Using java methods in JSP

I want to call some methods in my jsp file. I have a class file with some methods and I want to use some of the methods used in that class file. I have gone through page import in JSP, but still I d开发者_如何学Pythonidn't get any idea about how to do that. I have installed some extra libraries and which is required to run those methods. Do I need to place the libraries in the server where I am using the jsp file. Can anyone suggest me how to do that..

• add the jars in WEB-INF/lib
• Avoid using java code in JSP, use EL and/or jsp:useBean isntead.

Use @page Directive tag to include the java class file and create object in scriptlet(<% %>) tag and use the methods of that class as you want..
