Thanks for reply.
I am a bit confused now. Would you please give a bit more explain on how to
add make AccountDAO a service?
Why I am confused is because I discover when I switch back using the old
testing code, it works correctly. The way how I obtain the AccountDAO is
in Login.java
@Inject
private IAuthService auth;
Object onSubmitFromLogin(){
...
user = auth.authenticate(new User("-1", this.account, "",
this.password));
...
}
in AppModule.java
public static void bind(ServiceBinder binder) {
binder.bind(IAuthService.class, AuthService.class);
binder.bind(IAccount.class, Account.class);
}
in AuthService.java
@Inject
private IAccount accountDAO;
public User authenticate(User user){
...
User u = accountDAO.findUserByAccount(account);
...
}
Then when accessing the login page from web, everything works fine (the
accountDAO is not null).
But when switching using one that integrates JAAS then the accountDAO
becomes null. For instance, in AuthService.java the code switch to use
RdbmsLogin.java where injecting accountDAO (@Inject private IAccountDAO)
in AutheService.java
public User authenticate(User user){
...
RdbmsCallbackHandler handler =
new RdbmsCallbackHandler(account, password);
try{
LoginContext context =
new LoginContext(JAAS_REALM, handler);
context.login();
}catch(LoginException le){
le.printStackTrace();
}
...
}
in RdbmsLogin.java
public class RdbmsLogin implements LoginModule{
public boolean login() throws LoginException {
...
flag = validate(account, password);
...
}
private boolean validate(String account, String password){
...
// the accountDAO is always null here, but the accountDAO
injected inside
the AuthService is not null.
User user = accountDAO.findUserByAccount(new User("-1",
account, "",
password));
...
}
Or if I simply replace AuthService with RdbmsLogin, the AccountDAO injected
inside RdbmsLogin is still null.
What additional setting I need to configure?
Thanks for patiently answering my questions.
I appreciate it.
