I too get this error. My environment is identical to littlewing's. To verify, I downloaded a clean copy of Seam 2.0 Beta, changed to the examples/booking directory and tried "ant testexample". The stacktrace is also identical to littlewing's and refers to two missing rars: jboss.jca:name='jms-ra.rar',service=RARDeployment -> ** NOT FOUND ** jboss.jca:name='jboss-local-jdbc.rar',service=RARDeployment -> ** NOT FOUND ** I thought I could bypass it by overriding the startJbossEmbeddedIfNecessary method in my test case but that gives me a NoSuchMethodError for a Drools class: Caused by: java.lang.NoSuchMethodError: org.drools.RuleBase.newStatefulSession(Z)Lorg/drools/StatefulSession; at org.jboss.seam.security.RuleBasedIdentity.initSecurityContext(RuleBasedIdentity.java:65) at org.jboss.seam.security.RuleBasedIdentity.create(RuleBasedIdentity.java:53) I figured I should wait until the Booking example is working before I try anything else.
