[ysblmm2003]

我用另一个程序测试了数据库的连接，但是出现了
java.sql.SQLException: No suitable driver
我把oracle中的classes12.jar放到了Tomcat 4.1\common\lib，环境变量也设了如下：
classpath;%JAVA_HOME%\lib;%TOMCAT_HOME%\common\lib;D:\software\jdbc\lib\classes12.jar
但是还是出现上面的错误，不知道那里错了？希望大家能帮帮忙

[chinadrencher]

classes12.zip吧?!

你主铁里内容是编译错误.你代码有问题.自己仔细检查一下

[ysblmm2003]

谢谢阿~
我在检查一下

[ysblmm2003]

不过还是不行。。郁闷了~
