Statement st=null;
ResultSet rs=null;
res.setContentType("text/html");
java.io.PrintWriter out = res.getWriter();
String tcnt=null;
try {

Context cx = new InitialContext();
DataSource ds = (DataSource)cx.lookup("oradsn");
out.println("the DataSource is :"+ds);
con=ds.getConnection();

how did you configure your connection pool ? (see your config.xml : maybe you set a size 0 for your connection pool)
