Hi, all:

      I try to use DatabaseMetaData to get all tables and views from a Oracle database. But exception is thrown at the red line. You can see that I look up a remote DataSource and get connection from the data source. But if I use DriverManager.getConnection(url, user, pwd) way to get connection. This issue does not exist. I can get all the tables and views successfully…

      Any help from you will be much appreciated!

public class Test {

    public static void main(String[] args) throws Exception {

        Properties props = new Properties();

        props.put(Context.PROVIDER_URL, "jnp://10.111.3.161:1099");

        props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");

        Context ctx = new InitialContext(props);

        DataSource ds = (DataSource)ctx.lookup("OracleDS");

        Connection conn = ds.getConnection();

        DatabaseMetaData dbmd = conn.getMetaData();

        ResultSet rs = dbmd.getTables(null, "%", "%", new String[] { "TABLE", "VIEW" });

    }

}

      Exception:

       Exception in thread "main" java.lang.ClassCastException: $Proxy3
