Message Types (http://docs.oracle.com/javaee/6/api/javax/jms/Message.html)
	- String - Commonly used to avoid versioning issues
	- Object (serialised)
	- ByteMessage
	- MapMessage
	- StreamMessage
	
JNDI
	- Java Naming Directory Index
	- Dependancy Injections
	- Beans, Queues, Connection Factory
	
Queue Implementations
	- e.g. Jboss, activemq, rabbitmq...
	- Implement JMS API
	
Queues + Topics
	- Queue consumed by one
	- Topic consumed by all
		- Problems if consumer is off
		
Connection factory
	- Object a client uses to create a connection with a provider.

Setup using Glassfish Queue (JMS)

	export JAVA_HOME=$(/usr/libexec/java_home);
	export J2EE_HOME=/Users/iboddington/glassfish4/glassfish;
	export CLASSPATH=.:/Users/iboddington/glassfish4/mq/lib/*:/Users/iboddington/glassfish4/glassfish/modules/*;
	export DISPLAY=:0;

	Needed CLASSPATH as above to get below to compile (example Sender / Receiver from tutorial):

	javac SimpleQueueSender.java
	javac SimpleQueueReceiver.java

	java -Djms.properties=$J2EE_HOME/config/jms_client.properties SimpleQueueSender jms/testQueue 3
	java -Djms.properties=$J2EE_HOME/config/jms_client.properties SimpleQueueReceiver jms/testQueue


	Glassfish Install
		1. Download / Install Java EE / glassfish: http://www.oracle.com/technetwork/java/javaee/downloads/index.html
		2. Setup env vars
			export JAVA_HOME=$(/usr/libexec/java_home);
			export J2EE_HOME=/Users/iboddington/glassfish4/glassfish;
			export CLASSPATH=.:/Users/iboddington/glassfish4/mq/lib/*:/Users/iboddington/glassfish4/glassfish/modules/*;
			export DISPLAY=:0;
			alias glassfish='/Users/iboddington/glassfish4/glassfish/bin/startserv';
		3. Startup using glassfish alias
		4. Go to console: http://localhost:4848/
		5. Under Resources > JMS Resources > Connection Factories, create a new queue connection factory e.g. jms/testQueueConnectionFactory
		6. Under Resources > JMS Resources > Connection Factories, create a new topic connection factory e.g. jms/testTopicConnectionFactory
		7. Under Resources > JMS Resources > Destination Resources, create a new queue e.g. jms/testQueue
		8. Under Resources > JMS Resources > Destination Resources, create a new topic e.g. jms/testTopic

	
	Queue / Topic Client Setup (for glassfish)
		1. Create files from: http://docs.oracle.com/javaee/1.3/jms/tutorial/1_3_1-fcs/doc/client.html
		2. Change connection factory, queue and topic names to those created in glassfish
		3. Compile them (Needed CLASSPATH as above to get compile / run to work)

		To run: 
			java SimpleQueueReceiver jms/testQueue //Will end once message received
			java SimpleQueueSender jms/testQueue <num>

			java SimpleTopicSubscriber jms/testTopic <num> //Will wait and listen (can have multiple)
			java SimpleTopicPublisher jms/testTopic
		
		Client basics:
			Create context
			Lookup connection factory and queue or topic (by name)
		
			Create connection, create session...
		
ActiveMQ Setup

	wget http://www.apache.org/dyn/closer.cgi?path=/activemq/5.11.1/apache-activemq-5.11.1-bin.tar.gz
	Move to apps
	Untar in apps
	Check executable permissions
	
	Run from apps/apache-ac....
	bin/activemq
