I am newbie to activemq.I have downloaded latest activemq 5.8 and run the server.I have created queue and sending sample messages using following code:
// URL of the JMS server. DEFAULT_BROKER_URL will just mean
// that JMS server is on localhost
private static String url = ActiveMQConnection.DEFAULT_BROKER_URL;
// Name of the queue we will be sending messages to
private static String subject = "TESTQUEUE";
public static void main(String[] args) throws JMSException {
// Getting JMS connection from the server and starting it
ConnectionFactory connectionFactory =
new ActiveMQConnectionFactory(url);
Connection connection = connectionFactory.createConnection();
connection.start();
// JMS messages are sent and received using a Session. We will
// create here a non-transactional session object. If you want
// to use transactions you should set the first parameter to 'true'
Session session = connection.createSession(false,
Session.AUTO_ACKNOWLEDGE);
// Destination represents here our queue 'TESTQUEUE' on the
// JMS server. You don't have to do anything special on the
// server to create it, it will be created automatically.
Destination destination = session.createQueue(subject);
// MessageProducer is used for sending messages (as opposed
// to MessageConsumer which is used for receiving them)
MessageProducer producer = session.createProducer(destination);
// We will send a small text message saying 'Hello' in Japanese
TextMessage message = session.createTextMessage("こんにちは");
// Here we are sending the message!
producer.send(message);
System.out.println("Sent message '" + message.getText() + "'");
connection.close();
}
I have run above code and queue created successfully.Now i want to restrict user access in activemq server.I changed the createConnnection method as below
Connection connection = connectionFactory.createConnection("test","test");
Now if i run changed code messages sending to queue successfully.but test user is not there in activemq even connection established.How to restrict this user?

In the above file is activemq.xml.Now i want to access queue only certain users only.
How to restrict users in actviemq? what am i need change above activemq.xml file?
See ActiveMQ doc: http://activemq.apache.org/security.html
In activemq.xml :
Define queues you want to create in "destinations" section .
You can control privileges by defining groups in the "users" section.
In the "authorizationEntries" section, you can define what groups are allowed to read, write and admin a queue.
Framgent of activemq.xml:
<destinations>
<queue physicalName="DEMOQUEUE01" />
<queue physicalName="DEMOQUEUE02" />
<queue physicalName="DEMOQUEUE03" />
</destinations>

I created a one and only broker in activemq and I am using the following code to produce and consume messages. I took this code from here.
public boolean runExample() throws Exception {
Connection connection = null;
InitialContext initialContext = null;
try {
Properties properties = new Properties();
properties.put("java.naming.factory.initial", "org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory");
properties.put("connectionFactory.ConnectionFactory", "tcp://localhost:61616");
properties.put("queue.queue/exampleQueue", "exampleQueue");
initialContext = new InitialContext(properties);
Queue queue = (Queue) initialContext.lookup("queue/exampleQueue");
ConnectionFactory connectionFactory = (ConnectionFactory) initialContext.lookup("ConnectionFactory");
connection = connectionFactory.createConnection("admin", "admin");//brokerone
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
MessageProducer producer = session.createProducer(queue);
TextMessage message = session.createTextMessage("This is a text message");
System.out.println("Sent message: " + message.getText());
producer.send(message);
MessageConsumer messageConsumer = session.createConsumer(queue);
connection.start();
TextMessage messageReceived = (TextMessage) messageConsumer.receive(5000);
System.out.println("Received message: " + messageReceived.getText());
return true;
} finally {
if (initialContext != null) {
initialContext.close();
}
if (connection != null) {
connection.close();
}
}
}
Now, while creating connection if I put any random string for password in connectionFactory.createConnection method then it still creates connection and I can see the produced messages in broker console. I looked up the documentation and here for more explanation but it also says that the strings passed in createConnection method are username and password.
So now, my question is what is the purpose of username and password when they are not used while creating connection?

