iBeans aims to make integration for Web applications much easier than it is today. It does this by focusing on simplicity and task-based integration and avoids technical jargon and new concepts wherever possible. It offers easy to use integration for doing things like publishing and subscribing to JMS queues and topics, sending and receiving email, polling resources such as databases and ATOM feeds, task scheduling, creating HTTP/Rest services, consuming external services such as Amazon EC2 and S3, Twitter, Flickr, Google, and much more. It proves a Tomcat distribution that drops straight into Tomcat, with no need to mess with your project dependencies, and works with developer tooling for Tomcat or Tcat. It has a very simple API using annotations. This means iBeans can be plugged into your existing Web apps easily. It includes easy unit and mock testing using JUnit. IBeans Central offers a great place to discover and try new iBeans in your applications.
