== Què és una aplicació Java Web?

Una aplicació Java Web genera pàgines web interactives que contenen diversos tipus de llenguatges de marcatge (HTML, XML, i d'altres) i contingut dinàmic. Aquest està típicament contingut en components web, com les pàgines JavaServer (JSP), servlets i JavaBeans, per modificar i emmagatzemar temporalment les dades, interactuar amb bases de dades i serveis web, i subministrar contingut en resposta a peticions de clients.

Degut a que algunes tasques involucrades en el desenvolupament d'aplicacions web poden ser repetitives o poden necessitar un excés de codi que fàcilment es pot re-aprofitar, es poden aplicar els frameworks web per alleugerar la sobrecàrrega associada a activitats comuns. Per exemple, alguns frameworks, com JavaServer Faces, proporcionen biblioteques per a l'acomodament de pàgines i gestió de sessions, i de vegades difonen la reutilització del codi.

=== *Què és Java EE?*

Java EE (Edició Empresarial) és una plataforma extensament utilitzada que conté un conjunt de tecnologies coordinades que signifiquen la reducció de costos i la complexitat del desenvolupament, desplegament, i gestió multi-tutelada d'aplicacions centralitzades al servidor. Les construccions de Java EE estan per damunt de la plataforma Java SE i proporcionen un conjunt d'APIs (Interfícies de Programació d'Aplicacions) per al desenvolupament i l'execució d'aplicacions en el cantó del servidor portables, robustes, escalables, de confiança i segures.

Alguns dels components fonamentals de Java EE inclouen:

* JavaBeans Empresarials(EJB): una arquitectura de component gestionada en el cantó del servidor, utilitzada per a encapsular la lògica de negoci d'una aplicació. La tecnologia EJB permet un desenvolupament ràpid i senzill d'aplicacions distribuïdes, transaccionals, segures i portables, basades en tecnologia Java.
* API Persistència Java (JPA): un framework que permet als desenvolupadors gestionar dades mitjançant el mapeig relacional d'objectes (ORM) en aplicacions construïdes en la plataforma Java.
