Enterprise Application Development

Enterprise application development requires that code be developed and tested with multiple components and subsystems in order to execute properly under a variety of runtime conditions. An enterprise application will consist of three layers: 1- Presentation Layer  2- Business Logic Layer  3- Data Layer. The Presentation Layer utilizes dynamic programmatically generated HTML content which is supported by containers that maintain session state, security, and configuration. Tag libraries are used to improve readability for coding; it is a custom defined JSP tag. The Business Logic Layer provides common enterprise computing tasks such as processing transactions, creating XML web services, or calling methods on distributed remote objects to execute business rules based on triggering events or messages. The Data Layer is stored in a relational commercial or open source database management system.

The ability to develop and deploy applications is essential to information driven organizational enterprise. Applications need to go quickly from prototype to production, and then be revised and improved after deployment.  A number of factors can impact an organization's ability to deliver custom applications efficiently and maximize value over the application lifecycle.

The major challenges are to:

  • Reuse the business logic in the existing information technology infrastructure.

  • Design distributed enterprise applications to scale and implement automated change in use patterns and system configuration.

  • Integrate disparate systems in a unified security model while maintaining tight security over the most sensitive assets and efficient access to others.


Java: Development Platform and Language

Java is both a development platform and language for coding, debugging, and distributing enterprise applications. It is available as FOSS: free of charge open source software. However, mission critical enterprise application development typically is done with a commercial Java platform such as Oracle WebLogic or IBM Rational. The Java platform provides infrastructure services for use in high-level language APIs for efficiently performing enterprise-level programming tasks. The J2EE technology stack is a set of specifications comprised of these components:

EJBs: Enterprise JavaBeans Hibernate HotSpot VM 1
JCA: Java Connectivity Architecture JDBC: Java Database Connectivity 1 JMS: Java Messaging Service
JSP: JavaServer Pages JMX: Java Management Extensions JNDI: Java Naming and Directory Interface
Servlets Spring Struts

A well designed enterprise application will deliver integrated functions: accessing databases, messaging, e-mailing, parsing XML, networking, supporting telephony, running web applications, etc.

The Java language implements an object oriented programming model; has a wide acceptance for use in writing portable, cross-platform code.  Java creates and controls objects in conjunction with making the objects work together. An object has properties and behaviors. Properties are described through the use of data and behaviors through the use of methods. In the Java language, objects are defined through the use of classes. A class is a form of template for the objects and an object is the actualization of a class description. Instantiation is the process of creating an object class. Java is composed of classes arranged in a treelike hierarchy; a child class is able to inherit properties and behaviors from its parent class. The major commercial versions of Java distributed and sold by the software companies are: Oracle Corporation's WebLogic / JDeveloper and IBM Corporation's WebSphere / Rational. The Java code runs in a controlled execution environment which provides infrastructure services: memory management, security, checks, and type validation to the compiled or intercepted code. The JVM: Java Virtual Machine runs only byte code devoid of pointers.

There are significant advantages associated with Java. While other programming languages have to call operating-system procedures in order to enable multithreading, the multithreading capability has been included in the Java base code. The CPUs of the new computer hardware have 2,4, or 6 cores and many servers have multiple CPUs. Applications coded with the Java language have significant advantages in using multitasking to present and control sounds, images, graphics, and video. The Java language and specialized SDKs are being increasingly used in multimedia applications: sound, graphics, video, and animation. It is common place for web applications, mobile devices, and PDAs to have integrated multimedia capabilities.


Java Runtime Architecture

A single JVM instance maps to a single operating system process. Multiple applications can run on a single JVM, but there is no logical partitioning of the applications inside a JVM. All applications inside a JVM share the same process resource. This makes interapplication communication inside a JVM or in-process communication fast and easy. However, a single rogue application consuming a lot of memory can impact an entire JVM instance and affect other applications running on the same JVM instance.  

Out of-process communication is implemented through RMI; Remote Method Invocation and serialization, which are the foundation of distributed computing in Java. EJBs distributed on different JVMs communicate with each other through RMI calls. A JVM instance is lighter than an operating system process and can be embedded in devices. A JVM instance can be hosted by an application server or can be run as a stand-alone program. A Java application directly interacts with external code through: 1- components or subsystems such as a database or graphics  2- an operating system such as Windows, Linux, or z/OS or  3- runtime conditions such as hardware, available memory, processors, and server modes.  


