I'm finding from the existing solutions the open source calendar portlet (the servlet implementation would also be fine). Main requirement is the ability to store in DB events scheduled by different users.
Could anybody recommend any proven solution?
Liferay portals use much liferay-specific code - so the embedding of such code to the existing application would be rather difficult. The gems project looks like is no longer being supported. Synex in not the open source portlet reposiory.
Desirable that it would use hibernate for persistence and struts for view layer.
