Yes. JSP technology lets the programmer to extend the jsp to make the programming more easier. JSP can be extended and custom actions & tag libraries can be developed to enhance/extend its features.

No, you cannot extend JavaServer Pages (JSP) technology directly. JSP is a technology that allows developers to create dynamic, platform-independent web applications. It is built on top of the Java Servlet API and provides a simplified, tag-based syntax for creating web pages.

However, if you want to extend the functionality of JSP, you can do so indirectly by incorporating other Java technologies and frameworks into your web application. For example, you can use JavaBeans, custom tags, and JavaServer Faces (JSF) to enhance the capabilities of your JSP-based application. Additionally, you can leverage other advanced Java technologies like Spring, Hibernate, or Apache Struts to implement more complex features.

In summary, while you cannot directly extend JSP itself, you can enhance your web application by integrating it with other Java technologies and frameworks.
