Application was working fine with Glassfish 3+ but on migrating it to WildFly 8 it is throwing following error while running. Application is shown in deployments, and postgressql jar too is existing in deployments. Java 6 is used.

JBAS014671: Failed services => { jboss.deployment.unit.\"mywar.file.SNAPSHOT.war\".INSTALL" => "org.jboss.msc.service.StartException in service jboss.deployment.unit.\"mywar.file.SNAPSHOT.war\".INSTALL" JBAS018733: Failed to process phase INSTALL of deployment \"mywar.file.SNAPSHOT.war\" Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS014544: No EJB found with interface of type "my.services.UserFacade" for binding my.package.RefFacade/userService"},

JBAS014771: Services with missing/ unavailable dependencies => ["jboss.deployment.unit.\"mywar.file.SNAPSHOT.war\".weld.weldClassIntrospector is missing  ["jboss.deployment.unit.\"mywar.file.SNAPSHOT.war\".beanmanager]"]}

What can be the issue and how to fix it?
