Not sure this should be here, but thought I should document how I got started on a RSF project.
(I wouldn't even assume that this project will ever get anywhere, but documenting a getting started with RSF could be helpful...)

World is my "dream" project of getting a decent Email Calendar Task-List thing started. Some would call it a PIM, some others would call it insane and would query why I'm even bothering however, I shall begin and no doubt promptly forget about this when term and thus work starts in earnest... :p

OK for starters... Lets take a look at what the basic pom.xml should be.

First off I assume I'll be needing RSFHibernate3 and some other things so I guess I'll need a pom thus:

Not entirely sure that's minimal nor quite what the parent pom is about. I expect I don't need that.

Now we want a datamodel, and we don't want to be messing around too much with it, so lets try to get a maven-hibernate3 plugin working.

I'll first make the project multiproject by moving the webapp part out and adding a dependence on world-datamodel. then I'll create a datamodel project.

''Again I'm not sure whether this is minimal...''

Now in src/main/resources/ create a hibernate.cfg.xml and mappings.hbm.xml:

hibernate.cfg.xml
{{{
<?xml version="1.0"?>
<!DOCTYPE hibernate-configuration PUBLIC
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <mapping resource="mappings.hbm.xml"/>
        </session-factory>
</hibernate-configuration>
}}}

mappings.hbm.xml should be of the type of hibernate-mapping 

Now the rather confusing thing is: hbm2java relies the mappings files being in target/classes for it to see them
This means that the hibernate3:hbm2java goal will run in the process-resources phase rather than generate-sources. (This confused me for some time.)

Now if you've got it all correct mvn install should compile and create a working datamodel for you. Wooness...