org.apache.activemq.jaas.guest.role="amq";
};
The username and password are used when creating the connection. The behavior your observing where it doesn't matter what credentials you pass is due to your configuration. You've specifically configured the broker to allow "guest" users (i.e. users with bad credentials or no credentials) via your login.config:
org.apache.activemq.artemis.spi.core.security.jaas.GuestLoginModule sufficient
debug=false
org.apache.activemq.jaas.guest.user="admin"
org.apache.activemq.jaas.guest.role="amq";
You can read more about this login module in the documentation.
If you don't want to allow "guest" users then you can change login.config to be:
activemq {
org.apache.activemq.artemis.spi.core.security.jaas.PropertiesLoginModule required
debug=false
reload=true
org.apache.activemq.jaas.properties.user="artemis-users.properties"
org.apache.activemq.jaas.properties.role="artemis-roles.properties";
};
When the client creates the session, the broker tries to authenticate the client with the passed username and password.
Your login.config file contains 2 login modules PropertiesLoginModule and GuestLoginModule. If PropertiesLoginModule fails the login because of a wrong username/password the GuestLoginModule will login the user admin with the role amq as defined in your login.config file.
Considering a standard installation (5.16.3), when you extract the archive you will find a conf folder.
Starting from there as a base for a Docker container, i had a hard time to configure ActiveMQ security, as there are multiple files involved which partly did not work as expected.
I assume i did not configure everything correctly, as changing login.config had basically no effect.
The only way i got security working was
change jetty-realm.properties for the admin web page access
change activemq.xml for broker security config
(Solution for activemq.xml was found here)
Example config snippet for broker security:
<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}">
<plugins>
<simpleAuthenticationPlugin anonymousAccessAllowed="false">
<users>
<authenticationUser username="admin" password="admin1234!" groups="admins,senders,receivers"/>
<!---<authenticationUser username="user" password="password" groups="users"/>
<authenticationUser username="guest" password="password" groups="guests"/>-->
</users>
</simpleAuthenticationPlugin>

<authorizationEntry topic="ActiveMQ.Advisory.>" write="senders" read="receivers" admin="admins,senders,receivers" />
</authorizationEntries>
</authorizationMap>
</map>
</authorizationPlugin>
</plugins>
.
.
This finally enabled security for Queue access.
I have installed an ActiveMQ broker with JAAS authentication enabled as follows:
activemq.xml
<plugins>
<jaasAuthenticationPlugin configuration="PropertiesLogin" />
<authorizationPlugin>
<map>
<authorizationMap>
<authorizationEntries>
<authorizationEntry queue=">" write="senders" read="receivers" admin="admins" />

login.config
activemq { org.apache.activemq.jaas.PropertiesLoginModule required org.apache.activemq.jaas.properties.user="users.properties" org.apache.activemq.jaas.properties.group="groups.properties" reload=true; };
users.properties
admin=adminpass
Now I am trying from a standalone java client to connect using the following:
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://remote-ip:61616");
// Create a Connection
Connection connection = connectionFactory.createConnection("admin","adminpass");
connection.start();
// Create a Session
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
// Create the destination (Topic or Queue)
Destination destination = session.createQueue("TEST.FOO");
However I get the following in client syserr:
Caused by: java.io.IOException: Configuration Error:

Any ideas what I am doing wrong?
The exception is coming from the JVM itself regarding the syntax of your login.config. The content of your login.config looks fine. Try this syntax:
activemq {
org.apache.activemq.jaas.PropertiesLoginModule required
org.apache.activemq.jaas.properties.user="users.properties"
org.apache.activemq.jaas.properties.group="groups.properties"
reload=true;
};
This should be the only thing in login.config.
The solution to this issue was to make the following changes to my configuration:
login.config(thanks to #justin-bertram for the help)
PropertiesLogin {
org.apache.activemq.jaas.PropertiesLoginModule required
org.apache.activemq.jaas.properties.user="users.properties"
org.apache.activemq.jaas.properties.group="groups.properties"
reload=true;
};
Also setting the following lines in activemq.xml resolved the authorization issue I had:
<plugins>
<jaasAuthenticationPlugin configuration="PropertiesLogin" />
<authorizationPlugin>
<map>
<authorizationMap>
<authorizationEntries>
<authorizationEntry queue=">" write="admins" read="admins" admin="admins" />
<authorizationEntry topic=">" write="admins" read="admins" admin="admins" />
</authorizationEntries>
</authorizationMap>
</map>
</authorizationPlugin>

I would like to apply an Interceptor on the reply-channel of an http:inbound-gateway to save some event related data to a table. The flow continues in a chain which then goes to a header-value-router. As an example let's take a service-activator at the end of this flow, where the output-channel is not specified. In this case, the replyChannel header holds a TemporaryReplyChannel object (anonymous reply channel) instead of the gateway's reply-channel. This way the Interceptor is never called.
Is there a way to "force" the usage of the specified reply-channel? The Spring document states that
by defining a default-reply-channel you can point to a channel of your choosing, which in this case would be a publish-subscribe-channel. The Gateway would create a bridge from it to the temporary, anonymous reply channel that is stored in the header.
I've tried using a publish-subscribe-channel as reply-channel, but it didn't make any difference. Maybe I misunderstood the article...
Inside my chain I've also experimented with a header-enricher. I wanted to overwrite the value of the replyChannel with the id of the channel I want to intercept (submit.reply.channel). While debugging I was able to see "submit.reply.channel" in the header, but then I got an exception java.lang.NoClassDefFoundError: org/springframework/transaction/interceptor/NoRollbackRuleAttribute and stopped trying ;-)
Code snippets
<int-http:inbound-gateway id="submitHttpGateway"
request-channel="submit.request.channel" reply-channel="submit.reply.channel" path="/submit" supported-methods="GET">
<int-http:header name="requestAttributes" expression="#requestAttributes" />
<int-http:header name="requestParametersMap" expression="#requestParams" />
</int-http:inbound-gateway>
<int:channel id="submit.request.channel" />
<int:publish-subscribe-channel id="submit.reply.channel">
<int:interceptors>
<int:ref bean="replyChannelInterceptor" />
</int:interceptors>
</int:publish-subscribe-channel>
Thanks in advance for your help!
The only "easy" way is to explicitly send the reply via the output-channel on the last endpoint.
In fact, all that happens when you send to a declared channel is the reply channel is simply bridged to the replyChannel header.
You could do it by saving off the replyChannel header in another header, set the replyChannel header to some other channel (which you can intercept); then restore the replyChannel header to the saved-off channel before the reply is returned to the gateway.
EDIT:
Sample config...
<int:channel id="in" />
<int:header-enricher input-channel="in" output-channel="next">
<int:header name="origReplyChannel" expression="headers['replyChannel']"/>
<int:reply-channel ref="myReplies" overwrite="true" />
</int:header-enricher>
<int:router input-channel="next" expression="payload.equals('foo')">

