TOMCAT6.0连接池连接sqlserver(解决Cannot createJDBC driver of class for connect URL'null
用tomcat6.0连接池和hibernate3.2+spring2.5连接数据库时出现以下异常:

望高手帮们解决:
jsp页面为:
<%@ page language="java" pageEncoding="utf-8"%> 

<%@ page import="java.sql.*"%> 

<%@ page import="javax.sql.*"%> 

<%@ page import="javax.naming.*"%> 

<html> 

<head> 

<title>Test of Tomcat connection pool</title> 

</head> 

<body> 

<% 

out.print("strat test connection pool!<br/>"); 

try{ 

 Context initCtx = new InitialContext(); 

 Context ctx = (Context) initCtx.lookup("java:comp/env/"); 

 Object obj = (Object) ctx.lookup("jdbc/Hotel"); 

 DataSource ds = (javax.sql.DataSource)obj; 

 Connection conn = ds.getConnection(); 

 out.print("tomcat sqlserver connection pool runs perfectly!"); 

 conn.close(); 



catch(Exception ex){ 

 out.print(ex.getMessage()); 

 ex.printStackTrace(); 



%> 

</body> 

</html> 

页面输出为:
strat test connection pool!
Cannot create JDBC driver of class '' for connect URL 'null'
