[解决办法]
检查一下你的sql jdbc 的驱动安装正确没有,肯定是出在这个问题上了

请按如下提示进行检查一下:

安装在D盘的情况:

CLASSPATH %JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;D:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib\servlet-api.jar;

JAVA_HOME
D:\Program Files\Java\jdk1.5.0_08

path
%JAVA_HOME%\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\system32\Wbem


----------------------------------------


安装在c盘的情况:

CLASSPATH %JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib\servlet-api.jar;

JAVA_HOME
C:\Program Files\Java\jdk1.5.0_08

path
%JAVA_HOME%\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\system32\Wbem

//-------------------------------------------------------------------------


JSP 数据库开发配置说明:

1.Microsoft Sql Server 2000 标准版的安装;
2.Microsoft sql server 2000 sp3补丁的安装;
3:sql server 2000 JDBC Driver 的安装,而且在sql 运行的状态下安装;
4.配置系统环境变量:
CLASSPATH:
%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib\servlet-api.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msbase.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\mssqlserver.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msutil.jar;


[解决办法]
jdbc配置问题
[解决办法]
是你数据库驱动的问题
最好把库文件放到web应用目录下的lib里面
[解决办法]
需要配置环境变量的,还有就是要学会看报错信息呀
root cause

java.sql.SQLException: No suitable driver
提示出让你看看jdbc了估计如楼上所说。
