The software side is also comprised of several components, with at least an HTTP server. The HTTP server is able to understand HTTP and URLs. As hardware, a web server is a computer that stores web s...

Gone are the days of using traditional software development models such as the Waterfall model. In today’s fast-paced IT world Agile is a new way forward. So in this blog, I will discuss What is Agile methodology. After reading this blog, your understanding of Agile will be crystal clear. Why do we need Agile methodology? Before Agile came into the picture, we had the Waterfall model of software development. The waterfall model can be defined as a sequential process in the development of a system or software that follows a top-down approach. This model was a straight forward and linear model. The waterfall model had various phases such as Requirements Gathering, Software Design, Implementation, Testing, Deployment, and Maintenance. This model however suffered a few drawbacks such as follows: This model was too time-consuming. Unless you complete a particular stage, you cannot proceed to the further stages. This model was suitable only for projects where requirements are stable. The wor...

If you have worked with Spring MVC then you should know   what is a DispatcherServlet?   It's actually the heart of Spring MVC, precisely the C of MVC design pattern or Controller. Every single web request which is supposed to be processed by Spring MVC goes through DispatcherServlet. In general, it's an implementation of Front Controller Pattern which provides a single point of entry in your application. It handles all incoming requests. It is also the bridge between Java and Spring. Btw, the   DispatcherServlet   is like any other Servlet is declared in the web.xml with a URL pattern but the only special thing is that the URL pattern for dispatcher servlet is enough to map every single web request to DispathcherServlert. It is responsible for request handling by delegating requests to additional components of Spring MVC e.g. actual controller classes i.e. those which are annotated using   @Controller   or   @RestController   (in case of RESTful ...
