編寫3個JSP頁面：input.jsp、first.jsp和second.jsp，將3個JSP文件保存在同一個Web服務目錄中，input.jsp使用include動作標記加載first.jsp和second.jsp頁面。first.jsp頁面可以畫出一個表格，second.jsp頁面可以計算出兩個正整數的最大公約數。當first.jsp被加載時獲取input.jsp頁面中include動作標記的param子標記提供的表格的行數和列數，當second.jsp被加載時獲取input.jsp頁面中include動作標記的param子標記提供的兩個正整數的值。
(1) input.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>

<body>
使用include動作標記加載first.jsp頁面，畫出一個表格。<br>
<jsp:include page="first.jsp">
<jsp:param value="10" name="row"/>
<jsp:param value="20" name="col"/>
</jsp:include>
<br>
使用include動作標記加載second.jsp頁面，求兩個最大正整數的公約數。<br>
<jsp:include page="second.jsp">
<jsp:param value="64" name="firstNumber"/>
<jsp:param value="48" name="secondNumber"/>
</jsp:include>
</body>
</html>

out.print("<tr>");
for(int j=1;j<=col;j++){
out.print("<td>");
out.print(i*j);

out.print("</table>");

out.print("<br>"+firstNumber+"和"+secondNumber+"的最大公約數是：");
if(firstNumber<secondNumber){
int a=firstNumber;
firstNumber=secondNumber;
secondNumber=a;

while(firstNumber%secondNumber!=0){
int temp=firstNumber%secondNumber;
firstNumber=secondNumber;

out.print(secondNumber);