Java and JDBC

Java has abstracted out the raw SQL calls to any database into the JDBC. The JDBC API provides everything you need to access an enterprise API. The API is used to interact with a JDBC driver, which is the pipeline through which the SQL goes to the database server. J2EE supports two approaches to accessing this data. One is through BMP: bean managed persistence, which essentially uses the JDBC driver to make the raw SQL calls to the underlying database. In the second approach, CMP, container managed persistence, object relational mapping is used for mapping objects to the database tables, thereby providing automatic persistence to the database without needing to generate the raw SQL.

Java Training by SYS-ED

SYS-ED system consultants and CETi Technology Partners have been in the forefront of client/server and web enablement software technologies. We are experienced with the 1- open source and commercial web server environments - Apache, WebSphere, WebLogic, Oracle, and IIS  2- integrated development environments - Eclipse and Rational 3 - Java frameworks and utilities. Equally as important, our staff are recognized experts with industry leading IBM WebSphere MQ middleware and the alternative commercial and open source middleware:

In addition to IBM WebSphere MQ, there are commercial and open source Service Oriented Architectures that support web services and message-based technologies. 

SOA Service Oriented Architectures Description
Open Message Queue OpenMQ is an open source message-oriented middleware project that implements the Java Message Service 1.1 API. In addition to supporting the JMS API, OpenMQ provides clustering, a C API, and a full JMX administration API. The JCA Java EE Connector Architecture allows OpenMQ to be used by a Java EE compliant application server. It is the default JMS provider integrated into GlassFish.
Apache ActiveMQ Open source message broker which implements JMS: Java Message Service 1.1 It also can be used from .NET, C/C++ or Delphi or from scripting languages like Perl, Python, PHP, and Ruby in conjunction with Cross Language Clients.
JBoss Messaging The JBoss enterprise asynchronous messaging system is the default JMS: Java Message Service provider in the JBoss SOA Platform and JBoss Application Server.
TIBCO Enterprise Message Service Standards-based enterprise messaging platform on a common enterprise backbone for managing real-time flow of information. It is the foundation of TIBCO's event-driven SOA for enabling synchronous and asynchronous system-to-system communications in Java EE, .NET, C, C++, TIBCO Rendezvous, TIBCO SmartSockets, and COBOL and Assembler on the mainframe.

 

SYS-ED’s Java curriculum is comprised of industry standard courses and advanced consultancy derived courses. Our  core Java programming language curriculum have been submitted to submitted to the New York State Department of Education - Bureau of Proprietary School Supervision. 

 

As an independent training company with longstanding experience in hybrid operating environments, the SYS-ED training service provides guidance and educational consultancy on SOA: Service Oriented Architecture and cloud computing application development.

Java Educational Consultancy

Java and EJB Java and WebLogic


Upon completion of a Java course and training program, clients are invited to submit Java questions from back on the job. SYS-ED staff and CETi Technology partners answer, explain, and where applicable reference source documentation. This commitment to excellence is why we get requests from software companies to train their clients and software engineers. Consulting companies utilize our services for accelerated training for staff that will be responsible transitioning to clients new development platforms. Few software or consulting companies have been teaching the Java programming language training longer or better.

Qualifying a Java Training Assignment

SYS-ED will not accept a Java training assignment without a consultation with the prospective client organization.  We review the background of the employees to be trained, operating environment, standards, project specifications, and standards, and use that information to select the code snippets, examples, skeleton programs, and hands-on exercises. We then prepare a training strategy: lesson plan, courseware, training aids, and validation assessment. The pre course consultation allow us to identify and differentiate between  teaching an industry standard course as compared to the client’s true need for educational consultancy - structured analysis, structured design, and code reengineering. We use this foundation in order to train employees from Fortune 1000 companies, government municipalities, and healthcare providers to upgrade and migrate the existing investment in client/server infrastructure to Java and develop applications for mobile devices. And when are not confident that we can provide a superior Java training outcome, will politely turn down an assignment.


Courseware Superior by Design

The courseware and training aids used in SYS-ED instructor-led and distance-learning courses is highly respected. The content incorporates an analysis of the program logic and sample programs which have been validated on consultancy projects. We review information in the public domain distributed by software companies, international standards committees, and purveyors of open source software. We perform our own independent analysis of white papers and benchmarks for software updates and new products. Content is interpreted and selectively incorporated into our student hand-outs. Given the intermixing and hybrid implementation of commercial and open source software, reference material which demonstrates and explains will be fundamental to an effective training experience. As part of presenting an instructor-led course at the client location, courseware is organized for subsequent use in a web-based infrastructure and delivery medium. Few training companies have the library of sample programs, workshops, and customized training aids that we do.
