Yes, all of our demos and archetypes include a profile for building an AS7-deployable .war file (the profile also works for EAP6 and OpenShift). You can just build like this:

    % mvn package -Pjboss7

If you're rolling your own pom.xml (or not using Maven for your project), the best way to glean this information would be to create a project from one of our archetypes, then use `mvn dependency:tree -Pjboss7` to see what's marked as "provided" rather than "compile."

Having said all this, we've been brainstorming better ways to organize all of this: the demos, the archetypes, and the dependency scopes for different deployment scenarios. So far, we have more questions than answers. If you (or anyone else) has ideas, let's discuss it on the mailing list!

Correct, this will happen for each .jar that has an ErraiApp.properties. The cause is that Mike recently factored out JBoss 7 support code into its own module that you'll have to depend on when deploying to AS7/EAP6/OpenShift. The module is org.jboss.errai:errai-jboss-as-support:3.0-SNAPSHOT.

You'll probably find that dynamic marshalling doesn't work properly when you get those errors at deployment time.

Our pleasure!
