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.
