下面是一个简单的JSP页面示例，其中包含了一个Javabean用于执行基本的四则运算。在这个例子中，我们将创建一个名为`CalculatorBean`的Javabean，并在JSP页面中使用它来计算两个数字的和、差、积和商。
创建一个名为`CalculatorBean.java`的Javabean类：
```java
package com.example.beans;
public class CalculatorBean {
private int num1;
private int num2;
private int sum;
private int difference;
private int product;
private double quotient;
public void setNum1(int num1) {
this.num1 = num1;
}
public void setNum2(int num2) {
this.num2 = num2;
}
public int getSum() {
return sum;
}
public int getDifference() {
return difference;
}
public int getProduct() {
return product;
}
public double getQuotient() {
return quotient;
}
public void calculate() {
sum = num1 + num2;
difference = num1 - num2;
product = num1 * num2;
if (num2 != 0) {
quotient = (double) num1 / num2;
} else {
quotient = 0;
}
}
}
```
然后，创建一个名为`index.jsp`的JSP页面：
```jsp
<%@ page import="
