    Application Layers Mapped to

    J2EE Tiers and Technology

    J2EE helps developers build layered

    applications, each providing different services

    Java Objects, Entity Beans

    Web Application / JDBC

    Pros

    Simple to build

    Simple to package and deploy

    Low overhead from container

    Relatively easy to test

    Cons

    Needs discipline to keep UI

    and logic separate

    No container transactionsupport

    Must code all database calls

    JSP + Servlet

    UI

    Business Logic

    JDBC

    DB

    Web Container

    Web Application / Local EJB

    Pros Separation of business logic

    Entity beans for persistence

    No serialization or networkcalls

    Concurrency managed

    Can convert to remoteinterface and Web serviceendpoint if required

    Cons Uses EJB infrastructure

    Harder to test business logicbehind local interfaces

    JSP + Servlet

    UI

    Session Bean - Logic

    Entity Bean - Persistence

    DB

    Web + EJB Container

    local

    Web Application / Remote EJB

    Pros Most flexible architecture

    Can separate EJB containerto different server

    Multi client enabled Can be exposed as Web

    service endpoint

    Cons Slower performance, remote

    network calls and serialization Can be difficult to configure

    and debug

    Quotes

    It works well and my machine !!!

    Why it is slower on a my cluster???

    I can not deploy your application! Why my build is broken again?

    Design: J2EE / Web Services

    Understand the different J2EE Components Web Container

    EJB Container

    Infrastructure Services

    JCA, JTA, JMS, Web Services

    Understand Oracle Application Server components

    Look at Open Source project too

    Use Proven Design Patterns Involve System and Database administrators

    Do not reinvent the wheel !

    Development

    Define standards for your team

    Coding standard

    Tooling

    Process

    Use a source control

    JDeveloper integrated with CVS and Subversion

    Automated testing and Build processes Ant, JUnit

  • 8/10/2019 JDev Fusion Middleware

    16/40

    Develop: Presentation Layer

    Model View Controller approach

    Standard Based when possible

    JavaServer Faces

    Apache Struts (de-facto standard)

  • 8/10/2019 JDev Fusion Middleware

    17/40

    Develop: Business Layer

    Should be a reusable Service

    Use J2EE / Standard components

    Session Bean (EJB)

    Web Service

    Limit Remote Calls

    Local invocation of EJB should be the default

  • 8/10/2019 JDev Fusion Middleware

    18/40

    Develop: Persistence Layer

    Data sources are heterogonous RDBMS, XML, Web Services, 3rdPartyApplications

    Use J2EE Services to access these data

    Connection Pooling

    Transaction Management

    J2EE Connector Architecture (JCA/J2CA)

    Java API for XML (JAX-*) JAX-RPC, JAX-P, JAX-B, .

    Develop: O/R Requirements

    Adhere to rules of database

    Build the J2EE application butdo NOT expect to changeschema

    Build the J2EE application but

    the schema might change Be able to profile all SQL calls

    to database

    Let DBA influence/changedatabase calls/SQL generatedto optimize

    Leverage database featureswhere appropriate (outer joins,sub queries, specializeddatabase functions)

    Want to work with objects/beans

    Data model should not constrain

    object model

    Dont want database code in

    object/component code Accessing data should be fast

    Minimize calls to database

    they are expensive

    Object-based queriesnot SQL

    Isolate J2EE app from schemachanges

    Notification of changes to data

    occurring at database

    Test: Prepare Your Success

    Test the application frequently and iteratively

    Unit test components

    Test your application at every milestone

    Functionnality Performance

    Debug

    Testing Solution

    Automated Testing

    Integrated to your IDE, and you Build process

    Junit, testNG, custom code

    Do not make your users the testers !

    Develop: Tools

    Use and IDE such as JDeveloper

    Modeling (UML, Database)

    Help to develop J2EE and Web Services components

    Debugger, Profiler (remotely and locally)

    Integrated with source control software

    Junit, Ant, Maven integration for easy testing and build

    Java, XML, HTML, PL/SQL editors

    Easy Deployment

    Standards and Guidelines

    It is important to develop consistent

    standards, guidelines, documentation,

    deployment and packaging methods.

    Look at sources such as Java Blueprints and

    the Oracle Technology Network for guidelines.

    Understand how to leverage design patterns

    and frameworks within your applications.

    Packaging

    Development teams need to understand how their softwarecomponents need to be packaged for the types of applicationsthey are building.

    The choice of packaging will have an impact on how anapplication will work and act in a distributed environment.

    Packaging needs to consider: The type of archive files to use.

    The types of deployment descriptors for particular platforms.

    Deployment profiles are created in a project when usingJDeveloper. Separate profiles are required for differentdeployment targets. Verify that JDeveloper can find all the

    necessary library files (i.e. Swing). Be aware that different Java files (Applets, JSPs, Servlets, EJBs,

    etc.) all reside in different locations.

    Precompile your JavaServer Pages for better performance

    Deployment Options

    Make sure to clearly understand the deployment

    options available in each deployment, test and

    production environment

    Use deployment Plan (new standard for J2EE 1.4)

    If the build process is complex, tools like Ant and

    JSR-88 may provide the flexibility and the cross

    platform capability necessary.

    JDeveloper and the Oracle Application Server providea lot of flexibility for deployment environments.

    JSR-88: J2EE Deployment API

    J2EE applications can be made portable acrossvendor implementations

    No standard existed for deployment of the portableapplication

    JSR-88 fills the void Standard API and operations for deployment of applications

    to J2EE containers

    Vendor specific configuration abstracted from actualdeployment process

    Expected to be an API consumed largely by toolsvendors

  • 8/10/2019 JDev Fusion Middleware

    JSR-88 Capabilities

    Deployment of all J2EE component types

    Configuration of an application for deployment

    Asynchronous deployment

    Canceling of deployment and undeployment

    operations

    Progress notifications

    Connected and disconnected usage

    Optional support for re-deployment operations
