假设JDK安装到C:\\JDK6, TOMCAT安装到c:\\Tomcat6
配置JAVA
1.系统变
量PATH
变量后添
加
C:\\JDK6\
bin
2.系统环
境变量添
加
JAVA_HOM E:c:\\JDK6
CLASSPATH:c:\\JDK6\\lib\\ tools.jar; c:\\JDK6\\lib\\ dt.jar;
TOMCAT 配置
1.环境变
量添加
TOMCAT
_HOME:
c:\\Tomcat
6
2.将
c:\\Tomcat
6\\commo
n\\lib\\serv
let-api.jar
添加到
CLASSPA
TH
3.Eclipse
配置
Tomcat
连接JDBC
1.把
sqljdbc.ja
r拷贝到
Tomcat的
Lib,JAVA

CLASSPA
TH要添加
此驱动
2.示例代
