invoke a java project from jsp button click event

Question

I have created a simple java project to draw the bar chart taking certain values from text file and named it as ChartAdvancedBar.java, now i need to invoke it when I press a button in JSP file.

I have added this java project within the libraries of my web project. How can I import this java project to one of my JSP files?

I have added a line:

<%@page import="ChartAdvancedBar.*"%>

But it is giving an error that ChartAdvancedBar doesn't found.

Where is the package name? It should be packagename.ChartAdvancedBar — Aman Arora, Jan 29 '14 at 10:07
And how are you invoking the java class? Can you explain a bit on that ? — Aman Arora, Jan 29 '14 at 10:08
One advice **do not use scriptlets `<% %>` in JSP.** See [How to avoid Java Code in JSP-Files?](http://stackoverflow.com/q/3177733/1031945) — Aniket Kulkarni, Jan 29 '14 at 10:31

Try

<jsp:useBean id="give id here like an object" class="Fully qualified name of class file">

tag then access method

Make sure it should be compiled before using this.
