Java Class - JSP

I have written a Java class with connection pooling; It simply executes a query and displays a resultset. How do I call it from JSP?(not as a bean, but just the class). I need to look at some examples of this type. Any links/books?.
Any or all help is appreciated.

U can instantiate the class in the JSp, import if it is in another package and call the methods of the class directly in the scriptlet.
