XINS is a technology used to define, create, and invoke remote APIs. XINS is specification-oriented. When API specifications are written (in XML), XINS will transform them to HTML-based documentation and Java code for both the client-side and the server-side. The communication is based on HTTP. XINS competes with the complex SOAP technology. Main design goals include simplicity, scalability, and testability. XINS is not only a specification technology, but also an application development framework. It offers transaction logging, unique log documentation, and active code generation.
Restlet is a REST framework for Java. It supports all REST concepts (Resource, Representation, Connector, Component, etc.) and is suitable for both client and server Web applications. It supports major Web standards like HTTP, SMTP, XML, JSON, WADL, and Atom.

Azzyzt JEE Tools is a set of Eclipse plugins for creating a so-called "azzyzted" project, and for creating code from a model. Azzyzt uses Java JPA entities as a model, and from that model it creates an enterprise application, ready to be deployed in a Java EE 6 application server like GlassFish 3.1, ready to be accessed via CORBA, SOAP, and REST. Thus the generated application is a set of Web services, providing all that you need in a typical CRUD application. Generated enterprise applications have separate source folders for generated and developer-supplied content. You can add your own functionality to a well-engineered base project. Azzyzt JEE Tools is not about user interfaces. It is expected that the generated application is accessed by a RIA frontend or by a fat client.
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.
