difference between "applications" folder and the "hot-deploy" folders in ofbiz?

I'm new to ofbiz. I create an application in my "ofbiz/hot-deploy" folder. In some site, books they mention our application should be present in "applications" folders also. But I don't know the difference between put user defined applications in the folders namely "hot-deploy" and "applications" in ofbiz.

Please tell the difference, because it will be very useful to my project. Please forgive my mistakes in my questions because I'm new to ofbiz .

Thanks &am开发者_如何学JAVAp; Regards, Sivakumar.J

applications is where the OOTB apps provided with the OFBiz framework like marekting, order, party reside. It is best NOT to put your stuff there so you can forward integrate with the next version of Ofbiz.

application components: they are generic applications that can be used as they are or extended/customized (product, order, party, manufacturing, accounting etc…); application components have access to the services and tools provided by the framework components and to the services published by other application components

hot-deploy is where you put your custom application which also has access to the services underlying from the framework.

So if you make a new application say SivakumarWebApp then place it in the hot-deploy, and it can access the framework components as well as other application components.
