INVERSION OF CONTROL(DEPENDENCY INJECTION) - IOC

04/10/2313

inversion of control - IoC

Hollywood principle

Don’t call me, I’ll call youDon’t call me, I’ll call you

04/10/2314

inversion of control - IoC

IoC – is a common characteristic of frameworks.Inversion of Control serves as a design guidelineAccording to Martin Fowler the etymology of the phrase dates back to 1988

04/10/2315

inversion of control - IoC

In OO Design, components/objects are desired to be reusableHowever, components depends with one another to deliver the solutionSuch dependencies among components results the tight coupling

SPRING FRAMEWORK AND JEE

04/10/2325

spring framework and jee

It’s hard to say whish is the best

04/10/2326

spring framework and jee

Spring

Spring is framework and single vendor solutionsHas made tremendous contributions to the development communitySupports for almost any web container

Jee

JEE is standardJava Community Process Program - Java Specification Request(JSR)JEE needs application server(glassfish, jboss, weblogic etc.)

04/10/2327

spring framework and jee

Spring

Have a look at the job postings in Monster or Dice. A very large proportion of Java jobs require Spring experienceThere has been a lot of innovation lately in the cloud space

Jee

Java finally woke up and responded with Java EE 6JEE, JSF 2.0 is more critical. Java badly needs a modern MVC framework
