In servlet,java will be used to generate dynamic HTML pages,but in JSP,java will be reduced and we can use our custom tags to generate HTML pages.

Question:
What is the difference between servlets and Java Server Pages? Which is preferred?
Answer:
Servlets and Java Server Pages are complementary APIs, both providing a means for generating dynamic Web content. A servlet is a Java class implementing the javax.servlet.Servlet interface that runs within a Web or application server's servlet engine, servicing client requests forwarded to it through the server. A Java Server Page is a slightly more complicated beast. JSP pages contain a mixture of HTML, Java scripts (not to be confused with JavaScript), JSP elements, and JSP directives. The elements in a Java Server Page will generally be compiled by the JSP engine into a servlet, but the JSP specification only requires that the JSP page execution entity follow the Servlet Protocol.

The advantage of Java Server Pages is that they are document-centric. Servlets, on the other hand, look and act like programs. A Java Server Page can contain Java program fragments that instantiate and execute Java classes, but these occur inside an HTML template file and are primarily used to generate dynamic content. Some of the JSP functionality can be achieved on the client, using JavaScript. The power of JSP is that it is server-based and provides a framework for Web application development. Rather than choosing between servlets and Java Server Pages, you will find that most non-trivial applications will want to use a combination of JSP and servlets. In fact, the JSP 1.1 and Servlet 2.2 specifications are based around the concept of the Web application, combining the two APIs into a unified framework.

JSP page has both presentation logic and business logic but servlet has only business logic and presentation logic is present in html file

Jsp is nothing but a servlet.jsp is transfered to servlet by jsp engine.after converting it acts like a servlet.in servlets static content and dynamic content are combined.we can avoid this using jsp.we can separate static content from dynamic content.so this makes the application very flexible.

Servlet contains very indepth coding to develop any servlet web application.And also all logics are implemented in same servlets we get page centric problem.There is no implicits objects and by default servlet is not a threadsafe.It is not participating session by default.javax.servlet package.

when compare to servlets....
In jsp,Indepth java coding is reduced because of custom tags is used.And Business,Data acess logics are developed in different webpages.It means presentation logics are developed in jsp page and data acess logic developed in JavaBean class.It eliminates pagecentric problem. Jsp have its own implicit objects provided by container.Bydefault its participating in session.It is the subpackage of javax.servlet.jsp package.But both are available in same server.

servlet:-1)mainly for business logic.
2)once compled a servlet,if any modifications then once again complie and re-deploy.
3)no implicit objects.

jsp:-1)mainly for presentation logic.
2)want to make changes go to the source jsp file and make changes,not need any recompilation.
3)implicit objects are there.

**** jsp== servlet ****

because,even if u write any jsp file at the back a servlet will be generated.
(for example if u r using tomcat as server then in "work directory "of tomcat there u can find the servlet.

servlet is runs on the server.It has only business logic. jsp is mixing of html and java.
JSP page has both presentation logic and business logic.
