Thank You Dan. Domain Services , it worked :) I was able to implement CURD operations to my Student entity. Now I'm moving in to a domain that is meaningful to Android phones (As You have suggested) to simulate "a public forum" with some threads and posts. And I'm reading [8], [9] to get an idea about Naked objects and RESTful api. If I get any issue regarding that, hope you will help me.
And one thing about DomainObjectContainer: Is it responsible for keeping user information? (I mean session details) [8] http://isis.apache.org/learning-more/resources/Pawson-Naked-Objects-thesis.pdf [9] http://www.infoq.com/articles/Intro_Restful_Objects On Wed, Apr 10, 2013 at 5:44 AM, Dan Haywood <d...@haywood-associates.co.uk> wrote: > > > On 10 April 2013 13:15, DImuthu Upeksha <dimuthu.upeks...@gmail.com> wrote: >> >> >> 1.
