Hey,

Why Do not we have main() method in servlets. In other words, without writing the main method we are able to run the servlet program. why is it possible throgh servlets ?

Regards,

Because Servlets are instantiated by the servlet container (ie Tomcat, Weblogic, etc).

There is a main method but it's not in the servlets themselves.
It's in the code for the container. Once started, it runs continuously, waiting for HTTP requests. When it receives one, as Gregg said, it instanciates a servlet to handle it.

servlet does't have main() method but it run under control of one application that is container, the container will take care about servlet execution.

One part of the specification is implemented by vendor and using the other part of the specification you are suppose to write the pluggable component (servlets) that would fit into the first specifications implementation (that is the container).So there is a main method ,but that lies with the container code and at later part of the flow your code gets enxcuted.
