Written for enterprise Java developers who have become disillusioned
with the complexity and bulk  involved with EJB development, this
programming tool demonstrates how the Spring framework can make coupled
code easy to manage, understand, reuse, and unit-test. Spring's
employment of inversion control and aspect-oriented programming
techniques to encourage  loosely coupled code is explained,
providing programmers with the ability to use JavaBeans with the power
and enterprise services  only previously available in the heavier
Enterprise JavaBeans.
