[jboss-user] [JBoss Seam] - Component Architecture instead of traditional Layers

Hi, I have searched this forum but did not found answers to my questions regarding architectural patterns (pro/cons). The examples are to simple for my taste. Coming from the traditional J2EE pattern oriented software development with Session Facades, DTO's, DAO's, ServiceLocator I dream a bit from a simplified architecture and I hope this becomes true. What I want to do: I have a dozen of losely coupled seam components (session beans) which are the foundation of my application besides the entity beans. For example, I have a customer component which provides services for customers like load current logged in customer, change the customers personal data. Then I have another computer component which manages the computer infrastructure of a customer like adding a computer, add RAM to the computer. But this computer needs a customer to manage its computer items. I like to inject into the computer component the customer component. I hope this is enough to describe my architecture - SOA like. Are there problems to expect with this architecture like | a) Injecting stateful session beans into other stateful session beans? | | b) Are there any problems regarding the different seam scopes like CONVERSATION and long running CONVERSTAION scopes beans? | | c) Any patterns to avoid or seam annotations like @Create or @Factory? | | | If you can share any insights into your experience whould be very helpful. I am breaking my head philosophize about component architectures with seam or using seam components with a DAO-Layer and Entity Beans. In the near future, there is probably another client (Netbeans RCP) than JSF/Facelets. | | | Regards, | | Cyrill View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4121437#...
