两点疑问：
1 你的测试代码是在jboss中运行还是客户端程序？如果是客户端程序，这样获取数据库连接肯定是不正确的。
2 test.getInitialContext()的代码是什么，如果连接到远程的jboss，肯定也是不行的。

数据库连接不同于EJB组件，客户端程序去引用数据库连接，肯定是不行的，这个连接池只能为容器所用。

package testejb;

import javax.naming.*;
import java.util.Hashtable;
import javax.rmi.PortableRemoteObject;
import javax.ejb.EJBMetaData;
import javax.ejb.HomeHandle;
import javax.ejb.Handle;

public class MyTestClient
{
  public MyTestClient()
  {
  }

  private Context getInitialContext() throws NamingException
  {
    Hashtable environment = new Hashtable();

    environment.put(Context.INITIAL_CONTEXT_FACTORY,
                    "org.jnp.interfaces.NamingContextFactory");
    environment.put(Context.URL_PKG_PREFIXES,
                    "org.jboss.naming:org.jnp.interfaces");
    environment.put(Context.PROVIDER_URL, "jnp://localhost:1099");

    return new InitialContext(environment);
  }

  public static void main(String[] args)
  {
    MyTestClient test = new MyTestClient();
    try
    {
      Context context = test.getInitialContext();
      Object ref = context.lookup("java:/OracleDS");
      java.sql.Connection con = ( (javax.sql.DataSource) ref).getConnection();

    }
    catch (Exception ex)
    {
      System.out.println(ex.getMessage());
    }
  }

}
