JavaServer Pages referred to as JSP in short, is a Sun Microsystems specification for combining Java with HTML to
provide dynamic content for Web pages.

When you create dynamic content, JSPs are more convenient to write than HTTP servlets because they allow you to embed Java code directly into your HTML pages, in contrast with HTTP servlets, in which you embed HTML inside Java code.

JSP is part of the Java 2 Enterprise Edition (J2EE), and it enables you to separate the dynamic content of a Web page from its presentation.

It caters to two different types of developers: HTML developers, who are responsible for the graphical design of the page, and Java developers, who handle the development of software to create the
dynamic content.

Since JSP is part of the J2EE standard, you can deploy JSPs on a variety of platforms, including WebLogic Server.

In addition, third-party vendors and application developers can provide Java-Bean components and define custom JSP tags that can be referenced from a JSP page to provide dynamic content.
