java,jsp连接mysql

用 测试用例测试java 程序是否能连接上数据库
//LoadDriver
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
// Notice, do not import com.mysql.jdbc.*
// or you will have problems!

public class LoadDriver {
public static void main(String[] args) {
try {
// The newInstance() call is a work around for some
// broken Java implementations

Class.forName("com.mysql.jdbc.Driver").newInstance();
}
catch (Exception ex) {
System.out.println(ex);
}
}
}
方法：1.
下载版本：mysql-connector-java-5.0.2
将mysql-connector-java-5.0.2-bin.jar 拷贝到

JAVA的安装目录D:/Program/Java
D:/Program Files/Java/jre1.5.0_02/lib/ext 下
和D:/Program Files/Java/jdk1.5.0_02/jre/lib/ext下

这样测试用例LoadDriver可以运行,不会抛出异常.
2.将mysql-connector-java-5.0.2-bin.jar放入 WEB-INF/lib下
jsp测试页可以运行
