They should go into a service or a repository or whatever data access pattern is suitable for the context. This is where we lack any standardization at the moment, and it would be better to not limit this exercise to improving the conventions alone, but also the architecture. Vineet, this is the topic I'm writing about at the moment. To be honest, I quite like to have persistent concerns in JSF beans and REST for certain projects... but not all, and that's where I thing Forge should give some choices. What I'm writing is about having 3 different architectural styles that could be resume like this (using CLI) : Current (generates JSF/REST from entities) : jsf-scaffold-from-entity rest-scaffold-from-entity EJB Centric (add a service layer to deal with persistence) : ejb-scaffold-from-entity jsf-scaffold-from-ejb rest-scaffold-from-ejb REST centric (the JSF backing beans use the REST endpoint, using JAX-RS 2.0 Client API) : rest-scaffold-from-entity jsf-scaffold-from-rest

Hi Vineet, I've published the blog : http://antoniogoncalves .org/2013/10/29/several-architectural-styles-with-java-ee-7/ I've implemented the three different architectural styles and you can have a look at : https://github.com/agoncal/agoncal-sample-javaee /tree/master/03-TierArchitecture Unfortunately I still have an issue with the RESTendpoint doing a paginate (I've asked some help in the jersey mailing list, but still no news, you can have a look at : https://java.net/projects/jersey/lists/users/archive/2013-10/message/64 If you look at the code for the three styles, there are not many changes. I would hope that Forge could help developers to generate different architectural styles. As I said, we could do something like this (depending on the future syntax : https://issues.jboss.org/browse/FORGE-944) * Horizontal :* - jpa-scaffold-from-database - jsf-scaffold-from-entity - rest-scaffold-from-entity *EJB Centric :* - jpa-scaffold-from-database - ejb-scaffold-from-entity - jsf-scaffold-from-ejb - rest-scaffold-from-ejb *REST centric :* - jpa-scaffold-from-database - rest-scaffold-from-entity - jsf-scaffold-from-rest If that interests you, I would be more than happy to contribute to something like that.

Cool, I would be more than happy to contribute to that. PS : @lincoln BTW, I've updated the JIRA related to the CLI syntax with what you've just said : https://issues.jboss.org/browse/FORGE-944?focusedCommentId=12825594&p... 2013/10/29 Lincoln Baxter, III <lincolnbaxter(a)gmail.com&gt; Hey Antonio! > > I'm definitely very interested in seeing more styles of programming > supported!
