I can inject with seam as it seems
My user class
|
| @Entity
| @Table(name="USERS")
| @Name("user")
| @Scope(SESSION)
| public class User implements Serializable
| {
| private String username;
| private String password;
| private String name;
|
| public User(String name, String password, String username)
| {
| this.name = name;
| this.password = password;
| this.username = username;
| }
|
| public User() {}
|
| @NotNull
| @Length(max=100)
| public String getName()
| {
| return name;
| }
| public void setName(String name)
| {
| this.name = name;
| }
|
| @NotNull
| @Length(min=5, max=15)
| public String getPassword()
| {
| return password;
| }
| public void setPassword(String password)
| {
| this.password = password;
| }
|
| @Id
| @Length(min=5, max=15)
| @Pattern(regex="^\\w*$", message="not a valid username")
| public String getUsername()
| {
| return username;
| }
| public void setUsername(String username)
| {
| this.username = username;
| }
|
| public String toString()
| {
| return "User(" + username + ")";
| }
| }
|
|
My registerAction class
| @Stateful
|
| @Scope(EVENT)
|
| @Name("register")
|
| public class RegisterAction implements Register
|
| {
|
|
|
| @In(create = true)
|
| private User user;
|
|
|
| @PersistenceContext
|
| private EntityManager em;
|
|
|
| @In(create=true)
|
| private transient FacesMessages facesMessages;
|
|
|
| private String verify;
|
|
|
| public String register()
|
| {
|
|
|
|
|
|
|
| if ( user.getPassword().equals("hi") )
|
| {
|
| List existing = em.createQuery("select username from User where username=:username")
|
| .setParameter("username", user.getUsername())
|
| .getResultList();
|
| if (existing.size()==0)
|
| {
|
| em.persist(user);
|
| facesMessages.add("Successfully registered as #{user.username}");
|
| return "/registered.xhtml";
|
| }
|
| else
|
| {
|
| facesMessages.add("Username #{user.username} already exists");
|
| return null;
|
| }
|
| }
|
| else
|
| {
|
| facesMessages.add("verify", "Re-enter your password");
|
| verify=null;
|
| return null;
|
| }
|
| }
|
|
|
| public String getVerify()
|
| {
|
| return verify;
|
| }
|
|
|
| public void setVerify(String verify)
|
| {
|
| this.verify = verify;
|
| }
|
|
|
| @Destroy @Remove
|
| public void destroy() {}
|
| }
|
|
and my xhtml page
| <h:form id="testForm">
| <s:validateAll>
| <h:inputText value="#{user.username}" />
| <h:inputText value="#{user.password}" />
| <h:inputText value="#{user.name}" />
| <h:commandButton value="Submit" action="#{register.register}" />
| </s:validateAll>
| <h:messages />
| </h:form>
|
|
my problem is that I get this exception
