You cannot extend any class in JSP because a JSP has no value to it on its own. It will only be useful when converted to a servlet and every servlet has to extend HTTPServlet. In this case HttpJspBase 
 
According to Java Language spec a class can extend one and only one class. So " No " a Jsp cannot extend any class. 
 
But a jsp can be made to extend our own servlet instead of container generated servlet by using 
 
<%@ page extend="package.className">  
 
but this servlet must satisfy all the rules that apply for the container generated HttpJspBase Servlet

We cannot implement an interface in a jsp but we can extend a class in JSP by using  extends attribute of the page directive.

extends="package.class"

The fully qualified name of the superclass of the Java class file this JSP file will be compiled to. Use this attribute cautiously, as it can limit the JSP container's ability to provide a specialized superclass that improves the quality of the compiled file.
