How to get the vendor specific jdbc Connection/Statement object in JBoss 4/5

Issue

  • How do I retrieve the vendor specific jdbc Connection/Statement object in JBoss?

  • I want to use Oracle specific oracle.jdbc.driver.OracleConnection and oracle.jdbc.OracleCallableStatement. But I got ClassCastException when I cast the connection object to the vendor specific connection object.

    When I casted to oracle.jdbc.driver.OracleConnection like the following code:

    javax.sql.DataSource ds = (javax.sql.DataSource) (new javax.naming.InitialContext()).lookup("java:OracleDS");
    oracle.jdbc.driver.OracleConnection oracleConn = (oracle.jdbc.driver.OracleConnection) ds.getConnection();
    

    then I got the following ClassCastException:

    java.lang.ClassCastException: org.jboss.resource.adapter.jdbc.jdk6.WrappedConnectionJDK6 cannot be cast to oracle.jdbc.driver.OracleConnection
    

    When I cast to oracle.jdbc.OracleCallableStatement like the following code:

    javax.sql.DataSource ds = (javax.sql.DataSource)  (new javax.naming.InitialContext()).lookup("java:OracleDS");
    java.sql.Connection con = (java.sql.Connection) ds.getConnection();
    oracle.jdbc.OracleCallableStatement oracleStmt = (oracle.jdbc.OracleCallableStatement ) con.prepareCall(sqlstring);
    

    then I got the following ClassCastException:

    java.lang.ClassCastException: org.jboss.resource.adapter.jdbc.jdk6.WrappedCallableStatementJDK6 cannot be cast to oracle.jdbc.OracleCallableStatement
