Java Server Pages (JSP) is a server side technology for developing dynamic web pages. This is mainly used for implementing presentation layer (GUI Part) of an application. A complete JSP code is more like a HTML with bits of java code in it. JSP is an extension of servlets and every JSP page first gets converted into servlet by JSP container before processing the client’s request.
Below are the links of tutorial shared on JSP. If you are beginner then read them in the given sequence to understand the technology in a better way.
