Is servlet used to create Web application?
Servlet technology is used to create a web application (resides at server side and generates a dynamic web page). Servlet technology is robust and scalable because of java language. Before Servlet, CGI (Common Gateway Interface) scripting language was common as a server-side programming language.
Can we create Web application without servlet?
Yes, definitely. Java can seem rather paralyzing with all of its frameworks; however, you can certainly build great web applications by rolling your own infrastructure.
Is JSP better than servlet?
Servlet is faster than JSP. JSP is slower than Servlet because the first step in JSP lifecycle is the translation of JSP to java code and then compile. Servlet can accept all protocol requests. JSP only accept http requests.
What is the role of servlet in web application?
Servlets are the Java programs that run on the Java-enabled web server or application server. They are used to handle the request obtained from the webserver, process the request, produce the response, then send a response back to the webserver. Servlets work on the server-side.
What are the limitations of servlets?
Disadvantages of Servlet
- One servlet is loaded into JVM.
- When there is a request, there is a thread, not a process.
- Servlet is persistent until it destroys.
- Designing in a servlet is difficult and slows down the application.
- You need a JRE(Java Runtime Environment) on the server to run servlets.
What are the advantages of servlets over CGI?
The Advantages of Servlets Over “Traditional” CGI. Java servlets are more efficient, easier to use, more powerful, more portable, safer, and cheaper than traditional CGI and many alternative CGI-like technologies.
Can we use servlet without JSP?

Are servlets platform independent?
Servlets provide a component-based, platform-independent method for building Web-based applications, without the performance limitations of CGI programs. And unlike proprietary server extension mechanisms (such as the Netscape Server API or Apache modules), servlets are server- and platform-independent.
Is servlet the best choice for building web applications?
Sure, building traditional desktop and even mobile applications is all well and fine. But what if you want to leave your current background behind and start stepping on the web terrain? The good news is that the language ships with the fully-fledged Servlet API, which lets you build robust web applications without much hassle.

How do I get Started with servlets?
The best way to get started using servlets is with a concrete example. Thus, in the next few lines I’m going to build up a simple web application that will let customers sign up using a plain HTML form. Data submitted by customers will be collected by a servlet and validated at a very basic level through some static helpers.
How many servlets do I need to create per web app?
So the short answer is, you will create many servlets per webapp since each webapp will expose several use cases. [EDIT] Re-reading your question it seems as if you are using the term siteto mean page or view.
