There is a scripting elements called as declarations in JSP page that you can use to declare variables or methods. The declaration enclosed with a <%! .... %>. As an example you:

Java Code:

<html>
...
...
<%!
public String say() {
    return "Hello there!";
}
%>
...
...
Hi, <%= say() %>
...
</html>

Note: using a scriptlets is considered as not a good practice when creating a JSP page. You'll need to separate between presentation and the logic of you page by combining a JSP page with a servlet.

You'll want to use them in a servlet which will then pass the information needed by the JSP to display.
The JSP shouldn't be doing the calling, it should (largely) just be getting view beans out of the request and using them to lay out the page.
