JBoss Fuse - AMQ With Camel

In this chapter, we will learn the basics of how ActiveMQ works with Camel.
Before we can use ActiveMQ queue or topic in our code we have to configure ActiveMQComponent. Minimal configuration of ActiveMQComponent can be done as shown in the following program −
<bean id = "activemq" class = "org.apache.activemq.camel.component.ActiveMQComponent">
   <property name = "brokerURL" value = "tcp://localhost:61616"/>
   <property name = "userName" value = "admin"/>
   <property name = "password" value = "admin"/>
</bean>
brokerURL − Specifies host and port for AMQ Broker.
brokerURL − Specifies host and port for AMQ Broker.
username − Specifies username to use for connecting to AMQ Broker.
username − Specifies username to use for connecting to AMQ Broker.
password − specifies password for connecting to AMQ Broker.
password − specifies password for connecting to AMQ Broker.
Now that we have configured ActiveMQComponent, we can use it in our CamelContext as endpoint.
We will use AMQ endpoint in the following format −
Activemq:[queue|topic]:[queueName|topicName]

<?xml version = "1.0" encoding="UTF-8"?>
<!-- Configures the Camel Context-->
<beans xmlns = "http://www.springframework.org/schema/beans"
   xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation = "http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://camel.apache.org/schema/spring
   http://camel.apache.org/schema/spring/camel-spring.xsd">
After deploying this bundle in Fuse container, you should be able to see messages posted to AMQ which were placed as files in D:/src/data.
Input
D:/src/data/input.txt

      <property name = "password" value = "admin"/>
   </bean>
	
</beans>
Input
After deploying this bundle, you should see a file being generated in D:/src and messages are consumed. Also Consumer should be shown for that Queue.
Output
D:/src
