Newbie: M2Eclipse and WTP/JBoss Tools

[gifor]

Hi,
I have to manage a JEE project with Eclipse and Maven. We’d like to use M2Eclise and WTP (or JBoss Tools) to deploy an EAR (3 module: JAR, WAR and EAR) in JBoss running inside the IDE, i.e. our development environment.
We already have a Maven parent project with 3 related child project (JAR, WAR, EAR).
Has someone tips on how to manage this configuration with an application server running inside Eclipse (for debugging)? Do you have guideline/docs about how to configure maven and eclipse to allow these tools integration?

Thank you in advance for any suggestions…
