用的是JdbcOdbc，已配置School系统数据源，尝试了网上好多方法，都没有解决，上火。。
这是tomcat出错信息：

这是JSP源码：
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn=DriverManager.getConnection("jdbc:odbc:School");
Statement stat=conn.createStatement();
String sql="insert into T_STUDENT(STUNO,STUNAME,STUSEX) values ('4','老虎','男')";
int i=stat.executeUpdate(sql);
out.println("cheng gong+ "+i+" hang");
stat.close();
conn.close();
