Hi It works now!! In hibernate.cfg.xml, I changed: | <property name="connection.datasource">ArmadaSeamProjectDatasource</property> | to: | <property name="connection.datasource">java:/ArmadaSeamProjectDatasource</property> | And for injected Seam-managed hibernate sessions, names should be the same in components.xml and Java code, for example: | <persistence:managed-hibernate-session name="hibernateSession" auto-create="true"/> | | @In | private Session hibernateSession; | Thank you all and special thanks for Mr. Pete.Muir, you showed an exceptional patience. :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128150#...
