I was written a simple MessageListener(MDB) it is working fine.How to handle runtime exceptions in this.
[例: このリスナーを正しいキュー名ではなく「XXXX」のような間違ったキュー名でデプロイしようとすると、例外が表示され、さらにデプロイの失敗も発生します。]
したがって、このタイプの例外を回避する方法は、利用可能な注釈があります。
そして、以下の内部で処理しようとしましたClass(ORANGE_QUEUE_MDB)。しかし、コントロールは内側に来ていません。このタイプのエラーを解決する方法を教えてください。
@MessageDriven(name="WEBSPHERE_MDB",
activationConfig = {
@ActivationConfigProperty(propertyName="messagingType",propertyValue="javax.jms.MessageListener"),
@ActivationConfigProperty(propertyName = "destinationType",propertyValue = "javax.jms.Queue"),
@ActivationConfigProperty(propertyName = "destination", propertyValue = "ORANGE.QUEUE"),
@ActivationConfigProperty(propertyName = "useJNDI", propertyValue = "false"),
@ActivationConfigProperty(propertyName = "channel", propertyValue = "SYSTEM.DEF.CONN"),
@ActivationConfigProperty(propertyName = "hostName", propertyValue = "192.168.22.29"),
@ActivationConfigProperty(propertyName = "queueManager", propertyValue = "manager"),
@ActivationConfigProperty(propertyName = "port", propertyValue = "1414"),
@ActivationConfigProperty(propertyName = "transportType", propertyValue = "CLIENT"),
@ActivationConfigProperty(propertyName = "username", propertyValue = "mqm"),
@ActivationConfigProperty(propertyName = "password", propertyValue = "password")
},
mappedName = "ORANGE.QUEUE",
messageListenerInterface = MessageListener.class)
@ResourceAdapter(value = "wmq.jmsra.rar")
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
@ApplicationException(rollback = true)
public class ORANGE_QUEUE_MDB extends RuntimeException implements MessageListener
{
public void onMessage(Message message) {
try{
TextMessage textMessage=(TextMessage) message;
}
catch(Exception e)
{
e.printStackTrace();
}
Jbossでリスナーの上に（間違ったキュー名で）デプロイすると、例外の下に表示されます例外は以下のようです：
