Iv. using MAVEN and building Javaweb projects with Eclipse

The environment has already been set up, and we'll get it again.

1. Build Javaweb project with Maven

(1), type the following command:

$ MVN archetype:generate-dgroupid=com.holytax.wg-dartifactid=mvnwenapp-darchetypeartifactid= Maven-archetype-webapp-dinteractivemode=false

(2), view the resulting project structure layout:

.| ____mvnwebapp| | ____pom.xml| | ____src| | | ____main| | | | ____resources| | | | ____webapp| | | | | ____index.jsp| | | | | ____web-INF| | | | | | ____web.xml

(3) Modify the Pom.xml update to allow the existing Web. XML to support Servlet 2.5 (the default Servlet2.3 is too old)

Pom.xml
