A gentle hint for Usenet - pick a subject line that hints at your question,
such as, "What happens when we start the server?"
Let's pick just one server, Apache Tomcat,
<http://tomcat.apache.org/>
There are so many that I couldn't talk about all of them in reasonable time.
Tomcat starts an instance of the JVM, then runs code to read its deployment
files, finally it settles into the configured port(s) and listens for incoming
requests.
When it receives a request, it uses the request URL to determine which
application should handle the request.
Applications are bundles of Java code and other resources that receive
requests, perform business logic and create responses, typically web pages, to
send back.
The server starts up certain bundles of Java code in the application called
servlets, made known to the server through another one of those deployment
files. The URL determines the servlet chosen, according to rules from the
deployment descriptor. The server creates or recalls an instance of that
servlet class and invokes its service() method, returning the constructed
response back to the client.
There are a lot more details available via the Tomcat link. GIYF.
