When I create a Maven project using artifact ID
jboss-javaee6-webapp-archetype version
7.1.3.CR8, there are a bunch code are already crated for you. My personal habit is whenever a project is first created, I will make a deploy to ensure my server is up and running properly. Somehow I got the following message complaining something was went wrong:

I was wondering since when I got such an import.sql get invoked in my code? I was searching in the whole project code and I didn't find any. Later I found out
this blog, Hibernate has a mechanism to load SQL script on startup.
You can execute an SQL script during the SessionFactory creation right after the database schema generation to import data in a fresh database. You just need to add a file named import.sql in your classpath root and set either create or create-dropas your hibernate.hbm2ddl.auto property.
Got it, that file did really exists in the classpath. To make my life simple, I would just rename import.sql to other name.
