Create a simple maven project
$ mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart
It works in interactive mode, so you will be asked to type groupId, atifactId and so on.
Here how to create a webapp template from the maven archetype plugin in not interactive mode.
$ mvn archetype:generate -DgroupId=org.enricogiurin.poc -DartifactId=maven-usage -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
https://maven.apache.org/archetype/maven-archetype-bundles/maven-archetype-quickstart/

http://maven.apache.org/guides/mini/guide-building-for-different-environments.html
http://maven.apache.org/plugins/maven-resources-plugin/examples/copy-resources.html
To make compatible with java 8, add this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>

Soup with vegetables
So, let's start!
- Cut the potatoes, carrots, green beans, pepper, onion in small pieces, not so small though.
- Put these ingredients in a pot and fill it with the water.
- Light the fire and wait till the water in the pot start to boil.
- Once it's boiling reduce the level of firing to minimum and let it boil for other 60 minutes; really this is important, the level of firing should be very low, you should observe the level of water just boiling a bit.
- Add the potatoes in the pot.
- Add two spoons of oil of olive and a bit of salt.
- Let it boil, always with low fire, for about 25 minutes.
- Add the tomato sauce and half of dado knorr
- Let it boil for the last 5 minutes.
I learned how to prepare it today in the soup session with my friend Cristian, I hope to have not forgotten some steps so I won't consider myself responsible of the success of the soup ;-)

Building Reactive Apps @ Jug Lausanne
Yesterday I've participated at the meeting @ JUG Lausanne, where there was a presentation with the title "Building Reactive Apps" kept by James Ward.
In the room there were about 40 persons and the speech was kept in English.
After having talked about the reactive manifesto , the speaker shortly introduced the principles of reactive programming
Has followed a demo of how to build a reactive application with the play framework, where he showed the usage of Future classes. Other topics were related websocket, actors in AKKA, scala and so on.
I think I'll give a try to these new technologies.

NoClassDefFoundError in Jboss with maven EJB plugin when using SNAPSHOT dependencies
Context: Jboss 5.1.0, maven 2.x, snapshot dependencies.
Problem: I got this exception after deployed my ear in jboss 5.1.
EAR name: myEAR.ear
ejb component: services.jar
Jboss classloader cannot find the myPackage/MyInterface.class when this is a SNAPSHOT dependency of my services.jar.
Solution: Correct configuration of the maven ejb plugin.
You need to set to false the useUniqueVersion attribute.
