I was unsuccessfuly looking for some decent, neither too simple nor to complex Java web application for Iterate hackaton “War of Web Frameworks”. I want to record the demo apps and options I’ve found in the case I’ll need it ever again. Tips are welcome.

• Hibernate CaveatEmptor – 2006, no UI, richer domain model (+- 15), auction site, created for the book Hibernate in Action, uses EJB3
• EclipseLink Distributed Collatz Solver – 2011, 6 entities, JPA 2.0, EJB 3.1, JSF 2.0, JAX-RS, intended to test distribution and JPA behavior under load, primitive UI, computation-intensive app (multiple SE clients + 1 EE server)
• Alfresco CMS – stable, complex application with REST API (CMIS compatible) based on its “web scripts”
• NetBeans Samples including 1-entity Pet Catalog – usually too primitive (1-few classes, ..)
• Spring samples (svn) – including jpetstore (5 DAOs, Struts & S. MVC UI), petcare, petclinic[-groovy], spring-mvc-showcase; another example is Spring Greenhouse (a Spring reference app., “App Catalog that allows Developers to develop new client apps for which users may establish Account->App connections”), the functionality of the UI seems to be quite primitive
  • PS: I had to fix JPetStore’s pom.xml to build it
• Demos of JSF component libraries (RchFaces, PrimeFaces, …) – likely tightly coupled to JSF
• A. Bien’s x-ray project – minimal UI, developed for the book “Real World Night Hacks”
• Pebble Blog – lot of files and servlets even though the use cases are quite simple (post blog, view posts, ..)
