Title: What is Servlet?
1What is Servlet? Servlet
Servlet technology is utilized to make a web
application (dwells at server side and creates a
dynamic web page).
2Servlet technology is strong and adaptable as a
result of java language. Before Servlet, CGI
(Common Gateway Interface) scripting language
was prevalent as a server-side programming
language. Be that as it may, there were numerous
impediments of this technology. We have discussed
these weights underneath. There are various
interfaces and classes in the Servlet API, for
instance, Servlet, GenericServlet, HttpServlet,
ServletRequest, ServletResponse et cetera.
- What is a Servlet?
- Servlet can be depicted from various
perspectives, dependent upon the particular
condition. - Servlet is a technology i.e. used to make a web
application. - Servlet is an API that gives numerous interfaces
and classes including documentation. - Servlet is an interface that must be actualized
for making any servlet. - Servlet is a class that broadens the capacities
of the servers and reacts to the approaching
solicitations. It can react to a solicitations. - Servlet is a web segment that is sent on the
server to make a dynamic web page.
Do You Know?
- What is the web application and what is the
distinction amongst getting and Post ask? - What data is gotten by the web server in the
event that we ask for a servlet? - How to run servlet in Eclipse, MyEclipse and
Netbeans IDE? - What are the courses for servlet coordinated
effort and what is the distinction amongst
RequestDispatcher and sendRedirect() technique? - What is the contrast amongst ServletConfig and
ServletContext interface? - How numerous ways would we be able to keep up a
condition of a client? Which approach is
generally utilized as a part of web improvement? - How to tally an aggregate number of guests and
aggregate reaction time for a demand utilizing
Filter? - How to run servlet with explanation?
- How to make enrollment shape utilizing Servlet
and Oracle database? - How would we be able to transfer and download the
record from the server?
What is a web application? A web application is
an application open from the web. A web
application is made out of web parts like
Servlet, JSP, Filter and so forth and different
segments, for example, HTML. The web segments
ordinarily execute in Web Server and react to
the HTTP ask.
3- CGI(Common Gateway Interface)
- CGI technology empowers the web server to call an
outside program and pass HTTP ask for data to the
outer program to process the demand. For each
demand, it begins another procedure. - Inconveniences of CGI
- There are numerous issues in CGI technology
- If various customers builds, it sets aside more
opportunity for sending a reaction. - For each demand, it begins a procedure and a Web
server is restricted to begin forms. - It utilizes platform subordinate language e.g. C,
C, Perl.
- Preferred standpoint of Servlet
- There are numerous preferences of servlet over
CGI. The web compartment makes strings for taking
care of the numerous solicitations to the
servlet. Strings have a considerable measure of
advantages over the Processes, for example, they
share a common memory zone, lightweight, cost of
correspondence between the strings are low. The
basic advantages of the servlet are as per the
following - Better execution since it makes a string for
each demand, not process. - Portability since it utilizes Java language.
- Robust Servlets are overseen by JVM so we dont
have to stress over the memory spill, rubbish
accumulation and so forth. - Secure in light of the fact that it utilizes
java language - Visit us NIIT Pune
