C3P0数据源在spring启动报错

我用c3p0连接sybase数据库，结果c3p0报错了，错误如下：

请问这是错误在哪里呢？

  1.   

    额 把charset换成cp850  jdbc:jtds:sybase://192.168.0.63:5000/test;charset=cp850  反正两个字符集一样就行了
      

  2.   

    用cp850不行啊，查出的中文会有乱码，我原来用charset=eucgb时在dbcp下没报错，直接用jdbc的方式也没报错，但是到了c3p0下就报错，请问这是什么问题呢？
      

  3.   

    那就还用dbcp吧，不要听网上说的什么dbcp bug多，只要配置好了，没什么问题的。
