Yes. All sorts of web Applications/websites can be created using JSP and Servlets
You cannot. You display JSP Pages using the help of Servlets. Servlets are of the background classes and you cannot display them
No. But, knowledge of Servlets would be an added advantage if you are learning JSPs

Servlets 3.0 and JSP 2.1
Yes, JSP (JavaServer Pages) and Servlets can be used together in a web application. Servlets handle the business logic and processing of requests, while JSP is used to create the user interface and generate dynamic content. Servlets can interact with JSP pages to pass data and control the flow of the application.
SERVLETS JSP 1. Servlet is a java class. 2. Servlet is a single instance multiple thread web application, In which HTML code can be included in java code. 3. In servlets the presentation logic and the B.logic is tightly coupled. 4. For every modification done in servlet program, we need to recompile and reload the application. 5. In servlets implicit objects are not available. 6. Servlets are supported to HTTP, FTP, and SMTP protocols. 7. Sevlets are need Deployment Descriptor file (web.xml) 1. Jsp is a file. 2. In jsp java code can be included in HTML code by using special tags. 3. In jsp's the presentation logic and B.logic are separated by defining the java beans. 4. If any modifications done in jsp's without recompiling and reloading , the modifications are reflected. 5. In jsp's implicit objects are available which is we can implement directly into jsp pages. 6. Jsp are supported to HTTP protocol only. 7. No need of Deployment Descriptor file (web.xml) rajus_1219@yahoo.co.in
STRUTs is a framework of technology of java based on JSP/Java Servlets PHP is another server scripting language
because JSP internally changes in servlet and then follow servlet life cycle, so it is slower than servlet
It is a good to know item. It is not mandatory or necessary. Basic knowledge of core Java is enough to learn JSP and Servlets.
JSP and servlets are used in when you are building a website that provides a server sided service, for example connecting to a database is a service. == == JSP/Servlets are java code that perform the backend operations for web pages. Such servlets run in a java container, such as JBoss or Tomcat. Where you would use these would be in a web-based environment where you wanted to run the backend on Java, as opposed to PHP, Perl, etc. As an example, eBay is run by JSP/Servlet technology. However, JSP/Servlet technology is much more complicated than scripting languages, but well worth learning.
