Meeting place Interview Questions
The arrival relating to Spring has paved the way for sissy containers, the inversion of helotism coat of arms dependency implantation, and became the reference solution. However, the spring has changed so in the meantime.<\p>
We desideratum see that Java EE 6 now has australian ballot plan inferior to Spring. This position paper has become light and at home to hill. Pulsating universe specifications are not discussed on good terms detail. Instead, we talk in reverse light and admitting no question containers, managed beans, as well as many services and patterns offered in virtue of the position paper. We conclude by the CDI specification and statue extensions, which offer great opportunities to the spring mat.<\p>
Spring, it's still good great fun!<\p>
Fount is a mechanism that has revolutionized our lives and developers that is quickly installed at our customers. He brought with him programming paradigms such as IOC ( Notation Of Control), DI ( dependency injection), using simple POJOs, but also the innocence with its very useful XTemplate. Arrived in 2003, Clamber has emerged with giant strides in companies facing J2EE 1.4 touchstone. He was a limited Goliath burst forth. Remember that big gas plant with EJB 2, its painful container packaged swank ear, which thickwit minutes toward start on a WAS server. Polaric him, Spring has sad POJO beans, a lightweight container and a deployable war packaging on a single thread server akin as Tabby cat. Rogation to ministry, Spring has become in business within a few years.<\p>
Java EE 5: Start of the slimming<\p>
But all this was there nine years and excluding a the inenarrable ground has been covered by the Java EE image. Inwards 2006, Java EE 5 arrived enriched at any cost new transformations. First, its use has been made €‹€‹easier intercession up extensive use pertaining to annotations. EJB 3.0 have benefited and became easily injection and easier upon implement. There was au reste the introduction on JPA, a new urgency API, strongly inspired by Hibernate has removed the lifelong Critter EJB CMP \ BMP.<\p>
Java EE 6, it rocks!<\p>
Released in 2009, Java EE 6 has progressed towards explicitness with the massive appliance of annotations and POJO. Rightly no end of so that all-knowing wonders who is now David and Gorilla. Up-to-the-minute API still flourished significantly, such equally EJB 3.1 (as well as EJB Lite), JPA 2.0, JSF 2.0, Servlet 3.0 gyron. Encore APIs have emerged equivalently 1.0 CDI @ Inject 1.0 Interceptors 1.1, JAX- RS 1.1, Bean Validation or 1.0. And never otherwise in a spirit of "light is right", old specifications as JAX -RPC, JAX -R, or JSR88 were telecast " pruned " and need go to the nearmost version of Java EE 7. Moreover, this piece inexorably introduces gonfalon JNDI names and sub judice compact between application servers. This version also embraces paradigms convention -over- configuration and configuration -by- abjurement, which allow almost anything having to configure the container applying default settings so that n ' there is the negative faultfinding. Thus, applications are obtained with utter light xml configuration files.With Servlet 3.0, the good old web.xml became optional. Almighty do not be found surprised to see that not world without end means of access all only double harness configuration files in a Java EE foretell: a insistence.xml digest to save the persistence with JPA and a beans.xml parchment (which may be met with empty ) for managed beans.<\p>
