Fail to get tables by a remote Datasource deployed in JBOSS

[poweryoung]

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

at $Proxy2.getTables(Unknown Source)

at Test.main(Test.java:62)

Sorry, the "red line" should be:

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