JDBC (URGENT): Can only bind References or Referenceable objects

I want urgent help to understand how I can use a JDBC data source with SAPDB.

I am trying to bind a SAPDB data source (class DataSourceSapDB) to File System JNDI Context.

This is my code - standard Java code for binding:

package com.ess.shared.util.db.dsRegistration;

import java.util.Hashtable;

import javax.naming.Context;

import javax.naming.InitialContext;

import javax.sql.DataSource;

import com.sap.dbtech.jdbcext.*;

public class SapDB {

static public void main(String [] args)

throws Exception

{

DataSourceSapDB ds;

Context ctx;

Hashtable env = new Hashtable();

env.put(Context.INITIAL_CONTEXT_FACTORY,

"com.sun.jndi.fscontext.RefFSContextFactory");

ctx = new InitialContext(env);

System.out.println("Context is: " + ctx);

ds = new DataSourceSapDB();

System.out.println("DataSource is: " + ds);

//ds.setServerName("Vin");

ds.setUrl("jdbc:sapdb://localhost/SAPAMSDB?trace=e:\\sapdbLocal.log");

//ds.setPort(3306);

//ds.setDatabaseName("DBAMSDB");

ds.setUser("scott");

ds.setPassword("tiger");

ctx.bind("java:/AMSDB_SAP_LOCAL", ds);

ctx.close();

}

I get the following exception:

Context is: javax.naming.InitialContext@74a24a

DataSource is: com.sap.dbtech.jdbcext.ConnectionPoolDataSourceSapDB@360be0

javax.naming.OperationNotSupportedException: Can only bind References or Referenceable objects
