アルフレコで次のコードを正しく動作させるにはどうすればいいですか？

メールアドレスのユーザー名とランダムなパスワードを生成するために、AlfrescoのCreateUserHandlerという名前でクラスを作成しました。これはおそらくですアルフレコで次のコードを正しく動作させるにはどうすればいいですか？

         } 
       } 




}

を誰かがこれで私を助けてthis..Pleaseで例外を取得しています

private ServiceRegistry getServiceRegistry() { 
     // TODO Auto-generated method stub 
     return null; 
    }

と

private PersonService personService = getServiceRegistry() 
      .getPersonService();

の0

その結果、NPEがスローされます。 getServiceRegistry()は常にnullを返す場合

私はそれを公開するか保護しますか？どのような変更を行う必要がありますか？ – APM

ただ削除してください。あなたは、あなたがxml構成でそのオブジェクトを注入したと仮定して、それを必要としません。ちょうどserviceRegistryを使用してください – zawhtut

私はまだnullポインタの例外を取得しています。誰かがフォーマットされたコードで私を助けることができます – APM

この

private NodeService nodeService = getServiceRegistry().getNodeService();

は動作しません。

最も簡単な方法はpersonService、actionService、およびsearchServiceために同じことを行いメンバーnodeServiceを削除し、

String address = (String) serviceRegistry.getNodeService().getProperty(person, ContentModel.PROP_EMAIL);

に

String address = (String) nodeService.getProperty(person, ContentModel.PROP_EMAIL);

ような行を変更することです。
