IoC Inversion of Control

 

e.g. Spring framework

accessed from org.ctef.los.ctrls

1. OrderingCtrl.java (src -> control code)
2. web.inf / conf. / beans
   

Modeling => DAO (Data Access Object)
View => jsp

Controller => controlled by xml

In OrderingCtrl.java :
@Request Mapping("filename")

your code calls (sth) vs the framework calls (sth you written)

e.g. Database class, don't want to initialize (new) every time

create in framework itself, our code calls the existing created object when required

Dependency Injection

Inject created object as parameter rather than create in class
