Siwpas (short for Simple Web Profile Application Server) is a lightweight Java application server platform for developing enterprise quality Web applications with the Java Platform, Enterprise Edition 6 (Java EE 6). Siwpas integrates the Apache Software Foundation's Java EE 6 related projects for providing a Java EE Web Profile compatible runtime platform. Siwpas supports Java EE Web Profile required components. The most important pieces of these components that Siwpas includes are EJB Lite Server (EJB), Java Persistence API (JPA), Java Server Faces (JSF), Context and Dependency Injection (CDI), and Bean Validation (BVAL).
WebMotion is a Web application development framework based on a REST architecture and the Java EE 6 standard. It features a presentation layer management using pages (JSP, HTML, etc.) and REST service exposition (e.g. XHR calls). It enables you to serialize service results into JSON or XML. The framework has deliberately limited capabilities, but it focuses on the ease of use. It leaves open the choice of persistence framework, dependency injection, and validation.
