Deploying a Jersey webapp on Jboss AS 7
问题 Currently running some webapps on Jboss AS 4/5 and I am testing migration to jboss7. When I try to deploy a jersey based webapp on JBoss AS 7 (full profile with standalone-preview config file), I get: org.jboss.as.server.deployment.DeploymentUnitProcessingException: Only one JAX-RS Application Class allowed. I've done a bit of hunting around on it and found that RestEasy is the default JAX-RS implementation embedded into Application Server. Posts like http://community.jboss.org/message/579996
