Can't find any documentation on the MDB deployment... Heres is my configuration: @MessageDriven(activationConfig = { @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"), @ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/A") }) Here is the problem... Reason: java.lang.RuntimeException: You did not specify a @Resource.mappedName ) on javax.jms.Queue com.valtech.servicebancaire.BanqueBean.emailQueue and ther is no binding for that enc name in XML what is this mappedName ????
