How to create sample vaadin application with maven 2.2.1

Step one
--------

Create maven project with typing the following command on your command line.


mvn archetype:create -DgroupId=com.sample.vaadin -DartifactId=SampleVaadin -DarchetypeArtifactId=maven-archetype-webapp

Here is the sample pom.xml

 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  
  <modelVersion>4.0.0</modelVersion>  
  <groupId>com.sample.vaadin</groupId>  
  <artifactId>SampleVaadin</artifactId>  
  <packaging>war</packaging>  
  <version>1.0-SNAPSHOT</version>  
  <name>SampleVaadin Maven Webapp</name>  
  <url>http://maven.apache.org</url>  
  <dependencies>  
   <dependency>  
    <groupId>junit</groupId>  
    <artifactId>junit</artifactId>  
    <version>3.8.1</version>  
    <scope>test</scope>  
   </dependency>  
  </dependencies>  
  <build>  
   <finalName>SampleVaadin</finalName>  
  </build>  
 </project>  

Step two
--------

Integrate jetty servlet container to vaadin project

Please update your pom.xml as follows:

 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  
  <modelVersion>4.0.0</modelVersion>  
  <groupId>com.sample.vaadin</groupId>  
  <artifactId>SampleVaadin</artifactId>  
  <packaging>war</packaging>  
  <version>1.0-SNAPSHOT</version>  
  <name>SampleVaadin Maven Webapp</name>  
  <url>http://maven.apache.org</url>  
  <dependencies>  
   <dependency>  
    <groupId>junit</groupId>  
    <artifactId>junit</artifactId>  
    <version>3.8.1</version>  
    <scope>test</scope>  
   </dependency>  
      <dependency>  
           <groupId>com.vaadin</groupId>  
           <artifactId>vaadin</artifactId>  
           <version>6.6.2</version>  
           <type>jar</type>  
           <scope>compile</scope>  
      </dependency>  
  </dependencies>  
  <build>  
   <finalName>SampleVaadin</finalName>  
      <plugins>  
        <plugin>  
          <groupId>org.mortbay.jetty</groupId>  
          <artifactId>maven-jetty-plugin</artifactId>  
     </plugin>  
           <plugin>  
                     <groupId>org.apache.maven.plugins</groupId>  
                     <artifactId>maven-compiler-plugin</artifactId>  
                     <version>2.3.2</version>  
                     <configuration>  
                          <source>1.6</source>  
                          <target>1.6</target>  
                     </configuration>  
           </plugin>  
   </plugins>  
  </build>       
 </project>  


*** You can test whether jetty is running by typing "mvn jetty:run"


Step tree
--------

Writing code under src/main/java/com/sample/vaadin/HelloVaadin.java

 /**  
 * This is the main class of the vaadin page  
 * @author gayan  
 *  
 * src/main/java/com/sample/vaadin/HelloVaadin.java  
 */  
 package com.sample.vaadin;  
 import com.vaadin.Application;  
 import com.vaadin.ui.*;  
 public class HelloVaadin extends Application {  
   @Override  
   public void init() {  
     Window mainWindow = new Window("HelloVaadin");  
     Label label = new Label("Hello Vaadin user");  
     mainWindow.addComponent(label);  
     setMainWindow(mainWindow);  
   }  
 }  

Step four
--------

Edit you web.xml file under webapp/web.xml as following

 <!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 version="2.5" 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_2_5.xsd]">  
   <display-name>HelloVaadin</display-name>  
   <context-param>  
     <param-name>productionMode</param-name><param-value>false</param-value><description>Vaadin production mode</description>  
   </context-param>  
   <servlet>  
     <servlet-name>HelloVaadin</servlet-name>  
     <servlet-class>com.vaadin.terminal.gwt.server.ApplicationServlet</servlet-class>  
     <init-param>  
       <param-name>application</param-name>  
                <param-value>com.sample.vaadin.HelloVaadin</param-value>  
                <description>Vaadin application class to start</description>  
     </init-param>  
   </servlet>  
   <servlet-mapping>  
     <servlet-name>HelloVaadin</servlet-name>  
     <url-pattern>/*</url-pattern>  
   </servlet-mapping>  
 </web-app>
