Java APIs: JMS, JDBC, JTA

Study Notes

JMS is an API for sending and receiving messages asynchronously between distributed applications
Supports both point-to-point and publish-subscribe messaging models

JDBC is an API for connecting Java applications to relational databases
Provides a standard way to execute SQL queries, update data, and perform other database operations from Java programs

JTA provides APIs for managing distributed transactions in Java EE applications
Allows applications to define and control transaction boundaries, ensuring data consistency and reliability across multiple resources

JPA is a standard API for object-relational mapping (ORM) in Java EE applications
Allows developers to map Java objects to relational database tables and perform CRUD operations using object-oriented semantics

JAX-RS is an API for building RESTful web services in Java EE applications
Simplifies the development of web services that follow the REST architectural style, using annotations to define resources, URIs, and HTTP methods

JAX-WS is an API for building SOAP-based web services in Java EE applications
Provides annotations and APIs for defining web service endpoints, operations, and data types

Java EE provides a range of security services for authentication, authorization, data integrity, and confidentiality
Features include declarative security, role-based access control, SSL/TLS support, and encryption

CDI is a dependency injection framework that allows components in a Java EE application to be loosely coupled and easily managed

Component-based, multi-tier, distributed architecture
Key concepts include security, scalability, transaction management, reliability, and management

Reusable software components or objects written in Java that follow certain conventions
Key points:
- POJOs (Plain Old Java Objects)
- Properties and Methods (private fields with public getter and setter methods)
- Serializable (implements the Serializable interface)
- Reusability (designed for reusability across different components of a Java application)

Java classes that extend the capabilities of servers and respond to requests from web clients
Key points:
- Server-side Logic (provide server-side logic for processing client requests and generating dynamic content)
- HTTP Request Handling (handle various types of HTTP requests, such as GET, POST, PUT, DELETE, etc.)
- Extensibility (can be extended to support advanced features like session management, authentication, authorization, and more)
- Performance (offer better performance compared to traditional CGI scripts)

Technology that allows developers to create dynamic web pages by embedding Java code within HTML
Key points:
- Mixing Java with HTML (embed Java code directly into HTML pages using special tags)
- Simplifying Development (simplifies web application development by enabling developers to write dynamic content directly within HTML pages)
- Tag Libraries (supports custom tag libraries, such as JSTL and custom tag libraries, providing reusable components for common tasks)
- Separation of Concerns (recommended to maintain a clear separation of concerns by using MVC architecture or frameworks like Servlets + JSP + JavaBeans)
