tomcat连接数据库问题，急救

[YUNYUN_033]

import java.sql.*;
public class T {
public static void main(String[] args) throws Exception {
String sql = "select * from tb";
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection conn = DriverManager.getConnection("jdbc:microsoft:sqlserver://home:1433","sa","sa");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(sql);
while(rs.next()) {
Student s = new Student();
s.name = rs.getString(1);
s.id = rs.getInt(2);
System.out.println(s);
}

rs.close();
stmt.close();

}
}
class Student {
String name;
int id;
public String toString() {
return "Student--> name:[" + name + "], id:[" + id + "]";
}
}


这段测试的代码编译没有错误，但用java T命令就有错误了，是什么原因
Exception in thread "main" java.lang.ClassNotFoundException: com.microsoft.jdbc.

我已经把三个JAR包放在C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib里了

[比特灵]

这跟TOMCAT有关系？

[JIEK_ONE]

把三个JAR包的路径配置到你的CLASSPATH中

[YUNYUN_033]

classpath是配置的C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib下的路径的但个包吗，请给出一个详细点的，为什么有的人说把三个包配在了C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib里了，就不需要配置classpath了，请高手门给出一个详细点的答案行吗，谢谢了

[YUNYUN_033]

怎么没人回答啊，我配了classpath也没用啊

[high_java]

你把三个JAR包(msutil.jar,mssqlserver.jar,msbase.jar)放在TOMCAT 下


看我的环境变量配置CLASS_PATH=
F:\JAVA\JDK\lib\dt.jar;F:\JAVA\JDK\lib\tools.jar;F:\JAVA\Tomcat5.0\lib;F:\JAVA\Tomcat5.0\common\lib\msbase.jar;F:\JAVA\Tomcat5.0\common\lib\mssqlserver.jar;F:\JAVA\Tomcat5.0\common\lib\msutil.jar;

顺便说下哈，我配置都对，但是却有HTTP：500的提示错误，有高手的话，给解答下
