The Java Platform, Enterprise Edition 5 (Java EE 5) has two different but complementary
technologies for producing dynamic web content in the presentation tier—namely Java
Servlet and JavaServer Pages (JSP).
Java Servlet, the first of these technologies to appear, was initially described as extensions
to a web server for producing dynamic web content. JSP, on the other hand, is a newer technology
but is equally capable of generating the same dynamic content. However, the way in
which a servlet and a JSP page produce their content is fundamentally different servlets
embed content into logic, whereas JSP pages embed logic into content.
