恶心的xml

1.将项目部署到tomcat之外

通过Tomcat目录下的

conf/Catalina/localhost/

新建projectname.xml的方式，可以将项目部署到tomcat的外部，该文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>

</Context>

2. 坑爹的web-app标签属性

检查web.xml红色部分,避免类不被tomcat访问

tomcat7能正常访问classes

<?xml version="1.0" encoding="UTF-8"?>

<web-app 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_3_0.xsd"

version="3.0" metadata-complete="true">

<display-name>web服务器</display-name>

使用Servlet实现HelloWorld的例子

</description>

<servlet>

<servlet-name>Servers</servlet-name>

<servlet-class>com.web.Servers</servlet-class>

<init-param>

<param-name>version</param-name>

<param-value>1.0</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<url-pattern>/Servers</url-pattern>

</servlet-mapping>

<servlet-name>Config</servlet-name>

<servlet-class>com.web.Config</servlet-class>

<url-pattern>/Config</url-pattern>

<servlet-name>Notice</servlet-name>

<servlet-class>com.web.Notice</servlet-class>

<url-pattern>/Notice</url-pattern>

<servlet-name>Login</servlet-name>

<servlet-class>com.web.Login</servlet-class>

<url-pattern>/Login</url-pattern>

<servlet-name>Shop</servlet-name>

<servlet-class>com.web.Shop</servlet-class>

<url-pattern>/Shop</url-pattern>

<servlet-name>Verify</servlet-name>

<servlet-class>com.web.Verify</servlet-class>

<url-pattern>/Verify</url-pattern>

<session-config>

<session-timeout>100</session-timeout>

</session-config>

</web-app>

tomcat7不能正常访问classes

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee"

xmlns:web_1="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

version="2.5">
