Servlets are pure java programs.here we can't use HTML.
But in JSP we use HTML,so we can use and modify the data
Servlets are faster than JSP.bcoz while running JSP
programs it will be converted into Servlets and then
executed,so it takes more time.
Both servlet and jsp are web components. But servlet is
best suited for request processing, handling the business
logic while jsp is suitable for content generating .Its
easy to include html tag in jsp rather than servlet.Also
jsp is compiled to servlet when first loaded to
webserver.So in many framework servlet act as a controller
while jsp as a view.Also implicit object and action
elements available in jsp but not in servlet.
Like we all know both jsp's and servlets are used in web
applications.The only difference is we have html embedded in
java code in case of servlets making use of implicit
response objects and in case of jsp's it is java code that
is embedded in html code i.e.,what we call business logic
using scriplets(<%,%>).We have different applications for
both jsp's and servlets when we talk about flexibility we
opt for jsp's.It is because in case of servlets both
business logic and presentation logic are given by the same
java file ,so any change in presentation logic wll lead to
the entire compilation of the java file and replacing the
.class file back in the servlet container.When it comes to
jsp's we have both application and presentation logic
seperated.So even if u modify the presentation logic we need
not compile or modify any content of servlet engine.We are
aware of the modern web technologies advancements every day
and more over in the competing market environment it is
necessary to modify the look and feel of the page constantly
.So we prefer jsp's rather than servlets most of the
times.I do agree that servlets finds its application in
many cases but still jsp's can do the job for us.
both servlet and JSP are same.Both are using to represent a
dynamic content to the user but their job is different.And
servlets are used for business logic whereas JSP are used for
presentation logic.If u want to present the data to the user once using servlets what you do is you put HTML with in java.if you want to present the data to the user once using JSP what you do is you put java with in HTML
1)jsp is the tag oriented where as servlet are not the tag
2)for the servlet mpping is required where as for jsp no
mapping is required.
3)jsp files are saved by .jsp extension where as servlet
files are saved by .java extension.
4)servlets are more faster than jsp.
The main difference between jsp and servlet is that in
servlet we write html code in java class and in jsp we write
java code in html page.Servlet is a java class.According to
MVC(model,view,controller) pattern servlet is used as
controller while JSP is used as view.
