再次由sudo $ CATALINA_HOME / bin / startup.sh

它膨胀了.war文件（JSP_web_application_01.war）并创建了JSP_web_application_01文件夹结构，除了我所得到的一切都是一个http 404状态码当我尝试从浏览器访问它：

  http：// localhost：8080 / JSP_web_application_01 / 
  

我得到这个：

  HTTP状态404  -  / JSP_web_application_01 / 
类型状态报告
消息/ JSP_web_application_01 / 
描述请求的资源不可用。 
 Apache Tomcat / 7.0.47 
  

这是我的WebContent里面的web.xml文件/ WEB-INF文件夹

 <？xml version =1.0encoding =UTF-8？> 
< web-app xmlns：xsi =http://www.w3.org/2001/XMLSchema-instancexmlns =http://java.sun.com/xml/ns/javaeexsi ：schemaLocation =http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsdid =WebApp_IDversion =3.0 >

< welcome-file> default.htm< / welcome-file> 
< welcome-file> default.jsp< / welcome-file>

< / web-app> 
  

这是我第一次尝试托管Web应用程序。所以，任何帮助将不胜感激。

解决方案

检查项目文件必须在JSP_web_application_01特别是index.jsp下进行解压缩。如果正确，请重新启动Web服务器，尾部日志文件在$ CATALINA_HOME / logs下，检查开始信息是否正确。

I know this questions was asked earlier yet any of the answers given did not fix my problem.

I have created a web application named JSP_web_application_01 using JSP in Eclipse and I'm on ubuntu 12.04 LTS. I have index.jsp file inside WebContent directory. I made the .war file of it using command prompt and in order to deploy it I put it inside the webapps folder of tomcat and stopped tomcat using the command sudo $CATALINA_HOME/bin/shutdown.sh and again started it by sudo $CATALINA_HOME/bin/startup.sh

And it inflated the .war file(JSP_web_application_01.war) and created the JSP_web_application_01 folder structure and everything but what I get is an http 404 status code when I try to access it from the browser using :

http://localhost:8080/JSP_web_application_01/

I get this :

HTTP Status 404 - /JSP_web_application_01/
type Status report
message /JSP_web_application_01/
description The requested resource is not available.
Apache Tomcat/7.0.47

This is my web.xml file that is inside WebContent/WEB-INF folder

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
    <display-name>JSP_web_application_01</display-name>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>
</web-app>

This is my first time of trying to host a web application. So, any help would be much appreciated.

解决方案

Check the project files must be decompressed under JSP_web_application_01 especially index.jsp. If it correct, restart web server, tail the log file under $CATALINA_HOME/logs, check the start info correct.
