I'm not sure what you mean by "as you have explained it for EJB" but to start out with you'll need a messaging product. This is the product that provides your basic messaging service, e.g. MQSeries, SonicMQ, OpenJMS etc.
Once you have that up and running you use the JMS API in your Java application to send/receive messages.
You don't need to use the JMS API as most messaging vendors provide a Java API into their product.
The good thing about JMS though is that even if you change messaging vendor your programs won't (shouldn't have to anyway) change.
