Answer 1

Parse error in application web.xml file at jndi:/localhost/test.myeclipse.bak/WEB-INF/web.xml意思是你的 web.xml 这个文件是错误的，无法解析。

Answer 2

Parse error in application web.xml file at jndi:/localhost/test.myeclipse.bak/WEB-INF/web.xml
org.xml.sax.SAXParseException: The processing instruction target matching "[xX][mM][lL]" is not allowed.
:/localhost/test.myeclipse.bak/WEB-INF/web.xml
你的项目怎么部署的啊 ？直接复制到webapp下 ，还是在server.xml中配置 ？

Answer 3

我的web.xml就这么些话
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <servlet>
    <description>This is the description of my J2EE component</description>
    <display-name>This is the display name of my J2EE component</display-name>
    <servlet-name>Login</servlet-name>
    <servlet-class>cxl.test.Login</servlet-class>
  </servlet>  <servlet-mapping>
    <servlet-name>Login</servlet-name>
    <url-pattern>/servlet/Login</url-pattern>
  </servlet-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>我部署我以前做好的工程 启动服务器都会报这个错误了。。xml无法解析 。。以前没有的

Answer 4

myeclipse里部署不是只要点几下就好了嘛- -

Answer 5

从你使用的Tomcat安装目录下，有个conf子目录，里面找到web.xml。以那个为基础来删改，彻底抛弃你现在这个web.xml，确保版本没问题。注意不要用EditPlus。

Answer 6

+老兄，你的项目名字很是给力 ：
严重: Context [/test.myeclipse.bak] startup failed due to previous errors

Answer 7

是以tomcat安装目录下的conf子目录里的web.xml 作为模板 修改我现在这个工程"webroot"-"WEB-INF"下的web.xml吗?是这个意思吗。

Answer 8

是的，主要是如果要以你现有xml为基础慢慢排查问题，会比较繁琐；论坛沟通起来也比较的效率低。所以一般来说以一个标准模板来修改会来得快些。

Answer 9

/localhost/test.myeclipse.bak/WEB-INF/web.xml  这个文件里的配置有问题 你检查下标签是否配对个人技术博客http://www.happyalaric.com
