Seam context problems in a web service
Hi all,
I'm having problems with injection in web service. I think that it is due to context problem but I have no idea how to resolve it.
I'm using Seam 2.0.0.GA and JBoss 4.2.1.GA.
Here is my web service code :
@Stateless
@WebService(name = "Authentication")
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class Authentication implements AuthenticationRemote {
@PersistenceContext
EntityManager em;
@In(create=true)
UserHome userHome;
@In(create=true)
EquipeHome equipeHome;
@WebMethod
public void createUser(int equipeId, String loginName, String password,
String nom, String prenom, String email) {
User newUser = new User();
equipeHome.setEquipeEquipeId(equipeId);
newUser.setEquipe(equipeHome.find());
newUser.setLoginName(loginName);
newUser.setPassword(password);
newUser.setNom(nom);
newUser.setPrenom(prenom);
newUser.setEmail(email);
userHome.setInstance(newUser);
userHome.persist();
}
The UserHome was made by SeamGen. Here is its code :
@Name("userHome")
public class UserHome extends EntityHome<User> {
@In(create = true)
EquipeHome equipeHome;
public void setUserUserId(Integer id) {
setId(id);
}
public Integer getUserUserId() {
return (Integer) getId();
}
@Override
protected User createInstance() {
User user = new User();
return user;
}
public void wire() {
Equipe equipe = equipeHome.getDefinedInstance();
if (equipe != null) {
getInstance().setEquipe(equipe);
}
}
public boolean isWired() {
if (getInstance().getEquipe() == null)
return false;
return true;
}
public User getDefinedInstance() {
return isIdDefined() ? getInstance() : null;
}
}
Here is the error message when I invoke my web service :

When I debugged it, I saw the error happened when I try to set the EquipeId of the equipeHome element.
So, I tried to adopt the way of the Seambay example but I still have an error message.
Here is the new code of the web service :
@Stateless
@WebService(name = "Authentication")
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class Authentication implements AuthenticationRemote {
@PersistenceContext
EntityManager em;
@WebMethod
public void createUser(int equipeId, String loginName, String password,
String nom, String prenom, String email) {
UserBean action = getUserBean();
action.createUser(equipeId, loginName, password, nom, prenom, email);
}
public UserBean getUserBean() {
return (UserBean) Component.getInstance(UserBean.class, true);
}
}
Here is the code of UserBean :
@Name("userBean")
public class UserBean implements Serializable {
@In(create=true)
UserHome userHome;
@In(create=true)
EquipeHome equipeHome;
public void createUser(int equipeId, String loginName, String password,
String nom, String prenom, String email) {
User newUser = new User();
equipeHome.setEquipeEquipeId(equipeId);
newUser.setEquipe(equipeHome.find());
newUser.setLoginName(loginName);
newUser.setPassword(password);
newUser.setNom(nom);
newUser.setPrenom(prenom);
newUser.setEmail(email);
userHome.setInstance(newUser);
userHome.persist();
}
}
User is a simple entity bean.
Here is the error :
