I am trying to set up a seam project that uses EJB3 annotations on the entities
, JSF for the views, and Hibernate as the persistence manager (Hibernate
Sessions).
I am able to compile and deploy without errors; I am even able to invoke pages
in my app without exceptions. However, it does not seem that Seam is doing
what I expect (possibly I have misconfigured something).
What I am trying to do is create the skeleton of a simple login process. I
have provided here, the User entity, and the SimpleLogin POJO I created to
perform the login process:
@Entity
| @Table(name="user",
| uniqueConstraints = [EMAIL PROTECTED](columnNames={"a_number"})}
| )
| @EntityListeners(BaseEntity.class)
| @Name("user")
| @Scope(ScopeType.SESSION)
| public class User extends BaseEntity implements Serializable {
|
| private final Log log = LogFactory.getLog(User.class);
|
| private static final long serialVersionUID = -795127549881852884L;
|
| private String aNumber;
| private Set<Link> links;
|
| public User() { log.info("new User()"); }
|
| @Column(name = "a_number",unique =
true,insertable=true,nullable=false,updatable=false,length=12)
| public String getaNumber() { return aNumber; }
| public void setaNumber(String aNumber) { this.aNumber = aNumber;
log.info("User.setaNumber("+aNumber+")"); }
|
| @OneToMany(cascade= CascadeType.ALL, mappedBy="user", fetch =
FetchType.EAGER)
| public Set<Link> getLinks() { return links; }
| public void setLinks(Set<Link> links) { this.links = links; }
|
| }
|
and here is the SimpleLogin POJO:
@Name(value = "simpleLogin")
| @Scope(ScopeType.EVENT)
| public class SimpleLogin {
|
| @In(required = true) @Out
| private User user;
|
| @In(create=true)
| private Session appssoDB;
|
| @In(create=true)
| private FacesMessages facesMessages;
|
| public String login() {
| final User u = (User)appssoDB.createQuery("from User where
aNumber=:aNumber")
| .setParameter("aNumber",user.getaNumber())
| .uniqueResult();
| if (user == null) {
| facesMessages.add("Invalid A Number");
| return "login";
| } else {
| return "loggedIn";
| }
| }
| }
|
now here is a page that I borrowed from one of the Seam examples and adapted to
use these beans:
<h:form>
| <div id="document">
| <div id="container">
| <div id="sidebar">
| <fieldset>
| <div>
| <h:outputLabel for="username">Login
Name</h:outputLabel>
| <h:inputText id="username"
value="#{user.aNumber}" style="width: 175px;" />
| </div>
| <div class="errors"><h:messages
globalOnly="true"/></div>
| <div class="buttonBox"><h:commandButton
action="#{simpleLogin.login}" value="Account Login" class="button" /></div>
| <div class="notes"><h:commandLink
action="register">Register User</h:commandLink> | Ask for Help</div>
| </fieldset>
| </div>
| <div id="footer">Created with JBoss Seam, Facelets, and JSF 1.1.01 Ref.
Impl.</div>
| </div>
| </div>
| </h:form>
| <ui:debug hotkey="D"/>
| #{conversation.id}
|
When I deploy the app, I get the following (relevant snippets?) in the server
console:
| 11:19:32,743 INFO [ServletContextListener] Welcome to Seam 1.0 rc1
| 11:19:32,758 INFO [Initialization] initializing Seam
| ...
| ...
| ...
| 11:19:35,868 INFO [User] new User()

| 11:19:36,055 INFO [SessionFactoryObjectFactory] Bound factory to JNDI

| ...
| ...
|
There are no exceptions in the deployment and it appears from the lines above
that Seam is started and hibernate is aware of my User class.
So I invoke my main.seam page.. everthing displays 'just fine' no exceptions -
I get conversation.id = 1, which I take to mean that seam is participating in
the request processing successfully. Here is the server.log contents that I
see when I invoke main.seam

When I look at the server console for both requests - I see no indication that
a new User class has been created and that it's setaNumber() method has been
invoked. I studied the example code and the seam documentation carefully
w.r.t. setting up a Seam application for Hibernate in a Java EE environment -
nothing stands out. I am using JBoss 4.0.4.CR2 with EJB installed.
Any help in understanding why my named components are not being 'associated'
with the page is appreciated.
Thanks.
