How to Call a Java Class in JSP
In this post, we will show you how to call a Java class from JSP.
Now, in the previous article, I mentioned that you wanted to minimize the scriptlets and declarations in a JSP.
You wanna avoid dumping thousands of lines of code in your JSP. Now, it’s okay to add small bits of script, small bits of declarations, but don’t overdo it.
So, in order to kinda help with this problem, you can refactor your code into a separate Java class or make use of MVC.
So the Java class will have all of our code, all of our business logic, and so on, and the JSP can simply make a call, let the Java code or the Java class do the heavy lifting, and then the JSP can get the results and continue on with its processing.
Development Steps
Create a Java class Create a JSP page Call Java methods from Java class into JSP page.
1. Create a Java class – Calculator.java I assume that you have already JSP application. Now you can create a Java class named Calculator.java and keep following code into it: package net.javaguides.jsp.tutorial ; public class Calculator { public int addition ( int num1 , int num2 ) { return (num1 + num2); } public int substraction ( int num1 , int num2 ) { return (num1 – num2); } public int multiplication ( int num1 , int num2 ) { return (num1 * num2); } public int division ( int num1 , int num2 ) { return (num1 / num2); } }
Create a JSP page – calculator.jsp Let’s create a calculator.jsp file and add the following code to it. Let’s import Calculator Java class and use its methods: <%@ page import = " net.javaguides.jsp.tutorial.Calculator " %> Here is a complete example which is calling Calculator Java class methods and displaying results on brower. <%@ page import = " net.javaguides.jsp.tutorial.Calculator " %> <%@ page language = " java " contentType = " text/html; charset=ISO-8859-1 " pageEncoding = " ISO-8859-1 " %> < html > < head > < meta charset = " ISO-8859-1 " > < title >Insert title here < body > <% Calculator calculator = new Calculator (); % > Addition of 20 + 10 = <%= calculator . addition( 20 , 10 ) % > < br >< br > Subtraction of 20 – 10 = <%= calculator . substraction( 20 , 10 ) % > < br >< br > Multiplication of 20 * 10 = <%= calculator . multiplication( 20 , 10 ) % > < br >< br > Division of 20/10 = <%= calculator . division( 20 , 10 ) % >

How to call a java function from a jsp
I require the username used by the user in my project be compared to other usernames already registered. The username should be distinct. For this the input is taken in newuser.jsp which in turn calls a function searchForUsername in SemanticSearch.java. When the new user is registering even the email id is checked for validation and later when the username is typed the above checking needs to be done. I have tried one way which is not working.Please point what mistake I am doing?
My code in SemanticSearch.java has constructor:
public SemanticSearch() {}
The following code follows after validation of email id.
My code in newuser.jsp is
SemanticSearch myclass=new SemanticSearch(); boolean rets=myclass.searchForUsername(username); if (rets==false) { alert(“Username already exists”); document.getElementById(“username”).value=””; document.getElementById(“password”).value=””; document.getElementById(“username”).focus(); }
During the click event of adduser button this function has to be called. But during the click function nothing seems to happen. Please help.
