Basic examples

These examples are relatively simple WBI plugins. You can just run them to try them out or study their source code to learn the basic concepts of how to program a plugin. We recommend you read the pages on Architecture and Programming to fully understand plug-in programming.

Demo
The demo plugin illustrates a few simple ways to use WBI. It is described at some length in the programming section.

PageFilter
The Page Filter plugin blocks a web browser from displaying sites that are not on a list of approved sites. This example demonstrates the use of the Section class, as well as the use of request editors and generators.

Yahoo Categories
The Yahoo Categories plugin is designed to keep track of the Yahoo categories a user visits over time. This example demonstrates the use of the Section class, as well as the use of monitors and generators.

AnnotateUrl
This plugin color codes links. It demonstrates use of a setup page to set plugin preferences and how to put a custom style sheet into every page using a LinkAnnotationEditor

WebServer
Demonstrates how to write a simple web server using several of WBI bean classes. This web server is configurable from a property file and comes set up to serve the WBI DK documentation. This plugin demonstartes the use of the Section class, as well as the use of several beans, such as FileGenerator and CgiGenerator.

We also have more advanced examples.
