Running an embeded Apache Tomcat
Simply use mvn tomcat*:run to run your Apache Maven war project.
No Apache Tomcat to install locally. Maven will download all necessary
jars to run an embeded Tomcat.
In Maven3 multi modules project, reactors projects automatically
added to the webapp classloader : no need to install all jars
dependencies.
Easy developpement of webapp : no need of restart/install war when
modifying jsp/css etc...
Debug in your ide with mvnDebug.

Deployment in Apache Tomcat
Deploy your Apache Maven project in a running Apache Tomcat
instance.
Attach the deploy goal to the deploy phase in a profile and your build
war will be deploy in a running Tomcat instance.
Simple : mvn deploy -Ptdeploy
Run the Maven lifecycle (build your war, deploy it to your Repo Man
and deploy it to your Tomcat instance)

Executable jar/war
Mojo goal to build a standalone jar to run your war.
Jar will include your webapps and all necessary Tomcat jars.
Cli : mvn tomcat7:exec-war produces a jar my-project-exec-war.jar
Simply your project : jar -jar my-project-exec-war.jar
Come with some default setup: http port, default server.xml
But optionnal cli options : -httpPort -ajpPort etc.. (RTFM :-) )

Maven archetype
There is now an archetype :
mvn archetype:generate
-DarchetypeGroupId=org.apache.tomcat.maven
-DarchetypeArtifactId=tomcat-maven-archetype
-DarchetypeVersion=2.0-SNAPSHOT
Generate a standard multi modules Maven project :
* basic-api (service interface)
* basic-api-impl (service default impl).
* basic-webapp (our webapp module)
* basic-webapp-exec (module to generated executable war)
* basic-webapp-it (module to run selenium tests with generated war)
