context module, providing a context that is
appropriate for web-based applications. This module also contains
support for several web-oriented tasks such
as transparently handling multipart requests for file uploads and
programmatic binding of request parameters to
your business objects. It also contains integration support with
Jakarta Struts. .... Http://capptitudebank.blogspot.in
What are object/relational mapping
integration module?
Answer :: Spring also supports for using of
an object/relational mapping (ORM) tool over straight JDBC by
providing the ORM module. Spring provide
support to tie into several popular ORM frameworks, including
Hibernate, JDO, and iBATIS SQL Maps.
Spring’s transaction management supports each of these ORM
frameworks as well as JDBC. .... Http://capptitudebank.blogspot.in
What is JDBC abstraction and DAO module?
Answer :: Using this module we can keep up
the database code clean and simple, and prevent problems that
result from a failure to close database
resources. A new layer of meaningful exceptions on top of the error
messages given by several database servers is
bought in this module. In addition, this module uses
Spring’s AOP module to provide
transaction management services for objects in a Spring application.

What is AOP module?
Answer :: The AOP module is used for
developing aspects for our Spring-enabled application. Much of the
support has been provided by the AOP Alliance
in order to ensure the interoperability between Spring and other
AOP frameworks. This module also introduces
metadata programming to Spring. Using Spring’s
metadata support, we will be able to add
annotations to our source code that instruct Spring on where and how
to apply aspects. .... Http://capptitudebank.blogspot.in
What is Application context module?
Answer :: The Application context module
makes spring a framework. This module extends the concept of
BeanFactory, providing support for
internationalization (I18N) messages, application lifecycle events, and
validation. This module also supplies many
enterprise services such JNDI access, EJB integration, remoting,
and scheduling. It also provides support to
other framework. .... Http://capptitudebank.blogspot.in
What is the Core container module?
Answer :: This module is provides the
fundamental functionality of the spring framework. In this module
BeanFactory is the heart of any spring-based
application. The entire framework was built on the top of this
module. This module makes the Spring
container. .... Http://capptitudebank.blogspot.in

(Object/Relational)
Web module
MVC framework module

Explain Spring in detail?
Answer :: Inversion of control (IoC) : Loose
coupling is achieved in spring using the technique Inversion of
Control. The objects give their dependencies
instead of creating or looking for dependent objects.
Lightweight : Spring is lightweight when it
comes to size and transparency. The basic version of spring
framework is around 1MB. And the processing
overhead is also very negligible.
Aspect oriented (AOP) : Spring supports
Aspect oriented programming and enables cohesive development
by separating application business logic from
system services.
Container : Spring contains and manages the
life cycle and configuration of application objects.
Framework : Spring provides most of the intra
functionality leaving rest of the coding to the developer.
