I am trying to send a JMS message to remote ActiveMQ Artemis queue that is embedded in JBoss EAP 7.2. I have defined the following in standalone-full.xml:

Below is my client program:

initialProperties.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory");
initialProperties.put(InitialContext.PROVIDER_URL, "tcp://127.0.0.1:61616");

factory = (QueueConnectionFactory) context.lookup("java:/jms/remoteIM");
destination = (Queue) context.lookup("java:global/remoteContext/ImportantMessages");
connection = factory.createConnection();
session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
producer = session.createProducer(destination);
EventMessage eventMessage = new EventMessage("1", "Message from FirstClient");
ObjectMessage objectMessage = session.createObjectMessage();
objectMessage.setObject(eventMessage);
connection.start();
producer.send(objectMessage);
System.out.println(this.getClass().getName() + "has sent a message : " + eventMessage);
} catch (NamingException e) {
e.printStackTrace();
} catch (JMSException e) {
e.printStackTrace();
} finally {
if (context != null) {
try {
context.close();
} catch (NamingException ex) {
ex.printStackTrace();
}
}
if (connection != null) {
try {
connection.close();
} catch (JMSException ex) {
ex.printStackTrace();
}
}
}
}
I am getting the below exception:

Can anyone suggest me what wrong I am doing here?
回答1:
In order to send a JMS message to remote ActiveMQ Artemis queue that is embedded in JBoss EAP you can use the default standalone-full.xml. You don't need to set up a remote connector, pooled connection factory, or remote binding. You simply need to lookup jms/RemoteConnectionFactory from your client using JBoss EAP JNDI context. To be clear, when ActiveMQ Artemis is embedded in JBoss EAP remote clients use the JBoss EAP JNDI context not the ActiveMQ Artemis JNDI context since EAP itself is in charge of all JNDI operations.
Your client is using the ActiveMQ Artemis JNDI context:
initialProperties.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory");
initialProperties.put(InitialContext.PROVIDER_URL, "tcp://127.0.0.1:61616");
This is incorrect. You should be using this instead:
initialProperties.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");
initialProperties.put(InitialContext.PROVIDER_URL, "http-remoting://127.0.0.1:8080");
Note: You could also use org.jboss.naming.remote.client.InitialContextFactory here because that class is also shipped with JBoss EAP 7.2. However, this class is really included for backwards compatibility with legacy clients.
Then your client is trying to lookup the pooled-connection-factory you configured in standalone-full.xml:
factory = (QueueConnectionFactory) context.lookup("java:/jms/remoteIM");
This is also incorrect. A pooled-connection-factory can only be used by clients running in the same JVM as JBoss EAP (e.g. an MDB which needs to send a message). You can't simply look it up from a remote client and expect to get pooling. That's not how it works. You should be doing this instead:
factory = (QueueConnectionFactory) context.lookup("jms/RemoteConnectionFactory");
This will use the default connection-factory in standalone-full.xml named RemoteConnectionFactory.
Then you're looking up a queue which isn't even defined in the messaging subsystem (i.e. java:global/remoteContext/ImportantMessages). You've apparently configured it in an external-context for some reason. This is wrong for EAP. You should define this in your standalone-full.xml:
<jms-queue name="ImportantMessages" entries="java:jboss/exported/ImportantMessages"/>
And then use this in your client:
destination = (Queue) context.lookup("ImportantMessages");
Ultimately, this is what your messaging subsystem in standalone-full.xml should look like:
<subsystem xmlns="urn:jboss:domain:messaging-activemq:4.0">
<server name="default">
<journal pool-files="10"/>
<security-setting name="#">
<role name="guest" send="true" consume="true" create-non-durable-queue="true" delete-non-durable-queue="true"/>
</security-setting>
<address-setting name="#" dead-letter-address="jms.queue.DLQ" expiry-address="jms.queue.ExpiryQueue" max-size-bytes="10485760" page-size-bytes="2097152" message-counter-history-day-limit="10"/>
<http-connector name="http-connector" socket-binding="http" endpoint="http-acceptor"/>
<http-connector name="http-connector-throughput" socket-binding="http" endpoint="http-acceptor-throughput">
<param name="batch-delay" value="50"/>
</http-connector>
<in-vm-connector name="in-vm" server-id="0">
<param name="buffer-pooling" value="false"/>
</in-vm-connector>
<http-acceptor name="http-acceptor" http-listener="default"/>
<http-acceptor name="http-acceptor-throughput" http-listener="default">
<param name="batch-delay" value="50"/>
<param name="direct-deliver" value="false"/>
</http-acceptor>
<in-vm-acceptor name="in-vm" server-id="0">
<param name="buffer-pooling" value="false"/>
</in-vm-acceptor>
<jms-queue name="ImportantMessages" entries="java:jboss/exported/ImportantMessages"/>
<jms-queue name="ExpiryQueue" entries="java:/jms/queue/ExpiryQueue"/>
<jms-queue name="DLQ" entries="java:/jms/queue/DLQ"/>
<connection-factory name="InVmConnectionFactory" entries="java:/ConnectionFactory" connectors="in-vm"/>
<connection-factory name="RemoteConnectionFactory" entries="java:jboss/exported/jms/RemoteConnectionFactory" connectors="http-connector"/>
<pooled-connection-factory name="activemq-ra" entries="java:/JmsXA java:jboss/DefaultJMSConnectionFactory" connectors="in-vm" transaction="xa"/>
</server>
</subsystem>
You don't need the external-context you've configured.
Lastly, this is what your client should ultimately look like:
public void sendObjectMessage() {
Properties initialProperties = new Properties();
initialProperties.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");
initialProperties.put(InitialContext.PROVIDER_URL, "http-remoting://127.0.0.1:8080");
try {
context = new InitialContext(initialProperties);
factory = (QueueConnectionFactory) context.lookup("jms/RemoteConnectionFactory");
destination = (Queue) context.lookup("ImportantMessages");
connection = factory.createConnection();
session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
producer = session.createProducer(destination);
EventMessage eventMessage = new EventMessage("1", "Message from FirstClient");
ObjectMessage objectMessage = session.createObjectMessage();
objectMessage.setObject(eventMessage);
connection.start();
producer.send(objectMessage);
System.out.println(this.getClass().getName() + "has sent a message : " + eventMessage);
} catch (NamingException e) {
e.printStackTrace();
} catch (JMSException e) {
e.printStackTrace();
} finally {
if (context != null) {
try {
context.close();
} catch (NamingException ex) {
ex.printStackTrace();
}
}
if (connection != null) {
try {
connection.close();
} catch (JMSException ex) {
ex.printStackTrace();
}
}
}
}
JBoss EAP has a bunch of "quickstart" applications available to demonstrate how to use its features. Here is the JMS "Hello World" quickstart which you might find useful for reference.
If you're building your client application with Maven then this is the dependency you should be using:
<dependency>
<groupId>org.jboss.eap</groupId>
<artifactId>wildfly-jms-client-bom</artifactId>
<type>pom</type>
</dependency>
Also, keep in mind that ActiveMQ Artemis embedded in JBoss EAP 7.2 is secured by default so you will either need to disable security in the messaging subsystem (e.g. using <security enabled="false"/>) or add a user to the ApplicationRealm (e.g. via the bin/add-user.sh script) and pass the proper credentials when you create your connection.
