jakarta-ee - EJB がコードからの JDBC DataSource res-ref のルックアップに失敗する

Question

jBoss EAP 6.[3,4] で自動起動 EJB をテストしましたが、デプロイメント記述子で定義された JDBC リソース ref のルックアップに失敗し、例外が発生しました。

EAR にパッケージ化された AutoStart EJB は次のようになります。

@Singleton  
@Startup  
public class ExtractStartupBean implements SessionBean {    
     @PostConstruct  
    public void initialize() {  

          try {  
               InitialContext context = new InitialContext();  
               DataSource ds = (DataSource) context.lookup("java:comp/env/jdbc/MyDS");  
               Connection conn = ds.getConnection();  
               System.out.println("JDBC Client Info : " + conn.getClientInfo());  
          } catch (Exception e) {  
               throw new RuntimeException(e);  
          }  
     }  

     @PreDestroy  
     public void terminate() {  
          // Do something....Not important right now...  
     }  
}

興味深い事実は、デプロイメントが正常に機能することです...つまり、私の EJB はエラーなしで正常にデプロイされます。これは、jBoss Application Server が DataSource java:/jdbc/myDS を正常に検出したことを意味しますが、自動開始コードで同じものにアクセスしようとするとそれは失敗します！また、ここに追加するだけで、JNDI を直接検索すると (WebSphere や WebLogic では動作しないため望ましくありません)、リソースは OK であることがわかります。

私はこれを他の JCA リソースで何度も行ってきましたが、問題に直面したことはありません。

あなたの EJBはでsession-typeはありません。StatelessSingleton

<ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" version="3.1"

              <res-type>javax.sql.DataSource</res-type>  
              <res-auth>Container</res-auth>  
          </resource-ref>  
      </session>  
  </enterprise-beans>  
</ejb-jar>

さらに、ejb 名を一致させる必要があります。

@Singleton(name="DFExtractor")
@Startup  
public class ExtractStartupBean implements SessionBean {

とはいえ、次のように追加すると:

@Resource(name="jdbc/myDS")
private DataSource ds;

EJB に追加すると、ejb-jar.xml ファイルはまったく必要なくなります。JNDI リソースを移植可能にマッピングするために jboss-ejb3.xml を引き続き使用できます。
