[jboss-user] [JBoss Seam] - desing pattern for remote accessing

Hello, I am looking for correct design pattern which will allow me to access data via EJB remotly. I want to have a single point of enterance both for SEAM application and for other applications, which use the same data. My current idea is to have: - Stateless EJB acting as a DAO - Stateful EJB, acting as a seam action - JSF as a presentation layer The stateful EJB calls the stateless to get the data. It also additionally has a remote interface which allows other application to call it. Due to convetions of seam I have to "double" the interface, for example: | @DataModel | private List<Contact> contacts; | | @DataModelSelection | private Contact contact; | | @Factory("contacts") | public void findAll() { | if(contacts == null) { | contacts = myStatelessBean.findAll(); | } | } | | public List<Contact> getContacts() { | findAll(); | return contacts; | } | I find this sollution quite innatural, because you have to implement two interfaces, which do quite the same thing. The other idea is to develop a facade, but it introduces another problem: passing parameters and returning values - it is done by @In and @Out annotations in seam. You will have to call additional methods from facade to set parameters and get the returning values. Which sollution is better? Maybe you know a better sollution for this problem? thx View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4049184#...
