根本就找不到你的路径
你看看你的jar和你的数据库连接池的配置

[feixiangclf]

数据库连接池的配置有问题

[SLOONG]

Caused by: java.sql.SQLException: No suitable driver
没找到相应的数据库驱动

[/Quote]同意哈

[zhoulijian]

没有合适的驱动程序包吧？譬如mysql、sql Server、jdb等等都需要不一样的jdbc呀！再有就查一下你用的jdbc驱动包是否合适你当前的sql版本，譬如说mysql5和之前的版本所需的jdbc好像就不一样的。

[MavenTalk]

数据库驱动jar包有问题

[Only_You_forver]

数据库的jar包也没有问题,一个已经导入到项目中了,
一个放在了tomcat中的lib中了

[cbynietg]

Cannot create JDBC driver of class '' for connect URL 'null'
java.sql.SQLException: No suitable driver
导入的驱动不合适.查看一下.

[SHSxj]

是不是classpath没配置啊，要不就有可能数据库没有更新。。。

[UZT85]

URL 'null'

检查配置代码

把代码贴出来！

[zktbduandd]

没有或到连接 驱动问题
1.驱动问题
2.连接池问题
3.获取程序中获得连接方式代码问题

[jack803]

数据库驱动包考到lib下

[fxy8glb]

我用的是myeclipse+tomcat5.0.9+sqlserver数据库，也报类似的错误，郁闷
