Well, I am using EntityManager in my application. Hiberanate is using other application which i am connecting to. but i don't know where is this exception is coming from. but i can see this exception on console after completion of process flow.
Below is my MDB
@MessageDriven(name = "ImportXMLMDB", activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
@ActivationConfigProperty(propertyName = "destination", propertyValue = "importXMLQueue"),
@ActivationConfigProperty(propertyName = "sendUndeliverableMsgsToDMQ", propertyValue = "true")})
@ActivationConfigProperty(propertyName = "endpointExceptionRedeliveryAttempts", propertyValue = "1") })
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public class ImportXMLMDB implements MessageListener {
private final static Logger log = LoggerFactory.getLogger(ImportXMLMDB.class);
@EJB
private ProcessXMLLocal processXMLLocal;
// @Resource
// private SessionContext context;
@PersistenceContext(unitName = "AOMAPersistence")
private EntityManager em;
/**
* This method will call for each message to process.
*/
public void onMessage(Message message) {
try {
em = DatabaseUtil.getEntityManager();
if (message instanceof MapMessage) {
log.info("i am calling MapMessage");
MapMessage xmlMapMsg = (MapMessage) message;
byte[] xmlMsg = xmlMapMsg.getBytes("xmlMapString");
processXMLLocal.processXML(xmlMsg, em);
log.info("processing of XML successful");
}else if(message instanceof TextMessage) {
log.info("i am calling TextMessage");
TextMessage xmlTxtMsg = (TextMessage) message;
String xmlMsg = xmlTxtMsg.getText();
byte[] xmlMsgByte = xmlMsg.getBytes();
processXMLLocal.processXML(xmlMsgByte, em);
log.info("processing of XML successful");
}
} catch (Throwable e) {
e.printStackTrace();
// context.setRollbackOnly();
log.error("Exception while getting text from message: {}", e.getMessage());
// throw new RuntimeException(e);
}finally {
em.close();
log.info("finally block of onMessage - ImportXMLMDB");
}
