void jButton3_actionPerformed(ActionEvent e) {

try{
//加载驱动程序和数据库
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
String url="jdbc:microsoft:sqlserver://localhost:1433;"+"DatebaseName=vipquery";
Connection loginconnection= DriverManager.getConnection(url,"sa","");

//捕获异常
}
catch(ClassNotFoundException cnfex)
{
System.err.print("装载jdbc:odbc 失败");
cnfex.printStackTrace();
System.exit(1);
}

为一个按钮点击执行事件但在加载的时候抛出异常
