WildFlyDataSourceはjavax.naming.Contextにキャストできません

Question

JDBC接続を作成するために、データソースから接続パラメータを読み取ろうとしています。しかし、私は例外[1]

イムのような試みてwildfly 10.xの

イムを使用して、次の取得します。

Context initCtx = new InitialContext(); 
Context envCtx = (Context) initCtx.lookup("java:jboss/datasources/myDS"); 

// Look up our data source 
DataSource ds = (DataSource) 
envCtx.lookup("java:/testdb"); 

誰でも私を助けることができますか？

エラーがスタックトレースの1行目に記載されています。

java.lang.ClassCastException: org.jboss.as.connector.subsystems.datasources.WildFlyDataSource cannot be cast to javax.naming.Context 

あなたはjavax.sql.DataSource上で検索を行うと、javax.naming.Contextにキャストしようとしています。
