jsp中如何执行下列程序？急！

[解决办法]
import yourclass
[解决办法]
找本书好好看看
[解决办法]
直接加进去就可以了！
[解决办法]
写一个jsp页面
<%
POITest poiTest = new POITest ();
//像下面这样来调用类里面的方法
poiTest.readExcelToDB2();
%>
[解决办法]
把代码夹在 <%代码内容%> 就行了
[解决办法]
<% import = "你用的包名+类名 "%>
<jsp: UseBean id= "随便起个名 " name= "你用的包名+类名 " scope= "request/session " />
调用时使用, id.method()即可。
[解决办法]
楼上正解，把代码夹在 <%代码内容%> 就行了，然后放在JSP里面
