<!-- Tomcat  with JMS(ActiveMQ) & MySQL integration -->

Step 1 : Required Jars

--> Copy active-all-5.5.0.jar from  apache-activemq-5.5.0  Home Directory.

--> Download javassist-3.8.0.GA.jar, mysql-connector-java-5.1.6-bin.jar, slf4j-api-1.5.11.jar, slf4j-simple-1.5.11.jar

--> Paste the above jars in  Tomcat/lib Directory.

(Note :Dont copy this active-all-5.5.0.jar in your project library) 

Step 2 : Copy activemq.xml file into your Tomcat/conf directory from apache-activemq-5.5.0.

Step 3: Configure JNDI ActiveMQ Settings & Database Settings in contex.xml file in Tomcat/conf Directory.

 --> We should configure the properties in Resource Tag, Under <Context> root

  Step 4: Add ActiveMQ reference in  your application's messaging-config.xml file

  --> Copy the following properties from context.xml file and configure in messaging-config.xml file

    --> Find the following properties from context.xml file from <Resource> tags. and paste in messaging-config.xml files 

 1) Find the name property  where type = "org.apache.activemq.ActiveMQConnectionFactory"  and copy the value and paste in messaging-config.xml's <connection-factory>

 2) Find the property type = "org.apache.activemq.ActiveMQConnectionFactory"  from  <Resource>  tag in context.xml 

    and copy the name property value and paste in <connection-factory> in messaging-config.xml under <jms> tag

 3) Find the property brokerUrl = "tcp://localhost:61616" and copy the value in messaging-config.xml's  <inital-context-environment>.

 4) Find the name property where type = "org.apache.activemq.command.ActiveMQTopic" and copy the value and paste in messaging-config.xml's <destination-jndi-name>

 Step 5: Add url in your application's services-config.xml file
