Advanced Lanjan Model WAP (Web Application Platform) Theory
In this blog post, we will delve deeper into the theory of the advanced Lanjan Model WAP (Web Application Platform). The Lanjan Model, developed by Dr. Heru Cahyanto from Universitas Indonesia, is a comprehensive framework for building web applications using Java EE technology. The advanced version of this model includes several improvements and additions to cater to the evolving needs of modern web applications.
Architecture
The advanced Lanjan Model WAP consists of five main components:
- Presentation Component: This is the user interface part of the application, responsible for rendering views and handling user interactions. It utilizes technologies like JSF (JavaServer Faces) and PrimeFaces for building rich and interactive user interfaces.
- Business Component: This layer handles the business logic of the application. It contains entities, services, and validators that perform complex operations on data. Business components are typically implemented using Java EE technologies like EJBs (Enterprise JavaBeans) and CDI (Contexts and Dependency Injection).
- Integration Component: This layer is responsible for integrating the application with external systems or services, such as databases, email servers, or payment gateways. It uses standard protocols like JDBC, JMS, or REST to communicate with these systems.
- Security Component: This layer ensures the security of the application by implementing access control and authentication mechanisms. It utilizes technologies like Java EE Security and Jersey Security to provide role-based access control and secure API endpoints.
- Deployment Component: This is the final component that deploys and runs the web application in a servlet container like GlassFish or Tomcat. It also manages the application's dependencies, such as Java EE APIs and third-party libraries.
Benefits
The advanced Lanjan Model WAP offers several benefits over other web application development frameworks:
- Standardization: By following the Java EE standards, the advanced Lanjan Model ensures compatibility with various containers and tools, making it easier to develop, test, and deploy applications.
- Maturity: Java EE technology has been around for decades, which means that there is a rich ecosystem of libraries, frameworks, and tools available to developers. This maturity translates into better performance, scalability, and security.
- Flexibility: The advanced Lanjan Model allows developers to choose the technologies they prefer for each layer of their application. For example, you can use JSF or Thymeleaf for presentation, EJBs or Spring Boot for business logic, and JDBC or Hibernate for integration.
- Modularity: The Lanjan Model's modular structure makes it easier to maintain large-scale web applications by separating concerns and promoting code reusability.
Conclusion
The advanced Lanjan Model WAP is an excellent choice for building robust, secure, and scalable web applications using Java EE technology. Its well-defined architecture, flexibility, and standardization make it a popular choice among developers and organizations that demand high-performance and reliable web solutions.
