Spring and EJB

[David Ulicny]

I'm new to Spring and EJB's as well. Is there any relationship between Spring and EJB technology?

Here is a sample from the book

If I understood it good, Spring just simulate the EJB's, right?

Spring is more like a light weight approach to what EJBs are trying to achieve.

It is more of a replacement for some parts of EJB spec that are not easy to work with & unnecessarily complicated( like entity beans)

Hi,

Spring is more of a framework. Please read this.

Spring can make the use of EJB an implementation choice, rather than the determinant of application architecture. You can choose to implement business interfaces as POJOs or local EJBs without affecting calling code.

Spring helps you solve many problems without using EJB. Spring can provide an alternative to EJB that�s appropriate for many web applications. For example, Spring can use AOP to deliver declarative transaction management without using an EJB container; even without a JTA implementation, if you only need to work with a single database.
