Cannot create PoolableConnectionFactory错误
刚开始用myeclipse+tomcat开发项目，运行的时候出现Cannot create PoolableConnectionFactory(Connection refused )的错误提示。把本机和服务器的防火墙都关了还是一样。但本机通过toad等工具能连这个oracle服务器，telnet服务器ip也通。应该不是程序代码的问题，因为把整个WEB-INF目录打包发给几个同事，在他们的电脑上面运行都没有问题。估计是myeclipse或windows环境变量的问题，但查不出具体问题在什么地方。
出错信息如下：

顶起 --------------------编程问答-------------------- 有客户端，不然也不能用toad了。 --------------------编程问答-------------------- 我把原来的ojdbc6.jar换为ojdbc14.jar就可以了，好奇怪。看了说明，ojdbc14.jar是for jdk1.4和1.5，ojdbc6.jar是for jdk1.6的。而我和同事都安装的jdk1.6，他们可以用ojdbc6.jar，但我只能用ojdbc14.jar。
会不会因为操作系统的问题，我是xp，他们是win7？ --------------------编程问答--------------------
不明白，程序链接oracle,为什么非要安装oracle客户端.
补充：Java , Java EE
