How to run Liferay on Resin Professional
Intro
Liferay is an awesome platform on which to build your website. It comes with TONS of functionality out of the box; pages, wiki, blog, forum, calendar, polls, messaging, social integration, mobile device optimization, etc.
Liferay really likes to "take over" your Resin server. It integrates Resin like a component of Liferay, rather than Liferay being an application that runs in Resin... Unfortunately this means that it appears to duplicate or invalidate some of Resin Pro's advanced features like clustering and failover... (I'm still learning Liferay and will post more about scaling and high-availability later.)
