JavaBeans Component Architecture

By: aathishankaran in Java Tutorials on 2007-02-22  

JavaBeans is a component architecture that defines a standard for developing reusable software components for Java. JavaBeans components are self-contained, reusable software units that can be used in various applications.

JavaBeans components are typically designed to work together and can be combined to create larger and more complex applications. They are used in a wide range of applications, including web development, GUI development, and database applications.

The JavaBeans component architecture defines a set of conventions for creating and using components. A JavaBeans component is a Java class that follows these conventions:

  1. Serializable: The class must implement the Serializable interface so that it can be stored and retrieved from a persistent store.

  2. No-argument constructor: The class must have a public no-argument constructor so that it can be instantiated by tools and containers.

  3. Properties: The class must define properties that can be accessed and modified by tools and containers.

  4. Events: The class must define events that can be generated and handled by tools and containers.

  5. Naming conventions: The class must follow a standard naming convention for its properties and methods so that tools and containers can automatically discover and use them.

JavaBeans components can be used in a wide range of environments, including web servers, application servers, and desktop applications. They are designed to be reusable, easy to use, and portable across different platforms and environments.
