NameNotFoundException when looking up datasource jndi from standalone clien

Question

Hi,
I'm trying to lookup datasource jndi from standalone client, but always get exceptions.
I configured an oralce datasource with jndi name "oracleDataSource". When looking it up in servlet, I can get connection.
In order to test it from standalone client, I created following code:
public class DataSourceTest
* Attempt to authenticate the user.
public static void main(String[] args)
String datasource = null;
if (args.length == 1 ) {
datasource = args[0];
System.out.println("datasource = "+datasource);
if(datasource == null)
datasource = "oracleDataSource";
try{
Connection conn = null;
Properties env = new Properties();
env.put("java.naming.factory.initial","com.sun.jndi.cosnaming.CNCtxFactory");
env.put("java.naming.provider.url", "iiop://localhost:3700");
Context initial = new InitialContext(env);
if(datasource != null){
DataSource ds = (DataSource)initial.lookup(datasource);
conn = ds.getConnection();
if(conn != null){
System.out.println("datasource is gotten.");
conn.close();
else
System.out.println("datasource is error.");
System.exit(0);
} catch (Exception ex) {
System.err.println("Caught an unexpected exception!");
ex.printStackTrace();
When running, I get following exception:
[java] datasource = oracleDataSource
[java] Caught an unexpected exception!
[java] javax.naming.NameNotFoundException. Root exception is org.omg.CosNaming.NamingContextPackage.NotFound

I also tried many other methods but always got exceptions. What's wrong with it? How can I lookup the datasource jndi from standalone client?
Thanks in advance!

Thank Tuan!
I tried. When running, the server will read security.properties and ejb.properties. But I didn't use ejb and I didn't know how to configure ejb.properties, so I let ejb.properties empty. The security.properties is as following:
client.sendpassword=true
server.trustedhosts=*
interop.ssl.required=false
interop.authRequired.enabled=false
interop.nameservice.ssl.required=false
The result is:
[java] javax.naming.CommunicationException: Can't find SerialContextProvider
[java] at com.sun.enterprise.naming.SerialContext.getProvider(SerialContext.java:63)

Also, I tried it with ACC. In sun sample ConverterClient.java under rmi-iiop/simple, I added following code under with ACC and without ACC. With ACC, I can get connection. But without ACC, I can't get it.
try{
          DataSource ds = (DataSource)initial.lookup("oracleDataSource");
          Connection conn = ds.getConnection();
          if(conn != null){
          System.out.println("datasource oracleDataSource gotten.");
          conn.close();
          else
          System.out.println("oracleDataSource is error.");
Does it means that we must lookup datasource jndi with ACC?
