1. Servlets are cross-platform:
Because servlets are written in Java, they can be used on multiple
platforms without worrying about compatibility issues or recompilation.
2. Servlets are fast:
Standard CGI programs are slow because a new process must start up and run
for every client request. For example: if a Perl cgi search engine is being
used by 25 users, 25 separate version of the program have to be loaded into
memory and executed... that's a lot of overhead.
Java servlets are fast because they are persistent. The same search engine
as a servlet would load only once and then service all 25 clients using
multiple threads. It would then stay loaded in memory and wait for more
requests instead of shutting down.
3. Servlets are elegant:
Because Java was created from the start to be object oriented, programs
written in that language tend be organized more effectively into easily
manageable parts. This makes servlets easier to maintain and understand.
4. Servlets are secure:
Servlets are run in the Java security sandbox so can be insulated from
disrupting the operating system or breaching security. Additionally, many
security holes in traditional CGI languages result from the those languages
being weakly typed. Java's strong typing helps to ensure fewer accidental
security mistakes.
