How do Servlets compare to CGI?
A couple advantages of Servlets over CGI:
Servlets
- don't start up a new process for each request coming in (traditional CGI scripts do!). Instead threads inside the same VM process are executed.
- are written in the Java language and you have access to all its API's
- are written in the Java language and are thus portable
- allow you to focus on your core business, lots of things are done behind the scene, like parsing and decoding form data.
- can talk to the webserver (cgi's can't)
- can be fired up when the webserver starts up and can share data among instances (useful if you want to implement DB connection pooling)
