Calling a java method in jsp

Question

I have a java class which performs some operations on files. Since the java code is huge I don't want to write this code in jsp. I want to call the methods in jsp whenever required.

Please tell me the path where I need to keep this file. Also some example code how to use it would be helpful.

Answer 1

In the servlet (which runs before the JSP):

Person p = new Person(); // instantiate business object
p.init(...); // init it or something
request.setAttribute("person", p); // make it available to the template as 'person'

In the template you can use this:

your age is: ${person.age}  <%-- calls person.getAge() --%>
