Learning Apache Ofbiz?

i am a java developer, i have just started learning apache ofbiz,an open source enterprise automation software,i went through the tutorials on official apache ofbiz site,as ERP is a big thing in itself, this takes time to learn.

the question would sounds like asked by a novice, still, can anyone suggest what should be the proper flow (OR say better approach) for learning Ofbiz efficiently, like from where should i start,i mean sequence of topics i should start with or the prerequisities?

link to some example explaining basics will be great!!

What is OFBiz framework?

OFBiz is a Java based web framework including an entity engine, a service engine and a widget based UI allowing you to quickly prototype and develop your web application. CRM & ERP.

You learn it base on what you want to use it for. Ofbiz is not to be used out of box. You need to customize it a bit to fit your needs. Customization doesn't mean programming, but making use of the modules you need. So the first question is what do you want to use it for. And move from there.

Good luck.
