[JBoss-user] [JNDI/Naming/Network] - ClassCastException at $Proxy2.getTables()
I've configed JBoss Connection Pool and the database is Oracle9i.
But I met some error when I use getTables() method,there was an error. The code
is as followed:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "localhost:1099");
InitialContext ctx = new InitialContext(env);
DataSource ds = (DataSource) ctx.lookup("OracleDS");
try {
Connection conn = ds.getConnection();
DatabaseMetaData dm = conn.getMetaData();
System.out.println(dm.getDriverName());
System.out.println(dm.getDriverVersion());
System.out.println(dm.usesLocalFiles());
Object o= dm.getTables(null, null, "%", null);
conn.close();
} catch (SQLException e1) {
e1.printStackTrace();
}
} catch (NamingException e) {
e.printStackTrace();
}
The error message was:
java.lang.ClassCastException
at $Proxy2.getTables(Unknown Source)
at testH.main(testH.java:43)
Exception in thread "main"
I'm confused, anyone can help me? Thanks in advance!
JBoss 4.0.1sp1, Oracle9i
