Galera, é o seguinte… Estou precisando desenvolver um projeto com JPA + Hibernate + JSF 2 + JBoss AS 7.0.1, acontece que nunca trabalhei com o JBoss e estou apanhando pacas, já procurei na net a torto e a direito a minha dúvida aqui mas não consegui resolver meu problema. Estou tentando desenvolver minha aplicação web quase que da mesma forma como eu faria com o Tomcat 7, e talvez esse seja o meu erro.
Bem, meu problema é o seguinte… meu projeto não faz o deploy nem “cum nojo” no JBoss, o a mensagem de erro é a seguinte:
02:01:12,878 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC00001: Failed to start service jboss.deployment.unit."MeuProjeto.war".INSTALL: org.jboss.msc.service.StartException in service jboss.deployment.unit."MeuProjeto.war".INSTALL: Failed to process phase INSTALL of deployment "MeuProjeto.war"
