[keycloak-user] Programmatically login as a user

[valsaraj pv]

I tried following code:

> loginContext = new LoginContext("keycloak", new CallbackHandler() {
>      @Override
> public void handle(Callback[] callbacks) {
> int len = callbacks.length;
> Callback cb;
> for (int i = 0; i < len; i++) {
>      cb = callbacks[i];
>      if (cb instanceof NameCallback) {
> NameCallback ncb = (NameCallback) cb;
> ncb.setName(mdbuserName);
>      } else if (cb instanceof PasswordCallback) {
> PasswordCallback pcb = (PasswordCallback) cb;
> pcb.setPassword(mdbUsrPass);
>      }
> }
>      }
>  });
>  loginContext.login();


For following dependency issue while trying to login:

> *[Server:app-node-00] unable to find LoginModule class:
> org.keycloak.adapters.jboss.KeycloakLoginModule from [Module
> "deployment.app.ear.appEJB.jar:main" from Service Module Loader] at
