The following article explains When should we use Java Servlets.

In general, Java Servlets are a useful tool for developing web applications in Java. The following list show some situations where you might want to consider using Java Servlets.

  1. When you need to handle HTTP requests and responses. In fact, servlets are designed to handle HTTP requests and responses, which makes them a good choice for web applications that need to process user requests and generate dynamic content in response.
  2. When you need to generate dynamic content. Moreover, servlets can be used to generate dynamic HTML pages, JSON, XML, or other types of content on the fly, on the basis of user input or other factors.
  3. When you need to interact with databases. Likewise, we can use servlets to access databases and other data sources, making them a good choice for web applications that need to store or retrieve data.
  4. When you need to handle concurrency. Servlets are designed to handle multiple concurrent requests, which makes them a good choice for web applications that need to handle a large number of users at once.
  5. When you need to integrate with other Java technologies. Actually, Servlets are a part of the Java Enterprise Edition (Java EE) platform, which means they can be easily integrated with other Java technologies, such as JavaServer Pages (JSP), JavaBeans, and Enterprise JavaBeans (EJB).

In summary, if you are developing a web application in Java that needs to handle HTTP requests and generate dynamic content, interact with databases, handle concurrency, and integrate with other Java technologies, then Java Servlets can be a good choice for your project.
