配置proxool不能实例化ProxoolConnectionProvider问题的解决

配置proxool，加载了proxool的包，一直报错，看错误提示，说不能实例化ProxoolConnectionProvider，查hibernate核心包，里面connection里确实没有这个东东，后来才知道要加载一个hibernate-proxool包才行，可所有配置的教程都没提过，是不是这是该默认知道的东西，我了解的东西太少了？

在maven里加入这个包的最新版本4.1，却发现还是不行，解包一看，4.1里面ProxoolConnectionProvider的pakage路径换了，再晕，这也没事换换啊。因为前面的东西有基于hibernate 3.5.1的，干脆换成3.5.1版本，OK了。

 

现在将我的spring+struts+jpa(hibernate)+proxool的配置文件贴出来，希望对大家有用，不过目前我的配置会报一个jndi找不到路径名的警告，但不影响运行，这个问题还待解决，见我博客上一篇文章，求解答啊：http://blog.csdn.net/yyzhq/article/details/7484620
