title: how to learn Drools or another rule engine fast
body: <p>We're embarking on a module which will generate some recommendations based on some criteria. The criteria will be in the form of set of Business Rules and hence I was considering using a Business Rule Engine like Drools(open source and java :-) )</p>
  
  <p>we need to learn Drools fast (2-3 weeks) and be able to implement rules using JBoss Drools. Which articles, tutorials, books, best practices should we be following ?</p>
