User development, A new message was posted in the thread "[6.0.0M2] SessionContext "mapped-name is required"": http://community.jboss.org/message/528240#528240 Author : Guy Coleman Profile : http://community.jboss.org/people/gcoleman Message: -------------------------------------------------------------- Found it.
