c3p0连接数据库失败No suitable driver

c3p0连接SQL 2005数据库报错No suitable driver,是url错误导致
这是jdbc连接数据库时配置
drivers=com.microsoft.sqlserver.jdbc.SQLServerDriver
url=jdbc:sqlserver://localhost:1434;DatabaseName\=db_news2
这是c3p0连接数据库配置
dataSource.setJdbcUrl( “jdbc:sqlserver://localhost:1434; DatabaseName=db_news2”);
dataSource.setDriverClass( “com.microsoft.sqlserver.jdbc.SQLServerDriver”);
其中url不同
