一个Java连接数据库的问题

语言：java
数据库：oracle
用jdbc连接数据库。
我的源码如下：
import java.sql.*;

class jdbcTest{
public static void main(String[] args) throws SQLException{
//String source = "@jdbc:oracle:thin:192.168.0.169:1521:STUDY";
String sqlstr = "select * from project";
System.setProperty("jdbc.drivers", "sun.jdbc.odbc.JdbcOdbcDriver");
//Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection conn = DriverManager.getConnection("@jdbc:oracle:thin:192.168.0.169:1521:STUDY","xiaoxc","kusch");
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery(sqlstr);
while(rset.next()){
System.out.println(rset.getString(1));
}
stmt.close();
}

}
上面实例中，编译能够通过
但是执行是报错：
D:\>java jdbcTest
Exception in thread "main" java.sql.SQLException: No suitable driver
        at java.sql.DriverManager.getConnection(Unknown Source)
        at java.sql.DriverManager.getConnection(Unknown Source)
        at jdbcTest.main(jdbcTest.java:10)
哪位大虾能够告诉我为什么？
应该怎么修改呀？

查看你的驱动和oracle数据库是否匹配，最好用oracle自带的class12.jar
