To view the discussion, visit: http://community.jboss.org/message/571690#571690 -------------------------------------------------------------- I did this to resolve my requirement: Implement an interceptor on my service.  It uses the AttributePersistenceService directly to save attributes.  Implement the 'start' lifecycle method to load attributes from the AttributePersistenceService. {code} @Depends("jboss:service=AttributePersistenceService") private AttributePersistenceServiceMBean attributePersistenceService; @AroundInvoke public Object intercept(InvocationContext context) throws Exception { Object result = context.proceed(); if(context.getMethod().getName().startsWith("set")) { saveAttributes(); } return result; } public void start() throws Exception { loadAttributes(); } private void saveAttributes() throws Exception { AttributePersistenceManager manager = getAttributePersistenceManager(); if(manager != null) { AttributeList attrs = new AttributeList(); attrs.add(new Attribute("syncInterval", syncInterval)); LOGGER.debug("saving attributes: {}", attrs); manager.store(ATTRIBUTE_KEY, attrs); } } private void loadAttributes() throws Exception { AttributePersistenceManager manager = getAttributePersistenceManager(); if(manager != null) { AttributeList attrs = manager.load(ATTRIBUTE_KEY); for(Attribute attribute: attrs.asList()) { if("syncInterval".equals(attribute.getName())) { this.syncInterval = ((Long)attribute.getValue()).longValue(); } } } } private AttributePersistenceManager getAttributePersistenceManager() { AttributePersistenceManager result = null; if(attributePersistenceService != null) { result =  attributePersistenceService.apmCreate(); } return result; } @AroundInvoke public Object intercept(InvocationContext context) throws Exception { Object result = context.proceed(); if(context.getMethod().getName().startsWith("set")) { saveAttributes(); } return result; } public void start() throws Exception { loadAttributes(); } private void saveAttributes() throws Exception { AttributePersistenceManager manager = getAttributePersistenceManager(); if(manager != null) { AttributeList attrs = new AttributeList(); attrs.add(new Attribute("syncInterval", syncInterval)); LOGGER.debug("saving attributes: {}", attrs); manager.store(ATTRIBUTE_KEY, attrs); } } private void loadAttributes() throws Exception { AttributePersistenceManager manager = getAttributePersistenceManager(); if(manager != null) { AttributeList attrs = manager.load(ATTRIBUTE_KEY); for(Attribute attribute: attrs.asList()) { if("syncInterval".equals(attribute.getName())) { this.syncInterval = ((Long)attribute.getValue()).longValue(); } } } } private AttributePersistenceManager getAttributePersistenceManager() { AttributePersistenceManager result = null; if(attributePersistenceService != null) { result =  attributePersistenceService.apmCreate(); } return result; } {code} -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/571690#571690] Start a new discussion in EJB3 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
