This is a guide document that how you can setting up JMS Queue and JMX on JBoss AS 7.1.1.Final or EAP6. In EAP5, server port for JMS used 1099, but EAP6 doesn't use that port any longer. This also explains about JBoss JMX to monitor Java heap and JMX via MBean. If you want to get more information or open source, please email

메시지1
메시지2
- Point-to-Point 모델에서는 Sender에 의해 발생된 메시지가 Queue라는 채널에 전달되고, 이 메시지는
Queue에 의해 자동으로 Receiver에 전달
- Publisher/Subscriber 모델과 다른 점은 Queue에 전달된 하나의 메시지는 오직 하나의 Receiver에만 전달되
고 다수의 Receiver 에 전달되지 않음
- Sender에 의해 Queue에 전달된 메시지1은 Queue에 의해 Receiver1에 전달되고, Sender에 의해 전달된 메
시지2는 Queue에 의해 Receiver2에 전달
- Publisher/Subscriber 모델처럼 동일한 메시지가 서로 다른 Receiver에 전달되지 않음

Topic
메시지1
메시지2
- Publisher/Subscriber 모델에서는 Publisher가 하나의 메시지를 다수의 Subscriber(Consumer)에게
Topic 이라는 채널을 통하여 전달
- 모든 Subscriber는 Publisher가 Topic에 보낸 하나의 메시지의 사본을 전달 받게 되며, 이와 같은 메시
지 전달은 Topic에 의해 자동으로 Subscriber에 전달
- Publisher 에 의해 전달된 메시지1은 동시에 Subscriber1, Subscriber2 에 전달되며, Publisher에 의해
전달된 2번째 메시지인 메시지2 도 Subscriber1, Subscriber2에 전달

4. JBoss JMS 핵심 기능
JMS 1.1 스펙 준수 및 JBoss AS의 런타임 라이브러리로 사용.
성능, 신뢰성, 안정성 및 낮은 응답시간 등에 초점을 둠.
SOA의 초기 단계인 JBoss ESB의 핵심 모듈로서 사용

8. JMS 사용자 생성
JMS 접근 사용자 생성
C:Javajboss-eap-6.1bin>add-user.bat
JAVA_HOME is not set. Unexpected results may occur.
Set JAVA_HOME to the directory of your local JDK to avoid this message.
What type of user do you wish to add?
a) Management User (mgmt-users.properties)
b) Application User (application-users.properties)
(a): b
Enter the details of the new user to add.
Realm (ApplicationRealm) :
Username (testuser) : ienvyou
Password : !test123
Re-enter Password : !test123
What roles do you want this user to belong to? (Please enter a comma separated list, or leave blank for
none)[ ]: testrole
About to add user 'ienvyou' for realm 'ApplicationRealm'
Is this correct yes/no? yes
Added user 'ienvyou' to file 'C:Javajboss-eap-6.1standaloneconfigurationapplication-users.properties'
Added user 'ienvyou' to file 'C:Javajboss-eap-6.1domainconfigurationapplication-users.properties'
Added user 'ienvyou' with roles testrole to file 'C:Javajboss-eap6.1standaloneconfigurationapplication-roles.properties'
Added user 'ienvyou' with roles testrole to file 'C:Javajboss-eap-6.1domainconfigurationapplicationroles.properties'
Is this new user going to be used for one AS process to connect to another AS process?
e.g. for a slave host controller connecting to the master or for a Remoting connection for server to server
EJB calls.
yes/no?

try {

properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
properties.put(Context.PROVIDER_URL, "remote://localhost:4447");

Context ctx = new InitialContext(properties);
ConnectionFactory cf = (ConnectionFactory) ic.lookup("jms/RemoteConnectionFactory");
Queue queue = (Queue) ic.lookup(destinationName);
System.out.println("Queue " + destinationName + " exists");
Connection connection = cf.createConnection("ienvyou", "!test123");
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
MessageProducer sender = session.createProducer(queue);
sender.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
TextMessage message = session.createTextMessage("Hello!");
sender.send(message);
System.out.println("The message was successfully sent to the " + queue.getQueueName() + " queue");

12. With JMX(Java Management Extension)
JMX를 이용할 경우 소프트웨어 관리 포인트를 한 곳으로 집중할 수 있다는 장점이 발생.(JSR-255)
• 모든 리소스는 MBean을 사용하여 관리.
• JMX Agent (or group of agents)상의 모든 MBean은 하나의 관리 콘솔에서 모두 처리
