Which is better CGI or Servlet?
In CGI each arriving client request can generate a separate process while servlet, processes are not created needlessly and share the memory space of the JVM. Servlet is more secure than CGI as it uses Java. The speed, performance and efficiency of the servlet is better than CGI. CGI scripts can be directly processed.
What are the types of servlets in Java?
There are two main servlet types, generic and HTTP:

- HTTP servlets. Extend javax. servlet. HttpServlet. Have built-in HTTP protocol support and are more useful in a Sun Java System Web Server environment.

What are the advantages and disadvantages 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.
