Re: Servlet Vs CGI (both in Java)

[Srinivasan S (Systems Engineering Group)]

Numerous differences between them

1.      CGI will create each and every process for a request and cant be
        more efficient whereas servlet create only 1 process and shared

2.      All the variables are returned as string in CGI u need to take
        care in converting them, since servlets written in Java all the
        variables will be returned in the type they specified.

3.      When CGI start processing it is detached from server and cant take
        any advantage of server variables but servlet since resides in
        server can take advantage of this one.  I need somebody to more
        specific in this aspect of server variables as i dont know much
        about that.

4.      Java concept of "write once run anywhere" applies to serlvet too
        u can write a servlet in win95 and can run in any OS as u prefer.

        Hope somebody in the list may add more to this one.

Thanks
Srini
