      Hello,

       

      I'm new with Errai. I'm using JBoss 7.1.0.Final, Maven 3.0, Eclipse Indigo. I build a simple project using the maven command

       

      mvn archetype:generate -DarchetypeGroupId=org.jboss.errai.archetypes -DarchetypeArtifactId=cdi-quickstart -DarchetypeVersion=2.1.0.CR1 -DarchetypeRepository=https://repository.jboss.org/nexus/content/groups/public/

       

      so I obtained a maven project. I imported it in Eclipse and code some basic stuff (I was trying to reproduce one of the first examples in the Errai reference guide). Then I try to "run as a web application" by Eclipse and i got this error (I cut the first part because of its size):

      I attached my pom.xml and the maven project's src directory, so you can try to reproduce the problem. I think Errai is a very cool framework, I want to learn more about it. This error is blocking me 'cause I lack profiencies in JBoss, Maven and Errai of course. I really appreciate an help. TIA.
