Beginning EJB3 with JBoss and MySQL

Here, I am going to show how to begin with EJB and deploy in JBoss server. For this example, I am using MySQL database.

Prerequisites for this example:
- JBoss
- Eclipse
- MySQL

Spring and Drools

Let us assume that we have dozens of rules that we have to implement, divide into some classes, subclasses, abstractions and of course unit test. This can be difficult and time consuming to both write and support. There are many ways of dealing with this problem and following example leverages one of them - JBoss Drools. Drools is a library specifically created for such purposes like implementing rules. It contains a rule engine that can process rules written using the Drools language (you can also provide rules in Excel spreadsheets! - perfect for Business side to support and management). Here, we will take a look at the way one can integrate JBoss Drools with Spring. (Reference: http://java.dzone.com/articles/drools-integration-spring-vs)