</int:router>
<int:transformer input-channel="channel1" expression="payload.toUpperCase()" />
<int:transformer input-channel="channel2" expression="payload + payload" />
<int:channel id="myReplies" />
<!-- restore the reply channel -->
<int:header-enricher input-channel="myReplies" output-channel="tapped">
<int:reply-channel expression="headers['origReplyChannel']" overwrite="true" />
</int:header-enricher>
<int:channel id="tapped">

Test:
MessageChannel channel = context.getBean("in", MessageChannel.class);

String reply = template.convertSendAndReceive("foo", String.class);
System.out.println(reply);

System.out.println(reply); }

Can I send distinct messages (distinct serialize/deserialize) to the same tcp server (same host and port) and differentiate the tcp-inbound-gateway by some value of header or payload with a router???
(...)
I want to add a router for select the correct tcp-inbound-gateway depends on some field in header or payload (for example named typedata). In what order would enter the request (or message) between router, tcp-inbound-gateway, tcp-connection-factory, serialize/deserialize? Will I have problems with the serialization/deserialization for chose the tcp-inbound-gateway? What is the correct way to do this?
Thanks in advance.

You cannot have 2 server connection factories listening on the same port. TCP doesn't allow it - the network stack wouldn't know which server socket to route the request to.
There's no problem on the client side but, with a single socket, the server would have to understand how to deserialize both data types.
It's probably easier to combine the serializers/deserializers into one on both sides (add another header to the message so the deserializer knows what type of payload to decode).
Here's my JmsMessageSender
#Service
public class JmsMessageSender {
#Autowired
private JmsTemplate jmsTemplate;
/**
* send text to default destination
* #param text
*/
public void send(final String text) {
this.jmsTemplate.send(new MessageCreator() {
#Override
public Message createMessage(Session session) throws JMSException {
Message message = session.createTextMessage(text);
return message;
}
});
}
/**
* Simplify the send by using convertAndSend
* #param text
*/
public void sendText(final String text) {
this.jmsTemplate.convertAndSend(text);
}
/**
* Send text message to a specified destination
* #param text
*/
public void send(final Destination dest,final String text) {
this.jmsTemplate.send(dest,new MessageCreator() {
#Override
public Message createMessage(Session session) throws JMSException {
Message message = session.createTextMessage(text);
return message;
}
});
}
}
Here's my DemoClass
public class DemoMain {
public static void main(String[] args) {
// init spring context
ApplicationContext ctx = new ClassPathXmlApplicationContext("context.xml");
// get bean from context
JmsMessageSender jmsMessageSender = (JmsMessageSender)ctx.getBean("jmsMessageSender");
// send to default destination
jmsMessageSender.send("hello JMS");
// send to a code specified destination
Queue queue = new ActiveMQQueue("AnotherDest");
jmsMessageSender.send(queue, "hello Another Message");
// close spring application context
((ClassPathXmlApplicationContext)ctx).close();
}
}

However when I run my main class this error shows. Did I miss anything in the config?
Caused by: javax.jms.JMSException: Could not connect to broker URL: tcp://192.168.203.143:61616. Reason: java.net.ConnectException: Connection timed out: connect
Have you started the AMQ-broker on tcp://192.168.203.143:61616 ? If not then starting it should solve the problem.
Had simillar Errors.
Heres solution.
try to connect to borker at your ip address
Could not connect to broker URL: tcp://192.168.203.143:61616.
above mentioned ip address is relevent to Example's System.
try to run same code for your ip address.(Know your ipAddress in network settings or command "ipconfig")
Could not connect to broker URL: tcp://192.168.1.184:61616.
