web.xml常用模版

eclipse中使用maven-artchetype-webapp创建Maven项目时由于这个catalog比较老，用的servlet还是2.3的，这里收集了几个常用版本方便以后查阅:

Servlet 3.1

Java EE 7 XML schema, namespace is http://xmlns.jcp.org/xml/ns/javaee/

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> </web-app>

Servlet 3.0

Java EE 6 XML schema, namespace is http://java.sun.com/xml/ns/javaee

<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"> </web-app>

Servlet 2.5

Java EE 5 XML schema, namespace is http://java.sun.com/xml/ns/javaee

<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_2_5.xsd" version="2.5"> </web-app>

Servlet 2.4

J2EE 1.4 XML schema, namespace is http://java.sun.com/xml/ns/j2ee

<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4"> <display-name>Servlet 2.4 Web Application</display-name> </web-app>

Servlet 2.3

J2EE 1.3 DTDs schema. This web.xml file is too old, highly recommend you to upgrade it.

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Servlet 2.3 Web Application</display-name> </web-app>
