Working example

DEPRECATED! This page has not been updated for a long time. Still, it may contain some valid and valuable information.

Let's modify our webapp example. Instead of passing the name, we will pass the user id, then find it in the database, and print it in the jsp.

Action

    @MadvocAction
    public class IndexAction {

        @PetiteInject
        FooService fooService;

        @In
        Long id;

        @Out
        User user;

        @Action
        public void view() {
            if (id != null) {
                user = fooService.findUserById(id);
                System.out.println(user);
            }
        }
    }

JSP

    <html>
    <head>
        <title>Jodd</title>
        </head>
    <body>
    ...hello ${user.name}...
    </body>
    </html>

Service

    @PetiteBean
    public class FooService {

        @PetiteInject
        AppDao appDao;

        @Transaction(propagation = PROPAGATION_SUPPORTS, readOnly = false)
        public void storeUser(User user) {
            appDao.store(user);
        }

        @Transaction(propagation = PROPAGATION_SUPPORTS)
        public User findUserById(long id) {
            return appDao.findById(User.class, Long.valueOf(id));
        }
    }

This tutorial ends here, but it is just a beginning for your quest through Jodd! Enjoy!
