My first web program with maven

Maven installation steps:

1.  Install jdk 1.7 and set the class path.
2. Unzip the to  apache-maven-3.0.4-bin.zip the directory you wish to install maven. The sub directory  apache-maven-3.0.4  will be created from archive in your choosen directory( C:\Program Files\Apache Software Foundation\apache-maven-3.0.4).
3. Add %JAVA_HOME% variable in your user variables with the value e.g. C:\Program Files\Java\jdk1.7 .
4. Add  C:\Program Files\Apache Software Foundation\apache-maven-3.0.4\bin in you "Path" environment variable.
5. Open a new command prompt and run mvn -v to verify that it is correctly installed

Steps to create build and run a maven project:

1. Create a project directory where you wants to create the maven project.
2. Go to that directory via command prompt.
3. Create project using the command "mvn archetype:generate -DarchetypeArtifactId=maven-archetype-webapp -DgroupId=org.yarlithub.yschool -DartifactId=yschool-mini-vanaja".
4. Then go to your project directory (yschool-mini-vanaja).
5. Then run the command with "mvn compile".
6. This will create a folder target with compile classes.
7. To run our project we need a web server. For testing purpose we can use jetty. So we need to add a jetty plug-in to maven pom.xml file. Plug-in should be added under build tag.

<project ...>

<dependencies>

<.../

</dependencies>

<build>

<finalName>yschool</finalName>

<plugins>

<plugin>

<groupId>org.mortbay.jetty</groupId>

<artifactId>maven-jetty-plugin</artifactId>

<version>6.1.10</version>

<!--<configuration>-->

<!--<scanIntervalSeconds>10</scanIntervalSeconds>-->

<!--<stopKey>stop</stopKey>-->

<!--<stopPort>9999</stopPort>-->

<!--</configuration>-->

<executions>

<execution>

<id>start-jetty</id>

<phase>deploy</phase>

<goals>

<goal>run</goal>

</goals>

<configuration>

<scanIntervalSeconds>0</scanIntervalSeconds>

<daemon>true</daemon>

</configuration>

</execution>

</executions>

</plugin>

</plugins> </build> </project>


9.    After adding the plug-in run the command  "mvn install jetty:run".
10.  Now Jetty will be start and project will be deployed there.
11.  Now go to your browser and type http://localhost:8080/<project-name>
12.  There will be your page displaying.
