Attempted to use a 5.0 DataSource outside of a 2.3 servlet

Question

I am using WAS 5.0 with Oracle 9.2 . I cannot get a servlet to work with the datasource 5.0 . Any ideas??
The message I get is :

Context implementation: com.ibm.ws.naming.jndicos.CNContextImpl
Context method: lookup
Context name: localhost/nodes/localhost/servers/server1
Target name: jdbc/WMBDatasource
Other data:

     at com.ibm.ws.naming.jndicos.CNContextImpl.lookup(CNContextImpl.java:1179)
My Servlet code is :

                                             throws ServletException, IOException
     javax.sql.DataSource ds = null;
     java.sql.Connection con = null;
     java.io.PrintWriter out = resp.getWriter();
     resp.setContentType("text/html");
     try
     out.println("Looking up DataSource<br>");
     javax.naming.InitialContext ctx = new javax.naming.InitialContext();
     ds = (javax.sql.DataSource) ctx.lookup("jdbc/WMBDatasource");
     out.println("Getting connection<br>");
     con = ds.getConnection();
     con.close();
