first example, i use maven2

[Lucas Nussbaum]

Hello, I'm reading the book: "practical apache struts2 web 2.0 projects" by Ian Roughley. I have questions.
1) I do not know if Maven2 replaces an application server. Otherwise, what do I need?
2) the following command to build the directory structure does not give the results hoped for.

mvn archetype:create
-DgroupId=com.fdar.apress.s2
-DartifactId=app
-DarchetypeGroupId=org.apache.struts
-DarchetypeArtifactId=struts2-archetype-starter
-DarchetypeVersion=2.0.9-SNAPSHOT
-DremoteRepositories=http://people.apache.org/maven-snapshot-repository

mvn archetype:create -DgroupId=com.fdar.apress.s2 -DartifactId=app -DarchetypeGroupId=org.apache.struts -DarchetypeArtifactId=struts2-archetype-starter -DarchetypeVersion=2.0.9-SNAPSHOT -DremoteRepositories=http://people.apache.org/maven-snapshot-repository

Also, I can not start the jetty server by : "mvn jetty:run "
(I just installed maven2, on ubuntu)

mvn jetty:run

Maven2 is a build tool. You will need an application server. What does the book recommend?

2) the following command to build the directory structure does not give the results hoped for.

What structure did you hope for? Are you familiar with the way Maven works?

Also, I can not start the jetty server by : "mvn jetty:run "

Did you install Jetty?
