Java EE real world open source applications [closed]

Question

What are good Java EE real world (not like learning projects like PetStore) open source applications? In particular I'm looking for examples of using ORM (JPA-Hibernate), Spring (IoC, transaction managment, security) in a real world environment

ps a good example what I'm looking for - ASP.NET starter applications (for .net platform)

Answer 1

Alfresco uses Spring/Hibernate. I believe OpenNMS does as well.

Answer 2

The Java EE 6 homepage has several samples: Java EE 6 Sample Applications. Further there's the Appfuse which gives you the possibility to compose a kickoff Java EE application together yourself.

Update: I realize that you're rather looking for an overview of all "3rd party" open source Java EE based ecommerce/business/CMS systems. You can find pretty complete overviews at Java-Source.net. For example all ERP-CRM systems and CMS systems.
